Description

Technical Field

[0001] This application relates to the field of automotive glass manufacturing, and in particular to a tooling for installing irregularly shaped glass accessories. Background Technology

[0002] Fixtures for installing irregularly shaped glass accessories are commonly used in the deep processing of automotive irregularly shaped glass. They are specialized process equipment used to precisely assemble accessories such as pins and edge strips with the irregularly shaped glass body. Their positioning accuracy and assembly stability directly affect the sealing performance of the final product and the overall vehicle assembly quality. However, in the processing of automotive irregularly shaped glass, some pieces are small in size. When using conventional fixtures for positioning, the irregularly shaped glass is prone to displacement, and accessories are easily misaligned; the relative positional accuracy of accessories such as pins cannot be guaranteed. Currently, relying on manual assistance for positioning is not only inefficient but also poses a safety hazard of personnel injury. Therefore, it is necessary to develop specialized installation fixtures for accessories adapted to small-sized irregularly shaped glass. Summary of the Invention

[0003] In view of this, this application provides an installation fixture for irregularly shaped glass accessories to solve at least one problem existing in the prior art.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0005] This application provides an installation fixture for irregularly shaped glass accessories, including:

[0006] Workbench;

[0007] A support mechanism is provided on the workbench and configured to support the irregularly shaped glass from the bottom.

[0008] A pre-positioning mechanism is set on the workbench and includes multiple fixed first positioning members configured to define the horizontal position of the irregular glass from all sides.

[0011] In one optional embodiment, the second positioning member includes a clamping post that clamps the irregularly shaped glass from a horizontal side. The surface of the clamping post that contacts the irregularly shaped glass has a positioning groove, and the width of the positioning groove in the vertical direction is adapted to the thickness of the irregularly shaped glass.

[0013] In one optional embodiment, the first positioning member includes a column and a positioning boss. The bottom end of the column is fixed to the worktable, and the positioning boss is formed by protruding from the upper end of the column toward the irregular glass. The end of the positioning boss facing the irregular glass includes a positioning plane.

[0014] In one optional embodiment, the longitudinal cross-sectional shape of the positioning groove is a trapezoid with the groove opening larger than the groove bottom, and the thickness of the irregularly shaped glass is between the dimensions of the groove bottom and the groove opening.

[0016] In one alternative embodiment, the first accessory is a nail post, and the first receiving groove is a contour groove that matches the outer contour shape of the nail post.

[0017] In an optional embodiment, the tooling further includes:

[0018] A glass driving component is disposed on the worktable.

The glass driving component includes a vacuum suction cup, through which the irregularly shaped glass is adsorbed onto the glass driving component.

[0019] In an optional embodiment, the tooling further includes:

[0020] The second accessory assembly mechanism is disposed on the workbench and includes a second receiving slot for placing the second accessory; the second accessory assembly mechanism can assemble the second accessory in the second receiving slot into the irregular glass when the irregular glass is lowered.

[0021] In an optional embodiment, the tooling further includes:

[0022] A clamping mechanism is disposed on the worktable and is configured to clamp the irregularly shaped glass from the top after the irregularly shaped glass is lowered, so as to cooperate with the assembly of the first accessory.

[0023] The irregular glass accessory installation fixture of this application embodiment initially defines the horizontal position of the irregular glass from all sides through a pre-positioning mechanism, and then the second positioning component in the main positioning mechanism, which can move horizontally, clamps the irregular glass from the side, realizing precise clamping and limiting of the irregular glass in the horizontal direction. At the same time, the first accessory assembly mechanism carries the accessory through the first receiving groove and moves up and down relative to the irregular glass to complete the abutment assembly.

Detailed Implementation

[0036] To make the technical solutions and beneficial effects of this application more obvious and understandable, the technical solutions in the embodiments of this application are clearly and completely described below by listing specific embodiments. Obviously, the embodiments of this application are not exhaustive, and the described embodiments are only some embodiments of this application, not all embodiments.

[0037] The exemplary embodiments disclosed in this application will now be described in more detail with reference to the accompanying drawings, providing detailed structures and steps to illustrate the technical solution of this application. Note that the drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used herein is for the purpose of describing particular embodiments only and should not be construed as limiting the technical solutions of this application.

