Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of substrate feeding, in particular to a feeding rack for liquid crystal substrate processing. BACKGROUND
[0002] The feeding rack for liquid crystal substrate processing is mainly used in the front-end process to support and position the liquid crystal substrate, and the feeding rack support is convenient for feeding and discharging through the upper plate machine, lower plate machine or manual operation, thereby improving the automation and efficiency of the production line.
[0003] However, the existing feeding rack for liquid crystal substrate processing still has some problems:
[0004] Firstly, the existing feeding rack for liquid crystal substrate processing is designed to ensure stable transmission and accurate positioning of the substrate. However, with frequent loading and unloading of the substrate, the internal space of the feeding rack is sufficient, but it is difficult to escape the continuous pressure and erosion, resulting in gradual deformation of the chute structure. This deformation directly destroys the precise alignment between the chutes, and the spacing is not uniform, which seriously affects the positioning accuracy of the subsequent placement of the substrate. At the same time, as time goes by, the degree of wear of the chutes is different, 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 crucial. When the degree of wear between the chutes is not uniform, the chutes are prone to cause improper extrusion, scratching or impact on the substrate, which can easily cause surface scratches, edge damage and internal structural damage, thereby reducing the yield, increasing the cost, and adversely affecting subsequent processing such as coating and cleaning.
[0006] Secondly, during the manual adjustment of the spacing between the chutes, the operator needs to open and close the four corner buckles of the movable plate one by one. When the buckle is unlocked, an instantaneous elastic force and mechanical impact will be generated. For those substrates that are tightly fitted in the chutes, these elastic force and mechanical impact will directly cause surface scratches, edge damage or internal structural damage. Since the thickness of the liquid crystal substrate is very small, its ability to withstand external force is extremely limited, so any small external force can easily damage the surface quality of the liquid crystal substrate.
[0007] Secondly, due to the difference in the degree of wear of each chute, the difference is further amplified in the manual adjustment process. The less worn chute can still maintain a certain gap to provide a certain buffer space for the substrate, while the severely worn chute causes the substrate to be tightly attached to it, and even extrusion. In addition, due to the need to open four buckles one by one, this asynchronous operation mode often causes uneven stress on the moving plate during movement. The vibration force generated each time the buckle is opened will be concentrated on one corner of the moving plate, causing the moving plate to shake or shift slightly. This unstable motion state not only increases the risk of damage to the substrate, but also causes additional wear and damage to the chute itself.
[0008] Therefore, the application provides a loading rack for liquid crystal substrate processing. SUMMARY

[0020] Compared with the prior art, the present application has the following advantages:
[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, it will rotate the second rotating shaft based on friction, and the second rotating shaft will convert sliding friction into rolling friction, greatly reducing the friction between the substrate and the upper plate frame. This not only reduces the wear of the substrate during transmission, but also avoids potential thermal damage to the substrate caused by friction. Second, the rolling mechanism allows 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, further ensuring the precise alignment and consistent spacing of the second rotating shafts.
[0022] Compared with the traditional liquid crystal substrate processing feeding rack, first in the friction control aspect, the traditional feeding rack relies on sliding friction to transmit the substrate, which not only increases the wear between the substrate and the sliding groove, but also limits the transmission speed and efficiency. The nested fixing assembly effectively reduces the friction by introducing the rolling mechanism of the second rotating shaft, improves the transmission efficiency and the service life of the substrate. Second, in terms of positioning accuracy, the inconsistent spacing problem caused by the wear of the traditional feeding rack seriously affects the positioning accuracy of the substrate. The second rotating shaft significantly improves the positioning accuracy and processing quality of the substrate by reducing wear and maintaining consistent spacing. Finally, in terms of cost control, the traditional feeding rack increases production costs due to high substrate damage rate and low yield. The nested fixing assembly reduces substrate damage and improves yield, which helps to reduce production costs and improve overall production efficiency.
