Description

Technical Field

[0001] This utility model relates to the technical field of glass production, and in particular to a laser engraving defect detection device. Background Technology

[0002] Laser engraving defect detection equipment is an automated inspection device that utilizes high-precision laser scanning and image processing technology to monitor and judge the quality of engraved lines on the surface of various materials in real time. It rapidly scans the engraved area with a laser beam, captures the engraving shape using a high-resolution sensor, and then uses intelligent algorithms to analyze the width, depth, continuity, and positional accuracy of the engraved lines. This allows for the timely detection of various defects such as broken lines, burrs, misalignments, and insufficient depth, significantly improving the inspection efficiency and product consistency of the production line. It is widely used in electronics, optics, automotive, and precision manufacturing industries.

[0003] Currently, commonly used laser engraving defect detection equipment in the industrial field mainly adopts a dynamic online detection mode, where the glass is inspected while moving on a conveyor belt. While this design enables continuous production and meets the efficiency requirements of large-scale inspection, the relative displacement and vibration interference between the laser spot and the engraving line due to the glass's movement can lead to blurred or distorted images, thus affecting the accuracy and stability of defect identification. In contrast, static detection, by fixing the glass position, can obtain clearer images and higher detection accuracy, but it requires frequent start-ups and stops of the conveyor equipment, significantly reducing the inspection cycle and potentially causing secondary damage due to mechanical impact. This makes it difficult to meet the dual demands of efficiency and accuracy in modern production lines. Therefore, how to maintain an efficient and continuous inspection process while ensuring detection accuracy has become a key challenge that current laser engraving defect detection technology urgently needs to address. Utility Model Content

[0004] In view of the problem that the existing technology is unable to achieve an efficient and continuous detection process while ensuring high detection accuracy, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a laser engraving defect detection device, which aims to solve the problem that existing technologies cannot achieve an efficient and continuous detection process while ensuring high detection accuracy.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a laser engraving defect detection device, including a main frame, a conveying mechanism and a detection mechanism, wherein the conveying mechanism includes a drive motor fixedly installed in the main frame, a rotating disk and a shaped disk are rotatably installed on one side of the main frame, a slider is fixedly installed on the side surface of the rotating disk through a connecting rod, a groove is opened on the side surface of the shaped disk, and conveying rollers are rotatably installed on both sides of the upper surface of the main frame, and the shaped disk is fixedly installed on one end of the conveying roller; The detection mechanism includes a first gear, a second gear, and a third gear rotatably mounted on the upper part of one side of the main frame. The side surfaces of the first gear and the second gear are both fixedly mounted with meshing blocks. A rotating shaft is fixedly mounted on one side of the third gear, and a detection device is fixedly mounted on the lower part of the side surface of the rotating shaft.

[0007] In a preferred embodiment of the laser engraving defect detection device of this utility model, the output end of the drive motor is equipped with a drive shaft, and the drive shaft and the rotating disk are connected to each other by a first belt.

[0008] In a preferred embodiment of the laser engraving defect detection device of this utility model, when the conveyor roller rotates, the slider slides within the groove; when the conveyor roller does not rotate, the slider moves away from the groove.

[0009] In a preferred embodiment of the laser engraving defect detection device of this utility model, the conveyor rollers are provided in two sets, and the two sets of conveyor rollers are connected to each other by a conveyor belt.

[0010] In a preferred embodiment of the laser engraving defect detection device of this utility model, the transmission shaft and the first gear are connected to each other by a second belt.

[0011] In a preferred embodiment of the laser engraving defect detection device of this utility model, the first gear and the second gear mesh with each other.

[0012] In a preferred embodiment of the laser engraving defect detection device of this utility model, the third gear meshes with the first gear and the second gear respectively through meshing blocks.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its conveying mechanism, uses a drive motor to rotate a rotating disk via a first belt, causing the connecting rod and slider to slide within the groove of the shaped disk. When the slider slides into the groove, it drives the conveyor roller to rotate at a certain angle, thus conveying the glass to be inspected forward a certain distance via the conveyor belt. When the slider slides out of the groove, the conveyor belt stops conveying, and at the same time, the inspection equipment performs a comprehensive inspection of the glass. This combines the glass conveying and inspection processes into one, achieving automatic alternation between conveying and inspection. This intermittent forward and stationary inspection mode ensures both the high efficiency of continuous production line operation and the high precision of inspection when the glass is stationary, effectively solving the contradiction between efficiency and accuracy in traditional equipment.

[0014] 2. This utility model, through its detection mechanism, enables the drive motor to synchronously rotate the first and second gears in opposite directions via the second belt during the conveying process. The third gear, driven by a meshing block, reciprocates, causing the detection device and rotating shaft to rotate back and forth. While the glass is being conveyed, the detection device slowly rotates backward. When the glass stops, the detection device slowly rotates forward. The detection device performs laser engraving defects on different locations on the glass surface. After detection, the glass continues to be conveyed backward, while the detection device rotates backward to await the next piece of glass to be inspected. This achieves intelligent synchronization between the detection device and the glass conveying process, ensuring that the detection device can completely cover the glass surface and effectively avoiding blind spots. Without requiring additional power, it greatly improves the comprehensiveness and accuracy of a single static inspection. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0018] Reference Figures 1-2This is the first embodiment of the present invention, which provides a laser engraving defect detection device 307. This laser engraving defect detection device 307 includes a main frame 1, a conveying mechanism 2, and a detection mechanism 3. The conveying mechanism 2 includes a drive motor 201 fixedly installed in the main frame 1. A rotating disk 204 and a shaped disk 207 are rotatably installed on one side of the main frame 1. A slider 206 is fixedly installed on the side surface of the rotating disk 204 through a connecting rod 205. A groove 208 is opened on the side surface of the shaped disk 207. Conveying rollers 209 are rotatably installed on both sides of the upper surface of the main frame 1. The shaped disk 207 is fixedly installed on one end of the conveying roller 209.

