Description

Technical Field

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

[0002] In the glass processing industry, glass products typically require multiple processes such as blanking, cutting, grinding, cleaning, and polishing before they can be used. Among these, laser cutting technology, with its advantages of non-contact processing, smooth cuts, high precision, and resistance to edge chipping, has gradually replaced traditional mechanical scratching and thermal cutting processes, becoming the mainstream method for modern glass cutting. After cutting, grinding is necessary to remove burrs, stress concentration areas, or micro-cracks from the glass edges, thereby improving the quality and safety performance of the finished glass products. The grinding process is usually achieved using grinding heads, grinding wheels, or diamond grinding tools. By micro-grinding the edges of the glass sheet, a smooth, neat edge and a safe chamfer are achieved.

[0003] However, existing glass processing equipment still has many shortcomings. First, glass cutting and grinding equipment are usually two separate machines. After cutting, the glass sheet needs to be removed from the cutting machine manually or mechanically and then transferred to the grinding machine for grinding. This separate processing flow not only increases the equipment footprint and manual handling costs, but also leads to a higher risk of glass breakage during handling, low processing efficiency, and insufficient overall automation.

[0004] Secondly, existing glass grinding equipment has a simple structure. The grinding head can generally only move horizontally in one direction and cannot achieve 90° angle adjustment. Alternatively, the angle adjustment structure is complex and the precision is not high. When grinding different edges of the glass plate, it is often necessary to manually rotate the glass plate 90° before performing grinding operations in another direction. This method is cumbersome, has large positioning errors, and is not conducive to achieving automated continuous processing.

[0005] Furthermore, insufficient precision control during grinding is another defect of the current equipment. During the grinding process, due to the high brittleness of the glass material, the grinding head is prone to generating a large instantaneous impact force when it comes into contact with the glass, causing the glass edge to crack or develop cracks, which seriously affects the appearance and pass rate of the products. Utility Model Content

[0029] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0030] This invention integrates a laser processing unit and a grinding unit on the same machine bed, and centrally controls them through a PLC system built into the electrical control box. This allows the glass plate to complete both laser cutting and grinding processes within the same equipment, avoiding the need for cutting and grinding to be performed on two separate machines and for manual handling of the glass, as required in the prior art. This significantly reduces process connection time and handling costs, improves processing efficiency and automation, and also reduces the risk of glass breakage during transport.

[0031] The feed assembly and grinding assembly in this utility model grinding unit can rotate at an angle, that is, they can both move along the X-axis and Y-axis directions. This allows the grinding blade to grind the right-angled edge of the glass in different directions without rotating the glass plate, which greatly simplifies the operation process, improves grinding efficiency and automation, and avoids positioning errors and safety hazards caused by manually rotating the glass.

[0032] This invention features a first protective component and a second protective component in the feed direction. When the grinding component feeds along the X-axis or Y-axis, it achieves elastic buffering by compressing the first and second springs. The compression deformation of the springs absorbs the instantaneous impact force, effectively preventing the grinding tool from forming a rigid collision with the glass plate, thereby preventing the glass edge from cracking or breaking and significantly improving the safety and yield of the grinding process.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0057] As shown in the figure, a laser cutting and grinding equipment for glass processing includes a bed 1, a conveying and positioning unit 2, a laser processing unit 3, a grinding unit 4, and an electrical control box 5. The electrical control box 5 has a built-in PLC control system for realizing the automated control of the entire equipment.

[0058] Among them, the bed 1 serves as the bottom support and installation foundation of the entire equipment, supporting the installation and operation of various functional units. It can be made in various forms such as castings, welded steel structures or steel splicing structures according to processing requirements.

[0059] The conveying and positioning unit 2 is mounted on the bed 1 and configured to convey the glass plate along the Y-axis, and after being conveyed to a designated position, to move the glass plate along the Z-axis to form a positioning, and to export the glass plate after processing. In this example, the X-axis direction is the width direction of the bed 1, the Y-axis direction is the length direction of the bed 1, and the Z-axis direction is the vertical direction.

