Description

Technical Field

[0001] This utility model relates to the field of glass substrate technology, and specifically to a spacer fixing mechanism for liquid crystal glass substrates. Background Technology

[0002] In the manufacturing of LCD glass substrates, robots typically place the glass onto an A-frame during loading and unloading. Each glass substrate has a spacer paper on its surface, and the robot uses suction cups to pick up and store the substrates, completing the transfer. Currently, due to production cycle time constraints, the robot speed must be increased. However, the spacer paper on the surface of the LCD glass substrate is prone to detaching during suction cup transfer, leading to production interruptions. This necessitates re-placing the spacer paper on the LCD glass substrate, reducing transport efficiency and increasing the likelihood of dust accumulation on the substrate surface, thus lowering substrate quality and increasing production costs.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a liquid crystal glass substrate spacer fixing mechanism, including: a storage box 1, with limiting plates 4 symmetrically connected to both sides of the upper surface of the storage box 1, and a substrate body 2 movably connected in a storage groove opened on the upper surface of the storage box 1. Spacer body 3 is laid on the upper surface of the storage box 1 and the substrate body 2, and storage cylinders 7 are symmetrically connected to both ends of the storage box 1. A buffer rod 8 is slidably connected to the storage cylinder 7 through a main spring. An adjusting sleeve 9 is screwed to the end of the buffer rod 8 away from the storage cylinder 7, and the adjusting sleeve 9 is movably connected to the lower end of a fixing plate 10. A positioning plate 11 is fixedly connected to the upper end of the fixing plate 10. At the same time, a main screw 14 is movably connected to the end of the positioning plate 11 away from the fixing plate 10 through a bearing. A fastening plate 13 is screwed to the upper end of the main screw 14.

[0018] In this embodiment, the liquid crystal glass substrate body 2 is first placed in the storage slot opened on the surface of the storage box 1, and then the spacer paper body 3 is placed on the surface of the storage box 1 and the substrate body 2. During the placement of the spacer paper, the limiting plate 4 can provide corresponding auxiliary positioning for the spacer paper body 3, and can also reduce the probability of the spacer paper body 3 accidentally falling after placement. Then, the buffer rod 8 that was pulled in advance is released, and the buffer rod 8 returns to its original position under the action of the compressed main spring. Subsequently, the buffer rod 8 can drive the adjusting sleeve 9, the fixing plate 10 and the positioning plate 11 to return to their original positions simultaneously, so that the two sets of positioning plates 11 can clamp the positioning plate simultaneously. The spacer paper body 3 is positioned at both ends to achieve secondary positioning. When the main screw 14 is rotated, the main screw 14 pushes the screwed fastening plate 13 to move down. The fastening plate 13 abuts against both ends of the spacer paper body 3 through the fastening layer provided on the lower surface, thereby completing the fixation of the spacer paper body 3. Thus, during the transmission or storage of the liquid crystal glass substrate, the spacer paper body 3 can always adhere to the surface of the liquid crystal glass substrate body 2, which helps to improve the overall quality of the liquid crystal glass substrate body 2. At the same time, the storage groove 6 and the fitting groove 5 opened on the lower surface of the storage box 1 can facilitate the stacking and storage of the liquid crystal glass substrate as a whole.

[0019] As a preferred embodiment, there are two sets of limiting plates 4. Both sets of limiting plates 4 have an E-shaped structure. The limiting plates 4 are composed of a base plate and a protruding plate. The base plate has a long strip structure, while the cross-section of the protruding plate has a right-angled trapezoidal structure. At the same time, the upper surface of the protruding plate is inclined on the side close to the base plate body 2.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structure of the limiting plate 4 allows the limiting plate 4 to perform preliminary positioning adjustment of the spacer paper body 3 when it is placed on the surface of the storage box 1 and the substrate body 2. It can also effectively prevent the spacer paper body 3 from accidentally falling off the surface of the storage box 1.

[0021] As a preferred embodiment, multiple sets of fitting grooves 5 are opened at equal intervals along the length direction on both sides of the lower surface of the storage box 1. The cross-section of the multiple sets of fitting grooves 5 is a right trapezoidal structure, and the number and position of the fitting grooves 5 correspond one-to-one with the protrusions in the limiting plate 4. At the same time, the two sets of storage grooves 6 opened at both ends of the lower surface of the storage box 1 are rectangular structures.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sizes of the fitting groove 5 and the protrusion in the limiting plate 4 are matched, so that the two sets of storage boxes 1 can be easily stacked together, which facilitates the stacking and storage of the liquid crystal glass substrate body 2, and can also help enhance the stability of the liquid crystal glass substrate body 2 during stacking and storage, and ensure the safety of the liquid crystal glass substrate body 2 during storage.

