Description

Technical Field

[0001] The invention relates to the field of glass processing equipment, and in particular to a glass strengthening clamp. Background Art

[0002] As the mobile market continues to expand, the technology of mobile terminals has also achieved breakthrough developments, the most representative of which is the foldable smartphone.

[0003] Foldable smartphones use OLED (Organic Light-Emitting Diode) panels, so they need to use ultra-thin glass. Ultra-thin glass is used to attach to the screen of smart devices to provide screen protection, and its thickness is about 30-100 microns.

[0004] However, as the thickness of the glass decreases, fine scratches are easily generated on its surface during use, and it is easy to break, which requires a strengthening process for the ultra-thin glass.

[0005] like Figure 1 As shown, in the prior art, grooves are provided as fixtures. After high-temperature strengthening of the ultra-thin glass, when it is cooled at room temperature, the temperature of the glass and the fixture is not evenly cooled, and cracks are easily generated at the part of the glass in contact with the fixture. In addition, stress is not uniform between the part where the fixture contacts the ultra-thin glass and the part where it does not contact, which may cause the ultra-thin glass to curl or reduce its strength. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a glass strengthening fixture, which can reduce the contact area between the glass and the fixture, and when the glass is cooled after the strengthening process, the glass temperature is uniformly reduced to prevent cracks from occurring, thereby improving the glass yield.

[0007] A glass strengthening fixture according to an embodiment of the present invention includes a frame, a bracket and a supporting rope. The bracket is connected to the frame, and the two opposite sides of the bracket are the near side and the far side. The bracket is provided with an avoidance concave area at the near side. There are at least two avoidance concave areas and they are distributed along the length direction of the bracket. The bracket is provided with a support group corresponding to each avoidance concave area. The support group includes a first support part and a second support part arranged around the avoidance concave area. The first support part is located at or adjacent to the near side. The first support part is provided on both sides of the avoidance concave area. The second support part is arranged close to the far side relative to the first support part, and the second support part is located between the first support parts on both sides in the length direction of the bracket. Adjacent support groups share one first support part. The support rope is wound around at least two support groups. The support rope corresponding to each support group includes: a first rope segment and a second rope segment. The first rope segment is connected between the second support part and the first support part on one side, and the second rope segment is connected between the second support part and the first support part on the other side. The projections of the first rope segment and the second rope segment on the surface where the avoidance concave area is located intersect, and the intersection point is located in the avoidance concave area. The first rope segment and the second rope segment are used to support the edge of the glass.

[0008] According to the glass strengthening clamp of the embodiment of the present invention, the support rope is connected to the support group through the first rope segment and the second rope segment to form a V-shaped groove, so that the edge of the glass can be inserted into the V-shaped groove for limiting. Since the first support part and the second support part are staggered along the length direction of the bracket, the first rope segment and the second rope segment can intersect on the projection of the surface where the avoidance concave area is located, and the intersection point is in the avoidance concave area. The intersection point is exactly the vertex of the V-shaped groove. The vertex is in the avoidance concave area, so the edge of the glass can also be supported in the avoidance concave area to avoid the edge of the glass from hitting the bracket as much as possible. When the glass is strengthened, the V-shaped groove formed by the first rope segment and the second rope segment is used to support the glass, so that the contact between the support rope and the edge of the glass is point contact as much as possible. When the glass is strengthened and cooled, the glass strengthening clamp can make the overall temperature of the glass drop evenly, preventing the glass crack problem caused by the excessive contact area between the clamp and the glass, so as to improve the yield rate of the glass. Here, the first support part and the second support part are arranged around the avoidance concave area, and the first support part and the second support part are staggered along the length direction of the bracket. Compared with other layout methods of the support group, the length of the support rope can be reduced, and the apex of the V-shaped groove can be close to the edge of the avoidance concave area. In this way, when the glass is subjected to a large impact, the glass can contact the edge of the avoidance concave area as soon as possible to avoid large shaking of the glass. The avoidance concave area and the support group are set to at least two, and the bracket can support at least two pieces of glass, thereby improving the utilization rate of the glass strengthening clamp. In addition, the adjacent support groups share the first support part, which is used to improve the compactness of the support group setting on the bracket, so that more support groups can be set to support more glass when the bracket is of the same length.

[0009] In some embodiments, a single support rope is wound around a single support group to form the first rope segment and the second rope segment.