[0060] The laser processing unit 3 is located above the bed 1 and includes at least one set of laser cutting components 32 that can move along the X-axis and Y-axis directions. It is configured to perform laser cutting on the glass plate. In this example, the length of the entire bed 1 exceeds 4m, so there are two sets of laser cutting components. It is understood that in other embodiments, one or more sets of laser cutting components 32 can be designed according to actual needs. Since the laser cutting components 32 can move along the X-axis and Y-axis directions, and the glass plate is placed in the middle of the bed 1, the laser cutting components 32 can radiate to any position of the glass plate to achieve laser cutting.

[0061] The grinding unit 4 is disposed above the bed 1 and includes at least one set of feed assembly and grinding assembly 42 capable of moving along the X and Y axes and rotating horizontally. In this example, two sets of feed assembly and two sets of grinding assembly 42 are provided. In other embodiments, one or more sets can be designed according to the overall length of the bed 1. The grinding assembly 42 is mounted on the feed assembly and includes a rotatable grinding cutter 423. It is configured such that when the grinding cutter 423 rotates, the feed assembly drives the grinding cutter 423 to move horizontally, thereby grinding the glass.

[0062] The feed assembly includes a horizontally movable feed plate 47. A protective component is provided between the feed plate 47 and the grinding assembly 42. The protective component is configured to prevent the grinding tool 423 from excessively hard impacting the glass plate, thereby causing damage to the glass plate.

[0063] Specifically, the conveying and positioning unit 2 includes an end guide component 21 and a middle conveying and positioning component 22.

[0064] The end guide assembly 21 is rotatably mounted at both ends of the bed 1 and includes several evenly distributed guide rollers 212. It is configured such that the glass plate moves to the upper middle position of the bed 1 under the action of the end guide assembly 21, and after the glass plate is separated from the end guide assembly 21, the end guide assembly 21 flips over to prevent interference between the laser processing unit 3 and the grinding unit 4 during operation.

[0065] More specifically, the end guide assembly 21 further includes a guide frame 213, with guide connecting frames 211 fixed on both sides of the guide frame 213. The guide connecting frames 211 are hinged to the bed 1. Bearing seats are installed at the ends of the bed 1 on both sides. A horizontally arranged shaft is installed on the guide connecting frame 211, and the shaft is connected to the bearing seats through bearings, thereby realizing the rotatable connection of the guide connecting frame 211 relative to the bed 1. It is understood that in other embodiments, the rotatable connection between the guide connecting frame 211 and the bed 1 can also adopt other methods, which are not limited here. A guide cylinder 215 is installed between the bed 1 and the guide connecting frame 211. The fixed end of the guide cylinder 215 is hinged to the bed 1, and the end of the telescopic rod of the guide cylinder 215 is hinged to the guide frame 213. A plurality of rotating shafts 214 are evenly installed above the guide frame 213, and the guide rollers 212 are installed on the rotating shafts 214.

[0066] The purpose of the end guide assembly 21 is to facilitate the placement of the glass plate on the guide roller 212, pushing the glass plate to be fed onto the conveyor 223 of the middle conveying and positioning assembly 22. After processing, the glass plate is then guided by the conveyor 223 to the rear end guide assembly 21, thus achieving the guiding and conveying of the glass plate. The end guide assembly 21 can rotate because the laser cutting assembly 32 and the grinding assembly 42 need to move along the X-axis during operation. To achieve this movement, a linear module needs to be installed on the bed 1 along the X-axis. The linear module is located below the end guide assembly 21. When the laser cutting assembly 32 or the grinding assembly 42 moves along the X-axis, its movement path will interfere with the position of the end guide assembly 21. Therefore, during glass processing, by rotating the end guide assembly 21 to an upright position, the movement space of the laser cutting assembly 32 and the grinding assembly 42 can be avoided, thus preventing interference and ensuring smooth processing.

