Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a flexible support worktable. Background Technology

[0002] In the production and processing of bus window glass, the glass needs to be fixed in place before corresponding connectors are installed or processed around it. Therefore, a flexible worktable is needed to fix and position the glass, facilitating window installation and production. Because there are increasingly more bus models today, there are also increasingly more bus glass models. These different models have different sizes, structures, and curvatures. Previously, it was often necessary to design and manufacture specific worktables for each type of product. This approach resulted in high glass processing costs, and the idle worktables also occupied space.

[0003] For example, Chinese utility model patent CN221500909U discloses a fixing fixture for glass processing. This fixture includes a frame with a horizontally positioned support platform on the frame. Several guide grooves are provided on the support platform, and several limiting blocks are spaced apart at the edges of the guide groove openings. Limiting elements are threadedly connected to the limiting blocks, and a first fixing component is slidably connected within the guide grooves. The first fixing component includes a first support column and a stabilizing block. The stabilizing block is disposed within the guide groove. A first vacuum suction cup is provided on the side of the first support column opposite to the stabilizing block. The first support column has threaded holes that can be threadedly connected to the limiting elements, allowing the first support column to be adjusted at different limiting blocks. Several auxiliary support components are also provided on the support platform. These auxiliary support components can provide auxiliary support for different positions of the glass through elastic floating. Each auxiliary support component includes a fixed column fixed to the support platform, with a sliding cavity formed within the fixed column. A second support column is slidably connected within the sliding cavity, and a spring is provided between the second support column and the sliding cavity, allowing the second support column to float elastically. The glass is fixed by adsorbing and limiting the front and back sides of the glass on opposite sides in the vertical direction using the first and second fixing components. This ensures the strong connection of the glass on the glass processing fixture and allows the fixture to adapt to different sizes of glass due to the mobility of the first fixing component, giving the glass processing fixture good applicability.

[0004] In the aforementioned prior art, the auxiliary support component is fixed in the central area of ​​the support platform, and the first fixing component is located on the periphery of the area where the auxiliary support component is located. The height of the first fixing component is fixed, which results in a large height difference between the two ends and the middle of the glass when processing glass with a certain curvature. This causes different first fixing components to be unable to adsorb and fix both ends and the middle of the glass, resulting in poor adsorption and fixing effect. Utility Model Content

[0005] The purpose of this invention is to provide a flexible support worktable to solve the problem that in the prior art, the adsorption components cannot stably adsorb and fix both ends and the middle of curved glass, resulting in poor adsorption and fixing effect on the glass.

[0006] To solve the above problems, the flexible support worktable of this utility model adopts the following technical solution:

[0007] A flexible support worktable includes a support surface. The support surface is provided with at least one vacuum suction cup for adsorbing and fixing a plate-shaped workpiece. The support surface is also provided with multiple elastic legs for supporting the plate-shaped workpiece from below and upward. The vacuum suction cups are clustered in the middle area of ​​the support surface to adsorb and fix the plate-shaped workpiece from the middle position. The elastic legs are adjustablely mounted on the support surface and dispersed around the vacuum suction cups to cooperate with the vacuum suction cups to provide multi-point support for the plate-shaped workpiece.

[0008] Furthermore, the support platform is provided with a plurality of elongated adjustment mounting slots, which are evenly spaced in the width direction of the support platform. The elastic support leg can be adjusted in position along the adjustment mounting slot by assembling with the adjustment mounting slot.

[0009] Furthermore, the support platform is a T-slot platform, and the T-slots on the T-slot platform constitute the adjustment and installation slots.

[0010] Furthermore, the bottom of the elastic outrigger has a connecting seat, the connecting seat is provided with an outrigger bolt hole for the bolt to pass through, the head of the bolt is located in the T-slot, and the shank of the bolt passes through the outrigger bolt hole from bottom to top and cooperates with the nut to lock and fix the elastic outrigger in the required position.

[0011] Furthermore, the position of the vacuum suction cup on the support platform is adjustable.

[0012] Furthermore, the support platform is provided with multiple clearance holes to allow the vacuum suction cup to pass through from top to bottom, and the vacuum suction cup can be installed at different clearance holes to achieve position adjustment.

[0013] Furthermore, the vacuum suction cup includes a hollow support rod, which is used to be inserted into the clearance hole. A limit plate is provided on the outer side of the hollow support rod. The limit plate has suction cup bolt holes. The limit plate is locked and fixed to the support platform by bolts whose heads are in the adjustment and mounting groove and pass through the suction cup bolt holes.

