Description

Technical Field

[0001] The invention relates to the field of ultra-thin glass processing and manufacturing, and in particular to an ultra-thin glass lamination device and a lamination method. Background Art

[0002] Ultra thin glass (UTG) is mainly used for glass cover plates of folding mobile phones. It is bendable and has light crease characteristics. It is widely demanded in new folding mobile phone products. The general thickness of ultra thin glass in the industry is 0.12-0.15mm. However, due to the thin structure of ultra thin glass, it is easy to produce tip stress concentration effect at the edge position, which may cause glass breakage, so the production yield of UTG is low. In order to improve the structural strength of UTG, the edges of the UTG products need to be strengthened, including physical polishing and strengthening through grinding and chemical strengthening through etching liquid, so as to reduce micro cracks at the edge position, improve the overall strength performance of the product, and meet the strength requirements of folding mobile phone glass cover plates. At the same time, because the UTG structure is too thin, traditional glass processing methods cannot directly process and grind a single piece of UTG.

[0003] At present, UTG mainly uses stacking to process the overall edge of multiple pieces of UTG. However, the traditional stacking solution is prone to problems such as empty glue and uneven glue layer thickness in the "glue dispensing-stacking-pressure holding" process, which will cause product breakage in the subsequent CNC edge processing process, resulting in low product processing yield. At the same time, the traditional stacking processing solution urgently needs to be improved to improve processing efficiency. Summary of the invention

During the lamination process, for ultra-thin glass (thickness is 0.01mm-0.1mm) that is thinner than general ultra-thin glass, considering that thinner ultra-thin glass is lighter and easier to slide, there will be a certain amount of sliding between ultra-thin glasses after each dispensing of glue, which is more prone to misalignment during the lamination process and more fragile during subsequent edge grinding. The present application achieves more accurate alignment and more uniform dispensing between adjacent two glasses, which is more accurate than the alignment method in the prior art, achieves high-precision matching, improves the alignment accuracy of the lamination, and ensures that each layer of glass is not offset after alignment, reducing movement deviation. Thereby, accurate UTG stacking alignment and uniform pressure holding and lamination are achieved, thereby achieving the goal of refining the edge flatness of the product, improving the edge strength, and preventing the problem of easy breakage during lamination. In addition, due to more precise alignment, the processing allowance of CNC edge grinding after lamination and pressure holding can be reduced, thereby reducing the undesirable problems such as edge collapse and shattering of ultra-thin glass during CNC edge grinding in the prior art, thereby improving the product yield. Since the position is automatically corrected after each lamination, the glue dispensing is more uniform, the thickness is more uniform, and there are no bubbles inside. In this way, for ultra-thin glass, the problem of ultra-thin glass being fragile when the overall pressure is held after stacking multiple sheets is solved, and the etching solution may corrode the large surface of the glass during subsequent chemical strengthening. It not only improves the yield, but also ensures that the overall pressure holding can be achieved. In addition, since the pressure holding is performed again after multiple layers are stacked, the processing efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Embodiment 1

[0049] See also Figure 1 An embodiment of the present application provides an ultra-thin glass lamination device 100 for laminating ultra-thin glass for subsequent processing. The ultra-thin glass lamination device 100 can increase the number of layers stacked when laminating multiple ultra-thin glass sheets, improve efficiency, ensure the accuracy of the stacking position, the uniformity of the glue layer thickness, and the yield and stability of subsequent processing. Therefore, after the subsequent edge CNC processing, the purpose of refining the edge flatness of the product and improving the overall strength of the product is achieved.

[0050] The ultra-thin glass lamination device 100 includes a feeding mechanism 10, a transfer mechanism 20, a detection mechanism 30, a stacking mechanism 40, a glue dispensing mechanism 50, a pressure-maintaining mechanism 60 and a feeding mechanism 70. The feeding mechanism 10, the transfer mechanism 20, the detection mechanism 30, the stacking mechanism 40, the glue dispensing mechanism 50, the pressure-maintaining mechanism 60 and the feeding mechanism 70 are respectively arranged on a frame 101. The feeding mechanism 10, the detection mechanism 30 and the stacking mechanism 40 are arranged in sequence along the transfer direction of the transfer mechanism 20. The feeding mechanism 10 is used to place the glass materials to be stacked. The transfer mechanism 20 and the stacking mechanism 40 are controlled and connected with the detection mechanism 30. The transfer mechanism 20 is used to grab the glass materials on the feeding mechanism 10 one by one and transfer them to the stacking mechanism 40. The detection mechanism 30 is used to detect the glass materials grabbed by the transfer mechanism 20 to determine the position parameters of the grabbed glass materials, and the position parameters mainly refer to the coordinate positions of the four sides of the loading product. The stacking mechanism 40 is used to adjust the position according to the product characteristics detected by the detection mechanism 30, so that the transfer mechanism 20 can place the grabbed glass materials on the stacking mechanism 40 accurately in sequence. The glue dispensing mechanism 50 and the pressure holding mechanism 60 are arranged close to the stacking mechanism 40. The glue dispensing mechanism 50 is used to perform glue dispensing on the glass materials placed on the stacking mechanism 40 after the transfer mechanism 20 places the glass materials on the stacking mechanism 40. The pressure holding mechanism 60 is used to hold the pressure on the stacked glass materials carried on the stacking mechanism 40 to complete the lamination. The unloading mechanism 70 is used to unload the glass materials on the stacking mechanism 40 after the pressure holding is completed.

