Description

Technical Field

[0001] This utility model relates to the field of LCD screen production technology, and in particular to an adhesive coating device for LCD screen production frame. Background Technology

[0002] LCD screens use liquid crystal material as the basic component, filling the space between two parallel plates with liquid crystal material. By changing the arrangement of molecules inside the liquid crystal material through voltage, the purpose of light blocking and light transmission can be achieved to display images of varying depths and staggered patterns. Moreover, by adding a three-color filter layer between the two plates, color images can be displayed.

[0003] Currently, during the production of LCD screens, adhesive needs to be applied to the frame to bond it together. At present, this is mainly done manually. However, manual adhesive application cannot be evenly applied to the sidewalls, which affects the bonding process. Moreover, LCD screens are usually large and fragile, and they are easily broken during the adhesive application process. After bonding, it is usually necessary to wait for it to dry and set before the next step of production can be carried out, which greatly affects work efficiency. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for applying adhesive to the frame of an LCD screen, comprising:

[0006] The base has four supports fixedly connected to its side wall, and a top plate is fixedly connected to the upper side of the four supports.

[0007] The base is equipped with a clamping and rotating structure, which includes a dual-axis motor fixedly mounted on the upper side of the top plate. Both output shafts of the dual-axis motor are fixedly mounted with drive shafts. Two support plates are fixedly connected to the side wall of the top plate. A bidirectional screw is rotatably connected to the side wall of the two support plates. A bevel gear is fixedly sleeved on the outer side of the bidirectional screw and the drive shaft, and the bevel gears mesh with each other. An upper clamping plate and a lower clamping plate are threadedly connected to the outer side of the bidirectional screw. Multiple fixing rods are fixedly connected to the side wall of the support. The upper and lower clamping plates are slidably connected to the multiple fixing rods. A rotating plate is rotatably connected to the lower side of the upper clamping plate. A telescopic shaft is fixedly connected to the upper side of the rotating plate, passing through the upper clamping plate. A drive motor is fixedly mounted at one end of the telescopic shaft, and the drive motor is fixedly connected to the top plate. A second rotating plate is rotatably connected to the upper side of the lower clamping plate.

[0008] Preferably, a blower structure is installed on the bracket, the blower structure includes a support rod fixedly connected between the brackets, a rotating shaft rotatably connected to the side wall of the support rod, a bevel gear two fixedly sleeved on the outside of the rotating shaft and the bevel gear two meshing with each other, two mounting brackets fixedly connected to the side wall of the bracket, a rotating shaft rotatably connected to the side wall of the two mounting brackets, the rotating shaft and the rotating shaft are connected by a belt pulley assembly, and a fan is fixedly installed on the outside of the rotating shaft.

[0009] Preferably, four movable blocks are slidably connected to one side wall of the rotating plate, and suction cups are slidably connected to the lower side of the four movable blocks. A pressure-reducing spring is fixedly connected between the suction cups and the movable blocks. Multiple suction cups are slidably connected to the upper side of the rotating plate, and a pressure-reducing spring is fixedly connected between each of the multiple suction cups and the rotating plate.

[0010] Preferably, a mounting shell is fixedly sleeved on the outside of the drive motor, and the mounting shell is fixedly connected to the top plate.

[0011] Preferably, a plurality of support columns are fixedly connected to the lower side of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the upper and lower clamping plates are driven by the rotation of the dual-axis motor to clamp the LCD screen, which prevents the movement of the LCD screen during the glue application process from causing uneven glue application or interruption of the glue application. It also eliminates the manual glue application process. Furthermore, the drive motor drives the LCD screen to rotate, which allows the side walls of the LCD screen to be glued separately, eliminating the need for manual rotation of the LCD screen. The whole process is time-saving and labor-saving.

[0014] 2. In this utility model, the rotation of the bidirectional screw drives the air blowing structure to rotate. When the bidirectional screw rotates to clamp the LCD screen, the fan rotates to blow away and clean the dust on the side wall of the LCD screen, avoiding the dust from affecting the adhesive application process. When the clamping is released, the fan continues to rotate to blow and dry the bonded area, which speeds up the fixing time. Attached Figure Description

[0021] Reference Figures 1-5 A device for applying adhesive to the frame of an LCD screen, comprising:

[0022] The base 1 has multiple support columns 28 fixedly connected to its lower side. The support columns 28 support the base 1 and prevent the base 1 from directly contacting the ground. The base 1 has four brackets 2 fixedly connected to its side wall. The top plate 3 is fixedly connected to the upper side of the four brackets 2.

