Abstract
Description
Technical Field
[0001] The invention relates to the technical field of substrate loading, in particular to a loading rack for processing liquid crystal substrates. Background Art
[0002] The loading rack for liquid crystal substrate processing is mainly used in the front-end process to support and position the liquid crystal substrate. The loading rack supports convenient loading and unloading operations through a loading machine, an unloading machine or manual methods, thereby improving the automation and efficiency of the production line.
[0003] However, there are still some problems with the existing loading racks for processing liquid crystal substrates:
[0004] First, the slide groove design of the existing loading rack for liquid crystal substrate processing is originally intended to ensure stable transmission and precise positioning of the substrate. However, with the frequent loading and unloading of substrates, although the internal space of the loading rack is ample, it cannot escape the erosion of continuous pressure and wear, causing the slide groove structure to gradually deform. This deformation directly destroys the precise alignment between the slide grooves, and the spacing is inconsistent, which seriously affects the positioning accuracy of the subsequent placement of the substrate. At the same time, as time goes by, the wear degree of the slide groove varies, which aggravates the problem of inconsistent spacing and increases the difficulty of positioning.
[0005] As a precision component, the surface flatness, edge sharpness and internal structural integrity of the liquid crystal substrate are extremely important. When the degree of wear between the slide grooves is different, the slide grooves are very likely to cause improper extrusion, scratches or collisions on the substrate, which can easily cause surface scratches, edge damage and even damage to the internal structure, thereby reducing the yield rate, increasing costs, and adversely affecting subsequent processing such as coating and cleaning.
[0006] Secondly, in the process of manually adjusting the distance between the slide slots, the operator needs to open and close the buckles at the four corners of the movable plate one by one. When the buckles are unlocked, elastic force and mechanical impact will be generated instantly. For those substrates that have been tightly fitted in the slide slots, these elastic force and mechanical impact will directly cause scratches on their surfaces, damage to their edges or damage to their internal structures. Since the thickness of the liquid crystal substrate is very small, its ability to withstand external forces is extremely limited. Therefore, any tiny external force can easily damage the surface quality of the liquid crystal substrate;
[0007] Secondly, since the degree of wear of each chute varies, this difference is further magnified during the manual adjustment process. The chute with less wear can still maintain a certain gap and provide a certain buffer space for the substrate, while the chute with severe wear causes the substrate to fit closely with it or even squeeze it. In addition, since the four buckles need to be opened manually in sequence, this asynchronous operation method often causes uneven force on the movable plate during movement. The vibration force generated each time the buckle is opened will be concentrated on one corner of the movable plate, causing the movable plate to shake or deviate slightly. This unstable movement state not only increases the risk of damage to the substrate, but also causes additional wear and damage to the chute itself.
[0008] To this end, the present invention provides a loading rack for processing liquid crystal substrates. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. By placing the substrate in the middle of the second rotating shaft, the nested fixing assembly improves the stability of substrate transmission and the accuracy of positioning. First, when the substrate is placed, the second rotating shaft will rotate based on friction, and the second rotating shaft will convert sliding friction into rolling friction, which greatly reduces the friction between the substrate and the upper plate rack. This not only reduces the wear of the substrate during transmission, but also avoids potential thermal damage to the substrate caused by the heat generated by friction. Secondly, the rolling mechanism enables the substrate to maintain a more stable motion state during transmission, reducing the position deviation of the substrate caused by vibration or impact, thereby improving the positioning accuracy. In addition, the rolling mechanism can effectively disperse the pressure of the substrate on the second rotating shaft, reducing the risk of deformation of the second rotating shaft due to long-term pressure, and further ensuring the precise alignment and spacing consistency between the second rotating shafts;
[0022] Compared with the traditional loading rack for processing liquid crystal substrates, firstly, in terms of friction control, the traditional loading rack relies on sliding friction to transfer the substrate, which not only increases the wear between the substrate and the slide groove, but also limits the transmission speed and efficiency. The nested fixed component effectively reduces the friction force by introducing the rolling mechanism of the second shaft, thereby improving the transmission efficiency and the service life of the substrate. Secondly, in terms of positioning accuracy, the spacing inconsistency problem caused by the wear of the slide groove of the traditional loading rack seriously affects the positioning accuracy of the substrate, while the second shaft significantly improves the positioning accuracy and processing quality of the substrate by reducing wear and maintaining the consistency of spacing. Finally, in terms of cost control, the traditional loading rack increases the production cost due to the high damage rate of the substrate and the low yield rate, while the nested fixed component helps to reduce the production cost and improve the overall production efficiency by reducing the damage of the substrate and improving the yield rate.