[0051] Among them, see Figure 5The stacking mechanism 40 includes an x-axis moving assembly 41, a y-axis moving assembly 42, a z-axis rotating assembly 43 and a carrying fixture 44. The y-axis moving assembly 42 is slidably mounted on the x-axis moving assembly 41. The z-axis rotating assembly 43 is slidably mounted on the y-axis moving assembly 42. The carrying fixture 44 is mounted on the z-axis rotating assembly 43. The detection mechanism 30 and the stacking mechanism 40 are respectively arranged on the upstream and downstream sides of the transfer mechanism 20. The glass material is transferred from the detection mechanism 30 to the stacking mechanism 40 through the transfer mechanism 20. The position parameters of the glass material to be stacked are obtained through the detection mechanism 30. The position of the stacked glass material on the supporting fixture 44 is obtained through the stacking mechanism 40. The stacking mechanism 40 controls the supporting fixture 44 to rotate around the z-axis according to the position of the stacked glass material and the position parameters of the glass material to be stacked, so that the orientation of the stacked glass material on the supporting fixture 44 is consistent with that of the glass material to be stacked. The glass material to be stacked is transferred to the top of the stacked glass material through the transfer mechanism 20 and the y-axis moving component 42; after each piece of glass material is stacked, glue is dispensed on the top of the glass material through the glue dispensing mechanism 50; after the multiple layers of glass material are stacked in place, the pressure-maintaining mechanism 60 is used to maintain the overall pressure. Thereby, the automation of the entire process of glass material stacking is realized, and the positions of the glass materials to be stacked and the stacked glass materials are obtained through each stacking, and the transfer mechanism 20 is controlled to perform the x-axis and y-axis moving components 42 to perform the y-axis and z-axis rotating components 43 to adjust the positions around the z-axis, thereby ensuring that the glass materials to be stacked and the stacked glass materials are in place, thereby improving the alignment accuracy.

[0052] Compared with general ultra-thin glass, ultra-thin glass (thickness is 0.01mm-0.1mm) is thinner and lighter in weight. This application takes into account the problem that ultra-thin glass is more likely to slide after each glue application, thereby achieving more precise alignment between adjacent glasses and making the glue between adjacent glasses more uniform.

[0053] Due to more precise alignment, the processing allowance of CNC edge grinding after lamination and pressure holding can be reduced, thereby reducing the edge collapse and breakage of ultra-thin glass during CNC edge grinding in the existing technology, thereby improving product yield;

[0054] Since the glue is more uniform (the position is automatically corrected after each stacking, the thickness is more uniform, and there are no bubbles inside), this solves the problem of ultra-thin glass being fragile when the overall pressure is maintained after stacking multiple sheets. It also reduces the possibility of etching liquid corroding the large surface of the glass during subsequent chemical strengthening, which not only improves the yield but also ensures that the overall pressure can be maintained. Since the pressure is maintained again after multiple layers are stacked, the processing efficiency is improved.

[0055] For details, please also refer to Figure 2The loading mechanism 10 includes a first loading platform 11 and a first loading moving assembly 12. The first loading platform 11 is used to place the glass material to be loaded. The first loading platform 11 is slidably arranged on the frame 101 and is located on the upstream side of the transfer mechanism 20. The first loading moving assembly 12 is arranged on the frame 101, and its driving end is connected to the first loading platform 11. The first loading moving assembly 12 is used to drive the first loading platform 11 to slide on the frame 101.

