The upper connecting block 3232 is fixedly connected to the upper side of the annular belt 3213 by bolts, so that when the annular belt 3213 rotates, it can drive the bracket 323 to move in the horizontal direction; the lower connecting block 3232 is provided with a slide groove on the surface of the side close to the horizontal support plate 312, and a horizontal guide rail is arranged in the slide groove. The length direction of the horizontal guide rail is the same as the length direction of the horizontal support plate 312. The horizontal guide rail is fixed on the surface of the horizontal support plate 312 close to the connecting plate 3231 by bolts. When the connecting plate 3231 slides horizontally, the lower connecting block 3232 slides horizontally along the horizontal guide rail through the slide groove.

[0062] Reference Figure 5At this time, after the third motor 722 is powered on and started, the second lead screw 723 will rotate around its own axis under the drive of the third motor 722, and then drive the placement table 73 to slide in the horizontal direction along the horizontal slide rail 71.

[0063] In addition, refer to Figure 4 and Figure 5 In this embodiment, the mounting frame 721 in the second horizontal conveying mechanism 8 is fixed to a horizontal slide rail 71 in the second horizontal conveying mechanism 8 by bolts.

[0064] Reference Figure 1 and Figure 5 After the LCD screen 5 is lifted above the cleaning table 1 by the loading mechanism 3, the loading mechanism 3 will first place the LCD screen 5 on the upper surface of the placement table 73, and then the horizontal sliding drive member 72 drives the placement table 73 to move to the bottom of the plasma cleaning gun 25, waiting for the plasma cleaning gun 25 to clean the LCD screen 5.

[0065] Reference Figure 1 and Figure 4 Moreover, in the present embodiment, when the placement table 73 in the first horizontal conveying mechanism 7 is below the plasma cleaning gun 25, the placement table 73 in the second horizontal conveying mechanism 8 is located at the unloading mechanism 4; on the contrary, when the placement table 73 in the second horizontal conveying mechanism 8 is below the plasma cleaning gun 25, the placement table 73 in the first horizontal conveying mechanism 7 is located at the loading mechanism 3, so that after cleaning one LCD screen 5, another LCD screen 5 can be cleaned immediately, thereby improving the cleaning efficiency.

[0066] Reference Figure 4 and Figure 6 In order to facilitate the cleaning of the LCD screen 5 on the placement table 73 in the first horizontal conveying mechanism 7, an ejection hole is opened on the placement table 73 in the first horizontal conveying mechanism 7, and a vertical ejection mechanism 9 is arranged in the ejection hole. The vertical ejection mechanism 9 is fixed on the cleaning table 1, and the vertical ejection mechanism 9 is used to push up the LCD screen 5 on the same placement table 73 as the ejection hole. At this time, the LCD screen 5 on the placement table 73 in the first horizontal conveying mechanism 7 can be raised to the same height as the LCD screen 5 on the placement table 73 in the second horizontal conveying mechanism 8 for cleaning, and the plasma cleaning gun 25 (refer to Figure 1 ) does not need to repeatedly move up and down in a large range, which is convenient for plasma cleaning gun 25 (refer to Figure 1 ) for more accurate cleaning.

[0067] Specifically, refer to Figure 5 and Figure 6The vertical ejection mechanism 9 includes a cylinder 91 and a top plate 92. The cylinder 91 is fixed to the lower surface of the placement table 73 in the first horizontal conveying mechanism 7 by bolts, and the output rod of the cylinder 91 is vertically arranged; the top plate 92 is fixed to the output rod of the cylinder 91 by bolts and is in the ejection hole; when the LCD screen 5 is on the upper surface of the placement table 73 in the first horizontal conveying mechanism 7, the cylinder 91 pushes up the LCD screen 5 on the placement table 73 in the first horizontal conveying mechanism 7 through the top plate 92, so that the LCD screen 5 on the placement table 73 in the first horizontal conveying mechanism 7 moves to a state flush with the LCD screen 5 on the placement table 73 in the second horizontal conveying mechanism 8, so that the plasma cleaning gun 25 can clean the LCD screen 5.