[0023] The nested structure formed by 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 limiting groove, effectively reducing the friction during substrate transmission. The second rotating shaft, as the outer shaft, is concentrically arranged with the first rotating shaft, and the sliding groove on the surface of the second rotating shaft is embedded with several third rotating shafts. These third rotating shafts, as the middle shafts, play a role in dispersing pressure and maintaining balance during the rolling process. The nested design makes the rolling mechanism of the entire second rotating shaft more stable when bearing the weight of the substrate and the transmission power.
[0024] The protective sleeve, as a component directly contacting the substrate, can provide a buffering effect when the substrate is placed, reducing the impact and friction between the substrate and the upper plate frame, and protecting the surface of the substrate from damage. In addition, the protective sleeve also has certain shock absorption capacity, which can absorb the vibration generated during transmission. Furthermore, the deformation holes on the surface of the protective sleeve further enhance its elastic performance, allowing the protective sleeve to deform slightly when subjected to pressure, thereby better adapting to the shape and size changes of the substrate.
[0025] The buffering spring, through the combination of fixed connection with the sliding frame and the limiting effect of the limiting groove, can not only provide necessary support force when the substrate is placed, but also absorb and disperse the impact and vibration from the substrate during transmission. The combination of rigidity and elasticity mechanism improves the stability of substrate transmission and avoids the wear or deformation of the sliding groove caused by direct impact.
[0026] The nested design between each rotating shaft allows the operator to individually disassemble and replace a faulty or damaged rotating shaft without the need for large-scale disassembly of the entire structure. This modular nested design not only shortens the maintenance time, but also reduces downtime losses.
[0027] The second rotating shaft adopts an I-shaped design, which increases the cross-sectional area in the horizontal direction and greatly enhances its ability to bear the weight of the substrate. The nested design between the rotating shafts ensures high rotation rate, allowing the second rotating shaft to form extensive and uniform pressure distribution with the substrate through the multi-point contact mechanism during its own rotation. The multi-point contact mechanism not only optimizes the mechanical transmission, but also effectively disperses the pressure borne by the substrate, thereby reducing the risk of local wear of the substrate and minimizing the wear between the substrate and the second rotating shaft.
[0028] Wherein: each third rotating shaft is connected with the first rotating shaft and the second rotating shaft through the round convex block and the movement groove, which makes the third rotating shaft as an additional support point to disperse the pressure on the second rotating shaft to multiple points, thereby improving the vertical bearing capacity of the second rotating shaft, and indirectly improving the vertical bearing capacity of the movable plate as a whole, and preventing the deformation or distortion of the movable plate due to long-term placement of the substrate;
[0029] Wherein: when the substrate enters the middle of the second rotating shaft in an inclined state, the buffer spring can absorb the inclined torque of the substrate through its elastic deformation, and under the action of the limiting groove, the elastic action will not be too large, but will gradually act on the substrate through each buffer spring in the process of the substrate entering, and gradually guide the substrate to move to the correct position.
[0030] 2. The operator only needs to rotate the rotating wheel, which can drive the clamping block to clamp or release the limiting strip through the movement of the movement rod and the second inclined block, thereby adjusting the movable plate, and the synchronous limiting assembly improves the convenience and efficiency of operation, because the operator does not need to open and close the buckles on the four corners of the movable plate one by one, avoiding tedious operation steps and possible human errors, and because the clamping blocks move synchronously, the synchronous clamping blocks ensure that the movable plate is evenly stressed during movement, avoiding small amplitude shaking or deviation caused by asynchronous operation, thereby greatly reducing the risk of substrate damage, in addition, synchronous movement also reduces the friction and wear between the movable plate and the substrate, thereby prolonging the service life of the plate rack;
[0031] Compared with the existing technology of manually opening and closing the buckles one by one to adjust the distance between the sliding grooves, the synchronous limiting assembly eliminates the influence of the elastic force and mechanical impact generated when the buckle is unlocked on the surface quality of the substrate, because the operator no longer needs to directly operate the buckle, thereby avoiding these potential damage factors, secondly, the difference in wear degree of each sliding groove is amplified during manual adjustment in the existing technology, while the synchronous limiting assembly adjusts by moving the clamping blocks synchronously, reducing the risk of substrate damage and additional wear of the sliding groove caused by uneven wear of the sliding groove, in addition, synchronous movement also ensures the stability of the movable plate during movement, further improving the processing precision and the accuracy of substrate positioning;
[0032] Wherein: when the operator rotates the rotating wheel, the two moving rods inside the elliptical groove will move relative to each other, and this movement will be converted into synchronous lateral movement through the abutment of the second inclined block and the first inclined block, which not only ensures that the clamping block can move smoothly and synchronously to clamp or release the limiting strip, but also improves the efficiency and stability of the entire adjustment process. In addition, since the clamping block moves synchronously, it significantly shortens the clamping and releasing time, effectively reduces the mechanical impact on the limiting strip, and further protects the substrate inside the feeding rack.