[0010] In some embodiments, the first supporting portion is provided with a first hanging groove for positioning the supporting rope.

[0011] In some embodiments, the second supporting portion is provided with a second hanging groove for positioning the supporting rope.

[0012] In some embodiments, the first supporting portion and the second supporting portion are formed by bending a portion of the bracket in the same direction.

[0013] In some embodiments, the frame includes two panels, the two panels are spaced apart along the length direction of the bracket, and the bracket is connected between the two panels.

[0014] Furthermore, both panels are provided with long holes, and two ends of the bracket are respectively matched at the long holes, and the position of the bracket along the long holes is adjustable.

[0015] In some embodiments, there are multiple supports, which are respectively: a left support, a right support, a lower support and an upper support. The right side of the left support is provided with the avoidance recess and the support rope to support the left edge of the glass; the left side of the right support is provided with the avoidance recess and the support rope to support the right edge of the glass; the top of the lower support is provided with the avoidance recess and the support rope to support the lower edge of the glass; the bottom of the upper support is provided with the avoidance recess and the support rope to support the upper edge of the glass.

[0016] Optionally, one end of the upper bracket is rotatably connected to the panel, and the other end of the upper bracket is detachably connected to the panel.

[0017] In some embodiments, the bracket is arranged with at least two avoidance recesses along the length direction of the bracket, at least two support groups are correspondingly provided on the bracket, two adjacent support groups share the first support portion, and the support rope is sequentially wound around all the support groups along the length direction of the bracket.

[0035] Reference below Figure 2-Figure 7 A glass strengthening jig 100 according to an embodiment of the present invention will be described.

[0036] like Figure 2-Figure 3As shown, the glass strengthening fixture 100 according to an embodiment of the present invention includes: a frame 10, a bracket 20 and a support rope 30. The bracket 20 is connected to the frame 10, and the two opposite sides of the bracket 20 are a near side 21 and a far side 22. The bracket 20 is provided with an avoidance recess 23 at the near side 21. A support group 24 is provided on the bracket 20 corresponding to the avoidance recess 23. The support group 24 includes a first support portion 241 and a second support portion 242 arranged around the avoidance recess 23. The first support portion 241 is located at or near the near side 21. The first support portion 241 is provided on both sides of the avoidance recess 23. The second support portion 242 is provided near the far side 22 relative to the first support portion 241, and the support group 24 is provided in the length direction of the bracket 20 (such as Figure 2 The second support portion 242 is located between the first support portions 241 on both sides in the front-to-back direction. The support rope 30 is wound around the support group 24, and the support rope 30 includes: a first rope segment 31 and a second rope segment 32. The first rope segment 31 is connected between the second support portion 242 and the first support portion 241 on one side, and the second rope segment 32 is connected between the second support portion 242 and the first support portion 241 on the other side. The projections of the first rope segment 31 and the second rope segment 32 on the surface where the avoidance recessed area 23 is located intersect, and the intersection point is located in the avoidance recessed area 23. The first rope segment 31 and the second rope segment 32 are used to support the edge of the glass.

[0037] That is, the bracket 20 is connected to the frame 10, and the frame 10 is the support base of the glass strengthening fixture 100. A relief recess 23 is provided at the near edge 21 of the bracket 20, and a support group 24 is provided corresponding to the relief recess 23. The support rope 30 is wound around the support group 24 to support the edge of the glass. When the edge of the glass contacts the support rope 30, the support rope 30 can support and clamp the glass on the glass strengthening fixture 100, and the support rope 30 can provide support force for the glass, and at the same time, the edge of the glass will also apply pressure to the support rope 30.

[0038] The support rope 30 is connected to the support group 24 through the first rope segment 31 and the second rope segment 32. It is understandable that the first rope segment 31 and the second rope segment 32 may or may not be in contact, but the projections of the first rope segment 31 and the second rope segment 32 on the surface where the avoidance recess 23 is located can intersect to form an intersection, so that the support rope 30 can form a V-shaped groove through the first rope segment 31 and the second rope segment 32, and the opening direction of the V-shaped groove is consistent with the opening direction of the avoidance recess 23, so that the edge of the glass can be inserted into the V-shaped groove for position limiting. The intersection is exactly the vertex of the V-shaped groove. If the vertex is in the avoidance recess 23, the edge of the glass can also be supported at the avoidance recess 23, and the edge of the glass can be prevented from hitting the bracket 20 as much as possible.

