Description

Technical Field

[0001] This utility model relates to the field of LCD screen cleaning technology, specifically to an automatic water blowing device for LCD screen cleaning. Background Technology

[0002] After cleaning the LCD screen, water remains on the surface of the LCD substrate. This water needs to be blown off to prevent water residue from remaining on the LCD steps and causing corrosion during use. However, the current method of blowing water usually involves employees manually controlling an air gun to blow water off the product. Because the air gun is a single-tube blowing device, the blowing area is small and dot-like. Therefore, blowing water off a single product requires repeatedly moving the air gun and blowing the device multiple times. This method is inefficient, labor-intensive, and time-consuming. Each product needs to be manually aligned before operation, which makes it easy to make mistakes. Utility Model Content

[0003] The main purpose of this utility model is to solve the above-mentioned technical problems to a certain extent, and to propose an automatic water blowing device for cleaning LCD screens, which can reduce the labor intensity and operation difficulty of manual water blowing, and at the same time, greatly improve the water blowing efficiency by increasing the air blowing area.

[0004] The above-mentioned problems to be solved by this utility model are achieved through the following technical solution:

[0005] An automatic water-blowing device for cleaning LCD screens is proposed, comprising a main frame, a tray, and a loading seat. The tray is movably mounted on a slide rail on the main frame, and the loading seat is located on the tray. The LCD screen is placed on the loading seat and pushed into a water-blowing chamber inside the main frame along with the tray. The inner wall of the main frame at the water-blowing chamber is provided with a mounting seat. A strip-shaped air pipe is provided on the mounting seat along the length direction of the tray. The strip-shaped air pipe is connected to an air pipe on the main frame, and the air inlet of the air pipe is connected to an external fan. A beveled surface is provided along the length direction of the loading seat. The LCD screen is laid on the beveled surface. A limiting block is provided on the tray. The limiting block abuts against one end of the LCD screen, and the other end of the LCD screen faces the strip-shaped air pipe, so that the LCD screen is tilted.

[0023] like Figure 1-3As shown, this utility model proposes an automatic water-blowing device for cleaning LCD screens, including a main frame 1, a tray 2, and a loading seat 3. The tray 2 is movably mounted on a slide rail provided on the main frame 1. The loading seat 3 is located on the tray 2. The LCD screen is placed on the loading seat 3 and pushed into the water-blowing chamber provided inside the main frame 1 along with the tray 2. The inner wall of the main frame 1 at the water-blowing chamber is provided with a mounting seat 4. The mounting seat 4 is aligned with the length direction of the tray 2 and has a strip-shaped air-blowing pipe 5. The air outlet direction of the strip-shaped air-blowing pipe 5 is set at an angle of 30-45 degrees with the tray 2. A beveled surface is provided along the length direction of the loading seat 3, and the inclination angle of the beveled surface is... The angle of inclination of the strip-shaped air duct 5 is consistent with that of the LCD screen, so that the air outlet direction of the strip-shaped air duct 5 is parallel to the tilt angle of the LCD screen. The LCD screen is laid at an angle on the slanted surface of the cut. A limiting block 6 is provided on the tray 2. The limiting block 6 abuts against one end of the LCD screen, and the other end of the LCD screen faces the strip-shaped air duct 5. The air outlet of the strip-shaped air duct 5 is directly opposite the substrate surface of the LCD screen. The strip-shaped air duct 5 is connected to the air pipe 7 provided on the main frame 1. The air inlet of the air pipe 7 is connected to an external fan. The airflow generated by the fan is transmitted to the strip-shaped air duct 5 through the air pipe 7 and acts on the substrate surface of the LCD screen by the strip-shaped air duct 5.