[0056] For details, please refer to Figure 1 , establish a Cartesian coordinate system, define the x-axis as the direction in which the transfer mechanism 20 grabs the glass material and moves, and the direction in which the unloading mechanism 70 unloads the material; define the y-axis as the direction in which the first loading moving component 12 drives the first loading platform 11 to slide on the frame 101; define the z-axis as the vertical height direction; wherein the x-axis, y-axis and z-axis are perpendicular to each other. It can be understood that the above definitions are only for the purpose of facilitating the understanding of the relative positional relationship of each component, and should not be construed as a limitation to the present application.

[0057] The feeding mechanism 10 further includes a first slide rail 13 and a stopper 14. The first slide rail 13 is disposed on the frame 101 and extends along the y-axis direction. The first feeding platform 11 is slidably disposed on the first slide rail 13 through the first feeding moving assembly 12. The stopper 14 is disposed on the first feeding moving assembly 12, and the stopper 14 is used to limit the moving distance of the first feeding platform 11 on the first slide rail 13.

[0058] In some embodiments, the feeding mechanism 10 further includes a second feeding platform 15 and a second feeding moving assembly 16. The second feeding platform 15 is also slidably disposed on the first slide rail 13 through the second feeding moving assembly 16. The second feeding moving assembly 16 is disposed on the frame 101, and a driving end thereof is connected to the second feeding platform 15. The second feeding moving assembly 16 is used to drive the second feeding platform 15 to slide on the frame 101.

[0059] The first loading platform 11 and the second loading platform 15 are used to place different glass materials, respectively. When laminating ultra-thin glass, if thick glass is used as protective glass at the top and bottom of the stack, it is more appropriate to fix the stacked stack as a whole, which is more conducive to improving the yield of subsequent processing. Therefore, two loading platforms are used to load thick glass and ultra-thin glass materials respectively, which improves the efficiency of the operation and the yield of processing. Of course, one loading platform can also be used, and thick glass, multiple ultra-thin glasses and another thick glass can be stacked on it, which can also improve the processing yield; it can also be that two loading platforms load ultra-thin glass materials at the same time, but it is not limited to this.

[0060] It can be understood that two groups of the limit members 14 are provided, and the two groups of limit members 14 are respectively provided on the first loading moving assembly 12 and the second loading moving assembly 16 to limit the moving distances of the first loading platform 11 and the second loading platform 15 respectively.

[0061] In some embodiments, the limiting member 14 is a limiting magnet, the first loading moving component 12 and the second loading moving component 16 are cylinders respectively, and each group of limiting magnets is respectively arranged at both ends of the corresponding cylinders, which are used to adsorb the first loading platform 11 and the second loading platform 15 to achieve the positioning of the platform.

[0062] In some embodiments, a switch button is provided next to the first loading platform 11 and the second loading platform 15. After the glass material is manually placed on the platform, the button is pressed and the device starts to automatically stack the glass.

[0063] In some embodiments, the surfaces of the first loading platform 11 and the second loading platform 15 are respectively provided with a plurality of suction holes 111 to adsorb and fix the glass materials placed thereon. The suction holes 111 are controlled by suction pipes to ensure the stability of adsorption during loading.

The first slide rail 13 is docked with the transfer rail 21. The grab assembly 23 is slidably arranged on the transfer rail 21, and the transfer drive assembly 22 is arranged on the transfer rail 21 and is drivingly connected to the grab assembly 23. The transfer drive assembly 22 is used to drive the grab assembly 23 to move along the x-axis on the transfer rail 21. The grab assembly 23 is used to grab the glass material on the feeding mechanism 10 and place the glass material on the stacking mechanism 40.

[0065] In some embodiments, the transfer drive assembly 22 includes a first drive motor 221 and a first lead screw 222. The first lead screw 222 extends along the x-axis direction. The grabbing assembly 23 is arranged on the movable end of the first lead screw 222. The output shaft of the first drive motor 221 is connected to the first lead screw 222. The grabbing assembly 23 is slidably matched with the first lead screw 222. The first lead screw 222 is used to convert the rotation drive of the first drive motor 221 into a linear drive along the x-axis direction, so as to drive the grabbing assembly 23 to move along the x-axis.

[0066] In some embodiments, the first driving motor 221 is a servo motor to accurately control the distance moved along the x-axis. The first lead screw 222 and the transfer guide rail 21 are an integrated structure.

[0067] In some embodiments, the grabbing assembly 23 includes a grabbing driving member 231 and a grabbing member 232. The grabbing driving member 231 is connected to the movable end of the first lead screw 222. The driving end of the grabbing driving member 231 is connected to the grabbing member 232. The grabbing member 232 is used to grab the glass material. The grabbing driving member 231 is used to drive the grabbing member 232 to move along the z-axis, so that the grabbing member 232 grabs the glass material on the feeding mechanism 10 and places the glass material on the stacking mechanism 40.