[0067] The central conveying and positioning assembly 22 includes a support frame 221 fixedly or slidably connected to the bed 1. The support frame 221 is equipped with a liftable conveyor 223, and a lifting cylinder 222 is mounted on the support frame 221. The upper end of the lifting cylinder 222 is connected to the conveyor 223 to realize the vertical movement of the conveyor 223. It is understood that in other embodiments, a motor combined with a ball screw, a hydraulic cylinder, or other mechanisms with linear drive functions can also be used. In this example, two sets of conveyors 223 are provided. The conveyors 223 are belt conveyors 223. After the glass plate is placed on the surface of the conveyor 223, it can move along the Y-axis. The support frame 221 has an overall L-shaped structure. A guide rail slider mechanism is provided between the support frame 221 and the bed 1 at its bottom. This mechanism allows the support frame 221 to move along the X-axis, facilitating the adjustment of the distance between the two conveyors 223 for conveying glass plates of different widths. Once the position of the conveyor 223 is determined, the guide rail slider mechanism is locked to keep the support frame 221 fixed. It is understood that in other embodiments, the support frame 221 can be directly fixed to the bed 1, and in other embodiments, the number of conveyors 223 can be one, three, or more.

[0068] A support and positioning component is installed above the support frame 221. The support and positioning component is configured to position the glass plate at the end and then support the glass plate. A fine-tuning component 224 is provided between the support and positioning component and the support frame 221, which is configured to adjust the vertical position of the support and positioning component.

[0069] Specifically, the support and positioning assembly includes a support frame 227, which extends along the Y-axis. The support frame 227 is equipped with several spaced-apart support heads 226. Two sets of blocking mechanisms capable of moving along the Y-axis are located in the middle of the bed 1. Each blocking mechanism includes two blocking cylinders 225 arranged along the X-axis. The blocking cylinders 225 are used to limit and position the front and rear ends of the glass. Specifically, the two blocking cylinders 225 in the same set are mounted on a moving plate, which can reciprocate along the Y-axis. The movement can be achieved using a motor in conjunction with a ball screw and nut. To achieve precise positioning and stability when clamping the glass, the outer wall of the telescopic rod of the blocking cylinder 225 near the glass is planar. Multiple positioning wheels 228 spaced-apart along the Y-axis are installed on the outer side of the support frame 227, with the axial direction of the positioning wheels 228 perpendicular to the horizontal plane. When the glass is being transported and positioned, the conveyor 223 first transports the glass along the Y-axis. At this time, the telescopic rods of the two front blocking cylinders 225 are at their upper limit positions, with their upper ends higher than the surface of the conveyor 223, allowing them to contact the front end of the glass plate. Once the glass plate contacts the telescopic rods of the blocking cylinders 225, the glass plate has reached the designated position. At this point, the horizontal X-axis movement of the grinding unit 4 can push the glass plate, causing it to contact the outer wall of the positioning wheel 228 for accurate positioning. Then, the conveyor 223 moves down, allowing the glass to fall onto the support head 226. Subsequently, the two rear blocking cylinders 225 extend and move along the Y-axis, contacting the rear end of the glass. This allows the two sets of blocking cylinders 225 to clamp the glass, enabling the laser cutting and grinding process to be performed while the glass is stationary.

[0070] Specifically, the fine-tuning mechanism includes a fine-tuning fixing plate 2241 fixed to the side of the support frame 221 and a fine-tuning sliding plate 2246 installed on the side of the support bracket 227. The fine-tuning fixing plate 2241 and the fine-tuning sliding plate 2246 are slidably engaged, and their sliding direction is the Z-axis direction. A fine-tuning seat 2247 is installed on the side of the support bracket 227. The fine-tuning seat 2247 has a U-shaped structure. A fine-tuning nut 2242 is fixed to the side of the fine-tuning fixing plate 2241. One end of the fine-tuning nut 2242 extends to the U-shaped fine-tuning seat 2247. Inside 47, a screw 2243 is installed on the fine-tuning seat 2247. The screw 2243 is threadedly engaged with the fine-tuning nut 2242. A fine-tuning handle 2244 is installed at the end of the screw 2243. By rotating the fine-tuning handle 2244, the fine-tuning nut 2242 can be moved relative to the center of the screw 2243, thereby driving the fine-tuning fixing plate 2241 to move vertically relative to the fine-tuning slide plate 2246. The purpose is to adjust the height of the support frame 227 to meet different processing requirements. In this example, the fine-tuning slide plate 2246 and the fine-tuning fixing plate 2241 are slidably engaged using a dovetail joint structure, and an insert 2245 is installed between the fine-tuning slide plate 2246 and the fine-tuning fixing plate 2241. When the fine-tuning slide plate 2246 moves to the designated position, the fine-tuning fixing plate 2241 and the fine-tuning slide plate 2246 can be locked from the side using screws.