[0039] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. To clearly define the inventive concept of this application and avoid confusion with its content, technical features well-known in the art and conventionally understood by those skilled in the art are not elaborated upon. Specifically, this document does not fully list all features of actual embodiments, nor does it provide a detailed description of well-known functions and structures.

[0040] The inventors of this application discovered during the research and development that existing fixtures for assembling irregularly shaped glass accessories typically use fixed blocks or simple clamps for positioning when assembling accessories of irregularly shaped glass of different specifications. Because irregularly shaped glass has complex edge contours and thickness tolerances compared to conventional glass, fixed positioning structures struggle to simultaneously ensure horizontal positioning accuracy and lateral clamping stability. This leads to the irregularly shaped glass being prone to shifting or wobbling during assembly, consequently affecting the assembly position accuracy and bonding quality of accessories such as nails and edge banding. This problem is not common knowledge in the industry, but rather a hidden technical defect discovered by the inventors through extensive failure analysis during long-term production practice. Understandably, in the fields of glass deep processing and automobile manufacturing, irregularly shaped glass refers to a general term for glass products with irregular outer contours, non-linear edges, or complex curved surface features, excluding regular geometric shapes such as circles, ellipses, and regular polygons.

[0041] Therefore, through further research and development, the inventors proposed the following technical solution.

[0042] To address the technical problems in related technologies, embodiments of this application provide an installation fixture for irregularly shaped glass accessories. (Reference) Figure 1 and Figure 2 The irregularly shaped glass accessory installation fixture includes:

[0043] Workbench 10;

[0044] A support mechanism 20 is disposed on the workbench 10 and configured to support the irregularly shaped glass 91 from the bottom.

[0045] The pre-positioning mechanism 30 is disposed on the worktable 10 and includes a plurality of fixed first positioning members, configured to define the horizontal position of the irregular glass 91 from all sides. The orthographic projection of the area enclosed by the first positioning members on the horizontal plane is greater than the orthographic projection of the irregular glass 91 on the horizontal plane.

[0046] The main positioning mechanism 40 is disposed on the worktable 10 and includes a plurality of horizontally movable second positioning members 41. The plurality of second positioning members 41 are configured to clamp and limit the horizontal position of the irregular glass 91 from all sides.

[0047] The first accessory assembly mechanism 50 is disposed on the workbench 10 and includes a first receiving groove 51 for placing the first accessory; the first accessory assembly mechanism 50 can move up and down relative to the irregular glass 91 so as to complete the assembly by moving the first accessory to abut against the irregular glass 91.

[0048] Unrestricted, the workbench 10 can serve as the supporting base for the entire fixture, used to install and secure other functional mechanisms, thus providing a stable installation reference for each mechanism. The support mechanism 20 can be a bottom support assembly mounted on the workbench 10, used to lift the irregularly shaped glass 91 from below during assembly, thereby sharing the weight of the irregularly shaped glass 91 and maintaining its height position. The pre-positioning mechanism 30 can be a limiting assembly including multiple fixed first positioning elements, the area enclosed by the first positioning elements being larger than the orthographic projection of the irregularly shaped glass 91 on the horizontal plane, thus providing ample initial guiding space when the irregularly shaped glass 91 is placed in, reducing loading difficulty. The main positioning mechanism 40 can be a clamping assembly including multiple horizontally movable second positioning elements 41.

[0049] refer to Figure 6 The first accessory assembly mechanism 50 can be an accessory mounting assembly including a first receiving groove 51. The first receiving groove 51 is used to place the first accessory, and the mechanism can move up and down relative to the irregularly shaped glass 91. In this way, the first accessory can be abutted against the surface of the irregularly shaped glass 91 through vertical movement to complete the assembly. The above-mentioned mechanisms work together to improve the positioning reliability and assembly stability of the accessories during the installation process of the irregularly shaped glass 91.

[0050] Figure 2 This is a schematic diagram of an irregularly shaped glass 91 after the attachment is installed in a specific embodiment. It can be understood that irregularly shaped glass 91 of other shapes can also use the irregularly shaped glass attachment installation fixture of this application embodiment.