[0033] Wherein: when the clamping block clamps the limiting strip, the convex particles can better adhere to the surface of the limiting strip, effectively preventing the substrate from sliding or shifting during transmission. This increased friction not only improves the accuracy of substrate positioning, but also reduces processing errors caused by substrate shaking or shifting, thereby improving overall processing precision and product quality.
[0034] Wherein: the design of the rotating wheel and the elliptical groove mainly applies the unlocking and locking force in the radial direction, effectively avoiding the lateral elastic force and mechanical stress generated when unlocking the buckle in the prior art. When the operator rotates the rotating wheel, a radial rotating force is generated, which is converted into the linear movement of the moving rod through the mechanical structure inside the synchronous limiting assembly, thereby realizing the synchronous movement of the clamping block and the clamping or releasing action. During this process, all mechanical actions are controlled within the radial dimension, ensuring that the substrate is not affected by any lateral elastic force or impact force, thereby reducing the risk of substrate damage. Furthermore, the synchronous limiting assembly enhances the basic function of the feeding rack as a substrate carrying platform, and highlights the protection capability of the substrate safety.

[0056] Each third rotating shaft 27 has a round protrusion fixedly connected to its upper and lower sides. The round protrusions are slidably connected inside the motion groove. The cross-section of the second rotating shaft 26 is set in the shape of an I-beam. The protective sleeve 28 is made of silicone. The outer surface of each protective sleeve 28 has deformation holes symmetrically arranged in a ring at equal intervals.
[0057] The elliptical groove 32 is composed of two intersecting ellipses, and the elliptical groove 32 divides the middle part of the rotating wheel 31 into two tangent elliptical blocks. The side of each clamping rod 33 near the rotating wheel 31 is set as an arc shape, and a silicone sleeve is installed on the side of each clamping rod 33 near the rotating wheel 31. A handle is fixedly connected to the outer surface of the rotating wheel 31.
[0058] Each first inclined block 38 is configured as a trapezoid, with one side of the shorter side of the trapezoid close to the moving rod 36. The second inclined block 310 is also configured as a trapezoid, with the inclined side of the second inclined block 310 parallel to the inclined side of the first inclined block 38. Each first inclined block 38 has an abutting groove on its inclined side, and each second inclined block 310 has an abutting step block fixedly connected to its inclined side. The abutting step blocks are slidably connected inside the abutting groove.
[0059] The movable plates 13 are all convex in shape. Each clamping block 39 has several convex particles fixedly connected in a rectangular equidistant arrangement on the outer surface of the side near the movable plate 13. 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 a rectangular equidistant arrangement of slots.
[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, based on the above implementation, is as follows:
[0062] The following is the initial state: the buffer spring 23 is not compressed, the first rotating shaft 25 is located in the limiting groove 22 on the side away from the inner wall of the fixed frame 21, both clamping cranks 33 are in contact with the rotating wheel 31, the return spring 34 is not compressed, the moving rods 36 are all located in the elliptical groove 32 on the side with the recess, the clamping block 39 is not in contact with the limiting strip 12, the second inclined block 310 is located in the middle of the first inclined block 38, the protective sleeve 28 is not compressed, the movable plate 13 is located on the limiting strip 12 on the side 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 for operation:
[0064] Among them, the spacing of the movable plate 13 is adjusted:
[0065] like Figures 6 to 10 As shown, after the liquid crystal substrate is produced, the operator first 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 presses the two clamping curved rods 33, which is amplified by the principle of leverage, the middle part of the clamping curved rods 33 is hinged to the outer surface of the movable plate 13, so that the pressing point and the hinge point form an effective lever arm, and as the return spring 34 is compressed, the end away from the pressing point will correspondingly rotate away from the rotating wheel 31, thereby releasing the restriction of the clamping curved rods 33 on the rotating wheel 31.
