Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal glass suspension conveying, specifically a liquid crystal glass suspension conveying device. Background Technology
[0002] The liquid crystal glass substrate is the core material that makes up the liquid crystal display panel. It is an ultra-thin glass sheet with an extremely flat surface. It is mainly used to support liquid crystal molecules and driving circuits, and directly affects the key performance indicators of the display such as resolution and light transmittance. The liquid crystal glass substrate needs to be transported during processing.
[0003] In the prior art, such as in patent announcement number CN214269343U, a suspended liquid crystal glass conveying and guiding device is disclosed. It includes a frame and a drive mechanism, a mounting base, and guiding components mounted on the frame. The drive mechanism is mounted in the middle of the frame, and the two sides of the drive mechanism are respectively connected to the mounting bases on both sides. A plurality of guiding components are evenly arranged on the top of the mounting base. The drive mechanism includes a drive box, a rack and pinion, and a drive gear. The drive box has a drive chamber inside.
[0004] Although the aforementioned patent converts the friction between the glass and the guide component into rotational friction between the bearing and the fixed shaft to avoid dry friction between the roller and the glass, which would affect the quality of the glass, during the transport process, the large size of the glass substrate and the close spacing between adjacent transport components can lead to collisions and damage. The characteristics of the glass material make it relatively fragile, and its smooth surface can cause scratches and damage during fixing. Therefore, a suspended transport device for liquid crystal glass is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, during the conveying process, due to the large size of the glass substrates and the close proximity of adjacent substrates, they are prone to collisions and damage. The characteristics of glass material make it relatively fragile, and its smooth surface can cause scratches and damage during fixing. This utility model proposes a suspended conveying device for liquid crystal glass.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A suspended conveying device for liquid crystal glass, comprising an I-beam; grooves are formed on both sides of the I-beam, and several pulleys are slidably connected inside the grooves; several fixing holes are equidistantly formed on the bottom surface of the grooves, and springs are installed inside the fixing holes, with limiting beads at the top of the springs; a connecting frame is provided on the side of the pulleys, and a fixing block is fixedly connected to the bottom of the connecting frame; a conical block is fixed to the surface of the fixing block, and side plates are provided on both sides of the surface of the conical block; several through holes are equidistantly formed on the surface of the side plates, and cylinders are installed inside the through holes; an elastic conical suction cup is provided at one end of the cylinder; a solenoid valve is provided on the side of the conical block, and several conduits are provided on the surface of the solenoid valve, with one end of the conduits connected to the cylinder; a control module is provided at the top of the conical block, and the control module is electrically connected to the solenoid valve via wires.
[0007] Preferably, the limiting bead is a hemispherical metal structure with its arc surface protruding from the upper edge of the fixing hole, and its diameter is larger than the distance between the pulley rims.
[0008] Preferably, the axis of the through hole is perpendicular to the plane of the side plate, and the cylinder body is fixed to the inner wall of the through hole by bolts.
[0009] Preferably, the elastic conical suction cup is made of silicone, and its cone apex extends away from the cylinder.
[0010] Preferably, the conduit is a corrugated flexible hose with its two ends respectively connected to the solenoid valve outlet and the cylinder tail end interface.
[0011] Preferably, the fixing block is an I-shaped casting, with a connecting frame and a conical block welded to its upper and lower end faces, respectively.
[0012] The advantages of this utility model are:
[0013] 1. This utility model uses a spring and limiting bead linkage structure designed on the bottom surface of the groove to make the hemispherical limiting bead protrude from the fixing hole under the spring pressure and constrain the movement distance of the pulley, thereby realizing the autonomous separation of the suspension device when sliding on the I-beam, solving the problem of glass substrates colliding and breaking due to excessively close conveying distance, and significantly reducing the product breakage rate.