[0023] As a preferred embodiment, the storage tube 7 has a cylindrical structure, the axial section of the storage tube 7 has a C-shaped structure, and the opening on the end face of the storage tube 7 has a circular structure. The size of the opening on the end face of the storage tube 7 is compatible with that of the buffer rod 8. At the same time, the storage tube 7 is fixedly connected to the groove opened on the end face of the storage box 1.

[0024] In this embodiment, as Figure 3 and Figure 4 The opening at the end face of the storage tube 7 helps to enhance the stability of the relative sliding between the buffer rod 8 and the storage tube 7, thereby enhancing the stability of the buffer rod 8 when it drives the fixed plate 10 and the positioning plate 11 to move.

[0025] In a preferred embodiment, the buffer rod 8 has a cylindrical structure. One end of the buffer rod 8 located inside the storage tube 7 is fixedly connected to a baffle plate. The baffle plate has a circular structure and its dimensions are compatible with the inner cavity of the storage tube 7. The main spring is sleeved on one end of the buffer rod 8 located inside the storage tube 7, while the other end of the buffer rod 8 has a threaded structure.

[0026] In this embodiment, as Figure 3 and Figure 4The dimensions of the baffle and the inner cavity of the storage tube 7 are matched, which can help enhance the stability of the buffer rod 8 when it moves. When the buffer rod 8 moves, the baffle can help squeeze the main spring connected to the buffer rod 8, so that the buffer rod 8 can automatically reset under the action of the squeezed main spring when there is no external force. This allows the buffer rod 8 to drive the fixing plate 10 and the positioning plate 11 to reset synchronously, and then the positioning plate 11 performs secondary positioning of the spacer paper body 3.

[0027] In a preferred embodiment, the adjusting sleeve 9 has a cylindrical structure and an I-shaped cross-section. The inner cavity of the adjusting sleeve 9 has a threaded structure, and the adjusting sleeve 9 is screwed to the buffer rod 8 through the threaded structure. Multiple sets of protrusions are uniformly fixedly connected to the outer arc surfaces at both ends of the adjusting sleeve 9. The multiple sets of protrusions are all hemispherical in shape. At the same time, the size of the through hole at the middle of the adjusting sleeve 9 and the lower end of the fixing plate 10 is compatible, and the fixing plate 10 has a rectangular structure.

[0028] In this embodiment, as Figure 3 and Figure 4 The adjustment sleeve 9 allows the fixed plate 10 and the positioning plate 11 to move relative to the buffer rod 8, thereby assisting in adjusting the position of the positioning plate 11 on the surface of the storage box 1. This enables the fixing mechanism to position and fix the spacer paper body 3 of different sizes. At the same time, the protrusions on the outer side of the adjustment sleeve 9 can help reduce the chance of the worker's hand slipping when rotating. Moreover, the size of both ends of the adjustment sleeve 9 is larger than the size of the through hole, so the adjustment sleeve 9 can rotate flexibly at the lower end of the fixed plate 10, and the adjustment sleeve 9 can drive the fixed plate 10 to move synchronously.

[0029] In a preferred embodiment, the positioning plate 11 has a rectangular structure and an F-shaped end face. Two sets of guide holes are symmetrically opened on the upper surface of the positioning plate 11. A set of guide rods 12 are slidably connected in each of the two sets of guide holes. The upper ends of the two sets of guide rods 12 are fixedly connected to the lower surface of the fastening plate 13. The fastening plate 13 has a rectangular structure, and a fastening layer is fixedly connected to the end of the lower surface of the fastening plate 13 away from the guide rods 12. At the same time, a buffer groove 15 is opened on the upper surface of the storage box 1 at a position corresponding to the guide rods 12. The buffer groove 15 has a square structure.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4The positioning plate 11 is designed to enhance the clamping and fixing effect of the fastening plate 13 on the spacer paper body 3. The size of the guide hole and the guide rod 12 are matched to enhance the stability of the fastening plate 13 when it moves. The fastening layer enhances the contact effect of the fastening plate 13 on the spacer paper body 3. The screw block structure fixedly connected to the upper end of the main screw 14 enhances the stability of the main screw 14 when it rotates. The opening of the storage slot 6 effectively prevents the main screw 14 from interfering with the stacking of the storage box 1.

[0031] The spacer fixing mechanism for liquid crystal glass substrates of this utility model, through the cooperation of the storage cylinder 7, buffer rod 8, main spring, adjusting sleeve 9, fixing plate 10, positioning plate 11, main screw 14 and fastening plate 13, enables the mechanism to fix the spacer body 3 accordingly, thereby ensuring that the spacer body 3 can always adhere to the surface of the liquid crystal glass substrate, ensuring the quality of the liquid crystal glass substrate during transportation and storage. Moreover, through the cooperation of the fitting groove 5, limiting plate 4 and storage groove 6, it can also help enhance the stability of the liquid crystal glass substrate during stacking and help reduce production costs.