[0019] The output end of the drive motor 201 is equipped with a drive shaft 202, and the drive shaft 202 and the rotating disk 204 are connected to each other by a first belt 203.

[0020] When the conveyor roller 209 rotates, the slider 206 slides within the groove 208. When the conveyor roller 209 does not rotate, the slider 206 moves away from the groove 208.

[0021] Two sets of conveyor rollers 209 are provided, and the two sets of conveyor rollers 209 are connected to each other by a conveyor belt 210.

[0022] During operation, after the equipment is started, the drive motor 201 begins to run, and its power is transmitted to the rotating disk 204 through the transmission shaft 202 and the first belt 203, causing the rotating disk 204 to perform uniform circular motion. As the rotating disk 204 rotates, it drives the slider 206 to move synchronously via the connecting rod 205, causing the slider 206 to move along a specific trajectory. When the trajectory of the slider 206 coincides with the position of the groove 208 on the shaped disk 207, the slider 206 slides into the groove 208. At this point, the slider 206 forms a mechanical connection with the shaped disk 207, thereby driving the shaped disk 207 and its fixed components. The conveyor roller 209 rotates at a preset angle. The rotation of the conveyor roller 209, through the conveyor belt 210, precisely conveys the glass to be tested forward a fixed distance. When the rotating disk 204 continues to rotate, causing the slider 206 to slide out of the slide groove 208, the connection between the slider 206 and the irregular disk 207 is broken. The conveyor roller 209 loses power and stops rotating. The conveyor belt 210 also stops, and the glass stops at the detection position, waiting for the detection mechanism 3 to perform a comprehensive inspection. After that, the rotating disk 204 continues to rotate, entering the next working cycle. This process is repeated to realize the intermittent conveying of the glass. Example 2

[0023] Reference Figures 3-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the detection mechanism 3 includes a first gear 302, a second gear 303 and a third gear 305 rotatably mounted on the upper part of one side of the main frame 1. The side surfaces of the first gear 302 and the second gear 303 are both fixedly mounted with meshing blocks 304. A rotating shaft 306 is fixedly mounted on one side of the third gear 305. A detection device 307 is fixedly mounted on the lower part of the side surface of the rotating shaft 306.

[0024] The drive shaft 202 and the first gear 302 are connected to each other by the second belt 301.

[0025] The first gear 302 and the second gear 303 mesh with each other.

[0026] The third gear 305 meshes with the first gear 302 and the second gear 303 respectively through the meshing block 304.

[0027] During operation, while the conveying mechanism 2 is running, the power of the drive motor 201 is also synchronously transmitted to the first gear 302 of the detection mechanism 3 through the transmission shaft 202 and the second belt 301. When the first gear 302 rotates, it drives the second gear 303, which meshes with it, to rotate synchronously but in opposite directions. Since meshing blocks 304 are fixedly installed on the side surfaces of both the first gear 302 and the second gear 303, these two counter-rotating meshing blocks 304 will alternately mesh with the third gear 305. When one meshing block 304 pushes the third gear 305, the third gear 305 drives the rotating shaft 306 and the lower... The detection device 307 rotates slowly forward; when the engaging block 304 disengages, another engaging block 304 engages with the third gear 305 from the other side, pushing it to rotate slowly backward. This process is precisely coordinated with the action of the conveying mechanism 2: when the glass moves forward under the drive of the conveyor belt 210, the detection device 307 is slowly rotating backward to reset; when the glass is stationary waiting for detection, the detection device 307 slowly rotates forward to perform scanning detection on the glass surface, thereby realizing the detection of laser engraving defects at different positions of the glass. After the detection is completed, the glass continues to be conveyed, and the detection device 307 also rotates backward in sync, waiting for the next piece of glass.

[0028] The remaining structure is the same as that in Example 1.

[0029] Based on embodiments 1-2, the working principle of this utility model is as follows: The drive motor 201 starts, and its power is distributed through the transmission shaft 202, simultaneously driving the two core mechanisms of conveying and detection. On the conveying path, the power drives the rotating disk 204 to rotate via the first belt 203, causing the slider 206 to move accordingly via the connecting rod 205. When the slider 206 slides into the groove 208 of the shaped disk 207, it drives the shaped disk 207 and the conveyor roller 209 to rotate at a fixed angle, thereby conveying the glass forward a precise distance via the conveyor belt 210. When the slider 206 slides out of the groove 208, the conveyor roller 209 immediately stops, and the glass remains stationary at the detection position. Simultaneously, on the detection path, the power drives the first gear 302 to rotate via the second belt 301, and through gear meshing… The second gear 303 rotates synchronously in opposite directions. The meshing blocks 304 on these two gears alternately mesh with the third gear 305, driving it to reciprocate. This, in turn, drives the inspection device 307 to reciprocate synchronously. The entire process achieves precise timing coordination: when the glass moves, the inspection device 307 slowly rotates backward to reset; when the glass stops precisely, the inspection device 307 begins to slowly rotate forward, performing a comprehensive scanning inspection of the stationary glass surface. After the inspection is completed, the conveying mechanism 2 starts again, conveying the glass to the next distance, while the inspection device 307 also rotates backward synchronously, preparing for the next inspection cycle. This process repeats, perfectly integrating the intermittent conveying of the glass with the reciprocating scanning of the inspection device 307, achieving efficient, accurate, and blind-spot-free automated defect detection.