[0068] In some embodiments, the grabbing driving member 231 is an electric cylinder. The grabbing member 232 is an air suction gripper to control the grabbing force to prevent damage to the glass material.

The y-axis fine-tuning assembly 32 is arranged on the x-axis fine-tuning assembly 33. The CCD camera assembly 31 is used to detect the product characteristics of the glass material grabbed by the grabbing assembly 23. Since the detection mechanism 30 has two groups of CCD camera assemblies 31 and corresponding CCD camera assemblies, but the product characteristics of conventional products include at least the position characteristics of four edges, so when the product is fixed, the CCD camera of each group of CCD camera assemblies 31 needs to capture the position characteristic information of at least two edges at the same time to meet the demand for characteristic information collection. However, due to the different sizes of the feeding products, the CCD camera assembly has a limited adjustment distance in the height direction. In some cases, a single CCD camera assembly cannot simultaneously capture the product and collect the corresponding product edge position information, so it is necessary to fine-tune the position of the CCD camera assembly. The y-axis fine adjustment component 32 is used to fine-tune the position of the CCD camera component 31 along the y-axis direction. The x-axis fine adjustment component 33 is used to fine-tune the position of the CCD camera component 31 along the x-axis direction. For different batches of glass products of different sizes, before lamination begins, the detection mechanism ensures that the imaged product is located in the middle of the image by adjusting the x-axis and y-axis directions.

[0070] Specifically, the CCD camera assembly 31 includes a lens 311 and a light source 312. The lens 311 is disposed on the y-axis fine-tuning assembly 32, and the detection end is upward along the z-axis to photograph the glass material adsorbed by the grabbing assembly 23. The light source 312 is used to fill in the glass material with light to facilitate the photography of the lens 311.

[0071] In some embodiments, the lens 311 can adjust its position in the z-axis direction by itself.

[0072] The y-axis fine-tuning assembly 32 includes a first slide 321, a first slide seat 322, and a first locking member 323. The lens 311 and the light source 312 are both disposed on the first slide 321. The first slide 321 is slidably connected to the first slide seat 322 along the y-axis. The first slide seat 322 is slidably disposed on the x-axis fine-tuning assembly 33. The first locking member 323 is disposed on the first slide seat 322. The first locking member 323 is used to lock and fix the first slide 321 to the first slide seat 322.

[0073] The x-axis fine adjustment assembly 33 includes a second slide 331, a second slide seat 332, and a second locking member 333. The second slide 331 is slidably disposed on the second slide seat 332 along the x-axis. The second slide seat 332 is disposed on the frame 101. The second locking member 333 is disposed on the second slide seat 332. The second locking member 333 is used to lock and fix the second slide 331 on the second slide seat 332. The first slide seat 322 is fixed on the second slide 331.

[0074] In some embodiments, the first locking member 323 is a locking handle, and the second locking member 333 is a locking screw.

[0075] In this embodiment, the first slide 321 extends along the y-axis direction, and the first slide seat 322 is slidably disposed on the first slide 321 along the y-axis direction. The second slide 331 extends along the x-axis direction, and the first slide 321 is slidably disposed on the second slide 331 along the x-axis direction.

[0076] In some embodiments, the CCD camera assembly 31 includes two groups, and the lenses 311 in the two groups of CCD camera assemblies 31 are respectively accurately aligned with a set of diagonal corners of the glass material. By aligning the two corners of the glass material through the light source 312 and adjusting the CCD system, the precise alignment of the glass material can be achieved.

[0077] Specifically, the detection mechanism 30 includes two groups of second slides 332 arranged on the base, and the two groups are arranged side by side. The second slide 331 of any group of the detection mechanism 30 is also slidably arranged on the second slide 332 of the other group of the detection mechanism 30, so that the movement of the second slide 331 is more stable. The lenses 311 of the CCD camera assemblies 31 of the two groups of the detection mechanism 30 are separated from each other along the y-axis direction, so as to align a corresponding set of diagonals on the glass material.

