Abstract
Description
Technical Field
[0001] This invention relates to a method for assembling multilayer glass panels. Background Technology
[0002] In the production process of multi-layer glass components (such as insulated glass, laminated multi-layer glass, etc.), multiple pieces of glass need to be assembled into a multi-layer structure through spacers. The spacers are adhesive and can directly bond and fix the glass on both sides.
[0003] In existing technologies, the assembly of multi-layer glass components often employs a combination of manual positioning and manual placement of spacers: operators must manually align the positions of multiple glass panes, then attach the spacers to designated locations on the glass surfaces, and finally attach the subsequent glass panes. This method has the following drawbacks:
[0004] 1. Low efficiency: It relies on manual operation. The positioning of each piece of glass and the placement of the spacer strips require separate time, which cannot meet the needs of mass production.
[0005] 2. Poor accuracy: Manual positioning is easily affected by operating experience and visual errors, resulting in large deviations in glass alignment and spacer position, making it difficult to guarantee the flatness and sealing of the multi-layer structure;
[0006] 3. Unstable quality: Poor consistency in manual operation leads to large fluctuations in assembly quality between different batches or even within the same batch, which can easily cause problems such as spacer strip misalignment and glass misalignment, affecting the performance of the final product (such as heat insulation and sound insulation).
[0007] Therefore, there is an urgent need for an assembly method that can achieve automated positioning and clamping, and improve the efficiency and accuracy of multi-layer glass assembly, in order to overcome the shortcomings of existing technologies. Summary of the Invention
[0008] To address the aforementioned issues, this invention provides a method for assembling multi-layer glass panels. The method utilizes a double-clamping groove design in the first positioning and clamping mechanism to achieve scene-specific positioning of different glass layers. The positioning platform precisely defines the position of the spacer strips, and the liftable worktable enables layer bonding. The second positioning and clamping mechanism further enhances the stability of the intermediate glass layer, thus solving the efficiency and accuracy problems of traditional manual assembly.
[0009] The technical solution adopted in this invention is:
[0010] A method for assembling multi-layer glass panels, wherein the assembly system used in the assembly method includes an assembly station, a controller, a press, and a robot. The assembly station includes a base, a worktable, a first positioning and clamping mechanism, and a second positioning and clamping mechanism. The press is positioned directly above the worktable. The worktable, the press, and the robot are all electrically connected to the controller. The press is used to press the multi-layer glass panels together. The robot is used to transport the glass workpiece to the assembly station and, after assembly, to unload the multi-layer glass panels from the assembly station.
[0011] The worktable is mounted on the base and has lifting and positioning functions. The first and second positioning clamping mechanisms are both fixed to the base and arranged around the worktable for clamping and positioning the glass workpiece on the worktable. The first positioning clamping mechanism has a first lower glass clamping groove and a first upper glass clamping groove sequentially formed from bottom to top on the workpiece side of its front end. The first lower glass clamping groove is used for clamping and positioning the inner and middle glass panes, and the first upper glass clamping groove is used for clamping and positioning the outer glass pane and pre-clamping and positioning the middle glass pane. An inwardly protruding positioning platform is provided between the first lower glass clamping groove and the first upper glass clamping groove of the first positioning clamping mechanism. The positioning platform is used to limit the position of the spacer strip placed on the upper surface of the glass workpiece. The second positioning clamping mechanism has a second glass clamping groove formed on the workpiece side of its front end, which is used for clamping and positioning the middle glass pane.
[0012] The assembly method includes the following steps:
[0013] Step 1) Initial state setting: The controller controls both the first and second positioning clamping mechanisms to remain retracted, while simultaneously controlling the worktable to rise to the top and be flush with the bottom surface of the first lower glass clamping groove;
[0014] Step 2) Inner glass placement: The controller controls the robot to place the inner glass on the worktable surface, with the edge of the inner glass naturally aligned with the entrance of the first glass clamping groove;
[0015] Step 3) Inner glass clamping: The controller controls the first positioning and clamping mechanism to push out, and the edge of the inner glass is embedded into the first lower glass clamping groove to achieve clamping of the inner glass;
[0016] Step 4) Positioning and placing the spacer strip on the inner glass: Place the spacer strip along the inner side of the positioning platform. The positioning platform directly limits the annular position of the spacer strip. At this time, the upper surface of the spacer strip is lower than the bottom surface of the first upper glass clamping groove.
