Description

Technical Field

[0001] This utility model relates to the field of LCD panel edge grinding technology, and in particular to a liquid crystal panel edge grinding water blowing mechanism. Background Technology

[0002] LCD monitors are common display tools in daily life and work, and the LCD panel is a crucial component. During the production process, LCD panels require cutting. After cutting, the edges of the LCD panel need to be ground smooth to prevent the sharp edges from scratching people or objects, and to eliminate internal stress on the glass edges, preventing cracks and chipped corners caused by stress, thus reducing production efficiency. Edge grinding is a high-temperature, high-friction process that requires spraying water onto the LCD panel. After grinding, the LCD panel often retains a significant amount of moisture, which needs to be removed; otherwise, it will affect subsequent work processes.

[0003] The patent, with publication number "CN213288051U", is titled "A Water-blowing Mechanism for Edge Grinding of a Liquid Crystal Panel". It includes a fixed bracket, a support plate installed at the lower end of the fixed bracket, and an L-shaped fixing rib fixed on the right side of the support plate. The L-shaped fixing rib includes a horizontal fixing rib and a vertical fixing rib. The horizontal fixing rib is vertically fixed to the support plate. Both the horizontal and vertical fixing ribs are telescopic plate-like structures. The horizontal fixing rib and the vertical fixing rib are hinged together. The vertical fixing rib can rotate along the horizontal fixing rib. A fixed manifold is connected to the lower end of the vertical fixing rib. Air inlet pipes are connected to both ends of the fixed manifold. Several air nozzles are connected to the lower end of the side wall of the fixed manifold. The openings of the air nozzles face away from the fixed manifold, and the air nozzles can spray high-pressure air.

[0004] The aforementioned device blows water onto the surface of the LCD panel using a jet nozzle, but there is a problem that the angle between the high-speed airflow and the LCD panel cannot be adjusted, and it cannot be changed in conjunction with the forward direction of the LCD panel passing under the water blowing mechanism, thus limiting the installation location. Utility Model Content

[0005] The purpose of this utility model is to provide a water blowing mechanism for grinding edges of liquid crystal panels, which can change the direction of the airflow blown by the water blowing mechanism, thereby adjusting according to the forward direction of the liquid crystal panel in the conveying mechanism, and increasing the selectable position when installing the water blowing mechanism.

[0006] To achieve the above objectives, a liquid crystal panel edge grinding and blowing mechanism is provided, including a telescopic mechanism, one side of which is fixedly connected to a blowing mechanism. The blowing mechanism consists of a mounting frame, a rotating shaft, a fixed frame, a connecting pipe, and blowing heads. Both the mounting frame and the fixed frame are U-shaped structures, with the fixed frame housed within the mounting frame. The mounting frame is fixedly connected to the telescopic mechanism. The rotating shaft is housed within the mounting frame, with both ends passing through the mounting frame and the fixed frame for rotatable connection. The rotating shaft is rotatably connected to the mounting frame and fixedly connected to the fixed frame. The connecting pipe is fixedly connected to the fixed frame, with both ends passing through it. Several blowing heads are provided, equidistantly fixedly connected to the end of the fixed frame away from the mounting frame. One end of each blowing head passes through the fixed frame and communicates with the connecting pipe. A connecting plate is fixedly connected to the middle of the end of the rotating shaft away from the fixed frame, and the connecting plate cooperates with the telescopic mechanism. This mechanism can change the direction of the airflow from the blowing mechanism, thereby adjusting it according to the forward direction of the liquid crystal panel in the conveying mechanism, increasing the selectable positions for the blowing mechanism during installation.

[0007] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, the telescopic mechanism consists of a guide rail, a slider, and a cylinder. The slider is disposed on the surface of the guide rail and slidably connected to it. The mounting bracket is disposed at the end of the slider away from the guide rail. The cylinder is fixedly connected to the middle of the end of the slider away from the guide rail, and a connecting frame is fixedly connected to the output end of the cylinder. A connecting plate is disposed in the connecting frame and rotatably connected to the connecting plate. A limit groove is formed in the middle of the end of the telescopic mechanism facing the slider. The cylinder pushes or pulls the connecting plate through the connecting frame, causing the rotating shaft to drive the mounting bracket to rotate. The guide rail and slider cooperate to change the height of the blowing mechanism.

[0008] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, both ends of the connecting pipe are respectively flanged and fitted with sealing caps. The sealing caps are used to seal the open ends of the connecting pipe.

[0009] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, two blowing mechanisms are connected by a mounting bracket when they cooperate. Each blowing mechanism has a threaded hole on its surface for connecting the two mechanisms, and a connecting bolt is installed in the threaded hole. The connecting pipe flanges of the two blowing mechanisms are connected. This allows the number of blowing mechanisms to be increased according to the width of the liquid crystal panel, and enables a cylinder to simultaneously control multiple blowing mechanisms through one mechanism.

[0010] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, the cylinder has symmetrical connecting screws on both sides, and the connecting screws are fixedly connected to the slider. The slider is fixedly connected to the mounting bracket by connecting bolts. The fixing of the mounting bracket by the connecting screws facilitates the disassembly of the blowing mechanism.

[0011] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, a locking bolt is installed at the end of the slider away from the guide rail, and the locking bolt passes through the slider and is threadedly connected to the slider. The end of the locking bolt passing through the slider extends into a limiting groove. The locking bolt is used to fix the slider after adjustment, preventing the slider from moving downwards due to gravity when the blowing mechanism is working.

[0012] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, sealing rings are bonded to both ends of the connecting tube. The sealing rings enhance the sealing performance between the sealing cap and the connecting tube, or between the connecting tubes in two connected blowing mechanisms.

[0013] According to the aforementioned liquid crystal panel edge grinding and blowing mechanism, the end of the blowing head away from the connecting pipe has a flat structure. The flat structure increases the width of the airflow when it exits the blowing head.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The cylinder pulls the connecting plate through the connecting bracket, which causes the rotating shaft to drive the mounting bracket to rotate, thereby changing the direction and angle of the airflow blown out by the blow head.

[0016] 2. The sealing caps at the ends of the connecting bolts and connecting pipes allow the water blowing mechanism to be added according to the width of the LCD panel, thus improving the practicality of the device.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The cylinder 7 pushes or pulls the connecting plate 16 through the connecting bracket 6, causing the rotating shaft 11 to drive the mounting bracket 10 to rotate. The guide rail 3 and the slider 4 cooperate to change the height of the blowing mechanism 2.

[0028] The two ends of the connecting pipe 13 are respectively connected to sealing caps 15 by flanges. The sealing caps 15 are used to seal the open ends of the connecting pipe 13.