[0051] Specifically, the workbench 10 can be a platform welded from rectangular steel plates, with its upper surface machined to ensure flatness. The support mechanism 20 can include a cylinder-driven lifting plate, with multiple support heads spaced apart on the lifting plate. The top of each support head can have a structure to reduce damage to the irregularly shaped glass 91. The first positioning element of the pre-positioning mechanism 30 can be a rectangular block fixed to the workbench 10, with the inner side of the rectangular block forming the limiting surface of the irregularly shaped glass 91. The first accessory assembly mechanism 50 can include a lifting cylinder and a mounting base. The top surface of the mounting base has a contour groove that matches the outer contour of the nail post 92. The lifting cylinder drives the mounting base to move upward, causing the nail post 92 to abut against the assembly area on the lower surface of the irregularly shaped glass 91.

[0052] More specifically, the assembly of the nail post 92 and the irregularly shaped glass 91 can be by adhesive bonding, and the assembly area can be an adhesive application area. The nail post 92 includes an interconnected nail post body and an adhesive part, the adhesive part being used to bond to the irregularly shaped glass. The nail post body is a columnar body perpendicular to the plane of the irregularly shaped glass, and the contour groove opened on the top surface of the mounting base is machined according to the shape of the outer contour of the nail post body.

[0053] The irregular glass accessory installation fixture of this application embodiment initially defines the horizontal position of the irregular glass 91 from all sides through the pre-positioning mechanism 30, and then the second positioning member 41, which can move horizontally in the main positioning mechanism 40, clamps the irregular glass 91 from the side, realizing precise clamping and limiting of the irregular glass 91 in the horizontal direction. At the same time, the first accessory assembly mechanism 50 carries the accessory through the first receiving groove 51 and moves up and down relative to the irregular glass 91 to complete the abutment assembly. The overall structure works together to effectively improve the positioning reliability and assembly stability of the irregular glass 91 accessory installation process.

[0054] In some other embodiments of this application, the second positioning member 41 includes a clamping post 411 that clamps the irregular glass 91 from the side in the horizontal direction. The surface of the clamping post 411 that contacts the irregular glass 91 is provided with a positioning groove 412. The width of the positioning groove 412 in the vertical direction is adapted to the thickness of the irregular glass 91.

[0055] Without limitation, the second positioning member 41 includes a clamping post 411, and a positioning groove 412 is formed on the surface of the clamping post 411. The width of the positioning groove 412 in the vertical direction is adapted to the thickness of the irregular glass 91. In this way, the positioning reliability of the irregular glass 91 in the horizontal direction can be improved through the dual effects of side clamping and groove wall limiting.

[0056] Specifically, the second positioning element 41 may include a horizontal cylinder and a clamping column 411. The clamping column 411 may be a cylindrical metal part with a positioning groove 412 circumferentially opened on its side.

[0057] For example, when the operator places the irregularly shaped glass 91 on the support mechanism 20, the irregularly shaped glass 91 first falls into the area enclosed by the four rectangular blocks of the prepositioning mechanism 30 and is supported from the bottom by the support mechanism 20, completing the rough positioning; then the four horizontal cylinders of the main positioning mechanism 40 act synchronously, driving the clamping column 411 to move from the periphery of the irregularly shaped glass 91 towards the center, the positioning groove 412 on the clamping column 411 is engaged with the edge of the irregularly shaped glass 91, the bottom of the groove is in contact with the side of the irregularly shaped glass 91, and the upper edge of the groove is flush with the upper surface of the irregularly shaped glass 91, achieving precise clamping; then the lifting cylinder of the first accessory assembly mechanism 50 is activated, driving the mounting base and the nail column 92 in the first receiving groove 51 to move upward, the top of the nail column 92 presses against the preset adhesive application position on the lower surface of the irregularly shaped glass 91, and holds for a certain period of time until the adhesive is initially cured, completing the assembly operation of the nail column 92.

[0058] Furthermore, the edge of the positioning groove 412 of the clamping column 411 can be chamfered or rounded to guide the edge of the irregular glass 91 smoothly into the positioning groove 412 during the clamping process, reducing the risk of jamming and reducing the probability of the sharp edge of the groove scratching the surface of the irregular glass 91.

[0059] In other embodiments of this application, reference is made to Figure 1 and Figure 3 The support mechanism 20 includes a plurality of support members spaced apart. Each support member includes a support body 21 and a support drive member 22. The support body 21 can be lifted or lowered under the drive of the support drive member 22.

