Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display screen bonding technology, and in particular to an auxiliary device for applying adhesive to a liquid crystal display screen. Background Technology

[0002] LCD screens are a type of flat panel display used in televisions and computers. Their advantages include low power consumption, small size, and low radiation. During the manufacturing process, adhesive is applied to bond the display screen and panel, or other components together. Before applying the adhesive, auxiliary devices are often used to fix and position the display screen or other components to be bonded, improving the stability and accuracy of subsequent adhesive application and bonding.

[0003] Currently, most adhesive application auxiliary devices fix the display screen by driving the movement of corresponding clamping plates through multiple electrical components. While this method effectively fixes the display screen, it increases the overall manufacturing cost of the auxiliary device and wastes energy during use. Although some auxiliary devices have the function of fixing the display screen with a single electrical component, these devices often require the electrical component to be constantly started and stopped during use to achieve clamping and unclamping. Although this method reduces energy waste, the frequent start and stop will cause a lot of damage to the electrical components, significantly reducing their service life and making them prone to damage.

[0004] Therefore, it is necessary to provide an auxiliary device for applying adhesive to a liquid crystal display screen to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for applying adhesive to a liquid crystal display screen.

[0009] As a further description of the above technical solution: The top of the adjusting block is provided with a sliding groove, and the clamping positioning plate is slidably connected inside the sliding groove. The sliding groove can guide and limit the clamping positioning plate, thereby improving the stability of the movement of the clamping positioning plate.

[0010] As a further description of the above technical solution: A corrugated telescopic tube is fixedly connected to one side of the inner wall of the chute, and the other end of the corrugated telescopic tube is fixedly connected to one side of the clamping and positioning plate.

[0011] As a further description of the above technical solution: The adjusting assembly includes a threaded rod and an internally threaded sleeve. The threaded rod is rotatably connected to the adjusting block, and the internally threaded sleeve is threadedly connected to the outer surface of the threaded rod.

Detailed Implementation

[0017] 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.

[0018] Reference Figure 1-4This utility model provides an auxiliary device for applying adhesive to a liquid crystal display screen: It includes a housing 1, a controller 11 on the top of the housing 1, four movable slots 2 fixedly formed on the top of the housing 1, adjusting blocks 3 slidably connected inside the movable slots 2, adjusting components and clamping positioning plates 4 on the adjusting blocks 3, a rubber plate 10 fixedly connected to one side of the clamping positioning plate 4, a sliding groove 13 formed on the top of the adjusting blocks 3, and the clamping positioning plate 4 slidably connected inside the sliding groove 13. Four rotating shafts 5 are rotatably connected to the top of the inner wall of the housing 1, and a device box 20 is fixedly installed on the top of the inner wall of the housing 1, rotatably connected to the four rotating shafts 5. Adjusting discs 6 are fixedly fitted onto the outer surfaces of each of the four rotating shafts 5, and semi-circular grooves 7 and arc-shaped grooves 8 are formed on the top of each of the four adjusting discs 6. The semicircular groove 7 and the arc groove 8 are connected. A circular block 9 is slidably connected inside the semicircular groove 7. The top of the circular block 9 is fixedly connected to the bottom of the adjusting block 3. An electrical drive assembly is installed inside the housing 1. Through the arrangement of the housing 1, the moving groove 2, the adjusting block 3, the adjusting plate 6, the semicircular groove 7, the arc groove 8, the circular block 9, the threaded rod 15, the gear 18, and the gear ring 19, after the initial adjustment of the position of the clamping positioning plate 4 according to the size of the display screen, the automatic clamping and unclamping of the display screen can be achieved by a single drive source during the subsequent glue application and bonding process of the display screen of the corresponding size. The motor 17 can also work without stopping, which not only improves energy utilization but also solves the problem of the motor 17 being easily damaged by constant starting and stopping, thereby improving the practicality of the device.

[0019] The top of the chassis 1 is fitted with several ball bearings 12, which are arranged in a rectangular array. The arrangement of the ball bearings 12 reduces the friction between the display screen and the top of the chassis 1, making it easier to adjust the position of the display screen during subsequent clamping.

[0020] A corrugated telescopic tube 14 is fixedly connected to one side of the inner wall of the slide groove 13, and the other end of the corrugated telescopic tube 14 is fixedly connected to one side of the clamping and positioning plate 4. The corrugated telescopic tube 14 can shield the threaded rod 15 and prevent the external environment from affecting the use of the threaded rod 15.

[0021] The adjustment assembly includes a threaded rod 15 and an internal threaded sleeve 16. The threaded rod 15 is rotatably connected to the adjustment block 3, and the internal threaded sleeve 16 is threadedly connected to the outer surface of the threaded rod 15. The internal threaded sleeve 16 is fixedly connected to the clamping and positioning plate 4. By setting the adjustment assembly, the position of the clamping and positioning plate 4 can be easily adjusted according to the size of the display screen, which is convenient for clamping and positioning display screens of different sizes.

[0022] The electrical drive assembly includes a motor 17 and four gears 18. The motor 17 is fixedly installed on the top of the inner wall of the housing 1. A gear ring 19 is fixedly connected to the output end of the motor 17. The four gears 18 are respectively fixedly sleeved on the outer surface of the four rotating shafts 5. The gear ring 19 meshes with the four gears 18. Through the setting of the electrical drive assembly, the four adjusting discs 6 can be driven to rotate synchronously, and the four clamping positioning plates 4 can be moved synchronously in conjunction with the semi-circular groove 7 and the arc groove 8.

[0023] Working principle: When in use, place the display screen on the top of the chassis 1, and adjust the position of the four clamping positioning plates 4 according to the size of the display screen. That is, manually rotate the threaded rod 15, and under the guidance of the slide groove 13, the internal threaded sleeve 16 drives the corresponding clamping positioning plate 4 to move to one side of the display screen until the corresponding rubber plate 10 abuts against the display screen. Similarly, the four rubber plates 10 can abut against the four sides of the display screen to complete the fixing of the display screen. When the display screen is glued and bonded, and it is necessary to unload the material and prevent other display screens of the same size from being glued and bonded, the motor 17 is started, causing its output end to drive the gear ring 19 to rotate. The gear ring 19 drives the four gears 18 to rotate synchronously. The gears 18 drive the corresponding rotating shaft 5 to rotate. The rotating shaft 5 drives the corresponding adjusting plate 6, semi-circular groove 7, and arc groove 8 to rotate. When the circular block 9 moves from the inside of the semi-circular groove 7 to the inside of the arc groove 8, it is pushed to move under the guidance of the semi-circular groove 7 and the arc groove 8. The circular block 9 drives the corresponding adjusting block 3 to move. Under the guidance of the moving groove 2, the adjusting block 3 drives the corresponding threaded rod 15, clamping positioning plate 4, and rubber plate 10. The circular block 9 moves away from the display screen, and at this time, the circular block 9 is located inside the arc groove 8. Moving inside the arc groove 8 releases the clamping and positioning of the display screen, making it easy to remove it and place other display screens of the same size. After the display screen is placed, as the adjusting plate 6 rotates, the circular block 9 moves into the semi-circular groove 7, causing the circular block 9 to drive the adjusting block 3, the clamping and positioning plate 4, and the rubber plate 10 to move closer to the center of the housing 1. With the help of the ball bearing 12, the newly placed display screen can be automatically clamped, fixed, and positioned. Furthermore, as the adjusting plate 6 rotates and the circular block 9 is located inside the arc groove 8, it is easy to apply adhesive and bond the screen, enabling continuous operation of the device.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
