[0027] Reference Figure 1-Figure 3 According to an embodiment of a glass edge grinding device with horizontal push positioning of the utility model, it includes a processing table 11, a mounting groove 12 is provided in the upper side surface of the processing table 11, and a mounting plate 13 is provided in the mounting groove 12, a turntable 14 is rotatably connected at the axis of the mounting plate 13, and a No. 1 motor 17 for driving the turntable 14 to rotate is provided on the lower side surface of the mounting groove 12, specifically, a No. 1 output shaft extending from the No. 1 motor 17 is connected to the turntable 14 through a No. 1 gear set, so that the No. 1 motor 17 can drive the turntable 14 to rotate when it is powered on, and a bearing platform 15 for bearing glass is fixedly provided at the upper end of the turntable 14, and a circular glass can be placed on the bearing platform 15, a vacuum groove 16 is provided in the upper side surface of the bearing platform 15, and a negative pressure mechanism 101 for vacuuming the empty groove 16 is provided in the mounting groove 12, when the negative pressure mechanism 101 takes effect, the glass can be adsorbed by the negative pressure and fixed on the bearing platform 15, so as to facilitate the subsequent edge grinding work.

[0028] In order to make the disc-shaped glass coaxial with the supporting platform 15 before the negative pressure mechanism 101 takes effect, an annular groove 18 is provided in the processing table 11, and the annular groove 18 is coaxial with the turntable 14, and three slide grooves are provided in the upper side of the annular groove 18, and the three slide grooves are all oriented toward the axis of the turntable 14, and a rotating disk 19 is rotatably connected in the annular groove 18, and an arc-shaped motion groove is opened on the rotating disk 19, and a movable plate 20 having the same number as the slide grooves and extending to the upper side of the processing table 11 through the slide grooves is threadedly connected on the rotating disk 19, and a push plate 21 is installed in the movable plate 20, and the push plate 21 is installed in the movable plate 20. A No. 2 motor 22 for driving the rotating disk 19 to rotate is provided in the mounting groove 12. Specifically, a No. 2 output shaft extending from the No. 2 motor 22 extends into the annular groove 18 and is connected to the rotating disk 19 through a No. 2 gear set. When the No. 2 motor 22 is energized, it drives the rotating disk 19 to rotate, thereby causing the movable plate 20 to approach or move away from the supporting platform 15, which is similar to the movement principle of the claws in a three-jaw chuck. When the movable plate 20 approaches the supporting platform 15, the push plate 21 pushes the glass on the supporting platform 15 and makes it coaxial with the supporting platform 15.

[0029] Since the size of the rotating disk 19 will limit the stroke of the movable plate 20, in order to enable the push plate 21 to position and center glass of a larger size range, the push plate 21 can be adjusted relative to the movable plate 20. A mounting groove is provided in the movable plate 20, and the push plate 21 is installed in the mounting groove. A plurality of equidistantly arranged sockets are provided in the push plate 21, and a pin 27 inserted into the socket is provided in the movable plate 20. The staff can pull out the pin 27 and then adjust the position of the push plate 21 relative to the movable plate 20 to avoid the movable plate 20 moving to the innermost side while one or more push plates 21 are still not in contact with the glass on the supporting platform 15.

[0030] In the second embodiment of the glass edge grinding device with horizontal push positioning, when pushing thinner glass, in order to prevent the glass from being damaged by excessive friction during the process of the push plate 21 pushing the glass on the supporting platform 15, a carrying ring 23 is installed in the mounting groove 12, and the carrying ring 23 is located on the outside of the supporting platform 15 and is coaxial with the supporting platform 15. A plurality of mounting grooves are provided in the upper side surface of the carrying ring 23, and a ball 24 capable of rolling freely is provided in each of the mounting grooves. In addition, the carrying ring 23 can move up and down, and at least one lifting shaft 25 is rotatably connected in the mounting plate 13, and the lifting shaft 25 is threadedly connected to the carrying ring 23, and the lifting shafts 25 are connected by synchronous belts, and a No. 3 motor 26 is provided on the lower side surface of the mounting groove 12 for driving one of the lifting shafts 25 to rotate, thereby adjusting the upper and lower positions of the carrying ring 23.

[0031] The negative pressure mechanism 101 includes a vacuum pump 28 disposed on the lower side of the mounting groove 12 . A negative pressure hole penetrating downward through the turntable 14 is disposed in the lower side of the empty groove 16 , and the negative pressure hole is connected to the vacuum pump 28 via a rotating air joint.

[0032] Specific glass positioning and clamping process: First, the supporting ring 23 is at the uppermost side, and the ball 24 is higher than the upper side of the supporting platform 15. At this time, the staff places the disc-shaped glass on the ball 24. At this time, the supporting platform 15 is not in contact with the glass and is located on the lower side of the glass. Since the ball 24 can rotate freely, the glass can move with less friction. At this time, the rotating disk 19 rotates and the push plate 21 moves inward. At this time, the glass can move in the center and the ball 24 rolls. A pressure sensor is installed at the end of the push plate 21. When the three pressure sensors sense similar pressures It shows that the three push plates 21 are in contact with the glass and the glass is centered. Then the push plates 21 retreat and are no longer in contact with the glass. Then the No. 3 motor 26 drives the lifting shaft 25 to rotate and causes the supporting ring 23 to sink. At this time, the glass on the supporting ring 23 will move downward until it abuts against the upper side of the supporting platform 15. Then the vacuum pump 28 is energized to generate negative pressure in the empty groove 16. A sealing ring is also provided on the upper side of the supporting platform 15 around the outside of the empty groove 16 to enable the glass to be fixed on the supporting platform 15. At this time, the glass is completely locked in the center.

[0033] Since there is a certain friction between the ball 24 and the mounting groove, and there is a certain friction between the glass and the ball 24, during the sinking process of the supporting ring 23, the glass will not move except up and down.

[0034] In addition, the glass edge grinding equipment with horizontal push positioning also includes a grinding mechanism for grinding the glass located on the supporting platform 15, and the grinding mechanism includes a slide plate 29 arranged on the processing table 11, and the slide plate 29 is equipped with a polishing wheel 30, and the slide plate 29 is equipped with a No. 4 motor 31 for driving the polishing wheel 30 to rotate, and the upper side surface of the processing table 11 is provided with a No. 5 motor 32, and the motor shaft extending from the motor 32 is equipped with a threaded shaft 33 threadedly connected to the slide plate 29.

[0035] Specific grinding and polishing process: After the glass is positioned, the No. 1 motor 17, the No. 4 motor 31 and the motor 32 are energized. When the No. 1 motor 17 is energized, it will drive the glass to rotate through the turntable 14 and the supporting platform 15. When the No. 4 motor 31 is energized, it will drive the polishing wheel 30 to rotate. When the motor 32 is energized, it will drive the slide plate 29 so that the rotating polishing wheel 30 can stick to the edge of the glass on the supporting platform 15 and polish the glass.

[0036] In addition, the polishing wheel 30 can be a concave polishing wheel so that the edge of the glass that has been polished can be directly rounded.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