[0060] Without limitation, the support member can be the smallest functional unit of the support mechanism 20. Multiple support members spaced apart can adapt to the irregular bottom contour of the irregular glass 91, thus providing a uniformly distributed support force. The support body 21 can be a supporting component that directly contacts the irregular glass 91, thus transmitting the power of the support drive 22. The support drive 22 can be a power source that provides linear reciprocating motion to drive the support body 21 to rise and fall, thus adjusting the support height to adapt to different working conditions. The lifting or lowering action of the support body 21 enables flexible switching between raising the irregular glass 91 for easy operation during loading and lowering it during assembly to make way for suction cups or other mechanisms.

[0061] Specifically, the number of support members can be three to six, arranged according to the area and weight distribution of the irregularly shaped glass 91. The support drive member 22 can be a double-acting cylinder or an electric actuator, with precise stroke control achieved through a solenoid valve or motor controller.

[0062] For example, during the loading stage, all support drive components 22 extend synchronously, lifting the support body 21 to its highest position. The operator then places the irregularly shaped glass 91 smoothly onto the ball bearings at the top of the multiple support bodies 21. After positioning, the support drive components 22 retract synchronously, and the support body 21 falls back to its lowest position. At this time, the irregularly shaped glass 91 is picked up by the vacuum suction cup 61, and the support body 21 is completely detached from the bottom surface of the irregularly shaped glass 91, thus creating clearance space for the subsequent lifting and assembly of the nail column 92.

[0063] Furthermore, the top ball bearing of the support body 21 can adopt an embedded installation structure, that is, a spherical groove is opened on the top of the support body 21, the ball bearing is embedded in the groove and limited by the pressure ring. This not only ensures the flexibility of the ball bearing's universal rotation, but also reduces the risk of the ball bearing falling off, and improves the long-term operational reliability of the support mechanism 20.

[0064] In some other embodiments of this application, the top of the support 21 includes a metal pillar with omnidirectional balls.

[0065] Unrestricted, the omnidirectional ball bearing can be a spherical rolling element, positioned at the top of the support 21 and protruding from the support surface. This converts the sliding friction between the irregularly shaped glass 91 and the support 21 into rolling friction. Omnidirectional means the ball bearing can rotate freely in any direction, accommodating minor angular deviations when the irregularly shaped glass 91 is placed, reducing resistance and the risk of scratches during positioning. The protruding design of the ball bearing ensures that only the apex of the ball bearing contacts the irregularly shaped glass 91, minimizing the contact area and reducing the probability of contamination and damage.

[0066] For example, when the irregularly shaped glass 91 is placed on the support 21, the bottom surface of the irregularly shaped glass 91 contacts the apex of multiple balls. If the irregularly shaped glass 91 is slightly warped or the placement angle is skewed, each ball can adaptively adjust its rotation direction so that the irregularly shaped glass 91 can smoothly slide into the limiting range of the pre-positioning mechanism 30 without causing the edge of the irregularly shaped glass 91 to chip or the surface to be scratched due to local jamming.

[0067] Furthermore, the ball surface can be polished or coated with a wear-resistant coating, which can further reduce the coefficient of friction and extend the service life, while reducing the defects of irregular glass 91 micro-scratches caused by the roughness of the ball surface.

[0068] In other embodiments of this application, reference is made to Figure 1 and Figure 4 The first positioning component includes a column 31 and a positioning boss 32. The bottom end of the column 31 is fixed to the worktable 10. The positioning boss 32 is formed by protruding from the upper end of the column 31 toward the irregular glass 91. The end of the positioning boss 32 facing the irregular glass 91 includes a positioning plane.

[0069] Unrestricted, the column 31 can be the vertical support portion of the first positioning member, used to raise the positioning boss 32 to a height corresponding to the edge of the irregularly shaped glass 91, thus avoiding interference between the positioning structure and other components on the worktable 10. The positioning boss 32 can be a protruding structure extending laterally from the upper end of the column 31, used to provide an actual limiting contact surface, thus accurately setting the limiting action point in the edge area of ​​the irregularly shaped glass 91. The positioning plane can be a flat surface on the positioning boss 32 that directly contacts the edge of the irregularly shaped glass 91, thus providing a stable normal constraint force. The integrated structure of the column 31 and the positioning boss 32 improves the overall rigidity and positional accuracy of the first positioning member. It should be noted that, limited by the projection angle of the attached drawings, the first positioning member is in... Figure 1 There is only one of them; in fact, there are sets around all four sides of the irregularly shaped glass 91.