[0023] Among them: the nested structure composed of the first rotating shaft, the second rotating shaft and the third rotating shaft plays a key role in the substrate transmission. The nested design not only enhances the stability and durability of the system, but also optimizes the performance of the rolling mechanism. Specifically, the first rotating shaft, as the inner shaft, rotates inside the sliding frame, and realizes the conversion of rolling friction through the sliding connection with the limit groove, which effectively reduces the friction during the substrate transmission. The second rotating shaft, as the outer shaft, is concentrically arranged with the first rotating shaft, and the sliding groove on its surface is embedded with a number of third rotating shafts. These third rotating shafts, as the central shaft, play a role in dispersing pressure and maintaining balance during the rolling process. Therefore, the nested design makes the rolling mechanism of the entire second rotating shaft more stable when bearing the weight of the substrate and transmitting power.
[0024] Among them: the protective cover, as a component that directly contacts the substrate, can provide a buffering effect when the substrate is placed, reduce the impact and friction between the substrate and the upper plate rack, and protect the surface of the substrate from damage. Secondly, the protective cover also has a certain shock absorption ability, which can absorb the vibration generated during the transmission process. In addition, the deformation holes opened on the surface of the protective cover further enhance its elastic performance, so that the protective cover can undergo a slight deformation when subjected to pressure, thereby better adapting to the shape and size changes of the substrate;
[0025] Wherein: the buffer spring is combined with the fixed connection with the sliding frame and the limiting effect of the limit groove, so that the buffer spring can not only provide the necessary supporting force when the substrate is placed, but also absorb and disperse the impact and vibration from the substrate during the transmission process, so that the combination of rigidity and elastic mechanism improves the stability of substrate transmission and avoids the wear or deformation of the slide groove caused by direct impact;
[0026] Among them: Because the shafts are nested, when a shaft fails or needs to be replaced, the operator can disassemble and replace it separately without large-scale disassembly of the entire structure. This modular nested design not only shortens maintenance time, but also reduces downtime losses;
[0027] Among them: Since the second rotating shaft adopts an I-shaped design, the cross-sectional area in the horizontal direction is increased, which greatly enhances its ability to bear the weight of the substrate. At the same time, the nested design adopted between the rotating shafts ensures a high rotation rate, so that the second rotating shaft can form a wide and uniform pressure distribution with the substrate through a multi-point contact mechanism during its own rotation. The multi-point contact mechanism not only optimizes mechanical transmission, but also effectively disperses the pressure on the substrate, thereby reducing the risk of local wear of the substrate, thereby minimizing the wear between the substrate and the second rotating shaft;
[0028] Wherein: each third rotating shaft is slidably connected with the motion grooves on the first rotating shaft and the second rotating shaft through a round protrusion. This structure enables the third rotating shaft to serve as an additional support point, dispersing the pressure originally concentrated on the second rotating shaft to multiple points, thereby improving the vertical bearing capacity of the second rotating shaft, and then indirectly improving the vertical bearing capacity of the movable plate as a whole, and preventing it from being deformed or twisted due to long-term placement of the base plate;
[0029] Among them: when the substrate enters the middle of the second rotating shaft in an inclined state, the buffer spring can absorb the tilting torque of the substrate through its own elastic deformation. At the same time, under the action of the limiting groove, this elastic effect will not be too large, but will gradually act on the substrate through each buffer spring during the continuous entry of the substrate, and gradually guide the substrate to move to the correct position.