[0017] Step 5) Pre-positioning of the middle glass: The controller controls the robot to put the middle glass into the opening of the first upper glass clamping groove, and the edge is embedded in the first upper glass clamping groove;
[0018] Step 6) Secondary clamping of the middle glass: The controller controls the second positioning and clamping mechanism to push out, and the edge of the middle glass is embedded into the second glass clamping groove to achieve clamping of the middle glass;
[0019] Step 7) Bonding the spacer strip to the middle glass: The controller controls the worktable to rise slightly, and the inner glass moves upward with the worktable, causing the spacer strip on the inner glass to move upward until the top surface of the inner glass abuts against the top surface of the first lower glass clamping groove. At this time, the top surface of the spacer strip and the bottom surface of the middle glass are completely in contact, and the adhesive spacer strip naturally bonds the two together, thus achieving the bonding of the inner glass, the spacer strip and the middle glass.
[0020] Step 8) Remove the original positioning and new positioning reference settings: The controller first controls the second positioning clamping mechanism to retract, removes the clamping of the second positioning clamping mechanism, then controls the worktable to descend slightly, so that the inner glass sheet is separated from the top surface of the first lower glass clamping groove, then retracts the first positioning clamping mechanism to release the constraint, and then controls the worktable to continue to descend until the top surface of the middle glass sheet is flush with the bottom surface of the first lower glass clamping groove, and finally controls the first positioning clamping mechanism to push out, so that the edge of the middle glass sheet is embedded in the first lower glass clamping groove;
[0021] Step 9) Positioning and placing the spacer strip on the middle glass: Place the spacer strip along the inner side of the positioning platform. The positioning platform directly limits the annular position of the spacer strip. At this time, the upper surface of the spacer strip is lower than the bottom surface of the first upper glass clamping groove.
[0022] Step 10) Outer glass positioning: The controller controls the robot to put the outer glass into the opening of the first upper glass clamping groove, and the edge is embedded in the first upper glass clamping groove. The first upper glass clamping groove directly provides the final positioning for the outer glass.
[0023] Step 11) Bonding the spacer strip to the outer glass: The controller controls the worktable to rise slightly, and the middle glass rises with the worktable, which drives the spacer strip on the middle glass to move upward until the top surface of the middle glass abuts against the top surface of the first lower glass clamping groove. At this time, the top surface of the spacer strip and the bottom surface of the outer glass are completely in contact, and the adhesive spacer strip naturally bonds the two together, thus achieving the bonding of the middle glass, the spacer strip and the outer glass.
[0024] Step 12) Remove positioning constraints: The controller first controls the second positioning clamping mechanism to retract, removing the clamping of the second positioning clamping mechanism. Then, it controls the worktable to descend slightly, separating the middle glass from the top surface of the first lower glass clamping groove. Finally, it controls the first positioning clamping mechanism to retract, releasing the constraints.
[0025] Step 13) Pressing and fixing: The controller controls the press to apply downward pressure to press the multi-layer glass panel firmly.
[0026] Preferably, the height of the positioning platform is slightly less than the thickness of the spacer strip, with a difference ranging from 1 to 4 mm.
[0027] Preferably, the height of the first lower glass clamping groove is slightly greater than the thickness of the glass workpiece, with a difference ranging from 2 to 5 mm.
[0028] Preferably, the top of the first upper glass clamping groove is open, allowing the glass workpiece to be positioned to be placed directly from above.
[0029] Preferably, the lifting and positioning of the worktable is achieved by a cylinder drive assembly or a screw jack, which can be used in conjunction with a photoelectric limit sensor, with a lifting and positioning accuracy of ±0.1mm.
[0030] Preferably, the second positioning and clamping mechanism and the first positioning and clamping mechanism are respectively arranged around the worktable to achieve circumferential clamping of the glass workpiece from all sides.
