Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to a bracket for folding glasses of unequal thickness. Background Art
[0002] Unequal thickness folding glass is a special glass product with uneven thickness in various places and can adapt to folding scenes. Its typical structure is to set a groove in the middle of a single side of the glass, so that the groove area forms a folding area, and the two ends of the glass are relatively thick non-folding areas to meet the use requirements of the folding screen of electronic devices. In the preparation process of the above-mentioned unequal thickness folding glass, it is first necessary to prepare an acid-resistant film on the non-folding areas at both ends of the upper surface of the flat glass. The folding area in the middle area of the upper surface does not need to be provided with an acid-resistant film to expose the glass; the entire lower surface of the flat glass (including the non-folding area and the folding area) is prepared with an acid-resistant film; then the coated glass is inserted into the acid etching rack, and finally put into the etching liquid tank for etching. Since the acid-resistant film is not set locally on the upper surface of the glass, the exposed part will react with the etching liquid, thereby etching a groove of a preset depth on the upper surface of the glass. The rack with the folding glass is then cleaned to remove the acid-resistant film on the surface of the glass, thereby obtaining unequal thickness folding glass with a single-sided etched groove. For the folding glass with uneven thickness and grooves etched on both sides, the lower surface of the glass is processed in the same way as the upper surface of the glass, and the aforementioned etching and film stripping operations are repeated to obtain the folding glass with uneven thickness and grooves etched on both sides.
[0003] At present, in the acid etching, cleaning, and film stripping process of unequal thickness folding glass, it is necessary to load the glass on a bracket to realize batch processing of the glass. However, the common acid etching bracket (used as cleaning and film stripping at the same time) on the market mainly contacts the left and right sides and the bottom of the glass to realize the support of the glass. The ability of the structure to resist glass bending and deformation is low. In the etching liquid tank, the up and down tossing rack and the liquid bubbling process are added, and the unequal thickness folding glass will be folded and bent, causing the glass to extend out of the bracket and even break. In addition, when the unequal thickness folding glass moves out of the etching liquid level, the cleaning liquid level, and the film stripping layer liquid level, due to the surface tension of the liquid and the vertical stability of the vertically lifted glass, the unequal thickness folding glass is folded and bent and extends out of the bracket. The glass is difficult to move out of the liquid level vertically, which easily causes the folding glass to break, thereby reducing the yield of the unequal thickness folding glass.

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0023] Please combine Figure 1 and Figure 2The utility model discloses a bracket for folding glass of unequal thickness, which reduces the bending, deformation and shaking of glass caused by external disturbances and liquid tension during glass acid etching, cleaning and film stripping by comprehensively limiting and protecting the folding glass of unequal thickness, thereby reducing the problem of fragments caused by glass bending and shaking, so as to improve the yield of glass. Specifically, the bracket for folding glass of unequal thickness in this embodiment includes a fixing component, a supporting component and a limiting component, the fixing component includes two side panels 100 arranged opposite to each other, a first supporting plate 200 located at the front side of the two side panels 100 and fixedly connected to the two side panels 100 at both ends, and a second supporting plate 300 located at the rear side of the two side panels 100 and fixedly connected to the two side panels 100 at both ends, the two side panels 100, the first supporting plate 200 and the second supporting plate 300 together form a loading area. In this embodiment, when the bracket is placed on the external receiving surface and the two side panels 100 are respectively located on the left and right sides of the operator, the front side of the side panel 100 is the side where the operator is located, and the rear side of the side panel 100 is the side of the side panel 100 away from the operator, that is, the rear side is the opposite side of the front side. The connecting line of the middle parts of the two side panels 100 is perpendicular to the connecting line of the middle parts of the first support plate 200 and the middle parts of the second support plate 300, so that the two side panels 100, the first support plate 200 and the second support plate 300 surround a rectangular loading area. The first support plate 200 is provided with a plurality of first circular holes 210 connected to the loading area along the length direction of the first support plate 200 (that is, the length direction of the loading area), and the second support plate 300 is provided with a plurality of second circular holes 310 corresponding to each first circular hole 210, and each first circular hole 210 and its corresponding second circular hole 310 form a plug-in channel.
