Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a grinding device for a glass laser edge cutting and grinding equipment. Background Technology

[0002] In the manufacturing process of glass products, multiple steps such as cutting, grinding, and polishing are typically required to achieve ideal dimensional accuracy and edge quality. In recent years, laser cutting technology has been widely used in the cutting and processing of glass sheets due to its advantages such as high precision, non-contact operation, and smooth cuts. Laser cutting is mainly used to segment the contours of glass sheets, enabling efficient cutting of complex curves or irregular boundaries. However, due to the brittle nature of glass, defects such as microcracks, burrs, or heat-affected zones often exist at the edges after laser cutting. Therefore, further grinding is necessary to refine the glass cut edges, remove burrs, improve surface smoothness, and enhance the strength of the finished product.

[0003] Existing glass grinding equipment generally uses grinding blades or grinding heads to physically contact and refine the glass edges. Due to the diverse shapes of glass edges, the grinding process requires not only controlling the depth of cut but also adjusting the angle according to the edge's tilt or shape. For example, in processing the notch for glass door hinge installation, the notch is first formed and cut using laser technology, and then the laser-processed edge is ground. However, in existing technologies, grinding blades (grinding heads) can typically only move horizontally in a single direction, lacking flexibility in angle adjustment; even when angle adjustment is available, the process is cumbersome, resulting in a narrow applicability and low operational efficiency. Furthermore, to ensure the quality of the glass edges during grinding, the depth of cut must be precisely controlled. If the depth of cut is improperly controlled or excessive, a large impact force is generated upon contact between the grinding blade and the glass edge, easily causing the glass edge to crack or break, or even leading to equipment vibration or damage, compromising safety and processing stability. Utility Model Content

[0004] This utility model proposes a grinding device for glass laser edge cutting and grinding equipment to solve the problems mentioned in the background art, such as the grinding blade being able to move horizontally in only one direction during the existing glass grinding process, which cannot flexibly adjust the angle, resulting in a narrow range of applications, low operating efficiency, and difficulty in accurately controlling the feed amount during the grinding process, which can easily cause glass edge cracking or damage and poor safety.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As shown in the figure, a grinding device for a glass laser edge cutting and grinding equipment includes:

[0031] The rotating seat 11 is capable of moving along the horizontal X-axis and Y-axis and can rotate, specifically rotating along a designated rotation center line parallel to the Z-axis.

[0032] The feed plate 12 is movably mounted above the rotary seat 11 and is configured to perform feed and retraction operations during glass grinding.

[0033] The grinding assembly is mounted on the feed plate 12 and can move with the feed plate 12. It includes a rotatable grinding blade 17, which is used to grind the edge of the glass.

[0034] A protective component is disposed between the grinding component and the feed plate 12, and is configured to prevent the grinding tool 17 from directly impacting the glass and causing glass damage when the grinding tool 17 is grinding.

[0035] The aforementioned rotating base 11 can move in the horizontal X-axis and Y-axis directions, that is, it can move the grinding blade 17 to any position on the glass plate that needs to be ground. Since the grinding blade 17 moves in a straight line when it is fed in, in order to facilitate the grinding of different edges of the glass, the rotating base 11 is equipped with a rotation adjustment function, so that the grinding assembly can be rotated at an angle to facilitate the grinding of the edges of the glass in different directions.

[0036] Specifically, a transverse moving plate 3 capable of moving along the X-axis is provided below the rotating base 11. A servo motor 6 is installed at the lower end of the transverse moving plate 3 near the front. The output shaft of the servo motor 6 is connected to a harmonic reducer 5 mounted on the transverse moving plate 3. The rotating base 11 is installed above the harmonic reducer 5. Below the transverse moving plate 3, a longitudinal moving plate 1 capable of moving along the Y-axis is provided. A transverse moving motor 7 is installed above the longitudinal moving plate 1. The output shaft of the transverse moving motor 7 is connected to a lead screw 8. A lead screw nut 9 is connected to the lead screw 8. The lead screw nut 9 is connected to the transverse moving plate 3 and is configured to move the transverse moving plate 3 above the longitudinal moving plate 1 in the X-axis direction. In this example, the longitudinal moving plate 1 is assembled on a laser cutting and grinding equipment using a longitudinal moving motor 2, a longitudinal moving reducer 4, and a gear and rack structure. This allows the longitudinal moving plate 1 to move along the Y-axis. In this example, the Y-axis movement of the longitudinal moving plate 1 and the X-axis movement of the transverse moving plate 3 are both guided linearly by a guide rail slider structure. The specific structure and principle are conventional in existing technology and will not be elaborated further here. Thus, under the combined action of the longitudinal moving plate 1 and the transverse moving plate 3, the rotating seat 11 can move freely in the horizontal direction, thereby allowing the front-end grinding component to move to any position on the glass plate.

