[0022] Referring to Figures 1-5 , a feeding device for grinding crystal glass, including a base 1. An installation hole is provided at the upper end of the base 1 to facilitate the user to fix the base 1 on the ground with bolts. Above the base 1, there is a horizontally arranged support plate 4 for supporting the vacuum pump 10. At the upper end of the support plate 4 and near the right edge, a support pillar 2 is inserted for supporting the support plate 4. The support pillar 2 and the support plate 4 are rotatably connected. The lower end of the support pillar 2 penetrates through the support plate 4 and is fixedly connected to the upper end of the base 1. Two support rings are fixedly sleeved on the support pillar 2 for supporting the support plate 4. The two support rings are respectively rotatably connected to the upper and lower sides of the support plate 4. Both sides of the support pillar 2 are fixedly connected with support blocks for providing side support for the support pillar 2. The lower ends of the support blocks are fixedly connected to the upper end of the base 1;

[0023] In this embodiment, a placement groove is provided on the outer side wall of the support pillar 2. A servo motor 13 is fixedly connected to the inner bottom of the placement groove for driving the gear 14 to rotate. The end of the output shaft of the servo motor 13 is fixedly connected with a gear 14 for driving the rack to rotate. An annular connection groove is provided on the inner side wall of the support plate 4. A rack meshing with the gear 14 is fixedly connected to the inner side wall of the connection groove for driving the support plate 4 to rotate. The rack is annularly arranged. A part of the gear 14 penetrates through the placement groove and extends into the connection groove;

[0024] In this embodiment, an electric push rod 5 is fixedly inserted at the lower end of the support plate 4 for driving the connection plate 7 to lift and lower. The upper end of the electric push rod 5 penetrates through the support plate 4. A connection plate 7 is provided at the lower end of the support plate 4 for cooperating with negative pressure to adsorb crystal glass. The lower end of the electric push rod 5 is fixedly connected to the upper end of the support plate 4. Two guide rods 6 are fixedly connected to the upper end of the connection plate 7 for guiding the lifting and lowering of the connection plate 7. The upper ends of the guide rods 6 slidably penetrate through the support plate 4. A rubber ring 8 is fixedly connected to the lower end of the connection plate 7 for preventing the crystal glass from being damaged;

[0025] In this embodiment, a groove is provided at the lower end of the connection plate 7. A pressure sensor is fixedly connected to the inner top of the groove for detecting the negative pressure value in the groove. The model of the pressure sensor is MPX4115A. An electromagnetic valve 9 communicating with the groove is fixedly connected to the outer side wall of the connection plate 7 for enabling the inside of the groove to communicate with the outside and restoring the air pressure to the normal value. The model of the electromagnetic valve 9 is 2W-20. An installation groove is provided on the outer side wall of the connection plate 7. A vacuum pump 10 is fixedly connected to the inner top of the installation groove for cooperating with the suction pipe 12 to extract the gas in the groove. The model of the vacuum pump 10 is KVP15-KJ-1. The suction end of the vacuum pump 10 is fixedly communicated with a suction pipe 12 for gas circulation. One end of the suction pipe 12 penetrates through the connection plate 7 and extends into the groove. A check valve 11 is fixedly connected in the suction pipe 12 for preventing gas backflow and leakage.

[0026] In this embodiment, a controller 3 is fixedly connected to the outer side wall of the support column 2 for controlling the start and stop of the vacuum pump 10 and the electromagnetic valve 9. The model of the controller 3 is 80S51. The input end of the controller 3 is electrically connected to the output end of the pressure sensor. The output end of the controller 3 is respectively electrically connected to the input ends of the vacuum pump 10 and the electromagnetic valve 9.

[0027] In this embodiment, first, the crystal glass to be processed is stacked beside the grinding machine, and then the device proposed in this application is installed between the crystal glass and the grinding machine. The servo motor 13 is started to drive the gear 14 to rotate. The rack meshing with the gear 14 is driven to rotate by the gear 14. The support plate 4 is driven to rotate by the rack. The connection plate 7 is driven to rotate above the stacked crystal glass to be processed by the rotation of the support plate 4. At this time, the electric push rod 5 is started to drive the connection plate 7 to descend, so that the lower end of the connection plate 7 is attached to the crystal glass. The rubber ring 8 is used to improve the sealing performance between the crystal glass and the connection plate 7 and prevent the crystal glass from being damaged. At this time, the vacuum pump 10 is started to cooperate with the suction pipe 12 to perform a pumping operation on the groove, so that a negative pressure is generated in the groove. (When the vacuum pump 10 is started, the check valve 11 will open under the influence of air pressure. When the vacuum pump 10 is turned off, the check valve 11 automatically closes to prevent gas leakage). The crystal glass is adsorbed by the negative pressure. Then, the crystal glass is driven to rise by the electric push rod 5 and the connection plate 7. The connection plate 4 is rotated above the workbench of the grinding machine by the servo motor 13 and the gear 14. Subsequently, the crystal glass is lowered onto the workbench of the grinding machine by the electric push rod 5. Finally, the electromagnetic valve 9 is opened to enable the gas in the groove to circulate and the air pressure to return to normal. At this time, the crystal glass cannot be adsorbed, and the crystal glass can be separated from the connection plate 7, realizing the automatic placement of the crystal glass from the stacking place onto the workbench of the grinding machine. At the same time, the negative pressure value in the groove is detected by the pressure sensor. When the negative pressure reaches the preset value, a signal is sent to the controller 3, and the vacuum pump 10 is turned off by the controller 3, thus avoiding potential safety hazards caused by excessive negative pressure values.

[0028] As described above, the servo motor, electric push rod, vacuum pump, solenoid valve, controller and air pressure sensor are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This application only utilizes their functions without improving their internal structures. Therefore, no detailed description will be given.

[0029] As described above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
