Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and in particular to laser marking equipment. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In industrial production, laser scribing equipment, as an important tool for precision machining, is widely used for scribing brittle material substrates such as glass and semiconductors to achieve precise cutting and separation of materials. In practical production applications, traditional laser scribing equipment typically consists of a vertical scribing machine and a horizontal scribing machine, which work together to perform scribing operations on the product along the vertical and horizontal directions, respectively, to meet the cutting needs in different directions.

[0004] Currently used laser marking equipment typically has the capability to mark multiple vertical lines on a product at once, thus improving production efficiency. However, during operation, the multiple internal reflective components can often only be adjusted synchronously, rather than individually to meet the differentiated needs of the actual processing scenario. While this synchronous adjustment method ensures ease of operation to some extent, it significantly limits the equipment's applicability and flexibility when facing complex and varied processing tasks.

[0005] Therefore, how to design a laser scribing device that can take into account both the overall adjustment and individual adjustment of each reflective component has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a laser marking device that can simultaneously adjust both the overall and individual components of each reflective element.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a laser marking device, comprising a base, wherein the following are sequentially arranged on the base:

[0008] The vertical line drawing mechanism includes a plurality of reflective components arranged laterally and a laser for emitting laser light to each reflective component. The plurality of reflective components are configured to move laterally as a whole, and each reflective component is configured to move laterally independently relative to the other reflective components. It is also capable of reflecting the laser light onto the product when it passes by.

[0009] The marking mechanism can move along the X-axis and generates laser light to mark horizontal lines on the product.

[0010] Furthermore, the vertical line drawing mechanism also includes a platform slide, on which each of the reflective components is sequentially arranged;

[0011] The first driving device is located at the bottom of the platform slide and can drive the entire platform to move laterally.

[0012] Multiple second driving devices are disposed on the platform slide and connected to each of the reflective components in a corresponding manner. The second driving devices can drive the reflective components connected to them to move laterally.

[0013] Furthermore, the reflective component includes:

[0014] A first sliding plate is horizontally slidably arranged on the platform slide, with one end of the first sliding plate extending out of the platform slide, and a second driving device supporting the first sliding plate;

[0015] The second sliding plate is vertically connected to the end of the first sliding plate that extends out of the platform slide;

[0016] A first reflector is mounted on the first sliding plate;

[0017] The second reflector is disposed on the first sliding plate and is coaxial with the first reflector;

[0018] A focusing lens is mounted on the second sliding plate and is coaxial with the first reflector.

[0019] Furthermore, the number of the second reflectors is 2N, which are arranged symmetrically in the lateral direction. The closer the second reflector is to the center line of the platform slide, the farther it is from the coaxial first reflector.

[0020] Furthermore, the platform slide includes a horizontally arranged first plate and a vertically arranged second plate, with the second plate disposed at one end of the first plate near the second sliding plate;

[0021] A first lateral guide assembly is provided between each of the first sliding plates and the first plate body;

[0022] A second lateral guide assembly is provided between each of the second sliding plates and the second plate body;

[0023] Furthermore, at least two of the first lateral guide components are provided.

[0024] Furthermore, both the first and second driving devices are magnetic levitation driving devices.

[0025] Furthermore, the reflective component also includes a third driving device;

[0026] The third driving device is disposed on the second sliding plate and can drive the focusing lens to move in the vertical direction.

[0027] Furthermore, it also includes:

[0028] A camera assembly is disposed at the moving end of the horizontal line drawing mechanism and can move synchronously with the horizontal line drawing mechanism as it moves along the X-axis.

[0029] Furthermore, the horizontal line drawing mechanism includes:

[0030] The fourth driving device is mounted on the base and is used to drive its moving end to move along the X-axis direction;

[0031] A laser head assembly, which is disposed at the moving end of the fourth drive device, is used to generate and emit laser light;

[0032] A focusing lens assembly is disposed at the moving end of the fourth driving device and is coaxially distributed with the laser head assembly to focus the laser emitted by the laser head assembly as it passes by.

[0033] A reflector assembly is disposed at the moving end of the fourth drive device and is coaxially distributed with the focusing lens assembly to reflect the laser onto the product when the laser is focused there.

[0034] The beneficial effects of this utility model are reflected in:

[0035] In this invention, by driving multiple reflective components to move laterally on the base, the multiple reflective components can be adjusted together and cooperate with the laser to scribing lines on the product. By driving each reflective component to move laterally relative to other reflective components, each reflective component can be adjusted individually according to the differentiated needs of the actual processing scenario. The laser emits laser light to each reflective component, and the scribing mechanism scribing lines on the product can effectively improve its applicability and flexibility, so as to cope with complex and ever-changing processing tasks.

[0044] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0045] Please see Figure 1-6 This utility model discloses a laser marking device, including a base 1. A vertical line marking mechanism 2 and a horizontal line marking mechanism 3 are sequentially arranged on the base 1. The vertical line marking mechanism 2 includes a plurality of reflective components 20 arranged horizontally and a laser (not shown in the figure) for emitting laser light to each reflective component 20. The plurality of reflective components 20 are configured to move horizontally as a whole, and each reflective component 20 is configured to move horizontally independently relative to other reflective components 20. It can also reflect the laser light onto the product when it passes by. The horizontal line marking mechanism 3 can move along the X-axis of the base 1. It can generate laser light and use it to mark horizontal lines on the product. The laser light mentioned above is common knowledge in the field, so its specific structure and working principle will not be described in detail in this article.

