Description
Technical Field
[0001] This utility model belongs to the technical field of laser engraving and inspection equipment, and in particular relates to a multi-lens laser engraving device. Background Technology
[0002] With the widespread use of mobile communication devices, mobile phones have become indispensable and convenient electronic devices in people's daily lives. In the functioning and use of mobile phones, SIM cards and memory cards are core supporting components. SIM cards are used to register and store important user data and information, while memory cards are used to expand the phone's data storage capacity. Both SIM cards and memory cards require a card tray for stable assembly and connection with the card slot connector in the phone. Therefore, the card tray has become an essential functional component in mobile terminals, and its market demand and supply are constantly increasing.
[0003] In the manufacturing process of SIM card trays, laser engraving is a necessary step to ensure functional identification, production traceability, and assembly compatibility. The laser engraving content typically includes card type identification symbols (such as SIM card identification), production item numbers, production date codes, and color differentiation codes. However, the laser engraving area of the SIM card tray has a composite structure of metal and plastic materials, and laser engraving needs to be performed on both the front and back sides. Due to the differences in material properties, the metal area requires red laser engraving, while the plastic area requires violet laser engraving; both must be completed using different optical systems.
[0004] In existing technologies, cassette laser engraving largely relies on single-lens laser engraving equipment. This process has significant drawbacks: after laser engraving the metal area on one side of the cassette, the cassette material strip needs to be manually transferred from the current equipment to another single-lens equipment adapted for plastic laser engraving. This process requires not only manual loading and unloading of the material strip but also readjustment of equipment parameters for plastic laser engraving requirements. If laser engraving on the reverse side of the cassette is required, the above manual material change and equipment adjustment process must be repeated, resulting in a single cassette laser engraving requiring two or more machine adjustments and multiple manual material changes. This production model, on the one hand, significantly reduces the overall production efficiency of cassette laser engraving due to the numerous manual interventions and long equipment adjustment times, making it difficult to meet the market's demand for mass production. On the other hand, the multiple material changes and machine adjustments can easily lead to problems such as cassette positioning deviations and material strip damage, significantly increasing the defect rate of laser engraving. This, in turn, results in high material and labor costs in cassette production, hindering the efficient and large-scale development of the cassette manufacturing industry. Utility Model Content
[0005] The purpose of this invention is to provide a multi-lens laser engraving device, which aims to solve the problems of low production efficiency, high defect rate and high material loss cost caused by multiple manual material changes and equipment debugging in the existing single-lens laser engraving process.

[0010] In some embodiments, both the first and third laser engraving devices are configured with red laser engraving lenses for laser engraving the metal area of the card tray, and the second laser engraving device is configured with a violet laser engraving lens for laser engraving the plastic area of the card tray.

This invention enables automatic switching between laser engraving processes on the metal and plastic areas of the card slot by setting laser engraving lenses of different wavelengths in the laser engraving component, significantly improving the production efficiency of card slot laser engraving. Through the electrical linkage between the detection component and the cutting component, real-time detection of laser engraving quality is achieved, effectively improving the yield rate and reducing material loss.
[0021] In some embodiments, the console 10 is a cubic or cuboid frame structure, used to fix and support the feeding and positioning component 11, the feeding drive component 12, the laser engraving component 13, the detection component 14, the cutting component 15, the receiving drive component 16, and the receiving and positioning component 17. The console 10 includes a support frame 101, a support column 102, and a positioning seat 103. The support frame 101, the support column 102, and the positioning seat 103 are all fixed on the table surface of the console 10, and are used to provide stable support and positioning for different components.

