Description

Technical Field

[0001] This application relates to the field of UTG stripe detection technology, and in particular to a vacuum adsorption stripe detection stage. Background Technology

[0002] A vacuum adsorption stripe inspection stage is a device used to inspect surface stripes or defects. It is commonly used in industrial production for precision inspection, especially for materials with high precision requirements such as thin films, optical components, and metal surfaces. Its main feature is that the object to be inspected is fixed on the stage surface by vacuum adsorption, ensuring its stability and preventing movement during the inspection process, thereby improving the accuracy and precision of the inspection. It is commonly used in the processing and manufacturing of ultra-thin glass.

[0003] Existing technologies, such as the utility model patent with publication number CN219455982U, disclose an optical glass stripe detection device. This patent includes a detection platform, an adjustment platform, and a placement stage. A column is provided above the detection platform. An amplification component is fixedly connected to a telescopic component. A detection component is provided above the amplification component and is fixedly connected to the output end of an electro-hydraulic component. A sliding component is fixedly connected to the side of the electro-hydraulic component away from the detection component. The sliding component is slidably connected to the inside of a sliding groove. The adjustment platform is located above the detection platform, and the placement stage is located above the adjustment platform. Ultimately, this device expands the detection range while facilitating detection. Finally, the angle can be adjusted to observe and detect the stripes of optical glass from different angles, reducing detection errors.

[0004] In the processing and manufacturing of ultra-thin glass, it was found that the existing UTG stripe detection stage lacks an angle scale, and the angle between the light source and the ultra-thin glass cannot be determined, which makes it easy to produce errors in UTG stripe observation. At the same time, the glass of the stripe detection stage is mostly installed by a slot, which requires multiple people to cooperate to install it properly. This not only makes the UTG sample easy to break, but also causes time and labor problems. Utility Model Content

[0005] One of the technical problems that this application aims to solve is that the existing UTG stripe detection stage lacks an angle scale, and the angle between the light source and the ultra-thin glass cannot be determined, which makes it easy to produce errors in UTG stripe observation. At the same time, the glass of the stripe detection stage is mostly installed by a slot, which requires multiple people to cooperate to install it properly. This not only makes the UTG sample easy to break, but also results in the disadvantages of being time-consuming and laborious.

[0006] To address the aforementioned technical problems, this application provides a vacuum adsorption stripe detection stage, comprising:

[0007] The control panel has a rotating shaft rotatably connected to its upper surface.

[0008] The slide rail has its lower surface fixedly connected to the upper surface of the rotating shaft.

[0009] Support frames are installed at both ends of the inner wall of the slide rail;

[0010] A vacuum suction cup is mounted on the surface of the support frame and is fixedly connected to the surface of the support frame.

[0011] A vacuum pump is installed on one side of the operating table and is fixedly connected to the side wall surface of the operating table.

[0012] The controller has one side surface fixedly connected to the side wall surface of the operating table, and the controller is electrically connected to the vacuum pump.

[0013] The foot switch module is located on the lower surface of the control panel and is electrically connected to the controller.

[0015] The adjustment mechanism is located at one end of the support frame and the slide rail that are close to each other; and

[0016] The positioning mechanism is located on the arc surface at one end of the rotating shaft;

[0017] The adjusting mechanism includes a slider, the upper surface of which is fixedly connected to the lower surface of the support frame. The slider is slidably connected to the inner wall of the slide rail. Sliding holes are provided on both sides of the slide rail. Sliding rods are fixedly connected to both sides of the slider. The arc surface of the sliding rod is slidably connected to the inner wall of the sliding hole. The positioning mechanism includes a connecting plate, one end of which is fixedly connected to the arc surface of the rotating shaft. A pressing shaft is threaded through one end of the connecting plate. A pressing block is fixedly connected to the bottom end of the pressing shaft.

[0018] In some embodiments, the adjustment mechanism further includes a support rod, the bottom end of which is fixedly connected to one side of the upper surface of the slider. An adjustment frame is slidably connected to the arc surface of the support rod. A spring is fitted onto the arc surface of the support rod, and both ends of the spring are fixedly connected to the support rod and the adjustment frame, respectively. A movable plate is fixedly connected to both ends of the adjustment frame. The movable plate has a vertical cross-section, and its surface slides through the arc surface of the slider. A positioning block is fixedly connected to the lower surface of the movable plate, and several locking blocks are fixedly connected to the lower surface of the positioning block. Racks are fixedly connected to both sides of the slide rail.

