Description

Technical Field

[0001] This utility model belongs to the field of display glass and relates to an edge grinding and positioning device for display glass. Background Technology

[0002] Display glass refers to the glass substrate used in various display devices. It is one of the core components of the display panel, and its surface flatness, light transmittance, and edge quality directly affect the display effect, lifespan, and user experience of the display device. Edge grinding and positioning involves precisely positioning the glass and grinding its edges. On the one hand, this removes defects such as burrs and chipped edges from the glass after cutting, preventing glass breakage and injuries to personnel due to sharp edges during subsequent assembly or use, or affecting the bonding accuracy with other components due to uneven edges. On the other hand, precise positioning ensures the consistency of glass edge grinding, meeting the assembly requirements of the display device.

[0003] Taking the prior art with publication number CN212578378U and titled "A Glass Edge Grinding Positioning Device" as an example, this device mainly relies on a conveying mechanism to transport the glass to the edge grinding mechanism for grinding both sides of the glass. In terms of positioning, it is only suitable for rectangular glass, achieving initial positioning of the rectangular glass through the fixed track and limiting components of the conveying mechanism. However, for irregularly shaped glass (such as triangular, elliptical, etc.), this device cannot achieve effective positioning. When dealing with rectangular glass of different sizes, its positioning adjustment flexibility is poor, requiring manual adjustment of the limiting component position, which is not only time-consuming and labor-intensive, but also greatly affected by human factors in positioning accuracy. The aforementioned glass edging positioning device has the following problems: First, the positioning accuracy is insufficient. It often uses single-direction clamping or manual assisted positioning, which can easily cause the glass to shift during the grinding process, affecting the flatness and dimensional accuracy of the edge grinding. Second, the adsorption and clamping are not well coordinated. Some devices rely solely on adsorption or clamping to fix the glass. Uneven adsorption force can easily cause the glass to deform under stress, while single clamping can easily generate vibration during grinding, affecting the grinding quality. Utility Model Content

[0004] The technical problems to be solved by this utility model are: first, insufficient positioning accuracy, with most devices using single-direction clamping or manual assisted positioning, which easily leads to glass displacement during polishing, affecting the flatness and dimensional accuracy of the edge polishing; second, poor coordination between adsorption and clamping, with some devices relying solely on adsorption or clamping to fix the glass, resulting in uneven adsorption force that easily causes glass deformation, and single clamping that easily generates vibration during polishing, affecting polishing quality. This utility model provides an edge polishing positioning device for display glass, including a base. The upper surface of the base is provided with a positioning unit for clamping and positioning the display glass and maintaining its stability with single-sided clamping. The outer surface of the base is provided with an adsorption unit for achieving uniform clamping during the polishing of the display glass. The positioning unit includes two electric push rods, namely electric push rod 2 and electric push rod 3. Two electric push rods 2 are provided and are symmetrically arranged on the upper surface of the base. Extension platforms are welded and installed on both sides of the base. Two electric push rods 3 are provided and are respectively fixedly installed on the upper surface of the two extension platforms. The working end of the electric push rod 2 is provided with a push plate 2 for lateral clamping and positioning of the display glass. The working end of the electric push rod 3 is provided with a push plate 1 for longitudinal clamping and positioning.

[0005] A pressure sensor is installed at the connection between the working end of the electric push rod and one side surface of the push plate, and a clamping groove is provided on the other side surface of the push plate.

[0006] A pressure sensor is installed at the connection between the three working ends of the electric push rod and one side surface of the push plate. Multiple rollers are rotatably mounted on the outer surface of the push plate, and the outer surfaces of the multiple rollers are all covered with rubber sleeves.

[0007] The adsorption unit of this utility model includes a suction nozzle, and a storage groove is provided on the upper surface of the base. The suction nozzle is slidably installed inside the storage groove. Multiple suction nozzles are provided, and the multiple suction nozzles are fixedly installed with the air holes on the surface of the suction cup.

[0008] The base of this utility model is equipped with an electric push rod four on its lower surface. The working end of the electric push rod four is located inside the storage groove and is fixedly connected to the lower surface of the suction cup. Telescopic rods are installed on the surfaces of the four corners of the storage groove, and the working ends of the telescopic rods are fixedly connected to the lower surface of the suction cup.

[0009] The base of this utility model has brackets symmetrically installed on its upper surface, and electric push rods are fixedly installed on the lower surfaces of the two brackets. The working ends of the two electric push rods are equipped with a slide block. A servo motor is fixedly installed on one side surface of the slide block. The working end of the servo motor is set in a groove opened on the outer surface of the slide block and threadedly connected to a slider that is slidably installed in the groove opened on the outer surface of the slide block. A slide table is fixedly installed on the lower surface of the slider.

