The bottom ends of the two positioning frames 6 are rotatably connected to CV support rollers 25 through bearings. A second staggered axis bevel gear 27 is fixed on one side of the CV support roller 25 through the support plate 22. The bottom of the second staggered axis bevel gear 27 is meshed and connected with the first staggered axis bevel gear 24, so that the transmission shaft 23 drives the rotation of the first staggered axis bevel gear 24 to drive the CV support roller 25 to rotate, and at the same time, the CV support roller 25 can rotate stably inside the support plate 22. The top ends of the two positioning frames 6 are slidably connected to positioning blocks 30, so that The positioning block 30 can only slide inside the positioning frame 6, and the two corresponding positioning blocks 30 are rotatably connected with the CV pressing roller 26 through the bearing, so that the CV pressing roller 26 is located on the top of the CV supporting roller 25, and the outer sides of the CV supporting roller 25 and the CV pressing roller 26 are evenly fixed with pressing wheels 33, and the top of the pressing wheel 33 on the outer side of the CV supporting roller 25 is located below the liquid level inside the PVC water-containing inner frame 16, so that the rotation of the CV supporting roller 25 and the CV pressing roller 26 can drive the LCD to move stably through the pressing wheels 33 corresponding to the outer sides of the CV supporting roller 25 and the CV pressing roller 26;

[0043] A fourth transmission gear 29 is fixed to one side of the CV pressure coating roller 26, so that the fourth transmission gear 29 is located between the positioning frame 6 and the support plate 22, and the bottom of the fourth transmission gear 29 is meshingly connected with the third transmission gear 28, and the inner side of the third transmission gear 28 is fixed to the CV support roller 25, and the rotation of the CV support roller 25 can drive the CV pressure coating roller 26 to rotate in the opposite direction through the meshing connection between the third transmission gear 28 and the fourth transmission gear 29, so that the CV support roller 25 and the CV pressure coating roller 26 rotate in the opposite direction, and the object is driven to translate through the outer pressure wheel 33.

[0045] The use process of an LCD immersion pre-cleaning CV component provided by the present invention is as follows: when in use, first allow the product to enter the interior of the PVC protective outer frame 1 from the feed trough 3, and at the same time allow the product to be supported at the bottom by the pressing wheels 33 on multiple CV support rollers 25, and at the same time allow the bottom of the pressing wheel 33 on the CV pressing roller 26 to squeeze the product so that the product is located between the top pressing wheel 33 and the bottom pressing wheel 33, thereby preventing the product from being offset and being normally transported to the designated position, and then through the operation of the water pump in the bottom circulating water tank, the liquid inside the circulating water tank is transported through the water inlet pipe 13 into the inner side of the PVC water-containing inner frame 16 in the PVC protective outer frame 1, and then the water in the cavity inside the PVC water-containing inner frame 16 is stored to a certain position, and when in use. The water inlet pipe 13 is continuously filled with water. When the water level is higher than the CV support roller 25, some water will flow out from the gap and enter the outside of the PVC water-containing inner frame 16 inside the PVC protective outer frame 1. At this time, the water injection amount is ensured to be greater than the overflow amount, and the water level inside the PVC water-containing inner frame 16 can continue to rise to about 5mm above the product. At this time, the product is completely immersed in water to achieve the effect of soaking pre-cleaning. At the same time, water overflowing from the inside of the PVC water-containing inner frame 16 and entering the outside of the PVC water-containing inner frame 16 inside the PVC protective outer frame 1 will continue to flow back from the circulating water drain port 15 to the circulating water tank under the machine to achieve water recycling; when the number of times the circulating water is used reaches the specified value, the water valve at the bottom of the inner cavity drain port 14 is opened to drain the water in the cavity or drain the water through the drain port when the machine is shut down.