[0070] Specifically, the column 31 can be a cylindrical or square cross-section metal rod, fixed to the worktable 10 by threaded connection or welding. The positioning boss 32 can be a rectangular block structure, extending horizontally from the top of the column 31. The positioning plane can be a vertical plane that has been ground, with a flatness error controlled within 0.05 mm.

[0071] Furthermore, a buffer pad made of polyurethane or rubber can be attached to the positioning plane. This can absorb impact energy when the irregular glass 91 comes into contact with the positioning plane, reducing the risk of edge breakage of the irregular glass 91. At the same time, the elastic deformation of the pad can compensate for the dimensional tolerance of the irregular glass 91 and improve the adaptability of the pre-positioning.

[0072] In other embodiments of this application, reference is made to Figure 1 and Figure 5 The longitudinal cross-sectional shape of the positioning groove 412 is a trapezoid with the groove opening larger than the groove bottom, and the thickness of the irregular glass 91 is between the dimensions of the groove bottom and the groove opening.

[0073] Unrestricted, the longitudinal cross-sectional shape of the positioning groove 412 is trapezoidal, with the groove opening larger than the bottom, thus creating a guide space that gradually narrows from top to bottom. The thickness of the irregularly shaped glass 91 is between the dimensions of the groove bottom and the groove opening, allowing the edge of the irregularly shaped glass 91 to be in a floating, centered state within the groove, preserving necessary clamping allowance while avoiding stress concentration caused by interference fit. The inclined guiding effect of the trapezoidal groove automatically corrects the vertical positional deviation of the irregularly shaped glass 91 during clamping, improving positioning consistency.

[0074] Specifically, the bottom width of the trapezoidal groove can be equal to the nominal thickness of the irregularly shaped glass 91, and the groove opening width can be 0.5 mm to 2 mm wider than the bottom width. The included angle of the two inclined surfaces of the trapezoidal groove can be 60° to 90°. The groove depth can be 5 mm to 15 mm, sufficient to cover the effective clamping area of ​​the edge of the irregularly shaped glass 91. The trapezoidal groove can be formed on the side of the clamping post 411 by wire cutting or milling.

[0075] For example, when the clamping column 411 moves horizontally closer to the irregular glass 91, the edge of the irregular glass 91 first enters the wider groove area of ​​the trapezoidal groove. As the clamping column 411 continues to advance, the inclined surface of the groove wall guides the edge of the irregular glass 91 to slide towards the bottom of the groove until the side of the irregular glass 91 is in contact with the bottom of the groove and the upper surface of the irregular glass 91 is flush with the upper edge of the groove. At this time, the irregular glass 91 is constrained in both the vertical and horizontal directions, and the precise positioning is completed.

[0076] Furthermore, a rounded transition can be provided at the junction of the bottom of the trapezoidal groove and the inclined surface. This can eliminate stress concentration at sharp corners, reduce the risk of micro-cracks in the edge of the irregular glass 91 due to local compression during clamping, and at the same time, the rounded transition is also conducive to the smooth movement of the machining tool and improves the machining quality of the groove.

[0077] In other embodiments of this application, a plurality of second positioning members 41 are spaced apart along the length direction of the irregular glass 91.

[0078] Unrestricted, multiple second positioning elements 41 are spaced apart along the length direction, which provides multi-point clamping force on the long side of the irregularly shaped glass 91, improving the uniformity of the clamping force. This spaced-out layout can accommodate potential curvature changes or local protrusions on the long side of the irregularly shaped glass 91, avoiding deformation or positioning instability caused by single-point clamping. The synergistic effect of the multiple second positioning elements 41 improves the torsional stiffness of the irregularly shaped glass 91 along its length, enhancing overall stability during assembly.

[0079] Specifically, the number of second positioning elements 41 can be two to four on each side, depending on the length of the irregularly shaped glass 91. The horizontal drive of each second positioning element 41 of the irregularly shaped glass 91 can be controlled independently or synchronously, depending on the actual clamping strategy.

[0080] Furthermore, the second positioning members 41 located at both ends of the irregular glass 91 along its length can be configured as adjustable structures, i.e., installed via slide rails or waist-shaped holes. This allows for fine-tuning of the positions of the clamping points at both ends according to the actual length of the irregular glass 91, thereby improving the compatibility of the tooling with irregular glass 91 of different lengths.

