Detailed Implementation

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0021] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0022] See Figure 1-4 The LCD screen cleaning equipment shown includes a base 7 and uprights 1 installed at both ends of the base 7. Two light rods 6 are symmetrically arranged between the two uprights 1. Rodless cylinders 9 are installed on the light rods 6. The two rodless cylinders 9 are connected by a connecting plate 10. Two guide rods 8 are symmetrically arranged on the connecting plate 10. The bottoms of the two guide rods 8 are connected by a mounting plate 13. A telescopic cylinder 11 is installed in the middle of the connecting plate 10. The cylinder shaft of the telescopic cylinder 11 passes through the connecting plate 10 and connects to the mounting plate 13. A water collection tank 14 is installed at the bottom of the mounting plate 13. Multiple nozzles 17 are provided on at least one side of the water collection tank 14. A water inlet 18 communicating with its inner cavity is provided at the end of the water collection tank 14. A placement platform 2 is provided in the middle of the base 7. A positioning groove 3 is provided on the upper end of the placement platform 2. Multiple support blocks 4 are evenly distributed in the positioning groove 3.

[0023] By implementing the above technical solution, during use, the LCD screen to be cleaned is positioned in the positioning groove 3 of the placement platform 2, supported by multiple support blocks 4. Then, the rodless cylinder 9 is activated to move the connecting plate 10 back and forth, adjusting the front and rear rinsing positions of the multiple nozzles 17. Simultaneously, the telescopic cylinder 11 can move the mounting plate 13 vertically, adjusting the height of the multiple nozzles 17. Adjusting the front and rear positions allows for reciprocating rinsing of the LCD screen; adjusting the height of the multiple nozzles 17 adjusts the force of the water spray when it contacts the LCD screen surface, thus adjusting the cleaning intensity; the water collection tank 14 is installed at the bottom of the mounting plate 13 for easy disassembly and replacement. The water forms an impact angle with the cleaning surface, better protecting the LCD screen and preventing it from being subjected to vertical impact forces.

[0024] In this embodiment, multiple recessed slots 5 are provided on both sides of the placement platform 2. The depth of the recessed slots 5 is greater than the depth of the positioning groove 3, and the inner side of the recessed slots 5 extends into the positioning groove 3. The multiple recessed slots 5 facilitate the placement and removal of the LCD screen, and also allow water accumulated in the positioning groove 3 to drain downwards, preventing the bottom of the LCD screen from being submerged in water.

[0025] In this embodiment, a screw is provided at the upper end of the guide rod 8, and a nut 12 is sleeved on the screw. With this arrangement, the guide rod 8 is locked and fixed to the connecting plate 10 by the nut 12.

[0026] In this embodiment, the bottom surface of the mounting plate 13 is provided with a dovetail slot; the upper end of the water manifold 14 is provided with a dovetail strip 15 that is inserted into the dovetail slot. With this arrangement, the mounting plate 13 and the water manifold 14 are assembled together by inserting the dovetail strip 15 into the dovetail slot.

[0027] In this embodiment, the upper end of the dovetail strip 15 is provided with a screw hole; the mounting plate 13 is provided with a screw 21 that is screwed into the screw hole. This arrangement secures the insert-fitting mounting plate 13 to the water tank 14, facilitating replacement and disassembly.

[0028] In this embodiment, inclined surfaces 16 are symmetrically arranged on both sides of the water tank 14, and the nozzles 17 are vertically mounted on the inclined surfaces 16. This arrangement allows the installed nozzles 17 to have an inclined angle, forming a non-right angle with the LCD screen, thus enhancing the cleaning effect. The nozzles 17 employ fan-shaped nozzles, and the cleaning water sprayed from multiple nozzles 17 forms a water curtain. Each nozzle 17 has a built-in solenoid valve, which is controlled by the system to open and close. When multiple nozzles 17 are arranged on both sides, the multiple nozzles 17 on the side of the water tank 14 that are in front are activated.

[0029] In this embodiment, a partition 19 is provided in the middle of the water collector 14, dividing the water collector 14 into two water chambers 20 arranged on the left and right. Each water chamber 20 has a corresponding water inlet 18 at its end. With this arrangement, water can be supplied separately to multiple nozzles 17 on both sides. Water is sent into the water chamber 20 through the independent water inlet 18 and then sprayed out from the nozzle 17 on the corresponding side.

[0030] In this embodiment, the support block 4 is a silicone pillar with a spherical top. This design reduces the support contact area on the bottom surface of the LCD screen, preventing adhesion, and the use of silicone pillar material also helps prevent the bottom surface from being bumped or knocked.

[0031] The LCD screen cleaning equipment of this utility model is suitable for cleaning LCD screens with a certain waterproof rating. After cleaning, an external fan is used to blow away any remaining water stains on the surface. If water enters the LCD screen, it indicates that the LCD screen has a waterproof problem and should be treated as a defective product.

[0032] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0034] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