[0071] Specifically, a grinding moving beam 41 extending along the Y-axis and movable along the horizontal X-axis is located on one side above the bed 1. In this example, the lower end of the grinding moving beam 41 is connected to the bed 1 via a linear module, meaning the grinding moving beam 41 can move along the X-axis under the action of the linear module. A grinding tray 43 movable along the Y-axis is mounted on the grinding moving beam 41. The movement of the grinding tray 43 is achieved by a motor in conjunction with a gear and rack structure; it can be understood that a linear module method can also be used. A sliding plate 44 movable along the X-axis is mounted on the grinding tray 43. The movement of the sliding plate 44 is achieved by a motor in conjunction with a lead screw and nut. In addition, for guidance, all movable parts in this embodiment are equipped with a guide rail slider mechanism during movement. This guiding structure and linear drive method are conventional designs in the prior art and will not be elaborated further here.

[0072] A rotating seat 45 is rotatably mounted on the sliding plate 44. The feed assembly is mounted above the rotating seat 45. The feed assembly also includes a grinding cylinder 46 mounted above the rotating seat 45. The telescopic rod of the grinding cylinder 46 is connected to the feed plate 47. Specifically, a rotary motor 410 is mounted below the sliding plate 44. The sliding plate 44 and the rotating seat 45 are connected via a harmonic reducer 412. The output shaft of the rotary motor 410 is connected to the middle of the harmonic reducer 412. The rotary motor 410 and the harmonic reducer 412 can drive the rotating seat 45 to rotate, thereby enabling the feed assembly and the grinding assembly 42 above the rotating seat 45 to rotate together for grinding certain right-angled sides of the glass plate. For example, a glass plate has right-angled edges formed along the X-axis and Y-axis. These right-angled edges are cut into shape by the laser cutting assembly 32. At this time, the grinding blade 423 is first moved to the vicinity of the glass plate along the X-axis and Y-axis. During grinding, the grinding cylinder 46 is started, which drives the feed plate 47 and the grinding blade 423 to move together along the X-axis. When the grinding blade 423 rotates, one of the right-angled edges is ground along the X-axis using the outer wall of the grinding blade 423. After the grinding is completed, the rotary motor 410 and the harmonic reducer 412 drive the rotary seat 45 and the feed plate 47 and the grinding assembly 42 above it to rotate 90° together. After adjusting the position, the grinding cylinder 46 is started again, and the other right-angled edge can be ground along the Y-axis.

[0073] Specifically, the protective components include a first protective component 48 and a second protective component 49.

[0074] The first protective component 48 includes a first frame 483 and a first slide block 481 fixed to the surface of the feed plate 47. A first linear shaft 482 is slidably installed in the first slide block 481. The two ends of the first linear shaft 482 pass through the two side walls of the first frame 483 and slide in cooperation with the first frame 483. A first spring 484 is sleeved on both ends of the first linear shaft 482. One end of the first spring 484 abuts against the side wall of the first frame 483, and the other end abuts against the end of the adjacent first slide block 481. In this example, there are two first linear shafts 482 and four first slide blocks 481. Each first linear shaft 482 passes through two first slide blocks 481.

[0075] The second protective assembly 49 includes a second frame 492 fixed to the grinding assembly 42 and a second slide block 491 fixed above the first frame 483. A second linear shaft 494 is slidably mounted in the second slide block 491. Both ends of the second linear shaft 494 pass through the side walls of the second frame 492 and slide in cooperation with the second frame 492. A second spring 493 is sleeved on one end of the second linear shaft 494 near the grinding assembly 42. One end of the second spring 493 abuts against the side wall of the second frame 492, and the other end abuts against the end of the adjacent second slide block 491. In this example, there are two second linear shafts 494 and four second slide blocks 491. Each second linear shaft 494 passes through two first slide blocks 481. The structure of the linear shaft and slide block can adopt the linear bearings in the prior art. In this example, the first frame 483 does not contact the feed plate 47 below, and the second frame 492 does not contact the first frame 483 below.