[0019] In some embodiments, the cross-section of the locking block is conical, and a friction pad is fixedly connected to the surface of the locking block, with the surface of the friction pad engaging with the tooth surface of the rack.

[0020] In some embodiments, a pull plate is fixedly connected to one side surface of the adjustment frame, and grooves are provided on both sides of the pull plate.

This ensures the alignment accuracy between the UTG sample and the optical detection system, reducing detection errors. Simultaneously, the tilt angle of the UTG can be adjusted by the rotating shaft, and combined with the angle scale, it supports optical interference stripe detection at multiple incident angles, adapting to the optimization needs of different light sources. The mechanical structure of the slide rail translation and the rotating shaft linkage can work with the optical system to complete full-coverage scanning of the curved or tilted surface of the UTG, suitable for detecting the bending area of ​​folding screen glass. The operator controls the vacuum pump strength by stepping on the pedal, such as light stepping for low suction pre-fixation and heavy stepping for high suction locking, freeing up hands and improving efficiency, while avoiding UTG overpressure damage due to misoperation. The controller integrates vacuum pump pressure, foot switch signal and motion control commands to achieve adaptive adjustment of adsorption strength and detection process.

[0053] Simultaneously, a nano-oleophobic coating (contact angle > 110°) is applied to prevent oil stains from reducing the sealing performance.

[0054] The specific setup and function of the adjustment mechanism 4 and the positioning mechanism 5 will be explained in detail below.

[0055] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting mechanism 4 includes a slider 401, which can slide and limit the position of the support frame 9. The upper surface of the slider 401 is fixedly connected to the lower surface of the support frame 9, and the slider 401 is slidably connected to the inner wall of the slide rail 10. The slider 401 can slide with the slide rail 10. Sliding holes 402 are provided on both sides of the slide rail 10. Sliding rods 407 are fixedly connected to both ends of the slider 401. The sliding rods 407 and the sliding holes 402 can move quickly and prevent the slider 401 from shifting. The position is offset, and the arc surface of the slide rod 407 is slidably connected to the inner wall of the slide hole 402. The adjustment mechanism 4 also includes a support rod 403, which can raise and lower the position of the adjustment frame 405. The bottom end of the support rod 403 is fixedly connected to one side of the upper surface of the slider 401. The arc surface of the support rod 403 is slidably connected to the adjustment frame 405. A spring 404 is sleeved on the arc surface of the support rod 403. The compressive force generated by the spring 404 can compress and fix the position of the adjustment frame 405. The two ends of the spring 404 are respectively connected to the support rod 403 and the adjustment frame 405. The frame 405 is fixedly connected, and both ends of the adjusting frame 405 are fixedly connected to movable plates 408. The movable plates 408 can drive the adjustment of the position of the positioning block 409, facilitating the separation of the positioning block 409 and the locking block 411 from the rack 410. The cross-section of the movable plate 408 is vertical, and the surface of the movable plate 408 slides through the arc surface of the slide rod 407. The lower surface of the movable plate 408 is fixedly connected to the positioning block 409, and the lower surface of the positioning block 409 is fixedly connected to several locking blocks 411. The locking blocks 411 can effectively and conveniently engage with the rack 410. The toothed surfaces are engaged and limited. Both sides of the slide rail 10 are fixedly connected to racks 410. The cross-section of the locking block 411 is conical. The surface of the locking block 411 is fixedly connected to a friction pad 412. The friction pad 412 can increase friction and facilitate better fixation of the entire rotating shaft 2. The surface of the friction pad 412 engages with the toothed surfaces of the rack 410. One side of the adjusting frame 405 is fixedly connected to a pull plate 406. The pull plate 406 can easily stretch and move the position of the adjusting frame 405. Grooves are provided on both sides of the pull plate 406.