[0031] The beneficial effects of this invention are as follows:
[0032] 1. Improve assembly efficiency: Automatic clamping via worktable lifting and positioning clamping mechanism replaces manual positioning and adjustment, significantly shortening the assembly time of a single multi-layer glass unit and adapting to mass production;
[0033] 2. Improve positioning accuracy: The clamping groove dimensions of the first and second positioning clamping mechanisms are matched with the glass thickness, and the positioning stage precisely limits the position of the spacer strip, avoiding visual errors caused by manual operation, and ensuring that the glass alignment and spacer strip position deviation are ≤0.5mm;
[0034] 3. Ensure stable quality: Strong operational consistency avoids quality fluctuations caused by differences in the experience of different operators, and effectively guarantees the flatness and sealing of multi-layer glass components;
[0035] 4. High ease of operation: The first upper glass clamping slot adopts a top opening design, allowing the glass to be directly inserted from the top without the need for lateral adjustment; the retraction and ejection actions of the positioning clamping mechanism can be controlled pneumatically or electrically, reducing the labor intensity of operators.

[0048] Example 1
[0049] like Figure 1-5 As shown, for a three-layer glass panel structure composed of inner glass, middle glass, and outer glass, where the inner glass, middle glass, and outer glass refer to different layers of the multi-layer glass panel, placed sequentially according to the assembly order, and the inner glass, middle glass, and outer glass have the same thickness, this invention provides a method for assembling a multi-layer glass panel. The assembly system used in this method includes an assembly station a, a controller b, a press machine c, and a robot d. The assembly station a includes a base a1, a worktable a2, a first positioning and clamping mechanism a3, and a second positioning and clamping mechanism a4. The press machine c is located directly above the worktable a2. The worktable a2, the press machine c, and the robot d are all electrically connected to the controller b. The press machine c is used to press the multi-layer glass panel, and the robot d is used to transport the glass workpiece to the assembly station a. Simultaneously, after assembly, the multi-layer glass panel on the assembly station a is unloaded. The controller b is electrically connected to the worktable a2, the press machine c, the robot d, and the positioning and clamping mechanisms via wired or wireless communication, preferably using a PLC. The controller enables action timing coordination;
[0050] The worktable a2 is mounted on the base a1 and has a lifting and positioning function. The lifting and positioning of the worktable a2 is achieved by a cylinder drive assembly or a screw jack. The first positioning and clamping mechanism a3 and the second positioning and clamping mechanism a4 are both fixed on the base a1 and arranged around the worktable a2 for clamping and positioning the glass workpiece on the worktable a2. The front end of the first positioning and clamping mechanism a3 has a first lower glass clamping groove a31 and a first upper glass clamping groove a32 sequentially formed from bottom to top on the side facing the workpiece. The glass clamping groove a31 is used for clamping and positioning the inner and middle glass sheets. The height of the first lower glass clamping groove a31 is slightly greater than the thickness of the glass workpiece, with a difference range of 2-5mm. The first upper glass clamping groove a32 is used for clamping and positioning the outer glass sheet and pre-clamping and positioning the middle glass sheet. The top of the first upper glass clamping groove a32 is open, allowing the glass workpiece to be positioned to be placed directly from above. The groove wall of the first upper glass clamping groove a32 can be provided with a guide slope, allowing the glass to slide into the groove along the slope when placed in. The gap between the groove wall and the edge of the glass is ≤0.2mm to ensure positioning accuracy. A positioning platform a33 is provided between the first lower glass clamping groove a31 and the first upper glass clamping groove a32 of the positioning clamping mechanism a3. The positioning platform a33 is used to limit the position of the spacer strip placed on the upper surface of the glass workpiece. The height of the positioning platform a33 is slightly less than the thickness of the spacer strip, with a difference range of 1-4mm. In specific value selection, it is necessary to ensure that the thickness difference between the positioning platform and the spacer strip is less than the difference between the height of the first lower glass clamping groove a31 and the thickness of the glass workpiece. The front end of the second positioning clamping mechanism a4 has a second glass clamping groove a41 on the side facing the workpiece, and the first... The bottom surface of the second glass clamping groove a41 is flush with the bottom surface of the first upper glass clamping groove a32. The second glass clamping groove a41 is used for clamping and positioning the middle glass sheet. The second positioning clamping mechanism a4 and the first positioning clamping mechanism a3 are respectively arranged around the worktable a2 to achieve circumferential clamping of the glass workpiece. Specifically, the first positioning clamping mechanism a3 is provided around the worktable a2, and the second positioning clamping mechanism a4 is also provided around the worktable a2. In this invention, the first positioning clamping mechanism a3 and the second positioning clamping mechanism a4 can be driven and clamped by a cylinder or a hydraulic cylinder.