[0024] In this embodiment, the maximum tilt angle of the beveled surface is 45 degrees, ensuring that the laid LCD screen is also tilted at 45 degrees to guarantee the water blowing effect. This avoids the LCD screen from tipping over when subjected to the air blowing action of the strip-shaped air blower 5 due to an excessively large tilt angle. The tray 2 is provided with fixing rods 8 at the four periphery and the middle position of the loading seat 3, and the fixing rods 8 are inserted into the fixing grooves provided in the loading seat 3 to fix the position of the loading seat 3. In this way, when the loading seat 3 is assembled, its fixing groove is aligned with the corresponding fixing rod 8 and placed in, so that the loading seat 3 can be detachably assembled on the tray 2. This makes it easy to replace the loading seat 3 with different tilt angles of the beveled surface, which can correspond to the tilt angle of the strip-shaped air blower 5, ensuring that the air outlet direction of the strip-shaped air blower 5 is parallel to the tilt angle of the LCD screen.

[0025] In this embodiment, the loading seat 3 is first fixed on the tray 2, and then the cleaned LCD screen is laid at an angle on the slanted surface of the loading seat 3. It is then pushed into the water blowing chamber inside the main frame 1 along with the tray 2. The airflow generated by the blower is transmitted to the strip-shaped air blowing pipe 5 through the air pipe 7, and the strip-shaped air blowing pipe 5 acts on the surface of the LCD screen substrate. The air blowing range of the strip-shaped air blowing pipe 5 can cover all the LCD screens on the loading seat 3, thereby greatly improving the water blowing efficiency by increasing the air blowing area. At the same time, the tilted end of the LCD screen faces the strip-shaped air blowing pipe 5, and the water remaining on the surface of the LCD screen substrate is blown away by the strip-shaped air blowing pipe 5. Compared with manually controlling the air gun to blow water, this device can reduce the labor intensity and operation difficulty of manual water blowing, and save labor costs. After the water blowing work is completed, the tray 2 is pulled out from the main frame 1, and finally the LCD screen is removed.

[0026] In another embodiment, a solenoid valve 9 is provided between the air pipe 7 and the pipe connecting the blower. An infrared sensor 10 installed inside the main frame 1 is electrically connected to the solenoid valve 9. Through this structure, the tray 2 is pushed into the main frame 1. When the infrared sensor 10 senses that the tray 2 has moved to a predetermined position, the solenoid valve 9 receives a signal from the infrared sensor 10 and opens, so that the airflow generated by the blower can be transmitted through the air pipe 7 to the strip-shaped air blowing pipe 5, and act on the surface of the LCD screen substrate by the strip-shaped air blowing pipe 5 (at this time, the air blown out by the strip-shaped air blowing pipe 5 can cover the entire LCD screen). When the tray 2 is pulled out of the main frame 1, the infrared sensor 10 can no longer sense the position of the tray 2, and the solenoid valve 9 receives a signal from the infrared sensor 10 and closes. At this time, the airflow generated by the blower will not be transmitted to the strip-shaped air blowing pipe 5, thus achieving the effect of shutting off the water blowing, realizing the automation of the water blowing operation, and saving labor costs.

[0027] Furthermore, a baffle 11 is provided in the center of the tray 2, and two loading seats 3 are respectively located on both sides of the baffle 11 and are respectively corresponding to the strip-shaped air pipe 5. The baffle 11 blocks the water blown away, preventing it from being blown into the substrate surface of the LCD screen on the same side.

[0028] Furthermore, the tray 2 is provided with a movable groove corresponding to the position of each LCD screen. A screw 12 is movably mounted on the movable groove. A limiting block 6 is mounted on the screw 12. A locking sleeve 13 for pressing the position of the limiting block 6 is provided at the part of the screw 12 that extends out of the limiting block 6. Through this structure, the limiting block 6 can be moved according to the position of the loading seat 3 at different tilt angles of the LCD screen, so that the limiting block 6 abuts against the end of the LCD screen.

[0029] In use, the limiting block 6 and the locking sleeve 13 are assembled on the screw 12. At this time, the locking sleeve 13 is not locked. After the LCD screen is placed on the loading seat 3, the limiting block 6 is pushed and the screw 12 is moved in the movable groove so that the limiting block 6 abuts against the end of the LCD screen. Then the locking sleeve 13 is tightened so that the locking sleeve 13 pulls the limiting block 6 and the screw 12 together, thereby fixing the position of the limiting block 6 and ensuring the support effect for the LCD screen.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