[0039] The first support portion 241 is located at or near the proximal edge 21, and is used to connect the support rope 30. For example, in some solutions, the first support portion 241 is located near the proximal edge 21 of the bracket 20, and the first support portion 241 can be separately provided on the bracket 20, and the position of the first support can be adjusted as needed. In other solutions, the first support portion 241 is located at the proximal edge 21 of the bracket 20, and the first support portion 241 can be formed by a part of the bracket 20, so that the first support portion 241 can be processed during the production process of the bracket 20, which can reduce the structural complexity of the bracket 20.

[0040] When the glass is being strengthened, the intersection formed by the first rope segment 31 and the second rope segment 32 can support the glass. And because the contact between the support rope 30 and the edge of the glass is point contact, during the cooling process after the glass is strengthened, the glass strengthening fixture 100 can evenly reduce the temperature of the entire glass, preventing the glass crack problem caused by the excessive contact area between the fixture and the glass, thereby improving the glass yield rate.

[0041] The first support part 241 is disposed on both sides of the avoidance recess 23, and the second support part 242 is located between the first support parts 241 on both sides. The first rope segment 31 and the second rope segment 32 of the support rope 30 intersect, so that the glass can be supported between the first rope segment 31 and the second rope segment 32. And because the support rope 30 is wound between the first support part 241 and the second support part 242, the second support part 242 is disposed in the avoidance recess 23 of the bracket 20. Therefore, when the support rope 30 supports the glass, a certain gap is formed between the edge of the glass and the bracket 20, so as to reduce the contact area between the glass and the glass strengthening fixture 100, thereby increasing the yield rate of the glass after the strengthening process.

[0042] Here, the first support portion 241 and the second support portion 242 are arranged around the avoidance recess 23, and the first support portion 241 and the second support portion 242 are staggered in the length direction of the bracket 20. The second support portion 242 and the first support portions 241 on both sides are roughly arranged in a V shape. This arrangement forms a V-shaped groove, which is beneficial to reducing the length of the support rope 30.

[0043] In order to show that the present application scheme is conducive to shortening the rope length, the present application scheme is compared with another arrangement of the support group 24. In the other arrangement scheme, the line connecting the first support portion 241 and the second support portion 242 is perpendicular to the length direction of the bracket 20. Assuming that there are first support portions 241 and second support portions 242 on both sides of the avoidance recess 23, and the first support portion 241 is located in front of the second support portion 242, to form a V-shaped groove, the first rope segment 31 needs to be connected from the left front first support portion 241 to the right rear second support portion 242, and the second rope segment 32 needs to be connected from the right front first support portion 241 to the left rear second support portion 242. Moreover, if the first rope segment 31 and the second rope segment 32 are wound by the same support rope 30, the support rope 30 may also need to be connected between the first support portion 241 and the second support portion 242 on the same side. After this comparison, to form a V-shaped groove of the same size, the support rope 30 used in the present application scheme is more economical.

[0044] In addition, the solution of the present application can also make the apex of the V-shaped groove close to the edge of the avoidance concave area 23, so that when the glass is subjected to a large impact, the glass can contact the edge of the avoidance concave area 23 as soon as possible to avoid large-scale shaking of the glass. In particular, when the glass strengthening fixture 100 can support multiple pieces of glass, if a piece of glass is impacted, the solution of the present application can be used to limit the glass to a smaller range. When there is no impact, the edge of the glass is supported by the first rope segment 31 and the second rope segment 32 in a suspended state. When there is an impact, the edge of the glass can be supported by the edge of the avoidance concave area 23 to reduce the shaking amplitude.

[0045] In the solution of the present application, the bracket 20 is provided with at least two avoidance recesses 23 at the near edge 21, and a support group 24 is correspondingly provided at the periphery of each avoidance recess 23. The support rope 30 is wound around at least two support groups 24, so that the bracket 20 can support at least two pieces of glass, thereby improving the utilization rate of the glass strengthening clamp 100.