[0081] In some other embodiments of this application, the first accessory is a nail post 92, and the first receiving groove 51 is a contour groove that matches the outer contour shape of the nail post 92.

[0082] Without limitation, the first accessory is a stud 92, which is a fastener used to connect the irregularly shaped glass 91 to the vehicle body or other components, thus clarifying the functional attributes of the accessory. The first receiving groove 51 is a contour groove, meaning that the shape of the inner cavity of the groove matches the outer contour of the stud 92, which can circumferentially limit the stud 92 and prevent it from tilting or rotating during assembly. The shape matching relationship between the contour groove and the stud 92 ensures that the stud 92 is lifted onto the surface of the irregularly shaped glass 91 in the correct posture, improving the accuracy of the bonding position.

[0083] Furthermore, a through-hole for ejector pins can be opened at the bottom of the contour groove, penetrating the mounting base. A position detection probe or an auxiliary ejector rod can be inserted into the through-hole for detecting whether the pin 92 is correctly positioned before assembly, and for assisting the pin 92 in demolding or re-checking its position after assembly, thereby improving the automation level and quality control capability of the assembly process.

[0084] In other embodiments of this application, reference is made to Figure 1 and Figure 7 The tooling also includes:

[0085] A glass driving component 60 is disposed on the worktable 10 and configured to drive the irregularly shaped glass 91 to descend after the irregularly shaped glass 91 is positioned by the main positioning mechanism 40, so as to cooperate with the assembly work of the first accessory assembly mechanism 50; the glass driving component 60 includes a vacuum suction cup 61, through which the irregularly shaped glass 91 is adsorbed onto the glass driving component 60.

[0086] Unrestricted, the glass drive unit 60 can be a vertical motion component mounted on the worktable 10, used to actively drive the irregularly shaped glass 91 downwards after the main positioning is completed. This creates suitable assembly space and pressure conditions for the first accessory assembly mechanism 50. The vacuum suction cup 61 can be an actuator that uses the principle of negative pressure adsorption to grasp the irregularly shaped glass 91, thus achieving reliable gripping without damaging the surface of the irregularly shaped glass 91. The combination of the vacuum suction cup 61 and the glass drive unit 60 enables non-destructive lifting and precise positioning of the irregularly shaped glass 91, coordinating with accessory assembly actions. The timing of the downward movement of the irregularly shaped glass 91 ensures that the irregularly shaped glass 91 is in a controlled and stable state during accessory assembly.

[0087] Specifically, the glass driving component 60 may include a first cylinder 62 as a lifting power source. The vacuum suction cup 61 may be a flat-bottomed suction cup made of silicone or polyurethane, and the number of suction cups may be four to eight, evenly distributed above the irregularly shaped glass 91. The vacuum suction cup 61 is independently controlled by an electromagnetic valve assembly, enabling zoned adsorption to adapt to different areas of the irregularly shaped glass 91. The descent speed of the irregularly shaped glass 91 is adjustable to avoid impact.

[0088] For example, after the main positioning mechanism 40 completes clamping, the vacuum suction cup 61 of the glass drive component 60 is energized to generate negative pressure, adsorbing the upper surface of the irregular glass 91; then the clamping column 411 of the main positioning mechanism 40 is released, and the glass drive component 60 drives the irregular glass 91 to descend, so that the lower surface of the irregular glass 91 approaches the top of the nail column 92 of the first accessory assembly mechanism 50; then the first accessory assembly mechanism 50 is lifted, and the nail column 92 presses against the lower surface of the irregular glass 91 to complete the bonding; after the assembly is completed, the glass drive component 60 rises again to reset, and the main positioning mechanism 40 clamps again, ready for the next process.

[0089] Furthermore, the adsorption surface of the vacuum suction cup 61 can be provided with an annular sealing groove and an elastic sealing ring can be embedded. This can maintain good sealing performance even when there are slight undulations or textures on the surface of the irregular glass 91, reduce the risk of adsorption failure caused by air leakage, and improve the working reliability of the glass drive component 60.

