[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Reference Figures 1 to 5 A dispensing device for LCD screen processing includes a base 1; wherein the base 1 is in a fixed state, providing a stable support platform for the positioning component 2 and the adjustment component 3.

[0028] And, the positioning component 2 includes a fixed seat 26 fixedly connected to the outside of the base 1, an adjusting seat 27 disposed on the end face of the fixed seat 26, and a clamping block 28 disposed on the end face of the adjusting seat 27; wherein, the fixed seat 26 has a space inside for the rotating shaft 25 to rotate, the adjusting seat 27 is composed of three arc blocks, and the clamping block 28 is designed in three parts and is installed on the adjacent sides of two adjacent adjusting seats 27, and the liquid crystal display screen is positioned and clamped by the clamping blocks 28 distributed in a ring.

[0029] The adjusting component 3 includes a screw 34 arranged in a ring, a dispensing machine 38 disposed outside the positioning component 2, and connecting blocks 39 fixedly connected to the end face of the dispensing machine 38 and arranged in a ring array. The screw 34 is designed in three groups, forming a specific shape to ensure the lifting range of the sliding block 36. The dispensing machine 38 is a prior art technology, with the adhesive entering from the upper end face of the dispensing machine 38 to achieve the dispensing effect. The connecting blocks 39 are in three groups arranged in a ring, corresponding to each group of adjusting components 3.

[0030] Specifically, the positioning component 2 also includes a first motor 21 fixedly mounted on the upper surface of the base 1 and a rotating shaft 25 rotatably connected to the inner wall of the fixed seat 26. The output end of the first motor 21 is fixedly connected to a drive shaft 22. The first motor 21 provides power input to the positioning component 2 and provides driving force for the clamping or opening of the three clamping blocks 28.

[0031] Furthermore, a first bevel gear 23 is fixedly connected to the outer wall of the drive shaft 22, and a second bevel gear 24 is fixedly connected to the lower end face of the rotating shaft 25. The first bevel gear 23 and the second bevel gear 24 are meshed together. The driving direction of the first motor 21 is changed by the first bevel gear 23 and the second bevel gear 24.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The outer wall of the clamping block 28 is fixedly connected to a rotating shaft 29, and the end face of the rotating shaft 29 is rotatably connected to the outer wall of the adjusting seat 27. The outer wall of the rotating shaft 25 is threadedly connected to an adjusting bushing 212. The clamping block 28 has an L-shaped structure design, and the rotating shaft 29 allows the clamping block 28 to have a certain range of motion, realizing the clamping and opening of the display screen.

[0033] Specifically, an adjusting disc 210 is fixedly connected to the outer wall of the adjusting bushing 212. A groove 211 is formed on the end face of the adjusting disc 210, and the end of the clamping block 28 is embedded in the inner wall of the groove 211. The groove 211 on the end face of the adjusting disc 210 allows the clamping block 28 to be engaged with the groove 211, which converts the lifting and lowering of the adjusting disc 210 into the moving power of the clamping block 28.

[0034] Reference Figure 1 , Figure 5 and Figure 6 The adjustment assembly 3 also includes a guide rod 31 fixedly connected to the upper surface of the base 1. A fixing plate 32 is fixedly connected to the upper surface of the guide rod 31, and a second motor 33 is fixedly installed at the output end of the fixing plate 32. The guide rod 31 on each side of the base 1 is designed in two sets. The guide rod 31 not only supports the fixing plate 32 but also ensures that the sliding block 36 always slides in the vertical direction.

[0035] Specifically, the output end of the second motor 33 is fixedly connected to the outer wall of the lead screw 34. A sliding block 36 is threadedly connected to the outer wall of the lead screw 34, and a sliding ring 35 is fixedly connected to the end face of the sliding block 36. The sliding ring 35 is slidably connected to the outer wall of the guide rod 31. The number of second motors 33 is the same as that of the lead screw 34, providing power input for the rotation of the lead screw 34. The adjustment structure for each position is driven by a separate second motor 33, thus allowing sufficient flexibility in the movement direction of the dispensing machine 38 to meet the dispensing needs of different positions. The lifting and lowering action of the lead screw 34 is achieved through the threaded transmission between the sliding block 36 and the lead screw 34, and the sliding direction of the sliding block 36 is ensured by the sliding of the sliding ring 35 on the outer wall of the guide rod 31.

[0036] Furthermore, both the sliding block 36 and the connecting block 39 have a connecting shaft 310 rotatably connected to their outer walls. A fixing frame 311 is fixedly connected to the end face of the connecting shaft 310, and a connecting post 312 is fixedly connected to the outer wall of the fixing frame 311. The connecting posts 312 on both sides are connected by a connecting rod 37. The outer walls of both the sliding block 36 and the connecting block 39 have the same structure: the two ends of the connecting shaft 310 are fixedly connected to the fixing frame 311, and the connecting posts 312 on both sides of the outer walls of the sliding block 36 and the connecting block 39 are connected by a connecting rod 37. This allows the connecting rod 37 to transmit the moving force of the sliding block 36 to the corresponding position of the connecting shaft 310 on the outer wall of the dispensing machine 38, causing a corresponding rotational movement.

[0037] Working principle: The LCD screen to be glued is placed inside multiple adjustment seats 27. The first motor 21 is started, which drives the drive shaft 22 to rotate. The drive shaft 22 drives the first bevel gear 23 to rotate, which in turn drives the second bevel gear 24 to rotate synchronously. The rotational force of the first motor 21 is converted into the rotational power of the rotating shaft 25. Since the rotating shaft 25 and the adjustment sleeve 212 are threadedly connected and the height of the rotating shaft 25 remains constant, the adjustment sleeve 212 and the adjustment plate 210 move up or down along the outer wall of the rotating shaft 25 during the rotation of the rotating shaft 25. When the adjustment plate 210 moves up and down, it drives the clamping block 28 through the groove 211 on its outer wall. The clamping block 28 is limited and guided by the rotating shaft 29 and rotates around the rotating shaft 29 as the axis. Thus, the top end face of the clamping block 28 in multiple positions contacts the outer wall of the LCD screen to achieve positioning and clamping of the screen, which facilitates the subsequent glue dispensing operation.

[0038] Once the display screen is in a stable position, the second motor 33 is started. The second motor 33 drives the lead screw 34 to rotate. During the rotation of the lead screw 34, the sliding block 36 moves up and down along the outer wall of the lead screw 34. At the same time, the sliding block 36 also drives the sliding rings 35 on both sides to slide synchronously along the guide rod 31, thereby ensuring the certainty of the movement direction of the sliding block 36. The second motor 33 on each side can be driven independently and adjusted according to the dispensing position. After the sliding block 36 moves, the connecting rod 37 drives the connecting column 312 and the connecting shaft 310 to rotate and move synchronously, which in turn drives the dispensing machine 38 to move to different positions to achieve dispensing, improving the dispensing efficiency and applicability of the device.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