[0068] Reference Figure 1 and Figure 5 In order to prevent the LCD screen 5 in the cleaning state from changing position at will, in the present embodiment, a limit plate 10 is further horizontally arranged on the cleaning table 1. The limit plate 10 is located between the horizontal conveying mechanism and the plasma cleaning gun 25 in the plasma cleaning mechanism 2. The limit plate 10 is used to press the LCD screen 5 in the cleaning state on the placement table 73. The limit plate 10 is U-shaped as a whole and its opening faces the cleaning table 1. A hollow hole 101 is opened at the bottom of the limit plate 10. The edge of the hollow hole 101 is pressed on the upper surface of the LCD screen 5. The hollow hole 101 leaks the position on the upper surface of the LCD screen 5 that needs to be cleaned, so that the plasma The cleaning gun 25 can clean the position that needs to be cleaned, while the position that does not need to be cleaned is covered and is not easily affected; a push piece 111 for driving the limit plate 10 to move vertically is arranged at the edge of the limit plate 10, and the push piece 111 includes a push cylinder 1112 and a hollow plate 1113, and the push cylinder 1112 is fixed to the hollow plate 1113 by bolts. The hollow plate 1113 is vertically arranged, and the lower end of the hollow plate 1113 is fixed to the upper surface of the cleaning table 1 by bolts. In this embodiment, the push piece 111 is symmetrically arranged, and the hollow plates 1113 in the two push pieces 111 are fixed to the cleaning table 1 by bolts.

[0069] Reference Figure 5Before the placement table 73 in the second horizontal conveying mechanism 8 transports the LCD screen 5 to the bottom of the plasma cleaning gun 25, the pushing cylinder 1112 in the pushing member 111 pushes the limit plate 10 to move upward, so that the limit plate 10 does not affect the movement of the LCD screen 5. After the placement table 73 in the second horizontal conveying mechanism 8 transports the LCD screen 5 to the bottom of the plasma cleaning gun 25, the pushing cylinder 1112 in the pushing member 111 pulls the limit plate 10 downward again, so that the limit plate 10 cooperates with the placement table 73 to press the LCD screen 5. At this time, the LCD screen 5 is not easy to change its position during cleaning. Similarly, after the vertical ejection mechanism 9 lifts up the LCD screen 5 transported by the first horizontal conveying mechanism 7, the limit plate 10 can also cooperate with the vertical ejection mechanism 9 to press the LCD screen 5.

[0070] Reference Figure 1 and Figure 5 After the LCD screen 5 is cleaned, the first horizontal conveying mechanism 7 and the second horizontal conveying mechanism 8 will transport the LCD screen 5 on their respective placement tables 73 to the unloading mechanism 4, and the unloading mechanism 4 will remove the LCD screen 5 from the placement table 73, and then the loading mechanism 3 will place a new LCD screen 5 to be cleaned.

[0071] In this embodiment, the structure of the unloading mechanism 4 is the same as that of the loading mechanism 3 .

[0072] The implementation principle of an LCD plasma cleaning machine in an embodiment of the present application is as follows: before the equipment works, it is first necessary to place a number of stacked LCD screens 5 to be cleaned on a placement platform 6, and then start the loading mechanism 3 to adsorb the LCD screen 5 to be cleaned on the placement platform 6, and move it to the placement table 73 in the first horizontal conveying mechanism 7 or the second horizontal conveying mechanism 8, and then the placement table 73 in the first horizontal conveying mechanism 7 or the second horizontal conveying mechanism 8 is transported to the bottom of the plasma cleaning gun 25, and then the plasma cleaning gun 25 cleans the LCD screen 5 on the placement table 73, and after cleaning, the first horizontal conveying mechanism 7 or the second horizontal conveying mechanism 8 transports the cleaned LCD screen 5 to the unloading mechanism 4, and finally the cleaned LCD screen 5 is transported away from the cleaning table 1 through the unloading mechanism 4.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