[0030] 2. The operator only needs to turn the rotating wheel to drive the clamping block to clamp or loosen the limit strip through the movement of the motion rod and the second inclined block, so as to adjust the movable plate. The synchronous limit assembly improves the convenience and efficiency of operation, because the operator no longer needs to open and close the buckles at the four corners of the movable plate one by one, avoiding cumbersome operation steps and possible human errors. At the same time, since the clamping block moves synchronously, the synchronously moving clamping block ensures that the movable plate is evenly stressed during the movement, avoiding small shaking or offset caused by asynchronous operation, thereby greatly reducing the risk of damage to the substrate. In addition, the synchronous movement also reduces the friction and wear between the movable plate and the substrate, thereby extending the service life of the upper plate rack;
[0031] Compared with the existing technology of manually opening and closing the buckles one by one to adjust the distance between the slide grooves, the synchronous limit assembly eliminates the influence of the elastic force and mechanical impact generated when the buckles are unlocked on the surface quality of the substrate, because the operator no longer needs to directly operate the buckles, thereby avoiding these potential damage factors. Secondly, the difference in the degree of wear of each slide groove in the existing technology is magnified during the manual adjustment process, while the synchronous limit assembly realizes the adjustment by synchronously moving the clamping block, reducing the risk of damage to the substrate and additional wear of the slide groove caused by uneven wear of the slide groove. In addition, the synchronous movement also ensures the stability of the movable plate during the movement process, further improving the processing accuracy and the accuracy of substrate positioning;
[0032] When the operator rotates the rotating wheel, the two moving rods inside the elliptical groove will move relative to each other. This movement converts the linear motion into synchronous lateral motion through the oblique block resistance between the second oblique block and the first oblique block. The synchronous lateral motion not only ensures that the clamping block can move smoothly and synchronously to clamp or release the limit strip, but also improves the efficiency and stability of the entire adjustment process. In addition, since the clamping block moves synchronously, while significantly shortening the clamping and releasing, the mechanical impact on the limit strip is effectively reduced by tightly clamping, further protecting the substrate inside the loading rack.
[0033] Among them: when the clamping block clamps the limit strip, the convex particles can better fit the surface of the limit strip, effectively preventing the substrate from sliding or deflecting during the transmission process. This increased friction not only improves the accuracy of substrate positioning, but also reduces the processing error caused by substrate shaking or deflection, thereby improving the overall processing accuracy and product quality;
[0034] Among them: the design of the rotating wheel and the elliptical groove applies the unlocking and locking force mainly in the radial direction, thereby effectively avoiding the lateral elastic force and mechanical stress generated when unlocking the buckle in the prior art. When the operator turns the rotating wheel, a radial rotational force is generated. This force is converted into a linear movement of the moving rod through the mechanical structure inside the synchronous limit assembly, thereby realizing the synchronous movement and clamping or loosening action of the clamping block. In this process, all mechanical effects are controlled within the radial dimension, thereby ensuring that the substrate is protected from any lateral elastic force or impact force, thereby reducing the risk of damage to the substrate. The further synchronous limit assembly strengthens the basic function of the loading rack as a substrate carrying platform, and also highlights the ability to protect the safety of the substrate.

The upper and lower sides of the upper plate frame 11 are recessed inward to form a recessed surface, and the recessed surface is provided with rectangular and equidistantly arranged card slots running through it.
[0060] The upper plate frame 11 can be used in conjunction with an external upper plate machine and an external lower plate machine.
[0061] The working principle of the present invention in combination with the above is as follows:
[0062] The following is the initial state: the buffer spring 23 is not compressed, the first rotating shaft 25 is located on the side of the limiting groove 22 away from the inner wall of the fixed frame 21, the two clamping curved rods 33 are both in contact with the rotating wheel 31, the reset spring 34 is not compressed, the moving rods 36 are both located on the side with the depression in the elliptical groove 32, the clamping block 39 does not interfere with the limiting strip 12, the second inclined block 310 is located in the middle of the first inclined block 38, the protective cover 28 is not compressed, the movable plate 13 is located on the side of the limiting strip 12 away from the inner wall of the upper plate frame 11, and the clamping block 39 has clamped the limiting strip 12.
[0063] The following are the specific steps of the work:
[0064] Wherein, the spacing of the movable plate 13 is adjusted:
[0065] like Figures 6 to 10 As shown, after the production of the liquid crystal substrate is completed, first, the operator adjusts the distance between the movable plate 13 and the upper plate frame 11 according to the size of the liquid crystal substrate.
[0066] The operator needs to press the two clamping bent rods 33, and this action is amplified by the lever principle. The middle part of the clamping bent rod 33 is hinged to the outer surface of the movable plate 13, so that an effective lever arm is formed between the pressing point and the hinge point. As the return spring 34 is compressed, its end away from the pressing point will correspondingly rotate in the direction away from the rotating wheel 31, thereby releasing the restriction of the clamping bent rod 33 on the rotating wheel 31.