[0090] In other embodiments of this application, reference is made to Figure 1 and Figure 8 The tooling also includes:

[0091] The second accessory assembly mechanism 70 is disposed on the workbench 10 and includes a second receiving groove 71 for placing the second accessory; the second accessory assembly mechanism 70 can assemble the second accessory in the second receiving groove 71 into the irregular glass 91 when the irregular glass 91 is lowered.

[0092] Unrestricted, the second accessory assembly mechanism 70 can be a functional module for installing second-type accessories such as the edge banding strip 93, thus expanding the tooling's assembly capabilities and enabling integrated installation of multiple accessories. The second receiving slot 71 of the second accessory assembly mechanism 70 is used to hold the second accessory, allowing for pre-positioning of the second accessory's assembly posture. The second accessory assembly mechanism 70 completes assembly synchronously with the descent of the irregularly shaped glass 91, utilizing the kinetic energy or displacement of the descending glass 91 to trigger the assembly action, simplifying the drive logic. The parallel assembly capability of the second accessory and the first accessory shortens the assembly cycle time of a single product, improving production efficiency.

[0093] Specifically, the second accessory can be an edge banding strip 93, used to wrap the edge of the irregularly shaped glass 91. The second receiving groove of the second accessory assembly mechanism 70 can be a contour-fitting limiting groove that matches the cross-section of the edge banding strip 93. The second accessory assembly mechanism 70 can be fixed to one side of the irregularly shaped glass 91. When the irregularly shaped glass 91 descends to a specific height, the bottom of the edge of the irregularly shaped glass 91 abuts against the edge banding strip 93, and the wrapping assembly is completed by the weight of the irregularly shaped glass 91 itself or by auxiliary pressure.

[0094] Understandably, even without the glass driving component 60, the first accessory can be assembled onto the irregularly shaped glass simply by the up-and-down movement of the first accessory assembly mechanism. However, including the glass driving component 60 allows for more adjustment options in the entire assembly, making the assembly more precise and stable. Furthermore, it facilitates the assembly of the second accessory or other accessories.

[0095] For example, the edge banding strip 93 is a three-sided wrapped rubber strip, which is pre-placed in the contour limiting groove of the second accessory assembly mechanism 70 and fixed by vacuum adsorption; after the main positioning is completed, the irregular glass 91 is driven down by the glass drive member 60. When the edge of the irregular glass 91 drops to the height aligned with the edge banding strip 93, the edge of the irregular glass 91 is inserted into the U-shaped opening of the edge banding strip 93; then the irregular glass 91 continues to drop a small distance, so that the edge banding strip 93 tightly wraps the edge of the irregular glass 91, and the assembly of the second accessory is completed.

[0096] Furthermore, the second receiving groove sidewall of the second accessory assembly mechanism 70 can be provided with a clearance notch facing the assembly position of the irregular glass 91. This can prevent the groove wall from interfering with the irregular glass 91 or other mechanisms when the edge banding strip 93 covers the edge of the irregular glass 91. This is especially suitable for assembly scenarios with complex shapes such as edge banding strips with three or four sides, thereby improving the assembly success rate.

[0097] In other embodiments of this application, reference is made to Figure 1 and Figure 9 The tooling also includes:

[0098] A clamping mechanism 80 is disposed on the worktable 10 and configured to clamp the irregular glass 91 from the top after the irregular glass 91 is lowered, so as to cooperate with the assembly of the first accessory.

[0099] Unrestricted, the clamping mechanism 80 can be a vertical pressure-applying component positioned above the worktable 10, used to apply downward pressure from the top after the irregularly shaped glass 91 has descended into place. This counteracts the upward reaction force exerted on the irregularly shaped glass 91 during the lifting of the first accessory. The clamping action of the clamping mechanism 80 occurs after the irregularly shaped glass 91 has descended, ensuring that the clamping force acts on the already positioned irregularly shaped glass 91 and avoiding premature clamping that could interfere with the positioning process. The cooperation between the clamping mechanism 80 and the first accessory assembly mechanism 50 maintains the stability of the irregularly shaped glass 91's posture during assembly, improving the bonding quality of the adhesive interface.

[0100] Specifically, the clamping mechanism 80 may include a second cylinder 81 and a pressure head 82. The bottom surface of the pressure head 82 may be a flat surface or a contoured curved surface, matching the shape of the upper surface of the irregularly shaped glass 91. The action of the clamping mechanism 80 may be triggered by a sensor and will automatically start after the signal confirming that the irregularly shaped glass 91 has descended into place is received.