[0078] Please also see Figure 5 , the carrying fixture 44 is used to carry the glass material grabbed by the transfer mechanism 20. The x-axis moving component 41 is used to drive the y-axis moving component 42 to move along the x-axis. The y-axis moving component 42 is used to drive the z-axis rotating component 43 to move along the y-axis. The z-axis rotating component 43 is used to drive the carrying fixture 44 to rotate along the z-axis. The x-axis moving component 41, the y-axis moving component 42 and the z-axis rotating component 43 cooperate with the CCD camera component 31 to realize the movement of the carrying fixture 44 along the x-axis direction, the movement along the y-axis direction and the rotation along the z-axis direction, so that the transfer mechanism 20 can accurately stack the glass material on the carrying fixture 44, and send the stacked glass material to the pressure holding mechanism 60 for pressure holding, and finally send it to the unloading mechanism 70 to unload the glass material after the pressure holding is completed.

[0079] The z-axis rotating assembly 43 compensates for the stacking angle by combining the angle difference between the lines for positioning the two corners of the glass material with the CCD light source and the frame lines of the base of the supporting fixture 44.

[0080] Specifically, the principle of cooperation between the detection mechanism 30 and the stacking mechanism 40 is: the line connecting the corner (the upper left corner in the present invention) of the glass material on the preset supporting fixture 44 after the preset position and its diagonal position is the first line segment, and the midpoint of the first line segment is the first midpoint; the lens 311 shoots the first corner of the glass material corresponding to the preset position and its diagonal position to obtain a first image; the feature points of the two corners in the first image are extracted; the two corners are connected to form a second line segment, and the midpoint of the second line segment is set as the second midpoint; the angle between the first line segment where the first midpoint is located and the second line segment where the second midpoint is located is calculated as α, then the supporting fixture 44 should adjust the angle α accordingly through the z-axis rotation component 43; the distance between the first midpoint and the second midpoint along the X and Y axes is calculated as a and b, then the transfer drive component 22 drives the absorbed glass material to move a along the x-axis direction, and the y-axis moving component 42 drives the supporting fixture 44 to move b along the y-axis direction; finally, the grabbing component 23 puts the glass material on the supporting fixture 44 to complete the alignment and loading of a piece of glass material.

[0081] In some embodiments, the stacking mechanism 40 further includes a centering driving member 45. The centering driving member 45 is disposed on the supporting fixture 44. The centering driving member 45 is used to push the glass material carried on the supporting fixture 44 to correct the position of the glass material on the supporting fixture 44.

[0082] In this embodiment, the center driving member 45 includes two orthogonally arranged ones. The two center driving members 45 are respectively arranged at two sides of the supporting fixture 44 to push the glass material in the x-axis direction and the y-axis direction respectively.

[0083] Specifically in this embodiment, a receiving groove 441 is provided on the top of the supporting fixture 44, a concave flow channel is provided on the edge of the bottom surface of the receiving groove 441, and a center driving member 45 is provided outside the receiving groove 441. The pushing ends of the two center driving members 45 are respectively directed toward the middle of the receiving groove 441 along the x-axis and y-axis directions, so that after the glass material is placed, the glass material is pushed toward the two adjacent inner walls of the receiving groove 441, so that it is located in the middle of the supporting fixture 44, so as to achieve position correction. After the glass material is laminated as a whole, when the pressure is maintained under the pressure maintaining mechanism 60, the excess glue can be discharged through the concave flow channel for centralized collection.

[0084] In some embodiments, the centering driving member 45 is a centering cylinder.

[0085] Specifically, during the process of the transfer mechanism 20 placing the glass material on the carrier jig 44 and the glue dispensing mechanism 50 dispensing the glass material, the offset sliding of the glass material on the carrier jig 44 is corrected. Since the glass material and the glue interact with each other in the above process, the ultra-thin glass may slide on the glue dispensing, thereby having a certain offset. At this time, the centering cylinder is used to correct the centering of the product that may be offset.

[0086] In some embodiments, the x-axis moving assembly 41 is an x-axis driving assembly for driving the supporting fixture 44 to move along the x-axis, and specifically includes an x-axis driving motor 411 and an x-axis screw 412.

[0089] In some embodiments, the stacking mechanism 40 further includes a first guide rail 46, a second guide rail 47 and a rotating seat 48.

The rotating seat 48 is disposed on the driving end of the z-axis rotation assembly 43. The bearing fixture 44 is disposed on the rotating seat 48.

[0090] In some embodiments, the x-axis drive motor 411, the y-axis drive motor 421 and the rotary motor 431 are servo motors to accurately control the distances moved along the x-axis and the y-axis and the angle of rotation along the z-axis.

[0091] Specifically in this embodiment, the supporting fixture 44 is adjusted in the y-axis direction according to the y-position of the glass material to be laminated and the y-position of the laminated glass material so that they are consistent in the y-axis direction. After the lamination of the multiple glass materials is completed, the supporting fixture 44 is driven by the x-axis moving component 41 to move along the x-axis direction to the bottom of the pressure-maintaining mechanism 60 for pressure-maintaining.