[0067] At this time, the operator can rotate the rotating wheel 31 by the handle, and as the rotating wheel 31 rotates, the elliptical groove 32 on its outer surface rotates synchronously, which causes 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 limited by the hollow block 35 and can only slide linearly along the internal track of the hollow block 35, as the moving rod 36 slides away from the rotating wheel 31, the second inclined block 310 on it interacts with the two first inclined blocks 38, and since the inclined edges are parallel and closely fit, this sliding not only transmits force, but also generates a component force that causes the first inclined blocks 38 to expand outward, which promotes the two first inclined blocks 38 to slide along the internal track of the sliding frame 37 to both sides, thereby gradually loosening the clamping of the clamping blocks 39 on the limiting strip 12.
[0069] After the clamping blocks 39 are loosened, the operator can push the hollow block 35 to make the movable plate 13 slide relative to the limiting strip 12, and when the distance between the movable plate 13 and the inner wall of the upper plate frame 11 is appropriate, the operator releases the clamping curved rods 33, and the return spring 34 will stretch and re-restrict the rotation of the rotating wheel 31.
[0070] Among them, the placement of the liquid crystal substrate is:
[0071] As shown in Figures 2 to 5 When the operator adjusts the distance between the movable plate 13 and the inner wall of the upper plate frame 11 according to the actual needs, and observes that the edge of the liquid crystal substrate can fit the protective sleeve 28, the operator gently places a piece of liquid crystal substrate between a row of second rotating shafts 26, and the second rotating shafts 26 are designed in the shape of an I-beam, which not only enhances the structural strength, but also provides good rotation flexibility and stability, as the substrate gradually penetrates, its edge first contacts the protective sleeve 28, and the softness and high elasticity of the protective sleeve 28 enable the protective sleeve 28 to respond quickly to the contact of the substrate, and deform slightly, which not only reduces the impact force on the substrate, but also produces a slight wrapping feeling, effectively preventing scratches or wear caused by direct contact.
[0072] At the same time, the entering of the substrate pushes the rotation of the second rotating shaft 26, and with the rotation of the second rotating shaft 26, the third rotating shaft 27 slides relatively inside the second rotating shaft 26 and the first rotating shaft 25. This nested design not only enhances the overall stability of the structure, but also makes the rotation process more stable and controllable. Most importantly, the rotation of the second rotating shaft 26 converts the existing technology substrate into sliding friction generated by the entering of the substrate into rolling friction, thereby reducing unnecessary friction generated by the substrate when entering the upper plate frame 11, and preventing the substrate from being excessively worn.
[0073] Then, the operator places the remaining liquid crystal substrates in the remaining second rotating shafts 26 according to the above steps.
[0074] In addition, in addition to the above method, the operator can also place the upper plate frame 11 with adjusted spacing into the lower plate machine, and place the substrate in the upper plate frame 11 through the lower plate machine.
[0075] Among them, the feeding of the substrate:
[0076] After the liquid crystal substrate is placed in the upper plate frame 11, the operator can take it out through the clamping groove on the top of the upper plate frame 11, and send the upper plate 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 which time the buffer spring 23 will absorb the vibration and shaking of the outside world, while the buffer spring 23 provides elastic support for the liquid crystal substrate, and the first rotating shaft 25 and the sliding frame 24 located in the limiting groove 22 provide rigid support for the liquid crystal substrate. Through the combination of the double mechanisms, not only can effectively prevent the liquid crystal substrate from being worn in the transmission process, but also when the operator does not place the liquid crystal substrate parallelly in the middle of the second rotating shaft 26, the buffer spring 23 can also provide the necessary correction ability.
[0078] When the operator holds the upper plate frame 11 to the next process location, the operator can choose to feed the substrates in the upper plate frame 11 one by one, or use the upper plate machine to feed the liquid crystal substrate.