[0046] Specifically, adjacent support groups 24 share a first support portion 241, which can improve the compactness of the support groups 24 on the bracket 20, so that more support groups 24 can be arranged on the bracket 20 with the same length to support more glass. Figure 2 In the example, there are N avoidance recesses 23 (N is a natural number greater than 2) provided on the bracket 20, there are also N second support portions 242, there are (N+1) first support portions 241, and every two adjacent support groups 24 share a first support portion 241, so the number of first support portions 241 is saved, and the size occupied in the length direction of the first support portion 241 is small, so that two adjacent V-grooves can be arranged closer.

[0047] like Figure 4As shown, in some embodiments, a single support rope 30 is wound around a single support group 24 to form a first rope segment 31 and a second rope segment 32. In this way, winding a single support rope 30 around a single support group 24 can reduce the number of support ropes 30 and reduce production costs. In addition, using a single support rope 30 can prevent the support ropes 30 from being entangled with each other during the winding process, thereby reducing the difficulty of winding and increasing the yield rate of the glass strengthening fixture 100.

[0048] In actual use, since the first rope segment 31 and the second rope segment 32 are wound by a single support rope 30, the support structure is simplified, which can increase the stability of the glass strengthening clamp 100 and thus increase its service life.

[0049] In some embodiments, the first support portion 241 is provided with a first hanging groove 2411 for positioning the support rope 30. When the support rope 30 is connected to the first support portion 241, the first hanging groove 2411 can be used to position the support rope 30. And after the support rope 30 is connected to the first support portion 241, the support rope 30 can be fixed. In this way, when the support rope 30 supports the edge of the glass, the position of the support rope 30 can be limited by the first hanging groove 2411 to prevent the support rope 30 from being displaced when it is subjected to the pressure of the glass.

[0050] Preferably, two first hanging grooves 2411 are provided on the first support portion 241, and the two first hanging grooves 2411 are arranged along the length direction of the bracket 20. After the support rope 30 passes around the first hanging groove 2411 on one side of the first support portion 241, it can continue to surround the first support portion 241 and then pass around the first hanging groove 2411 on the other side. At this time, the support rope 30 is further positioned by the first hanging groove 2411 on the other side, and is more firmly fixed on the first support portion 241 to achieve support of heavier glass, so that the glass strengthening fixture 100 can process more glass in a single strengthening process, thereby increasing production efficiency.

[0051] Similarly, in some embodiments, the second support portion 242 is provided with a second hanging groove 2421 for positioning the support rope 30. For the same reason as the first support portion 241, the second hanging groove 2421 is provided on the second support portion 242, and when the support rope 30 supports the edge of the glass, the position of the support rope 30 can be limited by the second hanging groove 2421, preventing the support rope 30 from being displaced when subjected to the pressure of the glass.

[0052] Also preferably, two second hanging grooves 2421 are provided on the second support portion 242, and the two second hanging grooves 2421 are arranged along the length direction of the bracket 20. The support rope 30 is further positioned by the second second hanging groove 2421, and is more firmly fixed on the second support portion 242, so as to support heavier glass, so that the glass strengthening fixture 100 can process more glass in a single strengthening process, thereby increasing production efficiency.

[0053] In the solution of the present application, the first hanging groove 2411 and the second hanging groove 2421 can have various shapes.

[0054] For example, in some embodiments, the first hanging groove 2411 and the second hanging groove 2421 may be grooves that match the cross section of the vertical length direction of the support rope 30. When the cross section of the support rope 30 is circular, the first hanging groove 2411 and the second hanging groove 2421 are semicircular grooves. When the support rope 30 is woven and has a polygonal cross section, the first hanging groove 2411 and the second hanging groove 2421 are polygons that match.

[0055] In some embodiments, the first hanging groove 2411 and the second hanging groove 2421 are shaped as openings slightly larger than the diameter of the support rope 30. When the support rope 30 needs to be connected, the support rope 30 can be inserted into the openings to achieve positioning and fixation of multiple support ropes 30.

[0056] It should be noted that the cross-sectional shape of the support rope 30 perpendicular to the length direction is not specifically limited here. For example, the cross-section of the support rope 30 may be circular, and in this case, the contact between the support rope 30 and the edge of the glass when supporting the edge of the glass is point contact. In this way, when the glass is subjected to the strengthening process, the smaller contact area can reduce the contact between the support rope 30 and the glass, and prevent the glass from cracking or deforming during the strengthening process. The support rope 30 can also be woven from multiple strands, and in this case, the cross-sectional area of ​​the support rope 30 may be polygonal. The support rope 30 is woven from multiple strands, which can increase the tensile strength of the support rope 30. When the glass strengthening fixture 100 supports the glass, the higher strength of the support rope 30 can enable the glass strengthening fixture 100 to bear a heavier weight of glass, and more glass can be processed in one strengthening process to improve production efficiency.