[0014] 2. This utility model uses a cylinder driven by a through hole in the side plate to drive an elastic conical suction cup. Combining the deformation characteristics of silicone material with the conical apex extension structure design, it forms a progressive contact pressure when adsorbing the glass surface. The negative pressure airflow generated by the solenoid valve connected by the conduit achieves zero-damage adsorption and fixation of the glass, solving the industry pain point of glass scratch damage caused by traditional clamps. The electrical control design with the control module directly connected to the solenoid valve, through the air path connectivity of the corrugated hose conduit, realizes the negative pressure start and stop of each cylinder and the centralized control of the pressure value, solving the problem of uneven local adsorption force causing skewing in large glass. The stability of ultra-large substrate transportation is improved to an industry-leading level. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figures 1-4 As shown, a suspended conveying device for liquid crystal glass includes an I-beam 1; grooves are formed on both sides of the I-beam 1, and several pulleys 2 are slidably connected inside the grooves; several fixing holes are equally spaced on the bottom surface of the grooves, and springs 3 are installed inside the fixing holes; a limiting bead 4 is installed at the top of the springs 3; a connecting frame 5 is provided on the side of the pulleys 2, and a fixing block 6 is fixedly connected to the bottom of the connecting frame 5; a conical block 7 is fixed on the surface of the fixing block 6; side plates 8 are provided on both sides of the surface of the conical block 7; several through holes 9 are equally spaced on the surface of the side plates 8, and a cylinder 10 is installed inside the through holes 9; an elastic conical suction cup 11 is provided at one end of the cylinder 10; a solenoid valve 12 is provided on the side of the conical block 7; several conduits 13 are provided on the surface of the solenoid valve 12, and one end of the conduits 13 is connected to the cylinder 10; a control module 14 is provided on the top of the conical block 7, and the control module 14 is electrically connected to the solenoid valve 12 through a wire.
[0023] During operation, the LCD glass is placed between the two side panels 8. The control module 14 activates the solenoid valve 12, causing the cylinder 10 to push the elastic conical suction cup 11 to contact the glass surface and form a pre-pressure. The solenoid valve 12 draws air through the conduit 13 to generate negative pressure, causing the suction cup 11 to adsorb and fix the glass. During transport, the pulley 2 slides along the groove of the I-beam 1. The spring 3 pushes the limit bead 4 to protrude from the bottom of the groove to separate the distance between adjacent pulleys 2. The spring 3 and the limit bead 4 work together to realize the automatic separation of the pulleys 2, solving the risk of glass collision. The negative pressure adsorption of the air path avoids physical scratches.
[0024] Furthermore, the limiting bead 4 is a hemispherical metal structure with its arc surface protruding from the upper edge of the fixing hole, and its diameter is larger than the distance between the rims of the pulley 2;
[0025] During operation, the hemispherical limiting bead 4 is pushed by the spring 3 so that its arc surface protrudes from the fixing hole. When the pulley 2 slides, the wheel rim is forcibly separated to a constant displacement by the arc surface of the limiting bead 4. The diameter of the hemispherical limiting bead 4 is larger than the wheel rim spacing to ensure the minimum safe distance.
[0026] Furthermore, the axis of the through hole 9 is perpendicular to the plane of the side plate 8, and the cylinder body of the cylinder 10 is fixed to the inner wall of the through hole 9 by bolts;
[0027] During operation, the cylinder body of cylinder 10 is vertically fixed to the inner wall of through hole 9 by bolts, and the piston rod extends and retracts along the axis of through hole 9 to drive the elastic conical suction cup 11 to vertically press the glass.
[0028] Furthermore, the elastic conical suction cup 11 is made of silicone, and its cone tip extends away from the cylinder 10.
[0029] During operation, the elastic conical suction cup 11 made of silicone material deforms at the top of the cone and wraps around the edge of the glass when pushed by the cylinder 10. After negative pressure adsorption, the silicone elasticity recovers to form a sealed cavity.
[0030] Furthermore, the conduit 13 is a corrugated hose structure, with its two ends respectively connected to the air outlet of the solenoid valve 12 and the tail end interface of the cylinder 10.
[0031] During operation, the two ends of the corrugated hose conduit 13 are connected to the air outlet of the solenoid valve 12 and the tail end of the cylinder 10. When the cylinder 10 extends or retracts, the hose deformation compensates for the pipeline displacement.
[0032] Furthermore, the fixing block 6 is an I-shaped casting, with the connecting frame 5 and the conical block 7 welded to the upper and lower end faces respectively;
[0033] During operation, the connecting frame 5 is welded to the upper end of the I-shaped fixing block 6 and the conical block 7 is welded to the lower end, so that the vibration load is transmitted and dispersed through the rigid transmission of the I-shaped cross section.
[0034] Working principle: The device starts the solenoid valve 12 through the control module 14 to draw air into the cylinder 10 through the conduit 13 to generate negative pressure, which drives the elastic conical suction cup 11 to adsorb and fix the liquid crystal glass between the two side plates 8. At the same time, when the pulley 2 slides in the groove of the I-beam 1, the spring 3 pushes the limit bead 4 to protrude out of the bottom surface of the groove to forcibly separate the distance between adjacent pulleys 2, so as to achieve dual protection of zero collision and non-destructive clamping of the glass during the conveying process.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