[0067] At this time, the operator can rotate the rotating wheel 31 through the handle. As the rotating wheel 31 rotates, the elliptical groove 32 on its outer surface rotates synchronously, thereby causing the relative position between the two elliptical blocks inside the elliptical groove 32 to change, that is, the two elliptical blocks push the moving rod 36 to slide along its long axis direction.
[0068] Since the moving rod 36 is restricted by the hollow block 35 and can only slide in a straight line along the internal track of the hollow block 35, as the moving rod 36 slides in the direction away from the rotating wheel 31, the second inclined block 310 thereon interacts with the first inclined blocks 38 on both sides. Since the inclined edges are parallel and tightly fitted, this sliding not only transmits force, but also generates a component force that causes the first inclined blocks 38 to expand outward. This component force prompts the two first inclined blocks 38 to slide to both sides along the inner wall track of the sliding frame 37, thereby driving the clamping block 39 to gradually loosen the clamping of the limit strip 12.
[0069] After the clamping block 39 is released, the operator can push the hollow block 35 to make the movable plate 13 and the limit bar 12 slide relative to each other. When it is observed that the distance between the movable plate 13 and the inner wall of the upper plate frame 11 is appropriate, the operator releases the clamping bent rod 33, and the reset spring 34 will stretch and re-limit the rotation of the rotating wheel 31.
[0070] Among them, the placement of the liquid crystal substrate:
[0071] like Figures 2 to 5 As shown, when the operator adjusts the distance between the movable plate 13 and the inner wall of the upper plate frame 11 according to actual needs and observes that the edge of the liquid crystal substrate can fit the protective cover 28, the operator gently places a liquid crystal substrate between a row of second rotating shafts 26. The I-shaped cross-section design of the second rotating shafts 26 not only enhances the structural strength, but also provides good rotation flexibility and stability. As the substrate gradually goes deeper, its edge first contacts the protective cover 28. The softness and high elasticity of the protective cover 28 itself enable the protective cover 28 to quickly respond to the contact of the substrate and undergo a small deformation. This deformation not only reduces the impact force on the substrate, but also creates a slight sense of wrapping, effectively preventing scratches or wear caused by direct contact.
[0072] At the same time, based on the friction force, the entry of the substrate promotes the rotation of the second shaft 26. As the second shaft 26 rotates, the third shaft 27 slides relatively inside the second shaft 26 and the first shaft 25. This nested design not only enhances the overall stability of the structure, but also makes the rotation process smoother and more controllable. Most importantly, the rotation of the second shaft 26 converts the sliding friction generated by the insertion of the substrate in the prior art into rolling friction, thereby reducing unnecessary friction generated when the substrate enters the upper plate frame 11, thereby preventing the substrate from being excessively worn.
[0073] Then, the operator places the remaining liquid crystal substrates between the remaining second rotating shafts 26 in sequence according to the above steps.
[0074] In addition, in addition to the above method, the operator can also put the upper plate rack 11 with adjusted spacing into the lower plate machine, and place the substrate in the upper plate rack 11 through the lower plate machine.
[0075] Among them, the loading of the substrate:
[0076] After the liquid crystal substrate is placed in the upper frame 11 , the operator can pick it up through the card slot on the top of the upper frame 11 and send the upper frame 11 to the next process for processing.
[0077] During the movement of the operator, the upper plate frame 11 will inevitably be shaken or vibrated. At this time, the buffer spring 23 will absorb the external vibration and shaking. At the same time, the buffer spring 23 provides elastic support for the liquid crystal substrate, and the first rotating shaft 25 located inside the limiting groove 22 and the sliding frame 24 provide rigid support for the liquid crystal substrate. The dual mechanism is combined with each other, which can not only effectively prevent the liquid crystal substrate from being worn by external force during the transmission process, but also when the operator does not place the liquid crystal substrate parallel to the middle of the second rotating shaft 26, the buffer spring 23 can also provide it with necessary correction capabilities.
[0078] When the operator holds the upper plate rack 11 to the next process location, the operator can choose to load the substrates in the upper plate rack 11 one by one, or use a loading machine to load the liquid crystal substrates.
[0079] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0080] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