[0037] Specifically, a grinding cylinder 10 is installed at one upper end of the rotating seat 11. The end of the telescopic rod of the grinding cylinder 10 is connected to the feed plate 12. A guide rail slider assembly is provided between the feed plate 12 and the rotating seat 11. The feed plate 12 is configured to move horizontally under the drive of the grinding cylinder 10. That is, during the grinding process, the grinding blade 17 is moved forward by the grinding cylinder 10, and the side wall of the grinding blade 17 contacts the edge of the glass to achieve a fast grinding effect.

[0038] Specifically, the protective assembly includes a first protective assembly 13, which includes a first frame 1303 and a first slide block 1301 mounted on the surface of the feed plate 12. A first linear shaft 1302 is passed through and slidably connected to the first slide block 1301. The two ends of the first linear shaft 1302 pass through the two side walls of the first frame 1303 and slide in cooperation with the first frame 1303. A first spring 1304 is sleeved on both ends of the first linear shaft 1302. One end of the first spring 1304 abuts against the side wall of the first frame 1303, and the other end abuts against the end of the adjacent first slide block 1301. The axis of the first linear shaft 1302 is perpendicular to the movement trajectory of the feed plate 12.

[0039] Specifically, the protective assembly further includes a second protective assembly 14, which includes a second frame 1403 fixed on the grinding assembly and a second slide block 1401 fixed above the first frame 1303. A second linear shaft 1402 is slidably installed in the second slide block 1401. Both ends of the second linear shaft 1402 pass through the side walls of the second frame 1403 and slide in cooperation with the second frame 1403. A second spring 1404 is sleeved on one end of the second linear shaft 1402 near the grinding assembly. One end of the second spring 1404 abuts against the side wall of the second frame 1403, and the other end abuts against the end of the adjacent second slide block 1401. The axis of the second linear shaft 1402 is parallel to the movement trajectory of the feed plate 12.

[0040] The first protective component 13 and the second protective component 14 are set up to buffer and protect the material when the tool is fed in the X-axis direction and the Y-axis direction, respectively, by compressing the second spring 1404 and the first spring 1304. Specifically, the compression deformation of the springs is used to absorb the instantaneous impact force, avoid the grinding tool 17 from forming a rigid collision with the glass plate, thereby preventing the glass edge from cracking or breaking, improving the safety and effect of grinding.

[0041] Specifically, the grinding assembly includes a grinding stand 15, which is connected to the protective assembly. The grinding stand 15 is specifically connected to the end of the second frame 1403. An electric spindle 16 is installed on the outer end of the grinding stand 15, and a grinding tool 17 is connected to the output end of the electric spindle 16.

[0042] Specifically, the front end of the rotating seat 11 is connected to a pressure block 18. There are two pressure blocks 18, which are located on both sides of the grinding blade 17. In actual operation, the pressure blocks 18 can be gradually brought closer to the edge of the glass to position and press the glass. Then, under the action of the grinding cylinder 10, the grinding blade 17 moves forward to perform grinding. The pressure blocks 18 can prevent the glass from shaking and wobbling when it comes into contact with the grinding blade 17 in the grinding area.

[0043] The grinding device of this glass laser cutting and grinding equipment is specifically installed on a laser cutting and grinding machine with both laser cutting and grinding functions. After the glass is laser cut, the edges of the cut glass need to be ground. At this time, the grinding device is activated. In specific operation, the longitudinal moving plate 1 and the transverse moving plate 3 move the grinding component in front to the area that needs to be ground. According to actual needs, the pressure block 18 presses against the edge of the glass to achieve the glass positioning effect. At this time, the grinding cylinder 10 is activated, driving the feed plate 12 and its protective components and grinding components to move. The grinding blade 17 of the grinding component contacts the edge of the glass during movement, thereby realizing the grinding process. During this process, the spring structure set in the first protective component 13 and the second protective component 14 can provide a safe buffering effect for the grinding blade 17 in the horizontal direction, avoiding the problem of hard impact between the grinding blade 17 and the glass during the feed and grinding process, which helps to prevent damage to the glass. When the edge to be ground is in other directions, the rotating seat 11 can be moved to a suitable angle by the action of the servo motor 6 and the harmonic reducer 5. Then, the grinding cylinder 10 is used to drive the grinding cutter 17 to move, and the glass edge in different directions is ground.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