[0051] The assembly method includes the following steps:
[0052] Step 1) Initial state setting: Controller b controls the first positioning clamping mechanism a3 and the second positioning clamping mechanism a4 to remain retracted (without obstructing glass placement), while controlling the worktable a2 to rise to the top and be flush with the bottom surface of the first lower glass clamping groove a31. This state provides a "placement and positioning" reference for the inner glass, avoiding subsequent adjustments to the worktable a2.
[0053] Step 2) Inner glass placement: Controller b controls robot d to place the inner glass on the surface of worktable a2. The edge of the inner glass is naturally aligned with the entrance of the first lower glass clamping groove a31, without the need for realignment.
[0054] Step 3) Inner glass clamping: Controller b controls the first positioning clamping mechanism a3 to push out, and the edge of the inner glass is embedded in the first lower glass clamping groove a31 to clamp the inner glass. The lateral position of the inner glass is fixed by the lateral constraint of the groove wall, providing a stable reference for the subsequent placement of the spacer strip.
[0055] Step 4) Positioning and placing the spacer strip on the inner glass: Place the spacer strip along the inner side of the positioning platform a33 (this can be done manually or with a robot arm controlled by a controller; if a robot arm is used, the degree of automation is higher). The positioning platform a33 directly defines the annular position of the spacer strip. At this time, the upper surface of the spacer strip is lower than the bottom surface of the first upper glass clamping groove a32, which prevents the bottom surface of the glass from contacting the spacer strip prematurely and causing it to shift when the middle glass is placed later.
[0056] Step 5) Pre-positioning of the middle glass: Controller b controls the robot d to insert the middle glass into the opening of the first upper glass clamping groove a32, with its edge embedded in the first upper glass clamping groove a32. At this time, the bottom surface of the middle glass separates from the spacer strip (this is achieved by the difference between the height of the first lower glass clamping groove a31 and the thickness of the glass workpiece, and the difference between the height of the positioning table 33 and the thickness of the spacer strip), thus achieving "pre-positioning without adhesion" and preventing the spacer strip from being prematurely glued off-center.
[0057] Step 6) Secondary clamping of the middle glass: Controller b controls the second positioning and clamping mechanism a4 to push out, and the edge of the middle glass is embedded in the second glass clamping groove a41 to achieve clamping of the middle glass;
[0058] Step 7) Bonding the spacer strip to the middle glass: Controller b controls the worktable a2 to rise slightly. The inner glass rises with the worktable a2, which drives the spacer strip on the inner glass to move upward until the top surface of the inner glass abuts against the top surface of the first lower glass clamping groove a31. At this time, the top surface of the spacer strip and the bottom surface of the middle glass are completely in contact, and the adhesive spacer strip naturally bonds the two together, thus achieving the bonding of the inner glass, the spacer strip and the middle glass.
[0059] Step 8) Remove the original positioning and new positioning reference settings: Controller b first controls the second positioning clamping mechanism a4 to retract, removing the clamping of the second positioning clamping mechanism a4 (since at this time the bottom surface of the spacer is flush with the top surface of the first lower glass clamping groove, and the height of the spacer is slightly less than the height of the positioning table by 1-4mm, there is a gap between the bottom surface of the middle glass and the bottom surface of the first upper glass clamping groove. Removing the second positioning clamping mechanism directly will not exert a lateral force on the middle glass, so the second positioning clamping mechanism can be removed directly). Then control... The worktable a2 is lowered slightly to separate the inner glass from the top surface of the first lower glass clamping groove a31. Then the first positioning clamping mechanism a3 is retracted to release the constraint. The worktable a2 is then controlled to continue to lower until the top surface of the middle glass is flush with the bottom surface of the first lower glass clamping groove a31. Finally, the first positioning clamping mechanism a3 is controlled to push out, and the edge of the middle glass is embedded in the first lower glass clamping groove a31. At this time, the positioning reference is switched from "inner glass" to "middle glass", providing the same positioning accuracy as the inner glass for the subsequent assembly of the outer glass.
[0060] Step 9) Positioning and placing the spacer on the middle glass: Place the spacer along the inner side of the positioning platform a33. The positioning platform a33 directly defines the annular position of the spacer. At this time, the upper surface of the spacer is lower than the bottom surface of the first upper glass clamping groove a32 to prevent the outer glass from contacting the spacer in advance.