[0014] Furthermore, the clearance holes are arranged at intervals along the moving direction of the elastic support leg.

[0015] Furthermore, the top of the elastic support leg is provided with a rubber cap to avoid impacts.

[0016] Furthermore, the rubber cap is a spherical cap.

[0017] This invention, a flexible support worktable, is a pioneering creation. When processing plate-shaped workpieces with a certain curvature, the vacuum suction cups converge in the central area of ​​the support table, effectively adsorbing and fixing the workpiece in this central region. Due to the clustered arrangement of the vacuum suction cups, the adsorption area for the corresponding plate-shaped workpiece is within a certain range, ensuring a stable and reliable adsorption and fixation. Elastic legs are distributed around the vacuum suction cups, and their position relative to the support table is adjustable. This allows for adjustment of the elastic legs' position according to different shapes and specifications of plate-shaped workpieces, providing relatively dispersed and uniform support to the outer perimeter. The elastic floating capability of the legs can adapt to height differences in the plate-shaped workpiece, thus providing stable elastic support to the outer area. Together with the vacuum suction cups, this provides stable and reliable adsorption, fixation, and multi-point support for curved plate-shaped workpieces. Attached Figure Description

Plate-shaped workpiece. Detailed Implementation

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] This invention addresses the problems of existing technologies by placing a vacuum suction cup of the flexible support worktable in the middle of the support surface to adsorb and fix the plate-shaped workpiece in the middle region. Several elastic legs are arranged around the vacuum suction cup on the support surface. These elastic legs have elastic floating capabilities, thus providing elastic support to the outer regions of the plate-shaped workpiece that have different heights from the middle region, improving the stability of the support. Furthermore, the elastic legs are adjustable relative to the support surface, allowing them to be adjusted to accommodate plate-shaped workpieces of different sizes, thereby expanding the applicability of the flexible support worktable.

[0026] Based on the main concepts above, different implementation methods are provided below for illustration.

[0027] In a typical implementation, refer to Figure 1-5 As shown, the flexible support worktable includes a base 40 made of profiles. A support platform 10 is provided on the upper surface of the base 40. The support platform 10 is a T-slot platform with multiple parallel T-slots spaced apart. One or more vacuum suction cups 20 are provided on the support platform 10. The vacuum suction cups 20 are used to adsorb one side of the plate-shaped workpiece 5. Several clearance holes 111 are provided in one of the T-slots, spaced apart along the length of the T-slot. The vacuum suction cups 20 are installed at the clearance holes 111. Selecting different clearance holes allows for adjustment of the vacuum suction cups 20 to different positions, giving them a certain degree of positional adjustment capability and enhancing their mobility. The vacuum suction cups 20 are located in the central area of ​​the support platform 10 for adsorbing and fixing the central position of the plate-shaped workpiece. The rubber nozzles 21 of the vacuum suction cups 20 have a certain deformation, allowing them to be pressed down by the plate-shaped workpiece 5 within a certain range of motion.

[0028] Multiple elastic legs 30 are provided on the support platform 10. A connecting seat 34 is provided at the bottom of each elastic leg 30. The connecting seat 34 has bolt holes 341 for easy bolt passage from bottom to top. The multiple elastic legs 30 can elastically float relative to the support platform 10 in the vertical direction, thus providing elastic support for plate-shaped workpieces. The vacuum suction cup 20 can adjust its position relative to the support platform 10 through multiple clearance holes 111. The multiple elastic legs 30 can move relative to the support platform 10, thereby enhancing the flexible support worktable's ability to match plate-shaped workpieces of different sizes and curvatures, and expanding the applicability of the flexible support worktable.

[0029] refer to Figure 2 The vacuum suction cup 20 includes a hollow support rod 22. A rubber suction nozzle 21 for contacting the plate-shaped workpiece is located at the top of the hollow support rod 22. A limiting plate 23 is provided on the outer circumferential surface of the hollow support rod 22. The limiting plate 23 abuts against the T-slot platform. By inserting the hollow support rod 22 into the clearance hole and the limiting plate 23 fitting against the support platform, the position of the hollow support rod 22 can be restricted, preventing it from shaking. The head of the bolt is located within the T-slot, and the bolt shank passes through the support leg bolt hole from bottom to top and engages with the nut to lock the elastic support leg in the desired position. This allows the limiting plate 23 to be fixed relative to the T-slot by the bolt, preventing the vacuum suction cup 20 from being pulled out by the plate-shaped workpiece when it needs to be removed. The hollow support rod 22 extends through the clearance hole 111 to the back of the support table 10 and is connected to the vacuum system's suction pipe, thereby enabling the vacuum suction cup 20 to draw a vacuum, which increases the negative pressure between the rubber suction cup 21 and the plate-shaped workpiece, enhances the vacuum suction cup 20's ability to adsorb and fix the plate-shaped workpiece, and improves the flexible support table's fixation firmness and stability for the plate-shaped workpiece.