[0092] Please also see Figure 6 The glue dispensing mechanism 50 includes a glue dispensing drive component 51 and a glue dispensing component 52. The glue dispensing drive component 51 is drivingly connected to the glue dispensing component 52. The glue dispensing drive component 51 is used to drive the glue dispensing component 52 to move along the y-axis to move the glue dispensing component 52 above the glass material of the supporting fixture 44. The glue dispensing component 52 is used to dispense glue on the glass material.

[0093] The glue dispensing driving assembly 51 cooperates with the x-axis moving assembly 41 of the stacking mechanism 40 to achieve coating of any preset glue dispensing pattern on the glass material.

[0094] In some embodiments, the dispensing drive assembly 51 includes a dispensing drive motor 511 and a dispensing lead screw 512. The dispensing lead screw 512 extends along the y-axis direction. The dispensing assembly 52 is arranged on the movable end of the dispensing lead screw 512. The output shaft of the dispensing drive motor 511 is connected to the dispensing lead screw 512.

[0095] In some embodiments, the dispensing mechanism 50 further includes a dispensing guide rail 53. The dispensing guide rail 53 extends along the y-axis direction. A dispensing slide 531 is slidably provided on the dispensing guide rail 53. The dispensing drive assembly is provided on the dispensing guide rail 53, and specifically, the dispensing lead screw 512 is connected to the dispensing guide rail 53. The dispensing slide 531 slidably cooperates with the dispensing lead screw 512. The dispensing assembly 52 is fixed on the dispensing slide 531. The dispensing assembly 52 is slidably provided on the dispensing guide rail 53. The dispensing drive assembly 51 is used to drive the dispensing assembly 52 to move along the y-axis on the dispensing guide rail 53.

[0096] In some embodiments, the dispensing mechanism 50 further includes a z-axis fine-tuning component 54. The z-axis fine-tuning component 54 is disposed on the movable end of the dispensing screw 512 and is slidably disposed on the dispensing guide rail 53. The dispensing component 52 is disposed on the z-axis fine-tuning component 54. The z-axis fine-tuning component 54 is used to fine-tune the position of the dispensing component 52 along the z-axis direction.

[0097] Specifically, the z-axis fine-tuning assembly 54 includes a third slide 541, a third slide 542 and a third locking member 543. The glue dispensing assembly 52 is arranged on the third slide 541. The third slide 542 is arranged on the movable end of the glue dispensing screw 512.

[0098] In some embodiments, the glue dispensing component 52 is a glue dispensing pneumatic control module, which coordinates and adjusts the size of the glue dots and the amount of glue discharged through a pneumatic control system.

[0099] Please also see Figure 7 The pressure-maintaining mechanism 60 includes a pressure-maintaining driving component 61 and an elastic rubber head 62. The pressure-maintaining driving component 61 is drivingly connected to the elastic rubber head 62. The pressure-maintaining driving component 61 is used to drive the elastic rubber head 62 to move along the z-axis so as to hold the elastic rubber head 62 against the glass material of the supporting jig 44. The elastic rubber head 62 cooperates with the supporting jig 44 so that the stacked glass material supported on the supporting jig 44 is fully pressure-maintained.

[0100] The elastic rubber head 62 is a U-shaped rubber head, which is rich in elasticity and has uniform pressure. The end face section of the U-shaped rubber head is U-shaped, that is, the middle of the bottom is slightly protruding. This shape can ensure that in the process of pressing down the laminated glass, the protruding part is first pressed to the middle part of the glass for first pressing, and in the process of pressing down, the pressure in the middle part is slightly greater than the pressure at the edge, so that the glue is fully diffused to the edge. When the thickness of the overall glue layer is uniform, the thickness of the edge glue layer is further guaranteed, so that the etching liquid can be prevented from entering the glass through the pores at the edge and corroding the large surface of the glass. According to the setting of silicone with different hardness, the pressing pressure can be controlled by the pressing distance, and the UTG can be pressed simultaneously for multiple layers without breaking the UTG product. In addition, since a rubber head with a flat bottom is used, when the pressure is maintained, the glue in the glue layer between the stacked glass materials is subjected to uniform force, which can ensure that the thickness of each glue layer is the same after the pressure is maintained, and the thickness of the glue layer between the laminated sheets does not need to be measured. At the same time, because the stacking is carried out together for pressure maintenance, the total thickness of the stack can reach 10-20 layers, and the glue in the stack can be evenly distributed between the stacked glasses after dispensing and pressure maintenance, without internal bubbles and impurities, ensuring that the CNC polishing process can achieve a higher production yield under the condition of high polishing precision.