[0057] In some embodiments, the first support portion 241 and the second support portion 242 are formed by bending a portion of the bracket 20 in the same direction. When the bracket 20 is processed, the first support portion 241 and the second support portion 242 can be formed by bending a portion of the bracket 20. In this way, the first support portion 241 and the second support portion 242 can be integrally formed on the bracket 20, thereby simplifying the structure of the bracket 20, preventing problems from occurring during use, and facilitating the stability of the glass strengthening fixture 100.

[0058] Optionally, on the bracket 20 , two adjacent first support portions 241 may be bent in different directions.

[0059] When two adjacent first support parts 241 are bent in different directions, two first support parts 241 are formed on two side surfaces of the bracket 20. At this time, after being connected by the support rope 30, the projections of the first rope segment 31 and the second rope segment 32 on the surface where the avoidance recess 23 is located intersect, and the intersection is located in the avoidance recess 23, but on the projection surface perpendicular to the surface where the avoidance recess 23 is located, the first rope segment 31 and the second rope segment 32 do not intersect. When the support rope 30 supports the edge of the glass, the support points of the support rope 30 on both sides of the glass are staggered. In this way, the stress points of the glass on the support rope 30 can be dispersed from each other, preventing the problem of local stress concentration causing a decrease in glass strength during the strengthening process, thereby increasing the glass strengthening yield rate.

[0060] like Figure 3-Figure 4 As shown, in some embodiments, the bracket 20 includes: a support plate 25 and a reinforcing plate 26. A relief recess 23 is formed on one side of the support plate 25, and a first support portion 241 and a second support portion 242 are formed on the support plate 25. The reinforcing plate 26 is vertically connected to the other side of the support plate 25. The reinforcing plate 26 is provided, and the reinforcing plate 26 is perpendicular to the support plate 25. When the glass strengthening fixture 100 supports the glass, the reinforcing plate 26 is subjected to the pressure of the glass pressing vertically downward. Because the reinforcing plate 26 is vertically connected to the support plate 25, the reinforcing plate 26 can withstand greater pressure without deformation. As a result, the bracket 20 can support glass of greater weight, thereby increasing the stability of the glass strengthening fixture 100.

[0061] like Figure 5-Figure 7 As shown, in some embodiments, the frame 10 includes two panels 11, the two panels 11 are spaced apart along the length direction of the bracket 20, and the bracket 20 is connected between the two panels 11. Thus, the bracket 20 can be fixed to the frame 10 through the panel 11 to improve the stability of the bracket 20 on the frame 10, so that it can bear more glass, thereby increasing the output.

[0062] like Figure 7 As shown, further, both panels 11 are provided with long holes 111, and the two ends of the bracket 20 are respectively matched at the long holes 111, and the position of the bracket 20 along the long holes 111 is adjustable. Therefore, the bracket 20 can be slid in the long holes 111 to change the spacing between the two brackets 20, so that different specifications of glass can be strengthened without replacing a new glass strengthening fixture 100, so as to increase the expansibility of the glass strengthening fixture 100 and reduce the production cost.

[0063] In some embodiments, mounting holes are provided at both ends of the bracket 20, and the bracket 20 is connected to the panel 11 through a fixing member. The fixing member can fix the bracket 20 on the two panels 11 through the mounting holes at both ends of the bracket 20, so that the glass strengthening fixture 100 forms a whole, making the structure of the glass strengthening fixture 100 more stable and increasing the service life.

[0064] Optionally, the fixing member is a bolt and a nut, and the bolt is passed through the mounting hole and connected with the nut. Thus, through the threaded connection, the fixing member can fix the bracket 20 on the frame 10 to increase the stability of the connection.

[0065] Furthermore, both ends of the bracket 20 are fixed to the frame 10 by bolts. When a bracket 20 of a different specification needs to be replaced, the bracket 20 can be replaced by removing the bolts, thereby increasing the expandability of the glass strengthening fixture 100 .

[0066] Of course, the fixing member of the present application is not limited to the bolt, and can be adjusted according to the connection position and connection mode of the fixing member. For example, the fixing member can be a fixing pin, and the bracket 20 is rotatably connected to the frame 10 by the fixing pin.