[0024] The support assembly includes at least one bottom support rod 400 received in the loading area and fixedly connected to the lower part of the two side panels 100, a first side contact rod 500 received in the loading area and fixedly connected to the two side panels 100 and adjacent to the first support plate 200, a second side contact rod 600 received in the loading area and fixedly connected to the two side panels 100 and adjacent to the second support plate 300, and at least one upper pressing plate 700 received in the loading area and detachably connected to the upper part of the two side panels 100. In this embodiment, the bottom support rod 400, the first side contact rod 500, the second side contact rod 600 and the upper pressing plate 700 jointly support and limit the glass to prevent the glass from shaking in the front-to-back direction and the up-and-down direction of the side panel 100. The upper surface of the bottom support rod 400 is provided with a plurality of loading notches 410 along the length direction of the bottom support rod 400. The loading notches 410 are deep groove structures to ensure the depth of the glass inserted into the loading notches 410 and to increase the contact area between the inner wall of the loading notches 410 and the glass, so as to prevent the glass from slipping out of the loading notches 410 during the processing. The lower surface of the upper pressing plate 700 is provided with a plurality of limiting notches 710 corresponding to each loading notch 410. The limiting notches 710 are triangular notches with a larger opening to reduce the difficulty of embedding the upper part of the glass into the limiting notches 710, thereby reducing the difficulty of installing the upper pressing plate 700. Each loading notch 410 and its corresponding limiting notch 710 together form an embedding position for embedding a single piece of glass, so as to clamp the glass, so that the bracket can load multiple pieces of glass in batches at one time for processing, thereby improving the efficiency of glass acid etching, cleaning and film stripping. A plug-in channel is provided between two adjacent embedding positions, and the plug-in channel is used to set the limiting component. The limiting assembly includes a plurality of limiting rods 800 which are arranged in correspondence with each other in each insertion channel and are connected to the first support plate 200 and the second support plate 300 respectively. That is to say, one end of the limiting rod 800 is inserted into a first circular hole 210, and the other end of the limiting rod 800 is inserted into a second circular hole 310 corresponding to the first circular hole 210, so as to separate the glass in two adjacent embedding positions to prevent the glass from shaking in the left and right directions of the bracket. In this way, the supporting assembly and the limiting assembly jointly limit the folding glass of different thicknesses, thereby realizing comprehensive protection and support for the folding glass of different thicknesses during the acid etching, cleaning and film stripping processes, thereby preventing the glass from breaking due to bending deformation and shaking. In addition, in the present embodiment, the limiting rod 800 includes a large diameter portion 810 corresponding to the non-folding area of the glass and a small diameter portion 820 corresponding to the folding area of the glass (etched groove on the glass), so as to prevent the limiting rod 800 from blocking the etched groove on the glass.
[0025] In order to improve the stability of the glass support, two bottom support rods 400 are arranged at intervals in the lower part of the loading area, and two upper pressure plates 700 are arranged at intervals in the upper part of the loading area to increase the support area of the support assembly for the glass. In this embodiment, the upper pressure plate 700 is installed on the two side panels 100 by means of a snap-on connection to achieve the limitation of the upper part of the glass. Specifically, at least one upper pressure groove extending downward from the top surface of the side panel 100 is provided on one side of the side panel 100 adjacent to the loading area, and the upper pressure groove includes at least one single groove 110, and the end of a single upper pressure plate 700 is correspondingly embedded in the single groove 110 in one upper pressure groove, that is, the same upper pressure groove on the side panel 100 is used to embed the same upper pressure plate 700. In other words, one upper pressure groove may include only one single groove 110 or multiple single grooves 110. When an upper pressing groove includes only one single groove 110, the upper pressing plate 700 used to cooperate with the upper pressing groove is directly embedded in the single groove 110; when the number of single grooves 110 included in the upper pressing groove is greater than one, multiple single grooves 110 are arranged in parallel and spaced apart and all extend downward from the top surface of the side plate 100. In this way, the operator can select one of the upper pressing plates 700 to be embedded in one of the single grooves 110 to adjust the installation position of the upper pressing plate 700 to adapt to different glass sizes.
[0026] In addition, when the same upper pressing groove includes multiple grooves, there are two situations: the projection lengths of multiple single grooves 110 in the height direction of the side plate 100 are the same, or the projection lengths of at least two single grooves 110 in the height direction of the side plate 100 are different. When the projection lengths of multiple single grooves 110 in the height direction of the side plate 100 are the same, the upper pressing plate 700 can be adjusted by embedding the single groove 110 at a preset position to abut against the preset position on the glass. When at least two single grooves 110 have different projection lengths in the height direction of the side plate 100 (that is, at least two single grooves 110 have different depths), the upper pressing plate 700 can be embedded in single grooves 110 of different depths to adapt to the installation limit of glass of different height sizes and to adapt to the loading of glass of a certain height range. It should also be noted that the upper pressure plate 700 of this embodiment does not need to be fixed to the side plate 100 by screws. When taking and placing the glass, it is only necessary to lift the upper pressure plate 700 and take it away from the side plate 100, which reduces the difficulty of taking and placing the glass.
[0027] Please combine Figure 1 and Figure 3In one embodiment, a protrusion 120 in the middle area of the bottom of the single groove 110 is used to separate the bottom of the single groove 110 to form two spaced arc-shaped notches 130, and the lower part of the upper pressing plate 700 is embedded in an arc-shaped notch 130. In this way, when the upper pressing plate 700 is embedded in the single groove 110 and pressed downward, the lower part of the upper pressing plate 700 is embedded in the arc-shaped notch 130, and the upper inner side wall of the single groove 110 and the protrusion 120 at the bottom of the single groove 110 jointly clamp the upper pressing plate 700 to prevent the upper pressing plate 700 from shaking. While improving the reliability of the upper pressing plate 700 in limiting the glass, it prevents the problem of glass breakage caused by the shaking of the upper pressing plate 700 and impacting the glass.