[0010] The outer surface of the sliding end of the present invention is provided with a grinding device, and the outer surface of the sliding end is provided with a spray pipe.

[0011] First, the display glass is placed on the surface of multiple suction nozzles on the suction cup. The electric push rod four works to lift the suction cup away from the storage slot, thereby lifting the display glass. When the display glass is lifted and is at the same height as the rubber sleeve in push plate one and the clamping groove opened on the surface of push plate two, the electric push rod four stops working. The two electric push rods work to support the display glass by pushing the push plate one. Then, the electric push rod four moves the suction cup downward to detach the suction nozzle from the display glass. At this time, the two electric push rods three are used to center the display glass vertically. After the longitudinal centering is completed, the two electric push rods 2 work, pushing the push plate 2 to work, while the clamping grooves hold the two sides of the display glass, pushing the display glass, and the display glass slides on the roller, thus completing the lateral centering. This ensures that the positioning is completed before fixing, thereby improving the quality of polishing. After positioning is completed, the electric push rod pushes the suction cup to rise, thereby pressing the nozzle tightly against the suction cup. The suction cup then holds the display glass in place, ensuring even force distribution during grinding and fixing. When the grinding device grinds the longitudinal edge of the display glass, the electric push rod two will drive the push plate two to disengage from the clamping of the display glass, while the push plate one will clamp the transverse edge. When the transverse edge of the display glass is ground, the electric push rod three will drive the push plate one to disengage from the clamping of the display glass, while the push plate two will clamp the longitudinal edge. This prevents the suction nozzle from exerting a flexible force between the two when adsorbing the display glass, which would affect the quality of the grinding process.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a synergistic design of a positioning unit and an adsorption unit: The positioning unit adopts a two-way positioning structure with horizontal (electric push rod 2 + push plate 2) and vertical (electric push rod 3 + push plate 1). With the clamping groove of push plate 2 and the roller design of push plate 1, the glass can be quickly centered and positioned. Pressure sensor 1 and pressure sensor 2 can monitor the clamping force in real time and provide feedback for adjustment, effectively avoiding glass breakage caused by excessive clamping. The rubber sleeve on the outside of the roller further prevents surface scratches from occurring during the glass sliding process, ensuring the quality of the glass surface. Meanwhile, the electric push rods drive the suction cups and nozzles to lift and lower, which can detach from the glass during the positioning stage to avoid interference. After positioning, the glass is evenly adsorbed by multiple nozzles to ensure stable force on the glass during polishing. When polishing different sides, the electric push rods two and three can switch between single-sided clamping to avoid the clamping force on the non-polished side affecting the polishing accuracy.

[0015] like Figures 1 to 5 As shown, an edge grinding and positioning device for display glass includes a base 1. The upper surface of the base 1 is provided with a positioning unit 10 for clamping and positioning the display glass and keeping the display glass stable by clamping it on one side. The outer surface of the base 1 is provided with an adsorption unit 11 for uniform clamping during the grinding of the display glass. The positioning unit 10 includes two electric push rods 101 and 102. There are two electric push rods 101, which are symmetrically arranged on the upper surface of the base 1. Extension platforms 110 are welded and installed on both sides of the base 1. There are two electric push rods 102, which are respectively fixedly installed on the upper surface of the two extension platforms 110. The working end of the electric push rod 101 is provided with a push plate 107 for lateral clamping and positioning of the display glass. The working end of the electric push rod 102 is provided with a push plate 103 for longitudinal clamping and positioning.

[0016] In Example 1, both electric push rod 2 101 and electric push rod 3 102 are powered by an external power source. When electric push rod 2 101 operates, push plate 2 107 clamps the longitudinal edge of the display glass, while when electric push rod 3 102 operates, push plate 1 103 clamps the transverse edge of the display glass.

[0017] like Figure 2 and Figure 5 As shown, a pressure sensor 108 is installed at the connection between the working end of the electric push rod 101 and one side surface of the push plate 107, and a clamping groove 109 is provided on the other side surface of the push plate 107.

[0018] In Example 2, pressure sensor 2 108 is electrically connected to electric push rod 2 101. When electric push rod 2 101 causes push plate 2 107 to clamp the display glass, it can provide feedback force to prevent excessive clamping force from crushing the display glass.

