Description

Technical Field

[0001] The utility model relates to an ultrasonic cleaning device for a liquid crystal display screen, belonging to the technical field of liquid crystal display screen cleaning. Background Art

[0002] Liquid crystal displays (LCDs) are a type of display used in digital watches and many portable computers. LCDs use two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid causes the crystals to rearrange, preventing light from passing through them. Thus, each crystal acts like a Venetian blind, allowing light to pass through and blocking it. Liquid crystal displays (LCDs) are currently being developed to be lighter, thinner, shorter, and smaller in size.

[0003] For example, CN207681104U discloses an ultrasonic cleaning device for liquid crystal display production. By combining a cleaning liquid storage device, a discharge plate, and a leak hole, the device achieves a maximum cleaning effect by fixing the discharge plate on both sides of the cleaning liquid storage device and providing a leak hole on the right inner wall of the discharge plate to clean the water storage device. However, after cleaning the display glass panel, a certain amount of moisture will remain on the surface of the glass panel, making it difficult to quickly proceed to the next step of processing, thereby affecting production efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-4 , the utility model provides a technical solution:

[0024] An ultrasonic cleaning device for a liquid crystal display comprises a cleaning box 1, wherein a support rod 2 is fixedly connected to one side of the outside of the cleaning box 1, a servo motor 3 is provided at the top of the support rod 2, a screw rod 4 is connected to the output end of the servo motor 3, a threaded slider 5 is externally connected to the screw rod 4, one end of the threaded slider 5 is fixedly connected to a connecting rod 6, a pull rod 7 is fixedly connected to one side below the connecting rod 6, the bottom of the pull rod 7 is fixedly connected to a support plate 8, a mounting plate 9 is fixedly connected to the bottom of the support plate 8, a plurality of positioning screws 10 are fixedly connected to the inside of the mounting plate 9, and a mounting plate 2 11 is connected to one side below the positioning screw 10.

[0025] Specifically, an ultrasonic transducer 12 is provided on one side below the cleaning box 1. The ultrasonic transducers 12 are grouped into two groups and are symmetrically arranged on both sides of the cleaning box 1. A fan box 13 is provided above the ultrasonic transducer 12. A blower 14 is provided inside the fan box 13. An electric heating wire mesh 15 is provided on one side of the blower 14. An air outlet 16 is provided above the fan box 13. The blower 14 can blow hot air to the glass panel through the electric heating wire mesh 15, so that the moisture on the surface of the glass panel can be quickly dried, and the glass panel can be quickly put into subsequent processing after cleaning, saving the time waiting for the glass panel to dry.

[0026] Specifically, the threaded slider 5 is rectangular, and the threaded slider 5 is slidably connected inside the support rod 2. The length and width of the support plate 8 are the same as the length and width of the inner diameter of the cleaning box 1. The support plate 8 is slidably connected inside the cleaning box 1. The threaded slider 5 can drive the connecting rod 6, the pull rod 7, the support plate 8, the mounting plate 1 9 and the mounting plate 2 11 to move up and down, thereby driving the glass panel to move into or out of the cleaning box 1.

[0027] Example 2: Please refer to Figure 3 The difference between this embodiment and embodiment 1 is that: both the mounting plate 1 9 and the mounting plate 2 11 are provided with a rubber pad 17, and a plurality of clamping grooves 18 are opened on the rubber pad 17. The mounting plate 1 9 and the mounting plate 2 11 have the same size, and the mounting plate 2 11 is slidably connected to the outside of the positioning screw 10. The positioning screw 10 is provided with a threaded bracket 19 on the outside, and the threaded bracket 19 is arranged under the mounting plate 2 11. The rubber pad 17 can prevent the mounting plate 1 9 and the mounting plate 2 11 from directly pressing on the glass panel and causing damage to the glass panel. The upper and lower edges of the glass panel can be snapped into the clamping grooves 18, which is convenient for clamping and fixing the glass panel. Rotating the threaded bracket 19 can drive the mounting plate 2 11 to move up and down to adjust the position, thereby facilitating the clamping and fixing of glass panels of different sizes.

[0028] The working principle of the utility model is as follows: when in use, first rotate the threaded bracket 19. When the threaded bracket 19 rotates on the positioning screw 10, it can drive the mounting plate 2 11 to move up and down. When the distance between the clamping groove 18 in the rubber pad 17 on the mounting plate 1 9 and the mounting plate 2 11 is the same as the height of the glass panel, the glass panel is inserted into the clamping groove 18 in sequence. Finally, tighten each threaded bracket 19 to fix the glass panel between the mounting plate 1 9 and the mounting plate 2 11. Then start the servo motor 3. When the servo motor 3 drives the screw rod 4 to rotate, it can drive the threaded slider 5 to move downward, thereby driving the connecting rod 6, the pull rod 7, the support plate 8 and the glass panel to move downward. When the glass panel is completely immersed in the cleaning liquid, the ultrasonic wave emitted by the ultrasonic transducer 12 cleans the glass panel. After cleaning is completed, start the servo motor 3 again, move the glass panel upward to the side of the blower 14 and start the blower 14 and the electric heating screen 15. The blower 14 blows hot air to the glass panel through the electric heating screen 15, so that the glass panel can be dried.