[0030] refer to Figure 4The elastic support leg 30 includes a support column 31, a sliding hole 311 within the support column 31, and a support rod 32 within the sliding hole 311. A spring 35 is installed at the bottom of the support rod 32 within the sliding hole 311. The lower end of the spring 35 abuts against the bottom of the sliding hole 311, and the upper end abuts against the bottom of the support rod 32, providing elastic force to the support rod 32, thereby enabling the elastic support leg 30 to float elastically. When fixing and positioning irregular, large, or curved plate-shaped workpieces, the elastic support leg 30 can move relative to the support table 10, thus improving its ability to provide auxiliary support for plate-shaped workpieces of different sizes, thereby enhancing the applicability of the flexible support worktable. A spherical rubber cap 33 is fitted onto the top of the support column 31 of the elastic support leg 30. The rubber cap 33 itself has a certain elastic deformation capability, so when in contact with the plate-shaped workpiece, it can protect the surface of the plate-shaped workpiece and prevent scratches. Meanwhile, the spherical rubber cap 33 further enhances its safety. A connecting seat 34 is provided at the bottom of the support column 31. The connecting seat 34 is designed to fit against the support platform 10 and can slide along the support platform 10 to allow for adjustment of the elastic support leg 30 relative to the support platform 10. A support leg bolt hole 341 is provided on the connecting seat 34. The bolt head is positioned within a T-slot, allowing the bolt to pass through the bolt hole 341 from bottom to top and connect with a nut. This ensures that the elastic support leg 30 connected to the bolt is locked and fixed to the support platform, preventing the elastic support leg 30 from tilting or detaching relative to the support platform 10. When the nut is loosened, the bolt head can slide relative to the T-slot within the T-slot, allowing the connecting seat 34 to move relative to the support platform 10, thereby expanding the range of motion and mobility of the elastic support leg 30 and improving the adjustability of the flexible support worktable.

[0031] In summary, the vacuum suction cup 20 can change position relative to the supporting table 10, and the elastic leg 30 can be adjusted in position relative to the supporting table 10. Therefore, due to the large range of motion of the vacuum suction cup 20 and the elastic leg 30, they can be applied to various plate-shaped workpieces with different structures, sizes, or curvatures. This improves the applicability of the flexible support worktable and enhances its suitability. It eliminates the need for specially designed and manufactured positioning worktables for different sizes and models of plate-shaped workpieces, saving costs. The vacuum suction cup 20 is positioned in the central area of ​​the supporting table 10, allowing it to adsorb, fix, and support the central area of ​​the plate-shaped workpiece. The elastic leg 30 is positioned on the table surface surrounding the vacuum suction cup 20, supporting the outer edge of the plate-shaped workpiece. Together, the elastic leg 30 and the vacuum suction cup 20 can achieve multi-point support for the plate-shaped workpiece. Meanwhile, when processing plate-shaped workpieces with a certain curvature, due to the positioning of the aforementioned elastic support legs 30 and vacuum suction cups 20, the plate-shaped workpieces in the middle area with a small height difference are attracted, fixed, and supported by the vacuum suction cups with a fixed height. In the outer edge area with a large height difference, the plate-shaped workpieces are supported by the elastic support legs 30 with a certain elastic floating capability. This ensures that during the processing of the curved plate-shaped workpieces, the flexible support worktable effectively supports the outer edge area of ​​the plate-shaped workpieces, avoiding problems such as unstable attraction, fixation, and support of the plate-shaped workpieces.