[0101] For example, after the glass drive unit 60 lowers the irregular glass 91 to the assembly station, the pressure head 82 of the clamping mechanism 80 is quickly pressed down under the drive of the second cylinder 81 to press the upper surface of the irregular glass 91; then the first accessory assembly mechanism 50 is lifted, and the nail post 92 presses against the lower surface of the irregular glass 91; the forces on the upper and lower sides are balanced with each other, and the irregular glass 91 has no vertical displacement during the assembly process. The nail post 92 and the adhesive surface of the irregular glass 91 maintain a constant pressure until the adhesive is initially cured.

[0102] Furthermore, a silicone or polyurethane buffer layer can be attached to the bottom surface of the pressure head 82. This can distribute the pressure evenly during pressing, preventing the rigid pressure head 82 from leaving indentations on the surface of the irregular glass 91 or causing excessive local stress. At the same time, the elastic deformation of the buffer layer can adapt to the slight undulations on the surface of the irregular glass 91, improving the uniformity of the pressing effect.

[0103] In some other embodiments of this application, the tooling further includes an automatic control unit (not shown), which is electrically connected to the support mechanism 20, the pre-positioning mechanism 30, the main positioning mechanism 40, the first accessory assembly mechanism 50, the glass drive component 60, the second accessory assembly mechanism 70, and the clamping mechanism 80, and is configured to coordinate the action sequence of each mechanism according to a preset timing sequence.

[0104] An automatic control unit, which can be a programmable logic controller (PLC) or an industrial computer, receives sensor signals and outputs control commands. The preset timing sequence can be program logic stored within the automatic control unit, defining the order in which various mechanisms start, stop, and operate. The electrical connections between mechanisms can be achieved through bus communication or hardwiring for signal transmission. The introduction of an automatic control unit integrates previously scattered manual operations into an automated process, reducing the uncertainty caused by human intervention and improving assembly consistency and production cycle stability.

[0105] Specifically, the automatic control unit can collect position sensor signals from the support mechanism 20, pressure sensor signals from the vacuum suction cup 61, and position sensor signals from the clamping mechanism 80, and adjust the action parameters of each actuator in real time based on this feedback.

[0106] For example, the initial state of the tooling and the tooling operation process are described below:

[0107] Initial state of the tooling: the prepositioning mechanism 30 remains fixed in its normal position; the main positioning mechanism 40 is in the open state; the clamping mechanism 80 is not applying pressure and remains open; the glass drive component 60 is in the lowered position; the support mechanism 20 is lifted into place; the first accessory assembly mechanism 50 is lowered and reset, and accessory assembly is not performed for the time being; the second accessory assembly mechanism 70 is fixed throughout the process and has no movement.

[0108] Tooling operation process: First, place the first accessory, i.e., the nail post 92, into the contour groove of the first accessory assembly mechanism 50, and place the second accessory (edge ​​trim 93) into the contour groove of the second accessory assembly mechanism 70; then, place the irregularly shaped glass 91 into the pre-positioning area of ​​the pre-positioning mechanism 30 and drop it onto the support mechanism 20. Subsequently, the operator presses the start button, and the following is automatic operation: the main positioning mechanism 40 clamps and fixes the glass, and the glass driving component 60 lifts and adsorbs the glass; then the support mechanism 20 falls back and the main positioning mechanism 40 retracts. The glass driving component 60 drives the glass to descend, placing the irregularly shaped glass 91 onto the contour groove of the second accessory assembly mechanism 70, where the clamping mechanism 80 applies pressure, and at the same time, the first accessory assembly mechanism 50 lifts to complete the assembly of the nail post 92. After the nail column 92 is installed, the first accessory assembly mechanism 50 falls back to its original position, the clamping mechanism 80 is released; the glass drive component 60 rises, the support mechanism 20 is lifted into place, the suction cup descends again, the tooling returns to its initial standby state, the single-wheel accessory assembly process is completed, and it waits for the next round.

[0109] Furthermore, the automatic control unit can be equipped with a human-machine interface to display the current process status, alarm information and process parameter settings, which facilitates monitoring and debugging by operators. It also supports formula management functions and can store assembly programs for various irregularly shaped glass 91s to achieve rapid changeover.
