Description

Technical Field

[0001] This utility model relates to the field of display glass dispensing technology, specifically to an LCD glass dispensing device. Background Technology

[0002] LCD glass is the core component of liquid crystal displays, mainly used to control the arrangement of liquid crystal molecules to achieve image display.

[0003] A search revealed a patent publication with publication number CN222642399U, which describes a dispensing device for display glass production. Specifically, it involves: "A machine body, with a dispensing head installed on the inner bottom side of the machine body. In this invention, the user grips the handle, pulling the base so that the slider separates from the base via a magnetic block. After separation, the base slides along the slider to the outside of the machine body. The display glass is then placed on a placement block inside the base. After placement, a person rotates the connecting block 180° via a pivot. After rotation, the fixing bolt is twisted, causing it to move downwards in the connecting block via a threaded drive. The bottom protective sleeve then abuts against the display glass, securing it. After securing, the base is pushed, causing it to slide along the slider into the machine body. Simultaneously, the slider is secured to the base via a magnetic block, thus completing the installation of the display glass and enabling better installation and fixation of the display glass."

[0004] Based on the search of the aforementioned patent technologies, we found that the technical solution still has certain defects in use. On the one hand, it is inconvenient to install the display glass, requiring the rotation of multiple connecting blocks to facilitate the stability of the display glass, which is not convenient to operate. Furthermore, it is inconvenient to remove the glued display glass from the placement block inside the base afterward. On the other hand, since the glued display glass needs to be transferred to the subsequent processing stage, it means that after each display glass is glued, it needs to be removed from the base for individual transfer, which causes cumbersome operation and low efficiency.

[0015] 1. In this application, through the design of the square groove, clamping components and other structures, the LCD glass to be glued can be easily placed into the square groove to achieve the positioning effect. With the automatic clamping of the clamping components, the LCD glass can be made stable in the square groove, which facilitates glue application. This method of stabilizing the positioning of LCD glass is simpler and more convenient to operate. At the same time, since the square groove is a hollow structure, it is convenient to push the LCD glass upward from the bottom of the carrier plate, thereby making it easy to remove the LCD glass from the square groove.

[0016] Second, in this application, through the designed carrier plate, multiple square slots, and clamping components, multiple LCD glass pieces requiring adhesive can be placed simultaneously in the multiple square slots of the carrier plate. After adhesive dispensing, multiple LCD glass pieces can be transferred together to subsequent processing stages via the carrier plate. During the transfer process, the LCD glass pieces are always clamped, ensuring their stability during transfer. Due to the carrier plate forming the support, multiple LCD glass pieces can also be directly fed into subsequent processing stages for processing, thus avoiding the problem of frequent disassembly and reassembly of LCD glass pieces on the support during processing. This method can achieve batch adhesive dispensing and batch transfer, making operation more convenient and improving production efficiency. Attached Figure Description

[0025] 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 protection scope of the present utility model.

[0026] Please see Figure 1-6 An LCD glass dispensing device includes a fixed platform 1, a positioning seat 2 fixed at the center of the top of the fixed platform 1, and sliding grooves 201 on both sides of the inner wall of the positioning seat 2. Rotating rollers 202 are rotatably connected to the sliding grooves 201 at equal intervals. The sliding grooves can position a carrier plate 9, define its sliding trajectory, and ensure its limiting effect. The rotating rollers 202 in the sliding grooves 201 can improve the smoothness of the carrier plate 9 during movement. The carrier plate 9 is slidably connected between the two sliding grooves 201 of the positioning seat 2, and the surface of the carrier plate 9 is... Square slots 901 are evenly spaced, and support blocks 902 are fixed to the bottom of both sides of the inner wall of each square slot 901. Positioning holes 15 are equally spaced on the front and back of the carrier plate 9. A cavity 12 is opened inside the positioning seat 2 near the middle of each slide 201. A return spring 13 is fixed inside the cavity 12. A positioning head 14 is fixed at one end of the return spring 13, which moves through the cavity 12 and engages with the positioning hole 15. A clamping assembly is provided on the top of each support block 902.

[0027] Please see Figure 3 , Figure 5 and Figure 6 In this embodiment, each clamping assembly includes three return springs 17, three movable rods 18, and a limiting plate 19. The interior of the carrier plate 9 and the position corresponding to each clamping assembly are provided with three cavities 16. The three return springs 17 are fixed to the inner walls of the three cavities 16. One end of the three movable rods 18 is fixed to the three return springs 17, and the other end of the three movable rods 18 moves through the cavity 16 and is fixed to the limiting plate 19. Silicone strips are glued to the side of the two limiting plates 19 inside each square groove 901 that are close to each other.

[0028] Specifically, when the LCD glass to be glued is placed in the square groove 901, it can be supported by the support block 902. With the help of the limiting plate 19 and the second reset spring 17, the restoring force provided by the second reset spring 17 can clamp the limiting plate 19 on the side of the LCD glass, thereby locking the LCD glass in the square groove 901 and ensuring stability during glue dispensing. The silicone strip on the limiting block 19 can provide good flexibility when in contact with the LCD glass, avoiding pinching or scratching.

[0029] Please see Figure 2 , Figure 3 and Figure 6 In this embodiment, three sets of square grooves 901 are provided on the carrier plate 9, with two in each longitudinal direction forming a set. The three positioning holes 15 on the front and the three positioning holes 15 on the back of the carrier plate 9 correspond to the three sets of square grooves 901 respectively.

