Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass processing, in particular to a grinding mechanism for facilitating material cutting. Background Art

[0002] Liquid crystal glass is a display made using the optical properties of liquid crystals. It is a very thin piece of glass that can display images of different colors. The thickness of this glass sheet is very thin, usually only a few millimeters, but the image displayed is very clear. Liquid crystal glass is often used in electronic devices such as mobile phones, tablets, and televisions. Liquid crystal glass is usually composed of two layers of glass plates with a layer of liquid crystal molecules in the middle. When voltage is applied to the liquid crystal molecules, they change direction, causing light to distort when passing through the liquid crystal glass. This distorted light is reflected on the two layers of glass plates to form different colors and patterns. By controlling the size and direction of the voltage, the display effect of the liquid crystal glass can be adjusted.

[0025] In this embodiment, Figure 3As shown, the limiting mechanism 9 is composed of an air pump b901, an air suction hose 902, a fixed plate 903, and a suction cup b904, wherein the bottom center of the fixed plate 903 is threadedly connected to the driving end of the telescopic rod 8, and one end of the air suction hose 902 is plugged into one side of the bottom of the fixed plate 903, and the other end of the air suction hose 902 is plugged into the air suction port of the air pump b901, and a suction cup b904 is also plugged into the top center of the fixed plate 903; it should be noted that by rotating the motor After the support rod 3 is rotated so that the glass adsorbed by the material taking mechanism 4 is rotated to the top of the limiting mechanism 9, the operator can start the hydraulic cylinder 401 again to extend downward and push the suction cup a405, so that the glass adsorbed by the suction cup a405 is attached to the upper surface of the suction cup b904 placed in the limiting mechanism 9, and then release the adsorption state between the suction cup a405 and the glass, and start the suction pump b901 so that the suction pump b901 can drain the air between the suction cup b904 and the lower surface of the glass through the suction hose 902. The air is completely extracted, so that the suction cup b904 can be firmly vacuum-adsorbed on the lower surface of the glass. At the same time, the hydraulic push rod 10 is started again to push the edge grinding mechanisms 11 on the left and right sides toward the middle glass, until the grinding file 1105 in the edge grinding mechanism 11 is attached to the edge of the glass and performs a grinding operation on it. During this period, the stepper motor 7 plugged into the bottom of the workbench 6 can be started after a pair of side edges of the glass are polished, thereby driving the limiting mechanism 9 provided on the top of the workbench 6 to rotate, thereby rotating the other pair of side edges to the grinding file 1105 for grinding them. When all sides of the entire piece of glass have been polished, the operator can start the telescopic rod 8 to shorten its driving end downward and drive the entire limiting mechanism 9 to move downward until the fixed through plate 903 in the limiting mechanism 9 is flush with the second conveyor belt 1304, and then start the parallel push rod 12 to push forward, and at the same time release the adsorption state between the suction cup b904 and the glass, thereby pushing the glass to the top of the second conveyor belt 1304 to complete the unloading operation.

The sliders 1104 are arranged on the left and right sides of the bottom of the slide rail 1101. The rotating screw rod 1102 is rotatably connected to the inner wall of the left and right sides of the slide rail 1101. The servo motor 1103 is also plugged into one end of the rotating screw rod 1102. The grinding file 1105 is also screwed to the outer wall of the rotating screw rod 1102. It should be noted that after the glass is firmly adsorbed on the upper surface of the suction cup b904 through the vacuum pump b901 and the vacuum hose 902, At this time, the operator can simultaneously start the hydraulic push rods 10 on both sides and push the edge grinding mechanism 11 towards the middle glass until the grinding file 1105 in the edge grinding mechanism 11 is in contact with the edge of the glass. At the same time, the grinding file 1105 can be started to grind the edge of the glass, and the servo motor 1103 can be started at the same time, so that the output end of the servo motor 1103 starts to rotate and drives the rotating screw 1102 connected thereto to rotate all day, and the grinding file 1105 screwed to the outer wall of the rotating screw 1102 will start forward and backward along the inner wall of the slide rail 1101, thereby evenly grinding the entire side of the glass.

[0027] In this embodiment, Figure 1 and Figure 4 As shown, a slide groove 201 is provided on the front and rear sides of the top of the base 2, and a sliding connection is formed with the slider 1104 of the edge grinding mechanism 11 through the slide groove 201; it should be noted that after the glass is firmly adsorbed on the upper surface of the suction cup b904 through the vacuum pump b901 and the vacuum hose 902, the operator can simultaneously start the hydraulic push rods 10 on both sides, so that the driving end thereof begins to extend in the horizontal direction, and pushes the slider 1104 connected thereto along the inner wall of the slide groove 201 toward the middle glass. Because the top of the slider 1104 is provided with a slide rail 1101 and other components of the edge grinding mechanism 11, when the slider 1104 slides along the inner wall of the slide groove 201, the entire edge grinding mechanism 11 will also be driven to approach the middle glass, until the grinding file 1105 in the edge grinding mechanism 11 is attached to the edge of the glass, thereby completing the grinding of the glass edge by the grinding file 1105.

[0028] The use method and advantages of the utility model: When the grinding mechanism that is convenient for material feeding is used, the working process is as follows:

At the same time, the hydraulic cylinder 401 is started again to push the suction cup a405, so that the glass adsorbed by it is placed on the upper surface of the suction cup b904, and the adsorption state between the suction cup a405 and the glass is released. The vacuum pump b901 is started to extract the air between the suction cup b904 and the lower surface of the glass, so that the suction cup b904 is vacuum-adsorbed on the lower surface of the glass. At the same time, the hydraulic push rod 10 is started to push The edge grinding mechanisms 11 on the left and right sides are moved close to the middle glass until the grinding file 1105 in the edge grinding mechanism 11 is attached to the edge of the glass. At this time, the servo motor 1103 can be started to drive the rotating screw 1102 to rotate, and the grinding file 1105 screwed to the outer wall of the rotating screw 1102 will start forward and backward along the inner wall of the slide rail 1101, so as to evenly grind the entire side of the glass and perform a grinding operation on it. During this period, the stepper motor 7 plugged into the bottom of the workbench 6 can drive the limiting mechanism 9 to rotate and adjust the side. When all the sides of the whole piece of glass have been polished, the operator can start the telescopic rod 8 to shorten its driving end downward and drive the entire limiting mechanism 9 to move downward until the fixed plate 903 in the limiting mechanism 9 is flush with the second conveyor belt 1304, and then start the parallel push rod 12 to push forward, and at the same time release the adsorption state between the suction cup b904 and the glass, thereby pushing the glass to the top of the second conveyor belt 1304 to complete the unloading operation.