[0056] Reference Figure 4As shown in this embodiment: the positioning mechanism 5 includes a connecting plate 51, which can provide support and limit the installation. One end of the connecting plate 51 is fixedly connected to the arc surface of the rotating shaft 2. A pressing shaft 52 is threaded through one end of the connecting plate 51, which can move and press the pressing block 55. The pressing block 55 is fixedly connected to the bottom end of the pressing shaft 52. The positioning mechanism 5 also includes a guide rail 53, which can slide and guide the pulley 54 to reduce friction. One side of the guide rail 53 is fixedly connected to the bottom arc surface of the rotating shaft 2. The lower surface of 51 is rotatably connected to a pulley 54. The arc surface of the pulley 54 is slidably connected to the inner wall of the guide rail 53. The lower surface of the extrusion block 55 is fixedly connected to an extrusion pad 57. The extrusion limit between the extrusion pad 57 and the anti-slip pad 56 can increase friction and facilitate better fixation of the rotating shaft. The surface of the operating table 1 is fixedly connected to an anti-slip pad 56 at the position corresponding to the connecting plate 51. The surface of the extrusion pad 57 abuts against the surface of the anti-slip pad 56. The vacuum suction cup 8 is a high-elasticity polyurethane suction cup. The surface of the vacuum suction cup 8 is provided with micron-level pits and coated with a nano oleophobic coating.

[0057] Working principle: During the operation of the UTG stripe inspection station, the spacing of the support frames 9 at both ends of the slide rail 10 needs to be adjusted according to the size of the ultra-thin glass, so that the ultra-thin glass is placed on the support frame 9. At the same time, the ultra-thin glass is adsorbed and fixed by the vacuum suction cup 8. Then, pull the pull plate 406 on the upper surface of the slider 401, so that the pull plate 406 drives the adjustment frame 405 to slide and rise along the arc surface of the support rod 403 fixed on the surface of the slider 401. At this time, the moving plates 408 at both ends of the adjustment frame 405 will cause the locking block 411 on the lower surface of the positioning block 409 to separate from the tooth surface of the rack 410. Then, pull the support frame 9. The slider 401 slides along the inner wall of the slide rail 10, allowing for rapid adjustment of the distance between the two support frames 9. Once the designated position is reached, the pull plate 406 is released, causing the adjustment frame 405 to be compressed by the extrusion force generated by the arc-shaped spring 404 of the support rod 403. At this point, the locking block 411 fixed on the lower surface of the positioning block 409 re-engages with the tooth surface of the rack 410, thus fixing the position of the support frame 9 relatively. During this process, both the slide rail 10 and the support frame 9 are made of electrochemically blackened stainless steel to prevent the influence of light refraction and scattering on the experimental results. Then, the ultrathin glass is placed on the two supports... The support frame 9 is secured with a snap-fit ​​mechanism. Simultaneously, the operator utilizes the combination of the foot switch module 3, controller 7, and vacuum pump 6. Through the mechanical triggering method of the foot switch module 3, the foot signal and the linkage logic of the vacuum pump 6 switch the operating mode by pressing down. The foot pedal force is controlled in increments; light or heavy pressing corresponds to different vacuum intensities. This allows the vacuum suction cup 8 to effectively adsorb, fix, and limit the ultra-thin glass. After fixing the ultra-thin glass, the entire slide rail 10 and the ultra-thin glass within the support frame 9 are rotated via the rotating shaft 2. Precise deflection detection is performed using the angle gauge 11 on the surface of the operating table 1. When the rotating shaft 2 is rotated and adjusted, it can be positioned by means of a fixing mechanism set on one side of the rotating shaft 2. When the rotating shaft 2 is deflected, the connecting plate 51 on one side of the rotating shaft 2 slides along the guide rail 53 fixed at the bottom of the rotating shaft 2 via the pulley 54. After reaching the designated position, the pressing shaft 52 on one end surface of the rotating connecting plate 51 causes the pressing block 55 fixed at the bottom of the pressing shaft 52 to press against the anti-slip pad 56 fixed on the surface of the operating table 1 with the pressing pad 57, thereby increasing friction and quickly fixing the position of the rotating shaft 2. At the same time, it increases the stability of the entire movement of the rotating shaft 2. Then, the UTG stripe detection operation is performed.