[0023] A clamping and rotating structure is installed on the base 1. The clamping and rotating structure includes a dual-axis motor 4 fixedly installed on the upper side of the top plate 3. Both output shafts of the dual-axis motor 4 are fixedly mounted with drive shafts 5. Two support plates 6 are fixedly connected to the side wall of the top plate 3. A bidirectional screw 7 is rotatably connected to the side wall of the two support plates 6. A bevel gear 17 is fixedly sleeved on the outside of the bidirectional screw 7 and the bevel gear 17 meshes with each other. An upper clamping plate 8 and a lower clamping plate 9 are threadedly connected to the outside of the bidirectional screw 7. Multiple fixing rods 10 are fixedly connected to the side wall of the bracket 2. The upper clamping plate 8 and the lower clamping plate 9 are slidably connected to the multiple fixing rods 10. A rotating plate 11 is rotatably connected to the lower side of the upper clamping plate 8. A telescopic shaft 12 is fixedly connected to the upper side of the rotating plate 11. The telescopic shaft 12 can extend and retract outward. The telescopic shaft 12 can drive the rotating plate 11 to rotate without affecting the up and down movement of the rotating plate 11. The telescopic shaft 12 passes through the upper clamping plate 8. A drive motor is fixedly installed at one end of the telescopic shaft 12. 13. A mounting shell 27 is fixedly sleeved on the outside of the drive motor 13. The mounting shell 27 is fixedly connected to the top plate 3. The mounting shell 27 can fix the drive motor 13 and prevent the output shaft of the drive motor 13 from breaking during operation. A rotating plate 24 is rotatably connected to the upper side of the lower clamping plate 9. Four moving blocks 29 are slidably connected to the side wall of the rotating plate 11. Suction cup 23 is slidably connected to the lower side of the four moving blocks 29. The position of the moving blocks 29 can be changed according to the size of the LCD screen so that the moving blocks 29 correspond to the four corners of the LCD screen, reducing the damage caused by clamping and squeezing. A pressure relief spring 24 is fixedly connected between the suction cup 23 and the moving block 29. Multiple suction cups 25 are slidably connected to the upper side of the rotating plate 24. A pressure relief spring 26 is fixedly connected between the multiple suction cups 25 and the rotating plate 24. Both the pressure relief spring 24 and the pressure relief spring 26 can reduce the pressure on the clamped LCD screen and prevent the LCD screen from breaking during clamping.

[0024] A blower structure is installed on the bracket 2. The blower structure includes a support rod 15 fixedly connected between the brackets 2. A rotating shaft 16 is rotatably connected to the side wall of the support rod 15. A bevel gear 18 is fixedly sleeved on the outside of the double-acting screw 7 and meshes with the bevel gear 18. Two mounting brackets 19 are fixedly connected to the side wall of the bracket 2. A rotating shaft 20 is rotatably connected to the side wall of the two mounting brackets 19. The rotating shaft 20 is connected to the rotating shaft 16 through a pulley assembly 21. The pulley assembly 21 consists of two pulleys and a belt. A fan 22 is fixedly installed on the outside of the rotating shaft 20.

[0025] In this invention, the operator first places the LCD screen horizontally above the lower clamping plate 9. The LCD screen is then fixed in place by the suction cup 25 on the upper side of the lower clamping plate 9. The dual-axis motor 4 is then turned, driving the drive shaft 5 to rotate. The drive shaft 5, through the bevel gear 17, drives the bidirectional screw 7 to rotate. Because the threads on both sides of the bidirectional screw 7 rotate in opposite directions, the rotation of the bidirectional screw 7 causes the upper clamping plate 8 and the lower clamping plate 9, connected by their outer threads, to move closer together until the LCD screen is clamped. During clamping, the suction cups 23 and 25 reduce the clamping force through the pressure-reducing springs 24 and 26 respectively, preventing damage to the LCD screen due to excessive clamping force. Clamping also prevents the LCD screen from moving during the adhesive application process, thus avoiding uneven adhesive application. In the case of intermittent coating, after clamping, by turning on the drive motor 13, the drive motor 13 drives the rotating plate 11 to rotate via the telescopic shaft 12, which in turn drives the LCD screen to rotate, so that the side wall of the LCD screen can be coated separately, eliminating the need for manual rotation of the LCD screen. The whole process is time-saving and labor-saving. When the bidirectional screw 7 rotates, the bidirectional screw 7 can drive the rotating shaft 16 to rotate via the bevel gear 18. The rotating shaft 16 drives the rotating shaft 20 to rotate via the pulley assembly 21. The rotating shaft 20 drives the fan 22 to rotate. The fan 22 blows away and cleans the dust on the side wall of the LCD screen, preventing dust from affecting the coating process. When the clamping is released, the fan 22 rotates again to blow and dry the bonded area, reducing the waiting time for drying and fixing.