[0032] In the above embodiments, by providing a plurality of clearance holes 111 arranged along the length of the T-slot, the vacuum suction cup 20 adjusts its position relative to the support table 10 by inserting into the clearance holes 111 at different positions. In another embodiment, the side of the vacuum suction cup 20 can be connected to the vacuum system, so that the bottom of the vacuum suction cup 20 no longer needs to pass through the support table 10. Therefore, a sliding block that can move relative to the T-slot can be provided at the bottom of the vacuum suction cup 20. The sliding block can be directly set in the T-slot, so that the sliding block slides with the T-slot. Alternatively, a suction cup bolt through hole 231 can be provided on the sliding block of the vacuum suction cup 20. The bolt passes through the suction cup bolt through hole 231 from bottom to top and engages with the nut, so that the head of the bolt can slide relative to the T-slot, allowing the vacuum suction cup 20 to also move relative to the T-slot, thereby expanding the movement range of the vacuum suction cup 20 and improving the applicability of the flexible support worktable to plate-shaped workpieces of different sizes. Regardless of the implementation method, it is only necessary to ensure that the vacuum suction cup 20 is concentrated in the middle area of ​​the support platform 10 to adsorb and position the middle of the plate-shaped workpiece, or the specific position of the vacuum suction cup 20 can be adjusted adaptively according to different situations.

[0033] In another embodiment, the vacuum suction cup 20 is fixedly mounted on the support platform 10 and its relative position to the support platform 10 cannot be changed, but it is sufficient that the vacuum suction cup 20 is fixedly mounted in the middle area of ​​the support platform 10.

[0034] In the above embodiment, the support platform 10 is provided with a plurality of elongated adjustment and mounting grooves 11. The adjustment and mounting grooves 11 are T-shaped grooves with narrowed openings. The T-shaped grooves constitute the adjustment and mounting grooves 11. Therefore, the support platform 10 is a T-shaped groove platform. Thus, the support platform 10 limits the vacuum suction cup 20 and the elastic support leg 30 through the T-shaped grooves.

[0035] In embodiments where the support platform 10 is a T-slot platform, the support platform 10 is integrally formed, and the entire support platform 10 can be a single piece of T-slot platform. Or, as... Figure 2 As shown, the support platform 10 is composed of multiple T-slot platforms spliced ​​together. Therefore, when it is necessary to support and fix some large plate-shaped workpieces, multiple T-slot platforms can be spliced ​​and assembled into a support platform 10 corresponding to the plate-shaped workpiece. This can further improve the applicability of the flexible support worktable and expand its application range.

[0036] In another embodiment, the adjusting mounting groove 11 is an open through groove. The connecting seat 34 at the bottom of the elastic support leg 30 is directly disposed within the adjusting mounting groove 11 and slides into it to achieve the adjustment capability of the elastic support leg 30. The elastic support leg 30 is limited by the friction between the inner wall of the through groove and the side of the connecting seat, so that the elastic support leg 30 remains stable in the required position and avoids deviation of the elastic support leg 30 relative to the adjusting mounting groove 11. In the embodiment where the adjusting mounting groove 11 is a T-slot, the bottom connecting seat 34 of the elastic support leg 30 is provided with at least one support leg bolt through hole 341. The bolt passes through the support leg bolt through hole 341 from bottom to top and is connected to the nut. The head of the bolt is located in the T-slot and is limited by the T-slot, so that the head of the bolt slides in the T-slot. The bottom of the connecting seat 34 slides in the top surface of the support platform 10, thereby realizing the adjustment capability of the elastic support leg 30. At the same time, it can limit the elastic support leg 30, preventing the elastic support leg 30 from tilting or detaching relative to the T-slot, and improving the stability of the elastic support leg 30 on the support platform 10. Regardless of the implementation method, it is sufficient that the elastic support leg 30 is arranged around the vacuum suction cup 20, so that it can provide multi-point support for the plate-shaped workpiece together with the vacuum suction cup 20.

[0037] In the above embodiments, the clearance holes 111 are arranged in the same adjustment mounting groove 11, and the multiple clearance grooves are spaced apart along the length direction of the adjustment mounting groove 11. In another embodiment, the multiple clearance holes 111 are arranged in multiple adjustment mounting grooves 11, and can be arranged in rows or columns along a certain direction, or can be arranged in a dot matrix.

[0038] In the above embodiments, the elastic support leg 30 achieves position adjustment relative to the support platform 10 through a sliding connection between the bottom connecting seat 34 and the adjusting mounting groove 11. This allows for a larger range of motion and higher adjustment precision for the elastic support leg 30. In another embodiment, the support platform 10 has a planar structure with multiple connecting holes. The bottom of the connecting seat 34 has a pin, which engages with the connecting holes to position the elastic support leg 30. Therefore, the elastic support leg 30 can achieve position adjustment relative to the support platform 10 through engagement with multiple connecting holes. This adjustment method offers higher stability and prevents changes in relative position due to pressure.

Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the protection scope of this utility model.