[0030] Specifically, when the carrier plate 9 moves to the designated position, that is, when one of the sets of square slots 9 on the top of the carrier plate 9 corresponds to the position of the positioning seat 2, the positioning hole 15 on the side of the carrier plate 9 will correspond to the positioning head 14, and the positioning head 14 will spring back and engage in the positioning hole 15 under the restoring action, thereby achieving a stable positioning effect for the carrier plate 9 and also achieving a position feedback effect, which facilitates glue dispensing. The multiple sets of square slots 901 can facilitate the simultaneous installation of multiple LCD glass for glue dispensing, improving efficiency.

[0031] Please see Figure 1 , Figure 2 and Figure 5In this embodiment, support plates 3 are fixed on both sides of the top of the fixed platform 1, and fixed plates 5 are fixed on both sides of the top between the two support plates 3. A servo motor 6 is installed on one of the fixed plates 5. The power output shaft of the servo motor 6 passes through the fixed plate 5 and is connected to a lead screw 601. The other end of the lead screw 601 is rotatably connected to the other fixed plate 5. A sleeve block 701 is threaded on the rod of the lead screw 601. A movable plate 7 is fixed at the bottom of the sleeve block 701. Limiting grooves 4 are opened on the side of the support plate 3 and at the position corresponding to the movable plate 7. The front and rear sides of the movable plate 7 are respectively limited and slidably connected in the two limiting grooves 4.

[0032] Specifically, by starting the servo motor 6, the lead screw 601 can be driven to rotate. When the lead screw 601 rotates, it can drive the sleeve block 701, which is threaded onto it, to move. This causes the movable plate 7 to slide between the two support plates 3. When the movable plate 7 moves, it can drive the dispensing head 10 at its bottom to slide laterally, thereby adjusting the lateral position of the dispensing head 10 and facilitating dispensing at different positions on the LCD glass.

[0033] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, a servo motor 2 11 is also installed on the front of the movable plate 7. A movable groove is opened at the bottom of the movable plate 7. The power output of the servo motor 2 11 passes through the movable groove and is connected to the lead screw 2 1101. A movable block 2 1102 is slidably connected in the movable groove on the lead screw 2 1101. A dotted head 10 is installed at the bottom of the movable block 2 1102.

[0034] Specifically, by starting the servo motor 11, the lead screw 1101 can be driven to rotate, which in turn drives the movable block 1102, which is threaded onto it, to slide in the movable groove. This allows the dispensing head 10 at the bottom of the movable block 1102 to move longitudinally, thereby adjusting the longitudinal position of the dispensing head 10 and facilitating dispensing of adhesive to different positions on the LCD glass.

[0035] Please see Figure 1 and Figure 5 In this embodiment, a glue tank 8 is also provided on the back of the fixed platform 1, a pump body is provided on the top of the glue tank 8, and a hose is connected to the output end of the pump body. The end of the hose away from the glue tank 8 is connected to the dispensing head 10.

[0036] Specifically, when the pump is started, the adhesive in the adhesive tank 8 can be transported to the dispensing head 10 through the hose, which facilitates the dispensing operation. The top of the adhesive tank 8 is also equipped with a sealing cover, which makes it easy to clean the adhesive tank 8 later and to add adhesive to the adhesive tank.

[0037] When in use, the LCD glass that needs to be glued is placed in multiple square grooves 901 in sequence. When it is placed, the limiting plate 19 in the square groove 901 can fit against the side of the LCD glass. The return spring 17 can clamp and stabilize the LCD glass.

[0038] Then, the carrier plate 9 is placed at the positioning seat 2, so that the two sides of the carrier plate 9 are placed into the two sliding grooves 201. Then, the carrier plate 9 is pushed. The carrier plate 9 moves smoothly by the rolling of the rotating roller 202. After the carrier plate 9 is pushed a certain distance, the positioning hole 15 on the far left of the front and back of the carrier plate 9 will cooperate with the positioning head 14. That is, the positioning head 14 is engaged in the positioning hole 15 by the rebound action of the return spring 13. This can not only realize the feedback of the position of the carrier plate 9, but also provide a certain stabilizing effect for the carrier plate 9. Then, the servo motor 1 6 and the servo motor 2 11 are started. The servo motor 1 6 can drive the dispensing head 10 to move laterally, and the servo motor 2 11 can drive the dispensing head 10 to move longitudinally, so that the dispensing head 10 can be used to dispense glue on the LCD glass.

[0039] After the LCD glass in the two square slots 901 on the left side of the carrier plate 9 is glued, continue to push the carrier plate 9 so that the two square slots 901 in the middle of the carrier plate 9 can drive the LCD glass to be glued. When the carrier plate 9 is moving, the positioning hole 15 in the middle of the front of the carrier plate 9 will engage with the positioning head 14, so that it is convenient to glue the two LCD glass in the middle of the carrier plate 9. Afterwards, the same method can be used to push the carrier plate 9 to glue the two LCD glass on the top right side of the carrier plate 9.

[0040] After all the LCD glass on the carrier plate 9 has been glued, the staff can remove the carrier plate 9 and use it to transfer the glued LCD glass. Alternatively, multiple LCD glass can be sent to the subsequent processing stage for direct processing through the carrier plate 9.

[0041] It should be noted that, for greater convenience and practicality, multiple carrier plates 9 can be prepared simultaneously. After the LCD glass on one carrier plate 9 has finished dispensing, it can be transferred, and then another carrier plate 9 can be taken and placed on the LCD glass for dispensing on this device. By using multiple carrier plates 9 in combination, the dispensing efficiency can be effectively improved.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