[0019] like Figure 4 As shown, a pressure sensor 104 is installed at the connection between the working end of the electric push rod 102 and one side surface of the push plate 103. Multiple rollers 105 are rotatably mounted on the outer surface of the push plate 103, and the outer surfaces of the multiple rollers 105 are all covered with rubber sleeves 106.

[0020] In Example 3, pressure sensor 104 is electrically connected to electric push rod 102. When electric push rod 102 causes push plate 103 to clamp the display glass, it can provide feedback force to prevent the display glass from being crushed due to excessive clamping force. The rubber sleeve 106 can prevent scratches from being generated on the surface of the roller 105 when the display glass rolls on the surface.

[0021] like Figure 3 As shown, the adsorption unit 11 includes a suction nozzle 116. A storage groove 111 is provided on the upper surface of the base 1. The suction nozzle 116 is slidably installed inside the storage groove 111. Multiple suction nozzles 116 are provided, and multiple suction nozzles 116 are fixedly installed with the air holes on the surface of the suction cup 115.

[0022] In Example 4, the suction cup 115 is powered by an external power source. The suction cup 115 cooperates with the suction nozzle 116 to adsorb the display glass without damaging the surface of the display glass.

[0023] like Figure 3 As shown, an electric push rod 112 is installed on the lower surface of the base 1. The working end of the electric push rod 112 is located inside the storage slot 111 and is fixedly connected to the lower surface of the suction cup 115. Telescopic rods 113 are installed on the surfaces of the four corners of the storage slot 111, and the working ends of the telescopic rods 113 are fixedly connected to the lower surface of the suction cup 115.

[0024] In Example 5, the electric push rod 112 is powered by an external power source and can raise and lower the suction cup 115. The telescopic rod 113 ensures the stability of the suction cup 115 during raising and lowering.

[0025] like Figure 1 As shown, brackets 2 are symmetrically installed on the upper surface of the base 1, and electric push rods 3 are fixedly installed on the lower surface of both brackets 2. A slide block 4 is installed at the working end of each of the two electric push rods 3. A servo motor 5 is fixedly installed on one side surface of the slide block 4. The working end of the servo motor 5 is set in a groove opened on the outer surface of the slide block 4 and threadedly connected to a slider 6 that is slidably installed in the groove opened on the outer surface of the slide block 4. A slide table 7 is fixedly installed on the lower surface of the slider 6.

[0026] In Example 6, the electric push rod 3 can indirectly drive the grinding device 9 to move up and down, the servo motor 5 and the slide 4 can drive the grinding device 9 to move laterally, and the slide table 7 can drive the grinding device 9 to move longitudinally. All of them are powered by an external power source.

[0027] like Figure 1 As shown, a polishing device 9 is provided on the outer surface of the moving end of the slide table 7, and a nozzle 8 is provided on the outer surface of the moving end of the slide table 7.

[0028] Example 7: The nozzle 8 is connected to an external water source, and water is sprayed during polishing to achieve a cooling effect.

[0029] Working principle: First, the display glass is placed on the surface of multiple suction nozzles 116 on the suction cup 115. The electric push rod 112 works to lift the suction cup 115 away from the storage groove 111, thereby lifting the display glass. When the display glass is lifted and is at the same height as the rubber sleeve 106 in the push plate 103 and the clamping groove 109 on the surface of the push plate 2 107, the electric push rod 112 stops working. Two electric push rods 102 work to support the display glass by pushing push plate 103. Then, electric push rod 112 drives suction cup 115 to move downward and detach suction nozzle 116 from the display glass. At this time, the two electric push rods 102 centrally position the display glass vertically. After the longitudinal centering is completed, the two electric push rods 101 work to push the push plate 107 to work, and the clamping groove 109 clamps the two sides of the display glass and pushes the display glass. The display glass slides on the roller 105, thus completing the lateral centering. This ensures that the positioning is completed before fixing, thereby improving the quality of polishing. After positioning is completed, the electric push rod 112 pushes the suction cup 115 to rise, thereby pressing the suction nozzle 116 tightly against the suction cup. The suction cup 115 then holds the display glass in place, ensuring even force distribution during grinding and fixing. When the polishing device 9 polishes the longitudinal edge of the display glass, the electric push rod 2 101 will drive the push plate 2 107 to disengage from the clamping of the display glass, while the push plate 1 103 will clamp the transverse edge. When polishing the transverse edge of the display glass, the electric push rod 3 102 will drive the push plate 1 103 to disengage from the clamping of the display glass, while the push plate 2 107 will clamp the longitudinal edge. This can prevent the suction nozzle 116 from having a flexible force between the two when adsorbing the display glass, thus affecting the quality of polishing.