[0076] The first protective component 48 and the second protective component 49 are set up to buffer and protect the glass when the tool is fed in the X-axis direction and the Y-axis direction, respectively, by compressing the second spring 493 and the first spring 484. Specifically, the compression deformation of the springs is used to absorb the instantaneous impact force, avoid the grinding tool 423 from forming a rigid collision with the glass plate, thereby preventing the glass edge from cracking or breaking, and improving the grinding safety and yield.

[0077] Specifically, the grinding assembly 42 also includes a grinding stand 421, which is connected to the protective assembly. The grinding stand 421 is specifically connected to the second frame 492. An electric spindle 422 is fixed on the surface of the grinding stand 421. The grinding cutter 423 is connected to the electric spindle 422. The electric spindle 422 is mainly used to drive the grinding cutter 423 to rotate.

[0078] Specifically, the rotating base 45 has two pressure blocks 424 connected to its end. These two pressure blocks 424 are positioned on either side of the grinding cutter 423, configured to prevent glass movement during grinding by contacting the glass plate. Furthermore, during glass positioning, the conveyor 223 transports the glass to a designated position, allowing the sides of the two pressure blocks 424 to contact the glass side. As the pressure blocks 424 move along the X-axis, they can contact the positioning wheel 228 on the other side, achieving precise glass positioning. Once precise positioning is complete, during the grinding process, the sides of the two pressure blocks 424 contact the glass side, pressing and clamping the glass to prevent potential glass movement during grinding.

[0079] Specifically, the upper side of the bed 1 has a laser cutting beam 31 extending along the Y-axis and capable of horizontal movement along the X-axis. The laser cutting beam 31 also uses a linear module mounted on the bed 1 to achieve horizontal movement along the X-axis. The laser cutting assembly 32 is mounted on the laser cutting beam 31. The laser cutting assembly 32 includes a lifting plate 321 capable of moving along the Z-axis. A laser emitting head 322 is mounted on the lifting plate 321. More specifically, the laser cutting assembly 32 also includes a horizontal moving frame 323 that moves along the Y-axis on the beam. In this example, the horizontal moving frame 323 is moved by a motor and a gear rack structure. The lifting plate 321 is mounted on the horizontal moving frame 323 by a motor and a ball screw, thereby realizing the lifting and lowering movement of the lifting plate 321. It also includes a laser emitting assembly, specifically including the laser emitting head 322. This structure and principle for glass cutting using laser emission is a conventional technology in the prior art and will not be described in detail here.

[0080] When this laser cutting and grinding equipment for glass processing is in operation, the glass plate is first supported by the rollers on the end guide assembly 21 and guided to the middle of the bed 1. It is then conveyed by the conveyor 223 of the middle conveying and positioning assembly 22 and accurately positioned by the blocking cylinder 225 and the positioning wheel 228. Subsequently, the conveyor 223 moves down, so that the glass plate falls on the support head 226 and remains stationary. Then, the blocking cylinder 225 clamps the glass, thereby fixing the glass. After the laser processing unit 3 is started, the laser cutting component 32 moves along the X and Y axes, and the laser emitting head 322 can move along the Z axis on the lifting plate 321 to perform laser cutting on the glass plate. After cutting, the grinding unit 4 is started, and its grinding component 42, under the action of the grinding cylinder 46 and the rotating seat 45, feeds along the X or Y axis and drives the grinding blade 423 to rotate, thereby achieving grinding treatment on the glass edge. During the feeding process, the first spring 484 and the second spring 493 in the protective component can play a safety buffer role to prevent the grinding blade 423 from forming a rigid collision with the glass. After processing is completed, the conveyor 223 rises again to guide the glass plate to the end guide component 21, thereby realizing a continuous processing flow of automatic feeding, positioning, cutting, grinding and unloading of the glass plate.

[0081] 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.
