Description

Technical Field

[0001] This utility model relates to the field of automatic glass processing technology, and more specifically, to a glass grinding device and a glass cutting and grinding device. Background Technology

[0002] The windshields, rear windshields, and side windows used in automobiles are automatically processed from raw glass using fully automated multi-functional glass processing equipment. The glass processing steps of this equipment mainly include sequential processes such as feeding, positioning, handling, cutting, edge bending, edge grinding, and drilling.

[0003] The edging process involves using a high-speed rotating grinding wheel to grind the edges of the glass. The structure of the corresponding grinding device can be referenced from utility model patents CN214723001U and CN205968523U. Its basic structure involves a motor driving the grinding wheel to rotate at high speed. The grinding device is equipped with a rotary mechanism, which rotates the entire device (at a relatively slow speed) to adapt to the entire grinding path of the glass edge. This rotary mechanism is mounted on the XY linear module of the automatic glass processing equipment, allowing the module to move the rotary mechanism to any position on the horizontal plane. The rotary mechanism specifically includes a motor and two meshing gears. The motor's operation, transmitted through the two gears, causes the entire grinding device to rotate. Because the entire grinding device is relatively heavy and suspended along the Z-axis, prolonged operation can lead to wear on the two gears, resulting in unstable rotation, slight vibrations, and ultimately affecting the edging quality of the glass.

[0004] The cutting process is completed by a cutting device. The structure of the cutting device can be referenced in the utility model patent with authorization announcement number CN205974256U and the invention patent application with application publication number CN106082623A.

After long-term operation, the two gears wear down, resulting in unstable rotation of the entire grinding device and generating slight vibrations, which ultimately affects the quality of glass edge grinding. The application provides a glass grinding device and a glass cutting grinding device that ensures stable rotation of the entire grinding device.

Those skilled in the art can make modifications or variations based on the principles, concepts, and spirit of this application, and the resulting technical solutions should all be covered within the scope of protection of this application.

[0027] like Figure 1 As shown, the glass grinding device 100 and the glass cutting device 200 are respectively mounted on the slide plate 1. The slide plate 1 is mounted on the XY linear module of the automatic glass processing equipment. The movement of the XY linear module can move the glass grinding device 100 to any position on the horizontal plane, that is, move the grinding wheel of the glass grinding device 100 to any position on the horizontal plane, thereby adapting to the glass edge. Similarly, the movement of the XY linear module can move the glass cutting device 200 to any position on the horizontal plane.

[0028] like Figure 1-4As shown, the glass grinding device 100 includes a servo motor 101, a reducer 102, a support frame 103, a roller assembly 104, a gear ring 105, a gear ring connecting sleeve 106, a hollow spindle 107, a bearing support seat 108, an upper bearing 109, a lower bearing 110, a grinding head assembly bracket 111, and a grinding head assembly 112.

The roller assembly 104 is connected to the output shaft of the reducer 102. The support base 108 is fixedly connected to the support frame 103. The upper part of the hollow spindle 107 is rotatably connected to the bearing support base 108 via the upper bearing 109, and the lower part of the hollow spindle 107 is rotatably connected to the bearing support base 108 via the lower bearing 110. The gear ring connecting sleeve 106 is fixedly connected to the upper end of the hollow spindle 107, and the gear ring 105 is fixedly connected to the gear ring connecting sleeve 106 via screws. The roller assembly 104 is provided with multiple rolling pins distributed along the circumferential direction. The rolling pins roll and mesh with the tooth surface of the gear ring 105 to achieve backlash-free meshing transmission. The gear ring 105 is located in the horizontal plane, and the hollow spindle 107 is located in the Z-axis direction. The grinding head assembly bracket 111 is fixedly connected to the lower end of the hollow spindle 107. The grinding head assembly 112 is existing technology. The grinding head assembly 112 typically includes a grinding wheel seat, a grinding wheel, a grinding wheel rotation drive motor, a motor bracket, etc. The grinding wheel is connected to the grinding wheel seat, the grinding wheel seat is connected to the output shaft of the grinding wheel rotation drive motor, the grinding wheel rotation drive motor is mounted on the motor bracket, and the motor bracket is fixedly mounted on the grinding head assembly bracket 111.

[0029] The servo motor 101 is started, causing the roller assembly 104 to rotate. The roller assembly 104 drives the gear ring 105 to rotate, which in turn drives the hollow spindle 107 to rotate, thereby driving the grinding head assembly support 111 and the grinding head assembly 112 to rotate, thus realizing the rotary motion of the grinding head assembly 112. Due to the use of roller assembly 104 and gear ring 105 for transmission, the grinding head assembly 112 achieves backlash-free and stable rotation, ensuring the accuracy and stability of glass edge grinding and adapting to the entire grinding path of the glass edge. Even during long-term operation, the glass grinding device 100 can still maintain the stability of the entire grinding device's rotation, avoiding minor vibrations and ensuring the quality of glass edge grinding.

The Z-axis rotating shaft 206 is rotatably connected to the connecting frame 207 via bearings. The driven synchronous pulley 205 is connected to the upper end of the Z-axis rotating shaft 206. The synchronous belt 204 connects the driving synchronous pulley 203 and the driven synchronous pulley 205. The cutting assembly 208 is connected to the lower end of the Z-axis rotating shaft 206.

[0031] The connecting bracket 207 is fixedly installed on the slide plate 1.

[0032] The servo motor 201 and synchronous belt drive mechanism can stably rotate the cutting component 208, ensuring the accuracy of the rotation of the cutting component 208 and adapting to the entire cutting path of the edge of the glass to be cut.

[0033] The glass cutting device 200 and the glass grinding device 100 are mounted on the same slide plate 1. When the slide plate 1 moves in the XY plane, the glass cutting device 200 performs edge grinding on the corresponding glass while simultaneously cutting it. This helps ensure the synchronization of the movements of the glass cutting device 200 and the glass grinding device 100, and guarantees the consistency of the cutting and grinding paths. This improves the quality of glass processing and reduces the scrap rate.
