Description

Technical Field

[0001] This utility model relates to the field of touch screen glass panel production technology, specifically to a device for preventing scratches from overlapping glass panels. Background Technology

[0002] Touchscreen glass panels are one of the core components enabling touch interaction in modern electronic devices, and are widely used in smartphones, tablets, ATMs, industrial control panels, and other devices. During the tempering process of mobile phone cover glass, the glass sheet undergoes high-temperature ion exchange in a tempering furnace. The purpose is to significantly improve its mechanical strength (impact resistance, scratch resistance, etc.) by altering the chemical structure of the glass surface.

[0003] like Figure 2 In existing technologies, the placement rack has a partition plate with multiple evenly spaced dividing teeth. Multiple glass sheets are stacked on the placement rack, and the dividing teeth separate the glass sheets. The placement rack is then sent into a tempering furnace for high-temperature treatment. However, in existing technologies, the spacing between adjacent dividing teeth is usually large. Otherwise, if the spacing between the dividing teeth is too small, the glass sheets will be scratched by the dividing teeth during placement due to close contact. Furthermore, the large spacing between adjacent dividing teeth allows the glass sheets some room to move. During transportation and within the tempering furnace, airflow or mechanical vibration can easily cause the glass sheets to shake, resulting in contact between adjacent sheets, causing surface scratches and affecting product quality. Traditional solutions to address this include increasing the spacing between the stacked sheets or improving the transportation method, but these methods are not very effective. For example, increasing the spacing between the stacked sheets reduces the number of glass sheets that can be placed, affecting production efficiency; improving the transportation method increases production costs. Utility Model Content

[0004] The present invention aims to provide a device for preventing overlapping sheet scratches on the pressure strip, so as to provide a simple device that effectively prevents overlapping sheet scratches and is easy to install.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for preventing stacked sheets from scratching the pressure strip includes two crossbeams, the distance between the two crossbeams being greater than the sum of the widths of multiple stacked sheets, an operating beam and multiple sleeves evenly spaced between the two crossbeams are fixedly connected, a gap is left between the operating beam and the multiple sleeves, and the sleeves are used to press down the tops of the multiple stacked sheets.

[0007] The working principle and beneficial effects of this utility model:

[0008] Multiple glass plates are stacked on a placement rack to form a stack. Then, the pressure strip device is placed on the stack by holding the operating beam. The stacks are positioned between the crossbeams on both sides. The sleeve presses against the top of the stacks, utilizing the weight of the operating beam, sleeve, and crossbeams to directly press down on the top of the stacks, thus fixing them downwards and preventing them from shaking due to airflow or mechanical vibration during transportation or in the tempering furnace. This effectively prevents scratches between the stacks. Furthermore, the contact area between the sleeve and the stacks is small to reduce friction.

[0009] This application uses its own weight to directly press the top of the glass, and a high-temperature resistant sleeve is fitted on the surface to reduce friction. This effectively prevents scratches on the stacked glass, simplifies the operation process, saves labor costs, is compatible with existing tempering furnace racks, does not require modification of existing tempering furnace racks, and is compatible with mainstream production lines, thus having significant economic benefits and practical value.

[0010] Furthermore, the crossbeam is fixed with support blocks, and the operating beam is fixed between the support blocks on both sides. The support blocks widen the distance between the operating beam and the sleeve to prevent accidental contact with the stacked plates.

[0011] Furthermore, the number of sleeves is three. The three sleeves are used to simultaneously compress the three stacked sheets.

[0012] Furthermore, the sleeve is made of high-temperature resistant material. This high-temperature sleeve is suitable for the tempering furnace environment, extending the service life of the equipment.

[0013] Furthermore, the number of operating beams is two. The two operating beams facilitate handheld operation. Attached Figure Description

[0017] Figure 4 This is a schematic diagram of the structure being fed into the tempering furnace. Detailed Implementation

[0018] The following detailed description illustrates the specific implementation method:

[0019] The reference numerals in the accompanying drawings include: operating beam 1, sleeve 2, crossbeam 3, stacked plate 4, placement rack 5, and partition tooth 6.

[0020] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0021] Example: A pressure strip device to prevent scratches from overlapping sheets, such as Figure 1 As shown, the device includes two crossbeams 3 and an operating beam 1. The distance between the two crossbeams 3 is greater than the sum of the widths of the stacked plates 4. Three sleeves 2, made of high-temperature resistant material, are evenly spaced and fixed between the two crossbeams 3. Support blocks are fixed to the crossbeams 3, and the operating beam 1 is fixed between the support blocks on both sides. The distance between the operating beam 1 and the sleeves 2 is widened by the support blocks to prevent accidental contact with the stacked plates 4.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, multiple glass sheets are stacked on a placement rack 5. Multiple separating teeth 6 on the placement rack 5 separate the glass sheets into stacks 4. Then, the pressure strip device is placed on three stacks 4 by holding the operating beam 1. The three stacks 4 are located between the two side beams 3. The sleeve 2 presses against the top of the three stacks 4. The weight of the operating beam 1, sleeve 2, and beams 3 directly presses against the top of the three stacks 4, and in conjunction with the separating teeth 6, presses the three stacks 4 downwards, preventing displacement caused by airflow or mechanical vibration during transportation and tempering furnace. This effectively prevents scratches between the glass sheets. Furthermore, the contact area between the sleeve 2 and the stacks 4 is small to reduce friction.

[0023] This application uses its own weight to directly press the top of the glass, and a high-temperature resistant sleeve 2 is fitted on the surface to reduce friction, which can effectively prevent the glass from being scratched, simplify the operation process, save labor costs, adapt to existing tempering furnace racks, eliminate the need to modify existing tempering furnace racks, and adapt to mainstream production lines, thus having significant economic benefits and practical value.