[0061] Step 10) Outer glass positioning: Controller b controls robot d to put the outer glass into the opening of the first upper glass clamping groove a32, and the edge is embedded in the first upper glass clamping groove a32. The first upper glass clamping groove a32 directly provides the final positioning for the outer glass.
[0062] Step 11) Bonding the spacer strip to the outer glass: Controller b controls the worktable a2 to rise slightly. The middle glass rises with the worktable a2, which drives the spacer strip on the middle glass to move upward until the top surface of the middle glass abuts against the top surface of the first lower glass clamping groove a31. At this time, the top surface of the spacer strip and the bottom surface of the outer glass are completely in contact, and the adhesive spacer strip naturally bonds the two together, thus achieving the bonding of the middle glass, the spacer strip and the outer glass.
[0063] Step 12) Remove positioning constraints: Controller b first controls the second positioning clamping mechanism a4 to retract, removing the clamping of the second positioning clamping mechanism a4. Then, it controls the worktable a2 to descend slightly, so that the middle glass sheet separates from the top surface of the first lower glass clamping groove a31. Finally, it controls the first positioning clamping mechanism a3 to retract, releasing the constraints and preventing the clamping groove from obstructing the subsequent pressing action, while not affecting the already bonded multi-layer structure.
[0064] Step 13) Pressing and fixing: Controller b controls press c to apply a downward pressure of 0.5-1MPa for 3-5 seconds. The pressure is determined experimentally based on the glass thickness and the adhesion of the spacer strip. Here, 0.5-1MPa is the commonly used pressure range obtained by the applicant through testing. The multi-layer glass panel is pressed firmly, and the pressure eliminates the tiny gaps between the spacer strip and the glass, strengthens the adhesion, and ensures the flatness and sealing of the final product.
[0065] The core working principle of this technical solution is: by coordinating the structured positioning and clamping components, the liftable worktable, and the precise spacer positioning structure, it replaces manual positioning and operation, and achieves "precise positioning - layer bonding - stable fixation" of multi-layer glass (inner sheet, middle sheet, outer sheet) and adhesive spacers, ultimately solving the problems of "low efficiency, poor accuracy, and unstable quality" in traditional manual assembly.
[0066] The structural design of each component determines its functional positioning and is the foundation for achieving precise assembly of the entire solution, as detailed below:
[0067] 1. Base: Support and reference positioning foundation
[0068] The base provides a fixed mounting reference for all functional components (worktable, first / second positioning and clamping mechanism), ensuring that the relative positions of each component in space remain stable. Its core function is:
[0069] Eliminate positioning deviations caused by component shaking during assembly; provide rigid support for the lifting and positioning clamping mechanism of the worktable to prevent deformation under force from affecting positioning accuracy;
[0070] 2. Adjustable worktable: The core of dynamic glass height adjustment.
[0071] The worktable has a "lifting and positioning function" (driven by cylinders, screw jacks, etc.), and its working principle revolves around "adjusting the glass height to adapt to different positioning needs":
[0072] Initial positioning reference: In the initial state, the top support surface of the worktable is flush with the bottom surface of the first lower glass clamping groove, ensuring that after the inner glass is placed, its edge can be accurately embedded into the first lower glass clamping groove without the need for additional height adjustment;
[0073] Spacer strip adhesion fit: Utilizing the design that "the height of the first glass clamping groove is slightly greater than the glass thickness", the worktable can drive the glass to rise and fall slightly - during the rise and fall, the glass will not be vertically stuck by the clamping groove, thereby achieving "precise contact between the spacer strip and the bottom surface of the previous glass" (such as the inner glass as the worktable rises, causing the spacer strip to fit against the middle glass).
[0074] Positioning object switching: When it is necessary to switch from "positioning inner glass" to "positioning middle glass" during the assembly process, the worktable can be lowered so that the top surface of the middle glass is flush with the bottom surface of the first lower glass clamping groove, so that the first lower glass clamping groove can accurately clamp the middle glass, providing a new benchmark for the subsequent assembly of outer glass.
[0075] 3. First positioning and clamping mechanism: the "main positioning core" of multi-layered glass.