[0028] In one embodiment, a first strip guide hole 140 extending along the front-to-rear direction of the side panel 100 is provided at the lower portion of the side panel 100, and an end portion of the bottom support rod 400 is embedded in the first strip guide hole 140 and can slide in the first strip guide hole 140 along the front-to-rear direction of the side panel 100; a second strip guide hole 150 and a third strip guide hole 160 extending along the front-to-rear direction of the side panel 100 are spaced apart above the first strip guide hole 140 on the side panel 100, an end portion of the first side contact rod 500 is embedded in the second strip guide hole 150 and can slide in the second strip guide hole 150 along the front-to-rear direction of the side panel 100, and an end portion of the second side contact rod 600 is embedded in the third strip guide hole 160 and can slide in the third strip guide hole 160 along the front-to-rear direction of the side panel 100. Furthermore, the support assembly also includes a first locking bolt 141, a second locking bolt 151 and a third locking bolt 161. The first locking bolt 141 passes through the first strip guide hole 140 and is inserted into the end of the bottom support rod 400, and the bolt cap of the first locking bolt 141 abuts against the edge of the first strip guide hole 140; the second locking bolt 151 passes through the second strip guide hole 150 and is inserted into the end of the first side-contact rod 500, and the bolt cap of the second locking bolt 151 abuts against the edge of the second strip guide hole 150; the third locking bolt 161 passes through the third strip guide hole 160 and is inserted into the end of the second side-contact rod 600, and the bolt cap of the third locking bolt 161 abuts against the edge of the third strip guide hole 160. In this way, the first locking bolt 141 can be loosened and the position of the bottom support rod 400 can be adjusted. When the bottom support rod 400 moves to abut against the edge of the glass to be processed, the first locking bolt 141 can be tightened to adapt to folding glasses of different widths and thicknesses, so that the glass remains horizontal and avoids tilting of the glass. The second locking bolt 151 and the third locking bolt 161 can be loosened and the positions of the first edge contact rod 500 and the second edge contact rod 600 can be adjusted accordingly. When the first edge contact rod 500 and the second edge contact rod 600 move to abut against the edge of the glass to be processed, the second locking bolt 151 and the third locking bolt 161 can be tightened to adapt to the changes in the external dimensions of the folding glasses of different thicknesses.
[0029] In this embodiment, the gap between the large diameter portions 810 of two adjacent stopper bars 800 is greater than the thickness of the non-folding area of the glass. The gap between the large diameter portions 810 of two adjacent stopper bars 800 is 0.1-1 mm larger than the thickness of the unequal thickness folding glass after coating. For example, if the thickness of the non-folding area of the unequal thickness folding glass after coating is 0.22 mm, then the gap between the large diameter portions 810 of adjacent stopper bars 800 is 0.32-1.22 mm. The diameter difference between the large diameter portion 810 and the small diameter portion 820 is 1-16 mm. Since the etching groove on the glass is generally arranged in the middle of the glass, in this embodiment, the small diameter portion 820 is arranged in the middle of the stopper bar 800, and a large diameter portion 810 is arranged at each end of the stopper bar 800.
[0030] In one embodiment, a gripping hole 170 is provided on the upper portion of the side panel 100 facing away from the loading area. The gripping hole 170 provides a gripping position for manually or mechanically gripping the bracket when the bracket is moved. On the other hand, the gripping hole 170 is also used as a weight-reducing hole to reduce the overall weight of the bracket and reduce the difficulty of moving the bracket. Furthermore, in this embodiment, the fixing assembly also includes a first crossbeam 180 located below the first support plate 200 and fixedly connected to the two side panels 100, and a second crossbeam 190 located below the second support plate 300 and fixedly connected to the two side panels 100. By providing the first crossbeam 180 and the second crossbeam 190, a secondary connection of the two side panels 100 is achieved to improve the stability of the entire bracket structure and prevent the bracket from deforming.
[0031] The bracket for folding glass of unequal thicknesses of the utility model can simultaneously realize the support and limitation of the bottom, both sides and top of the folding glass of unequal thicknesses by setting the bottom support rod 400, the first side contact rod 500, the second side contact rod 600 and the upper pressure plate 700, thereby improving the stability of the glass support and realizing the protection of the glass against bending and deformation. At the same time, by setting the limiting rod 800 between two adjacent pieces of glass, it can prevent the glass from bending in the horizontal direction and the glass from shaking due to the tossing of the bracket during the cleaning process. At the same time, it can also reduce the problem of glass breakage caused by the folding glass of unequal thicknesses being folded and bent and extending out of the bracket due to the stirring flow direction of the liquid and the surface tension of the liquid surface when the etching liquid, the cleaning liquid and the film stripping layer liquid are removed from the folding glass of unequal thicknesses, and the glass cannot be moved vertically out of the liquid surface. The bending and deformation of the glass during the etching and leaving the liquid surface process is reduced, and glass fragments are reduced, thereby improving the glass yield.

To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