[0101] The x-axis moving assembly 41 drives the supporting fixture 44 to move along the x-axis to below the elastic rubber head 62 to cooperate with the pressure-maintaining mechanism 60 to maintain the pressure on the glass material.

[0102] In some embodiments, the pressure-maintaining drive assembly 61 includes a pressure-maintaining drive motor 611 and a pressure-maintaining screw 612. The pressure-maintaining screw 612 extends along the z-axis direction. The elastic rubber head 62 is arranged on the movable end of the pressure-maintaining screw 612. The output shaft of the pressure-maintaining drive motor 611 is connected to the pressure-maintaining screw 612. The pressure-maintaining screw 612 is used to convert the rotational drive of the pressure-maintaining drive motor 611 into a linear drive along the z-axis direction.

[0103] In some embodiments, the pressure-maintaining mechanism 60 also includes a pressure-maintaining guide rail 63. The pressure-maintaining guide rail 63 extends along the z-axis direction. A pressure-maintaining slide 631 is slidably provided on the pressure-maintaining guide rail 63. The pressure-maintaining drive assembly is provided on the pressure-maintaining guide rail 63, and specifically, the pressure-maintaining screw 612 is connected to the pressure-maintaining guide rail 63.

[0104] The material unloading mechanism 70 includes a material unloading guide rail 71, a material unloading drive assembly 72 and a gripper assembly 73. The material unloading guide rail 71 extends along the x-axis direction and is disposed at the downstream side of the x-axis moving assembly 41. The material unloading drive assembly 72 is slidably disposed on the material unloading guide rail 71, and the driving end of the material unloading drive assembly 72 is connected to the gripper assembly 73.

[0105] In some embodiments, the material unloading driving assembly 72 includes a first material unloading moving assembly 721 and a second material unloading moving assembly 722. The gripper assembly 73 includes a gripper driving member 731 and a material unloading gripper 732.

The driving end of the second material unloading moving assembly 722 is connected to the gripper driving member 731. The driving end of the gripper driving member 731 is connected to the material unloading gripper 732. The material unloading gripper 732 is used to grab the glass material after the pressure holding is completed under the drive of the gripper driving member 731. The first material unloading moving assembly 721 is used to drive the second material unloading moving assembly 722 to move along the x-axis on the material unloading guide rail 71 to transfer the glass material between the pressure holding mechanism 60 and the outside world. The second material unloading moving assembly 722 is used to drive the gripper driving member 731 to move along the z-axis, so that the material unloading gripper 732 grabs the glass material carried on the carrying fixture 44 .

[0106] In some embodiments, the first material removal moving assembly 721 is used to drive the second material removal moving assembly 722 to move along the x-axis to grab and transfer the glass material on the supporting fixture 44 to the UV curing conveyor belt to complete the UV curing of the glue.

[0107] In some embodiments, the first material removal moving component 721 is disposed on the pressure maintaining mechanism.

[0108] In some embodiments, the first material removal moving assembly 721, the second material removal moving assembly 722 and the gripper driving member 731 are respectively cylinders and their corresponding air circuit interfaces.

[0109] When the pressure-holding mechanism 60 is holding pressure, the material unloading gripper 732 can be moved to one side to avoid the pressure under the drive of the first material unloading moving component 721 and the second material unloading moving component 722, so as to give the elastic rubber head 62 space to press down and prevent collision. After the pressure holding is completed, the elastic rubber head 62 is driven by the pressure holding driving component 61 to return to the origin along the z-axis direction, and the material unloading gripper 732 moves to the bottom of the elastic rubber head 62 to grab the glass material that has finished the pressure holding.

[0110] The ultra-thin glass lamination device 100 provided in the present application has all mechanisms arranged on a frame 101, wherein a loading mechanism 10, a detection mechanism 30, and a stacking mechanism 40 are arranged in sequence, and a transfer mechanism 20 is located above them; a glue dispensing mechanism 50 is located above the stacking mechanism 40; a pressure-maintaining mechanism 60 and a unloading mechanism 70 are located near the glue dispensing mechanism 50 and also above the stacking mechanism 40. Such a layout can realize the one-way circulation of the entire product, while ensuring the accuracy and stability of the product, so as to obtain the maximum utilization rate in a limited space.