[0076] This mechanism, through a composite structure of "double clamping grooves + positioning stage," achieves "scene-specific positioning" of different glass elements (inner sheet, middle sheet, outer sheet), which is key to precision control. The specific principle is as follows:
[0077] Functional division of labor between the dual clamping slots:
[0078] The first glass clamping groove: The groove height is slightly greater than the thickness of a single piece of glass, and it is only used for the final clamping and positioning of "glass other than the outer glass" (inner glass, middle glass) - its size design ensures that the glass can be clamped stably (without lateral displacement), and also reserves space for the worktable to drive the glass to rise and fall (without vertical jamming).
[0079] First upper glass clamping groove: Top opening design (facilitates direct insertion of glass from above), serving two positioning functions: ① Final precise positioning of the "outer glass" (the outer glass does not need to participate in intermediate positioning switching and is directly fixed through this groove); ② Pre-positioning of the "middle glass" (the middle glass is initially embedded in this groove to avoid direct contact with the lower spacer strip and prevent the spacer strip from shifting).
[0080] Positioning platform: Precise positioning of spacer strip: The "inwardly protruding positioning platform" between the first lower glass clamping groove and the first upper glass clamping groove is the "physical positioning reference" of the adhesive spacer strip. When placing the spacer strip, the outer edge of the spacer strip fits against the positioning platform, directly limiting its annular position on the glass surface, avoiding visual errors when placing manually, and ensuring that each ring of spacer strip is in the preset "adhesive area".
[0081] 4. Second positioning and clamping mechanism: the "auxiliary stabilizing core" of the middle glass pane.
[0082] This facility only has a "second glass clamping groove," and its working principle revolves around "enhancing the positioning stability of the middle glass pane."
[0083] The middle glass is the "intermediate connecting layer" in a multi-layered structure. It needs to be pre-positioned by the first upper glass clamping groove and then clamped again by the second glass clamping groove. This double positioning can prevent the middle glass from shifting laterally when the worktable is raised, and ensure that the spacer strip and the bottom surface of the middle glass are accurately aligned.
[0084] This invention achieves a comprehensive optimization of traditional manual assembly through "precision-defined structural design and efficiency-enhancing dynamic collaboration":
[0085] Precision assurance: The positioning table limits the position of the spacer strip, the double clamping groove limits the position of the glass, and the lifting of the worktable controls the bonding distance. This triple precision control ensures that the glass alignment deviation is ≤0.5mm and the spacer strip position deviation is ≤0.3mm.
[0086] Efficiency improvement: The actions of each component can be achieved through automated control (no manual adjustment required), and the assembly time of a single multi-layer glass unit is reduced by more than 60% compared to manual assembly;
[0087] Stable quality: Automated collaborative operation eliminates the differences in human experience, significantly improving the consistency of bonding strength, flatness and sealing of each batch of products, and reducing the defect rate to below 1%.
[0088] This invention provides a detailed description of the assembly of a three-layer glass panel through embodiments. However, this invention can also be used for the assembly of more layers of glass panels. It can be achieved by simply repeating steps 8-11. For example, when assembling a four-layer glass panel, steps 8-11 can be repeated once. The additional steps include positioning the middle glass, placing the spacer strip, and bonding the middle glass. The positioning reference of the middle glass is switched to be consistent with that of the middle glass. When assembling a five-layer glass panel, steps 8-11 can be repeated twice.
[0089] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this invention should be considered within the scope of protection of this invention.

