Description

Technical Field

[0001] This utility model relates to the field of ultra-thin UTG glass production technology, specifically a vacuum adsorption device for ultra-thin UTG glass. Background Technology

[0002] Ultra-thin UTG glass is a flexible glass material with a thickness of less than 100 micrometers (about 0.1 millimeters). Due to its ultra-thin and flexible properties, UTG glass is widely used in foldable screen phones, flexible displays and other fields.

[0003] The following problems exist in the production and handling of ultra-thin UTG glass: Since the thickness of UTG glass is usually 30~100μm, the suction force of traditional suction cups is uneven, which can easily lead to breakage of UTG glass; ordinary rubber suction cups have poor sealing performance for ultra-thin glass and are prone to air leakage and detachment; surface contamination: the suction cup material may have residual particles that scratch the glass surface; existing suction cups are mostly designed for ordinary glass and cannot meet the high-precision operation requirements of UTG glass. Therefore, we propose a vacuum adsorption device for ultra-thin UTG glass. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum adsorption device for ultra-thin UTG glass, in order to solve the problems mentioned in the background art, such as the glass being fragile and easily cracked, adsorption failure, and surface contamination of the adsorption cup when adsorbing ultra-thin UTG glass.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum adsorption device for ultra-thin UTG glass, comprising a device base plate, a device frame fixed to the top of the device base plate, and a glass support platform installed on one side of the bottom of the device frame. A cylinder is installed on the outer wall of the device frame above the glass support platform. A multi-stage vacuum control structure is provided below the cylinder. The multi-stage vacuum control structure includes a primary vacuum pump and a secondary precision pressure regulating valve. The primary vacuum pump is located below the cylinder and is fixedly connected to the output end of the cylinder. The secondary precision pressure regulating valve is located below the cylinder. Below the primary vacuum pump, and with an outlet pipe installed at the top of the secondary precision pressure regulating valve and an inlet pipe installed at the bottom of the secondary precision pressure regulating valve, a vacuum adsorption structure is provided below the multi-stage vacuum control structure. The vacuum adsorption structure includes a vacuum suction cup and a flexible buffer layer. The vacuum suction cup is installed below the secondary precision pressure regulating valve, and the lower surface of the vacuum suction cup is provided with micron-sized adsorption holes. The flexible buffer layer is adhered to the lower surface of the vacuum suction cup with silicone adhesive. An electrostatic elimination structure is provided on one side of the bottom of the vacuum adsorption structure, and the electrostatic elimination structure includes an ion fan and an ion bar.

[0006] Preferably, the micron-sized adsorption pore array is distributed, and the pore diameter of the micron-sized adsorption pores is 50~200μm, and the spacing between the micron-sized adsorption pores is 100~300μm.

[0007] Preferably, the surface array of the flexible buffer layer is provided with micron-sized through holes, and the micron-sized through holes are aligned one-to-one with the micron-sized adsorption pores, and the pore diameter of the micron-sized through holes is the same as that of the micron-sized adsorption pores.

[0008] Preferably, the flexible buffer layer is made of low-hardness silicone with a Shore hardness of 10~30A or aerogel material, and the shape and size of the flexible buffer layer are completely consistent with the lower surface of the vacuum suction cup.

[0009] Preferably, the outlet pipe is connected to the input end of the primary vacuum pump, and the inlet pipe is connected to the vacuum suction cup.

[0010] Preferably, the dynamic adjustment range of the secondary precision pressure regulating valve is 0~-80kPa.

[0011] Preferably, the ion fan is installed on the outer wall of the device frame on one side of the vacuum adsorption structure.

[0012] Preferably, the ion bar is installed at the output end of the ion blower, and one end of the ion bar extends to one side of the bottom of the vacuum suction cup.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The cylinder drives the multi-stage vacuum control structure and vacuum adsorption structure to move downward, so that the vacuum suction cup is gently placed on the UTG glass surface. The flexible buffer layer automatically adheres. The flexible buffer layer can adhere to the UTG glass in a bent state, such as a folding screen, to avoid the situation of "local vacuum leakage and unstable suction". The surface of the vacuum suction cup is covered with several micron-sized adsorption holes to reduce local stress and prevent UTG glass from breaking, and a flexible buffer layer is used to provide cushioning. The first-stage vacuum pump rapidly evacuates air within one or two seconds, allowing the glass to instantly adhere to the vacuum adsorption structure for rapid positioning. Then, the second-stage precision pressure regulating valve immediately intervenes to dynamically adjust the adsorption force and adjust the negative pressure according to the glass thickness to prevent over-adsorption and glass deformation. By activating the static elimination structure, the ion fan uses ion bars to remove static electricity and blow away dust from the vacuum suction cup and glass, ensuring that there are no residual particles on the surface of the glass and suction cup, making it clean and undisturbed.

Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-6 An embodiment of this utility model is provided: a vacuum adsorption device for ultra-thin UTG glass, including a device base plate 1, a device frame 2 fixed to the top of the device base plate 1, a glass support platform 3 installed on one side of the bottom of the device frame 2, and a cylinder 5 installed on the outer wall of the device frame 2 above the glass support platform 3. A multi-stage vacuum control structure 6 is provided below the cylinder 5. The multi-stage vacuum control structure 6 includes a first-stage vacuum pump 7 and a second-stage precision pressure regulating valve 12. The first-stage vacuum pump 7 is located below the cylinder 5 and is fixedly connected to the output end of the cylinder 5. The second-stage precision pressure regulating valve 12 is located below the first-stage vacuum pump 7, and an outlet pipe 11 is installed at the top of the second-stage precision pressure regulating valve 12, and an inlet pipe 13 is installed at the bottom of the second-stage precision pressure regulating valve 12. Specifically, the first-stage vacuum pump 7 of the multi-stage vacuum control structure 6 rapidly evacuates air within one or two seconds, allowing the glass to instantly adhere to the vacuum adsorption structure 8 for rapid positioning. Immediately afterwards, the second-stage precision pressure regulating valve 12 intervenes to dynamically adjust the adsorption force and adjust the negative pressure according to the glass thickness, such as -30kPa for 30μm glass, to prevent over-adsorption and glass deformation. During the adsorption process, the surface of the vacuum suction cup 9 is distributed with several micron-sized adsorption holes 14 to reduce local stress and prevent UTG glass from breaking. It also works with the flexible buffer layer 10 to provide buffering, achieving rapid, stable, damage-free, and dust-free adsorption, perfectly adapting to the processing requirements of ultra-thin UTG glass. After the transport is completed, first release the secondary precision pressure regulating valve 12, and then release the primary vacuum pump 7 to avoid sudden pressure loss that could cause the glass to shake. Below the multi-stage vacuum control structure 6 is a vacuum adsorption structure 8, which includes a vacuum suction cup 9 and a flexible buffer layer 10. The vacuum suction cup 9 is installed below the secondary precision pressure regulating valve 12. The lower surface of the vacuum suction cup 9 is provided with micron-level adsorption holes 14. The flexible buffer layer 10 is adhered to the lower surface of the vacuum suction cup 9 with silicone adhesive. Specifically, the UTG glass is placed flat on the glass support platform 3. The cylinder 5 drives the multi-stage vacuum control structure 6 and the vacuum adsorption structure 8 to move down, so that the vacuum suction cup 9 is gently placed on the surface of the UTG glass. The flexible buffer layer 10 automatically adheres. The flexible buffer layer 10 can adhere to the UTG glass in a bent state, such as a folding screen, to avoid the situation of "local vacuum leakage and unstable suction". A static electricity elimination structure 4 is provided on one side of the bottom of the vacuum adsorption structure 8. The static electricity elimination structure 4 includes an ion fan 16 and an ion fan bar 17. The array of micron-sized adsorption pores 14 is distributed, with the pore diameter of the micron-sized adsorption pores 14 being 50~200μm and the spacing between the micron-sized adsorption pores 14 being 100~300μm; ensuring that the adsorption coverage of each pore does not overlap. The surface of the flexible buffer layer 10 is arrayed with micron-sized through holes 15, and the micron-sized through holes 15 are aligned one-to-one with the micron-sized adsorption holes 14, and the pore size of the micron-sized through holes 15 is the same as that of the micron-sized adsorption holes 14. The flexible buffer layer 10 is made of low-hardness silicone with a Shore hardness of 10~30A or aerogel material, and the shape and size of the flexible buffer layer 10 are completely consistent with the lower surface of the vacuum suction cup 9. By pre-drilling micron-sized through holes 15 on the flexible buffer layer 10 that are aligned with the micron-sized adsorption holes 14, and ensuring that the adsorption force can pass through the flexible buffer layer 10 and adhere to the glass without being blocked, and by separating the glass from the metal suction cup with the soft material of the flexible buffer layer 10, the risk of "hard contact scratching the glass" is completely eliminated. The exhaust pipe 11 is connected to the input end of the first-stage vacuum pump 7, and the intake pipe 13 is connected to the vacuum suction cup 9; The dynamic adjustment range of the secondary precision pressure regulating valve 12 is 0~-80kPa; The ion fan 16 is installed on the outer wall of the device frame 2 on one side of the vacuum adsorption structure 8; Ionizing air bar 17 is installed at the output end of ionizing air blower 16, and one end of ionizing air bar 17 extends to one side of the bottom end of vacuum suction cup 9. Furthermore, the static elimination structure 4 is activated, so that the ion fan 16 removes static electricity and blows away dust from the vacuum suction cup 9 and the glass through the ion fan bar 17, ensuring that there are no residual particles on the surface of the glass and suction cup, and that they are clean and free from interference.

[0019] In this embodiment, the following steps are taken during use: First, the UTG glass is placed flat on the glass support platform 3. The cylinder 5 drives the multi-stage vacuum control structure 6 and the vacuum adsorption structure 8 to move downwards, allowing the vacuum suction cup 9 to be gently placed on the surface of the UTG glass. The flexible buffer layer 10 automatically adheres, and the flexible buffer layer 10 can adhere to the UTG glass in a bent state, such as a folding screen, avoiding the situation of "partial vacuum leakage and unstable suction". Second, the static elimination structure 4 is activated, so that the ion fan 16 removes static electricity and blows away dust from the vacuum suction cup 9 and the glass through the ion fan bar 17, ensuring that there are no residual particles on the surface of the glass and the suction cup, and that it is clean and undisturbed. The first-stage vacuum pump 7 of the multi-stage vacuum control structure 6 rapidly evacuates air within one or two seconds, allowing the glass to instantly adhere to the vacuum adsorption structure 8 for rapid positioning. Immediately afterwards, the second-stage precision pressure regulating valve 12 intervenes to dynamically adjust the adsorption force, adjusting the negative pressure according to the glass thickness, such as -30kPa for 30μm glass, to prevent over-adsorption and glass deformation. During the adsorption process, the surface of the vacuum suction cup 9 is distributed with several micron-sized adsorption holes 14 to reduce local stress and prevent UTG glass from breaking. It also works in conjunction with the flexible buffer layer 10 to provide cushioning, achieving rapid, stable, damage-free, and dust-free adsorption, perfectly adapting to the processing requirements of ultra-thin UTG glass. Finally, after the handling is completed, the second-stage precision pressure regulating valve 12 is released first, and then the first-stage vacuum pump 7 is deactivated to avoid sudden pressure loss that could cause the glass to shake.

[0020] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