[0111] The traditional lamination processing scheme lacks a standard automated "loading and unloading process-glue dispensing-lamination-pressure holding" process, and the number of laminations at a time is generally 3-5, and it is impossible to stack more than 10 products, so the processing efficiency is low. In this application, the glass material is manually placed on the first loading platform 11 and the second loading platform 15, and the first loading moving component 12 and the second loading moving component 16 drive it to move back and forth. After the glass material is transferred to the position, the gripping component 23 absorbs the glass material, and the glass material is photographed through the lens 311 to obtain the product features, thereby visually positioning the glass material. Subsequently, the position of the carrier fixture 44 is adjusted by the x-axis moving component 41, the y-axis moving component 42, and the z-axis rotating component 43, so that the gripping component 23 accurately places the absorbed glass material on the carrier fixture 44. Subsequently, the glue dispensing drive component 51 cooperates with the x-axis moving component 41 of the stacking mechanism 40, so that the glue dispensing component 52 performs glue dispensing operations on the glass material on the carrier fixture 44 according to the set path and glue amount. Then, the "loading-glue dispensing" process of the glass material is repeated many times to achieve the stacking of multiple pieces of glass material. After reaching the set target number of stacking layers, the x-axis moving component 41 drives the bearing fixture 44 to move to the bottom of the elastic rubber head 62, and the elastic rubber head 62 is used to maintain the pressure of the stacked glass material to complete the lamination operation. Subsequently, it is grabbed by the unloading gripper 732 and sent to the outside through the first unloading moving component 721 for subsequent processing. The processing efficiency is high, and the overall stability of the laminated product can be achieved to meet the needs of subsequent CNC processing.

[0112] Since the edge of the ultra-thin glass before alignment and lamination is unprocessed, the product at this time is larger than the external dimensions of the final product. Therefore, during the lamination process, any deflection or offset of the product will increase the area of ​​the non-overlapped part of the ultra-thin glass after lamination, and will also increase the depth that needs to be removed in the ultra-thin glass edge processing process, which reduces the overall processing efficiency and even leads to an increase in defective products during processing. The ultra-thin glass lamination device 100 provided in the present application combines dispensing and pressure-maintaining of the glue head. The intermediate assembly and stacking process uses the lens 311 positioning and the gripping component 23 suction program to complete automatic loading and unloading, and cooperates with the stacking mechanism 40 for automatic alignment. During the lamination process, high-precision matching is achieved, the alignment accuracy of the lamination is improved, and each layer of glass is aligned without offset, reducing the movement deviation, thereby achieving accurate UTG stacking alignment and uniform pressure-maintaining lamination, thereby achieving the refinement of the product edge flatness, preventing the problem of easy breakage during lamination, and improving the efficiency and yield of subsequent UTG processing.

[0115] The transfer guide rail 21, the first guide rail 46 and the unloading guide rail 71 all extend along the x-axis direction and are parallel to each other, so as to make the overall equipment move more compactly in the x-axis direction, improve space utilization, facilitate position adjustment, and also help to improve the accuracy during alignment.

[0116] The first slide rail 13 and the glue dispensing guide rail 53 both extend along the y-axis direction and are parallel to each other, which facilitates the arrangement of the feeding mechanism 10 and the glue dispensing mechanism 50 in the overall equipment arranged in the x-axis direction, improves space utilization, facilitates position adjustment, and also helps to improve the alignment accuracy during feeding and glue dispensing.

[0120] Step S102: grabbing the glass material on the loading mechanism through the transfer mechanism.

[0121] Step S103: the glass material grasped by the transfer mechanism is inspected by a detection mechanism to determine the product characteristics of the grasped glass material.

[0122] Step S104: the stacking mechanism adjusts its position according to the product features detected by the detection mechanism.

[0123] Step S105: the transfer mechanism accurately places the grabbed glass material on the stacking mechanism.

[0124] Step S106: performing a glue dispensing operation on the glass material placed on the stacking mechanism by using a glue dispensing mechanism.

[0125] Step S107: Repeat the above-mentioned material loading and dispensing process until a preset number of glass materials are stacked to obtain a stacked glass material.

[0126] Specifically, steps S102, S103, S104, S105 and S106 are repeatedly performed so that the glass materials are stacked one by one on the stacking mechanism until a preset number of glass materials are stacked to obtain stacked glass materials.

[0127] Step S108: maintaining pressure on the stacked glass material carried by the stacking mechanism through a pressure maintaining mechanism to complete lamination.

[0128] Step S109: unloading the glass material after being stacked on the stacking mechanism through the unloading mechanism.