The worktable (a2) is mounted on the base (a1) and has a lifting and positioning function; the first positioning clamping mechanism (a3) and the second positioning clamping mechanism (a4) are both fixed on the base (a1) and arranged around the worktable (a2) for clamping and positioning the glass workpiece on the worktable (a2); the front end of the first positioning clamping mechanism (a3) facing the workpiece has a first lower glass clamping groove (a31) and a first upper glass clamping groove (a32) sequentially opened from bottom to top, the first lower glass clamping groove (a31) is used for clamping and positioning the inner glass and the middle glass, and the first upper glass clamping groove (a32) is used for clamping and positioning the outer glass and the middle glass. The clamping and positioning mechanism (a3) has an inwardly protruding positioning platform (a33) between the first lower glass clamping groove (a31) and the first upper glass clamping groove (a32) of the first positioning clamping mechanism (a3). The positioning platform (a33) is used to limit the position of the spacer strip placed on the upper surface of the glass workpiece. The second positioning clamping mechanism (a4) has a second glass clamping groove (a41) on the front end facing the workpiece. The second glass clamping groove (a41) is used for clamping and positioning the middle glass sheet. The assembly method includes the following steps: Step 1) Initial state setting: The controller (b) controls the first positioning clamping mechanism (a3) and the second positioning clamping mechanism (a4) to remain retracted, while controlling the worktable (a2) to rise to Step 2) Placing the inner glass: The controller (b) controls the robot (d) to place the inner glass on the surface of the worktable (a2), and the edge of the inner glass is naturally aligned with the entrance of the first lower glass clamping groove (a31); Step 3) Clamping the inner glass: The controller (b) controls the first positioning clamping mechanism (a3) to push out, and the edge of the inner glass is embedded in the first lower glass clamping groove (a31) to achieve clamping of the inner glass; Step 4) Positioning and placing the spacer strip on the inner glass: The spacer strip is placed along the inside of the positioning platform (a33), and the positioning platform (a33) directly defines the annular position of the spacer strip. At this time, the upper surface of the spacer strip is lower than the bottom surface of the first upper glass clamping groove (a32);Step 5) Pre-positioning of the middle glass: The controller (b) controls the robot (d) to insert the middle glass into the opening of the first upper glass clamping groove (a32), with its edge embedded in the first upper glass clamping groove (a32); Step 6) Secondary clamping of the middle glass: The controller (b) controls the second positioning clamping mechanism (a4) to push out, and the edge of the middle glass is embedded in the second glass clamping groove (a41), thus clamping the middle glass; Step 7) Bonding of the spacer strip to the middle glass: The controller (b) controls the worktable (a2) to rise slightly, and the inner glass rises with the worktable (a2), causing the spacer strip on the inner glass to move upward until the top surface of the inner glass abuts against the top surface of the first lower glass clamping groove (a31). At this time, the top surface of the spacer strip is bonded to the middle glass. The bottom surfaces of the glass panes are fully in contact, and the adhesive spacer naturally bonds the two, achieving the bonding of the inner glass pane, the spacer, and the middle glass pane; Step 8): Remove the original positioning and new positioning reference settings: The controller (b) first controls the second positioning clamping mechanism (a4) to retract, removing the clamping of the second positioning clamping mechanism (a4), then controls the worktable (a2) to descend slightly, separating the inner glass pane from the top surface of the first lower glass clamping groove (a31), then retracts the first positioning clamping mechanism (a3) to release the constraint, and then controls the worktable (a2) to continue descending until the top surface of the middle glass pane is flush with the bottom surface of the first lower glass clamping groove (a31), finally controlling the first positioning clamping mechanism (a3) to push out, and the edge of the middle glass pane is embedded in the first lower glass clamping groove (a31). 31); Step 9) Positioning and placing the spacer strip on the middle glass: Place the spacer strip along the inner side of the positioning table (a33). The positioning table (a33) directly defines the annular position of the spacer strip. At this time, the upper surface of the spacer strip is lower than the bottom surface of the first upper glass clamping groove (a32); Step 10) Positioning the outer glass: The controller (b) controls the robot (d) to put the outer glass into the opening of the first upper glass clamping groove (a32). The edge is embedded in the first upper glass clamping groove (a32). The first upper glass clamping groove (a32) directly provides the final positioning for the outer glass; Step 11) Bonding the spacer strip to the outer glass: The controller (b) controls the worktable (a2) to rise slightly. The middle glass rises with the worktable (a2), driving the spacer strip on the middle glass to rise. The spacer moves upward until the top surface of the middle glass abuts against the top surface of the first lower glass clamping groove (a31). At this point, the top surface of the spacer is fully in contact with the bottom surface of the outer glass, and the adhesive spacer naturally bonds the two together, achieving the bonding of the middle glass, spacer, and outer glass. Step 12): Remove positioning constraints: The controller (b) first controls the second positioning clamping mechanism (a4) to retract, removing the clamping of the second positioning clamping mechanism (a4). Then, it controls the worktable (a2) to descend slightly, separating the middle glass from the top surface of the first lower glass clamping groove (a31). Finally, it controls the first positioning clamping mechanism (a3) to retract, releasing the constraints. Step 13): Press and fix: The controller (b) controls the press (c) to apply downward pressure, pressing the multi-layer glass panel firmly.