[0067] Optionally, the fixing member has a tightened state and a loose state, and when the fixing member is in the loose state, the position of the fixing member is adjustable along the length direction of the long hole 111. Therefore, when the fixing member is in the loose state, the bracket 20 can be slid in the long hole 111 to change the distance between the two brackets 20. In this way, glasses of different specifications can be strengthened without replacing a new glass strengthening fixture 100, thereby increasing the expandability of the glass strengthening fixture 100 and reducing production costs.

[0068] Optionally, the frame 10 includes a plurality of connecting rods 12, and the plurality of connecting rods 12 are connected between the two panels 11. The connection of the two panels 11 by the connecting rods 12 can make the structure of the frame 10 more stable, so that it can bear the weight of more glass, thereby processing more glass in one strengthening process to increase the output.

[0069] Further optionally, the two ends of the plurality of connecting rods 12 are connected to the four corners of the two panels 11. In this way, when the glass is fixed and the glass strengthening fixture 100 is removed, the frame 10 can be made more stable without affecting the loading and unloading of the glass.

[0070] like Figure 2As shown, in some embodiments, there are multiple brackets 20, which are respectively: a left bracket 20a, a right bracket 20b, a lower bracket 20c and an upper bracket 20d. The right side of the left bracket 20a is provided with an escape recess 23 and a support rope 30 to support the left edge of the glass. The left side of the right bracket 20b is provided with an escape recess 23 and a support rope 30 to support the right edge of the glass. The top of the lower bracket 20c is provided with an escape recess 23 and a support rope 30 to support the lower edge of the glass. The bottom of the upper bracket 20d is provided with an escape recess 23 and a support rope 30 to support the upper edge of the glass. Through the brackets 20 arranged in four directions, the four edges of the glass can be supported, so that the glass is fixed more firmly in the glass strengthening fixture 100. In the glass strengthening process, after the glass temperature is raised to the target temperature, it is generally necessary to quickly cool the glass by air cooling. Fixing the glass more firmly on the glass strengthening fixture 100 can prevent the glass from shaking during the cooling process, thereby improving the yield rate.

[0071] Optionally, the number of the left bracket 20a, the right bracket 20b, the lower bracket 20c and the upper bracket 20d can be multiple. When the glass strengthening fixture 100 supports a large number of glasses and is heavy, the multiple brackets 20 can provide greater support for the glass, making the glass strengthening fixture 100 more stable.

[0072] Optionally, the bracket 20 may include an upper left bracket, a lower left bracket, an upper right bracket and a lower right bracket. When the glass to be strengthened is of a special shape, the brackets 20 arranged in multiple directions can provide better support for the glass, thereby improving the expansibility of the bracket 20 for strengthening the glass.

[0073] Optionally, one end of the upper bracket 20d is rotatably connected to the panel 11, and the other end of the upper bracket 20d is detachably connected to the panel 11. In this way, the upper bracket 20d can be rotated by removing one end of the upper bracket 20d, so that the glass can be taken out or put in more conveniently, thereby increasing the production efficiency of the glass strengthening fixture 100.

[0074] Of course, in some other embodiments, both ends of the upper bracket 20d are detachably connected to the panel 11. In this way, the glass can be taken out or put in by directly disassembling the upper bracket 20d, thereby increasing the production efficiency of the glass strengthening fixture 100.

[0075] In some embodiments, the bracket 20 is provided with at least two avoidance recesses 23 along the length direction of the bracket 20, and at least two support groups 24 are provided on the bracket 20 accordingly, and two adjacent support groups 24 share a first support portion 241, and the support rope 30 is sequentially wound on all the support groups 24 along the length direction of the bracket 20. By using at least two support groups 24, it is possible to achieve a support portion for supporting the edge of the glass by winding a support rope 30. The support rope 30 is wound along the length direction of the bracket 20, and each avoidance recess 23 can support a piece of glass. In this way, multiple avoidance recesses 23 can be provided on the bracket 20 to support multiple pieces of glass, so as to improve the production efficiency of the glass strengthening fixture 100.

[0076] In the solution of the present application, the frame 10, the bracket 20, and the support rope 30 are all made of anti-corrosion materials, so that the glass strengthening clamp 100 can maintain a long service life even when it is stuck to acid liquid.