[0046] In practice, by driving multiple reflective components 20 to move laterally on the base 1, the multiple reflective components 20 can be adjusted together and cooperate with the laser to scribing the product. By driving each reflective component 20 to move laterally relative to other reflective components 20, each reflective component 20 can be adjusted individually according to the differentiated needs of the actual processing scenario. The laser emits laser light to each reflective component 20, and the scribing mechanism 3 scribing the product can effectively improve its applicability and flexibility, so as to cope with complex and ever-changing processing tasks.

[0047] In one embodiment, the vertical line drawing mechanism 2 further includes a platform slide 21, which is slidably mounted on the base 1. Each reflective component 20 is sequentially mounted on the platform slide 21. A first driving device 22 is provided at the bottom of the platform slide 21, which can drive the platform slide 21 as a whole to move laterally. A second driving device 23 is mounted on the platform slide 21, which is connected to each reflective component 20 in a one-to-one correspondence. The second driving device 23 can drive the reflective component 20 connected to it to move laterally.

[0048] In practice, by controlling the start of the first drive device 22, the platform slide 21 can move along its X-axis on the base 1. By controlling the start of the second drive device 23, each reflective component 20 can move laterally relative to other reflective components 20. This method allows for both synchronous and individual adjustment of the spacing, thereby improving its applicability.

[0049] In one embodiment, the reflective assembly 20 includes a first sliding plate 201, which is horizontally slidably arranged on a platform slide 21. One end of the first sliding plate 201 extends out of the platform slide 21. A second driving device 23 supports the first sliding plate 201. A second sliding plate 202 is vertically connected to the end of the first sliding plate 201 that extends out of the platform slide 21. A first reflector 204 and a second reflector 203 are mounted on the first sliding plate 201, and each second reflector 203 is coaxially arranged with the corresponding first reflector 204. A focusing lens 205 is mounted on the second sliding plate 202, which is coaxial with the first reflector 204.

[0050] In practice, the laser emits multiple laser beams to each of the second reflectors 203, and each of the second reflectors 203 reflects them to the corresponding first reflector 204. The first reflector 204 reflects them to the corresponding focusing lens 205, and the focusing lens 205 focuses the laser beams onto the product, thereby enabling the product to be scribed.

[0051] In one embodiment, there are 2N second reflectors 203 arranged symmetrically in the lateral direction. The closer the second reflector 203 is to the center line of the platform slide 21, the farther it is from the coaxial first reflector 204.

[0052] This design allows the laser beams, which are divided into multiple beams, to illuminate the corresponding second reflector 203 without interfering with each other, thus facilitating practical use.

[0053] In one embodiment, the platform slide 21 includes a horizontally arranged first plate 211 and a vertically arranged second plate 212. The second plate 212 is installed at one end of the first plate 211 near the second sliding plate 202. A first lateral guide component is provided between each first sliding plate 201 and the first plate 211, and a second lateral guide component is provided between each second sliding plate 202 and the second plate 212. At least two first lateral guide components are provided. The first lateral guide components and the second lateral guide components are used to guide each first sliding plate 201 and the second sliding plate 202 to slide in the corresponding direction.

[0054] In one embodiment, both the first driving device 22 and the second driving device 23 are magnetic levitation driving devices.

[0055] This design enables the platform slide 21 or reflective component 20 to have advantages such as frictionless movement, high precision, high stability, and low noise when moving, and can achieve high-speed and stable linear motion. At the same time, it significantly improves the service life and operating efficiency of the equipment. This magnetic levitation drive device is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0056] In one embodiment, the reflective assembly 20 further includes a third driving device 206, which is mounted on the second sliding plate 202 and can drive the focusing lens 205 to move in the vertical direction.

[0057] In specific implementation, the third driving device 206 can be a motor device, which can drive the focusing lens 205 to move closer to or further away from the first reflector 204. In use, a distance sensor can be installed on the reflective assembly 20 to measure the distance from the product to the focusing lens 205 and compare it with the focal length of the focusing lens 205. The position of the focusing lens 205 can be precisely adjusted by the third driving device 206, so that the focal length can be adjusted in real time during the production process.

[0058] In one embodiment, the device further includes a camera assembly 4, which is mounted on the moving end of the horizontal line drawing mechanism 3 and is able to move synchronously with the horizontal line drawing mechanism 3 as it moves along the X-axis.

[0059] This design integrates the horizontal marking mechanism 3 and the vertical marking mechanism 2 onto the base 1. When working, the horizontal marking mechanism 3 can mark horizontal lines on the product, and together with the vertical marking mechanism 2, it can perform all-round marking processing on the product. Compared with two separate marking devices, it effectively improves the integration of the equipment, reduces the space occupation rate, and facilitates installation and deployment. The camera component 4 can perform image recognition on the marking area to ensure the marking accuracy.

[0060] In one embodiment, the horizontal line drawing mechanism 3 includes a fourth driving device 31, a laser head assembly 32, a focusing lens assembly 33, and a reflector assembly 34. The fourth driving device 31 is mounted on the base 1 to drive its moving end to move along the X-axis. The laser head assembly 32 is mounted on the moving end of the fourth driving device 31. The focusing lens assembly 33 is mounted on the moving end of the fourth driving device 31 and is coaxially distributed with the laser head assembly 32. The reflector assembly 34 is mounted on the moving end of the fourth driving device 31 and is coaxially distributed with the focusing lens assembly 33, used to reflect the laser beam onto the product when it is focused at that point.

[0061] In practice, the laser head assembly 32 generates and emits a laser. The laser passes through the focusing lens assembly 33, which focuses and emits it to the reflector assembly 34. The laser is then reflected onto the product by the reflector assembly 34. At the same time, the fourth driving device 31 drives the laser to draw horizontal lines on the product. The camera assembly 4 can also move synchronously with the laser to facilitate practical use.

[0062] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0063] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0064] Additionally, "multiple" refers to two or more.