The positioning seat 103 can be set as a semi-enclosed cuboid structure with one side open, and is fastened to the table surface of the console 10 for embedded installation of the receiving drive component.
[0022] In some embodiments, the feeding and positioning assembly 11 includes a feeding tray 111 and a feeding guide groove 112. The feeding tray 111 is disposed above the feeding guide groove 112. The tray material to be laser-engraved is drawn out from the feeding tray 111 and guided and limited by the feeding guide groove 112. The feeding tray 111 is generally circular and is rotatably mounted on the support frame 101. The feeding guide groove 112 is a cuboid groove structure with openings at both ends. The outer entrance end of the feeding guide groove 112 is provided with a first arc-shaped transition structure 1121. The first arc-shaped transition structure 1121 is used to achieve a smooth transition of the tray material from the feeding tray 111 to the feeding guide groove 112, effectively reducing the frictional resistance and stress experienced by the material when turning. The feeding guide groove 112 is fixedly set below the feeding tray 111. The card tray material to be laser engraved is first wound and placed on the feeding tray 111. After being released by the rotation of the feeding tray 111, it is introduced from one end of the feeding guide groove 112. After being guided and limited by the groove, it is led out from the other end and stably conveyed to the receiving positioning component 17.
[0023] Please refer to the following: Figure 3 In some embodiments, the feeding drive assembly 12 includes a feeding driver 121 and a first conveyor belt 122, with the main body of the feeding driver 121 disposed inside the positioning seat 103. Multiple feeding drivers 121 can be configured as needed, arranged linearly on one side of the first conveyor belt 122, to provide conveying power and drive the first conveyor belt 122 to move continuously and stably. The first conveyor belt 122 is erected along a preset path between the unloading positioning assembly 11 and the receiving positioning assembly. Its surface can be provided with suitable limiting flanges or anti-slip textures according to the shape of the tray material, to carry and orient the tray material, ensuring that the tray can be smoothly conveyed during laser engraving.
[0024] Please refer to the following: Figures 5 to 6In some embodiments, the laser engraving assembly 13 includes a first laser engraving device 131, a second laser engraving device 132, and a third laser engraving device 133 arranged sequentially. The first laser engraving device 131 is mounted at a preset station above the first conveyor belt 122 and is used to laser engrave the metal area on the front of the card tray. The second laser engraving device 132 and the third laser engraving device 133 are located at preset stations above the second conveyor belt 162 and are used to laser engrave the plastic and metal areas on the back of the card tray, respectively. Specifically, the first laser engraving device 131 includes a first laser engraving lens 1311 and a first laser 1312; the second laser engraving device 132 includes a second laser engraving lens 1321 and a second laser 1312; and the third laser engraving device 133 includes a third laser engraving lens 1331 and a third laser 1332. The first laser engraving device 131, the second laser engraving device 132, and the third laser engraving device 133 are respectively installed on the movable sliders 1021 of different support columns 102. The movable sliders 1021 are controlled to move up and down by the lifting shaft 1022 on the support column 102, so that the height position of each lens can be flexibly adjusted to adapt to the laser engraving area requirements of different card tray products, ensuring the accuracy and adaptability of card tray laser engraving.
[0025] In some embodiments, the first laser engraving device 131 and the third laser engraving device 133 are both configured with red laser engraving lenses for laser engraving on the metal area of the card tray, while the second laser engraving device 132 is configured with a violet laser engraving lens for laser engraving on the plastic area of the card tray. The first and third laser engraving devices 131 and 133 can quickly engrave the SIM card identifiers (SIM1, SIM2) and symbols on the metal area of the card tray without causing excessive heat damage to the metal surface. The second laser engraving device 132 can achieve clear character or pattern laser engraving on the plastic area, such as production item numbers, production date codes, color differentiation codes, etc., while avoiding deformation or carbonization of the plastic due to high temperatures. Through the coordinated layout and differentiated laser configuration of the first, second, and third laser engraving devices 131 and 132, the laser engraving assembly 13 enables the completion of all laser engraving processes on different material areas of the card tray in a single continuous transport process, eliminating the need for manual material changes or machine readjustment midway, significantly improving the efficiency and accuracy of laser engraving processing.
[0026] Please refer to the following: Figure 7 In some embodiments, the detection component 14 includes a first detection component 141 and a second detection component 142. The first detection component 141 is located above the first conveyor belt 122 and to the right of the first laser engraving device 131, and the second detection component 142 is located above the second conveyor belt 162 and to the right of the third laser engraving device 133. The first detection component 141 and the second detection component 142 are used to perform quality inspection on the areas after laser engraving on the front and back of the card tray, respectively.
[0027] In some embodiments, the first detection component 141 includes a first detection seat 1411, a first detection lens 1412, and a first detection light source 1413. The first detection lens 1412 is mounted above the first detection seat 1411. A first through hole 14111 is provided on the first detection seat 1411. The light emitted by the first detection light source 1413 is projected onto the first area to be detected through the first through hole 14111. The first detection base 1411 and the first detection lens 1412 are slidably mounted and fixed on the support frame 101, and their height can be finely adjusted according to the detection requirements. The first detection lens 1412 adopts an industrial camera and is vertically mounted directly above the first detection base 1411. The first detection base 1411 has a first through hole 14111 in the middle that matches the field of view of the lens. The first detection light source 1413 is installed around the first through hole 14111. The uniform light emitted by it is vertically projected through the first through hole 14111 onto the first area to be detected on the front of the card tray, effectively eliminating the interference of reflection from the metal surface and providing stable lighting conditions for image acquisition.
[0028] In some embodiments, the second detection component 142 includes a second detection seat, a second detection lens, and a second detection light source. The second detection lens is mounted above the second detection seat, and the second detection seat has a second through hole. Light emitted by the second detection light source is projected onto the second area to be detected through the second through hole. The assembly method of the second detection seat, the second detection lens, and the second detection light source is the same as that of the first detection seat 1411, the first detection lens 1412, and the first detection light source 1413. The second detection lens provides a uniform and bright illumination environment to ensure image acquisition quality. The first detection component 141 and the second detection component 142 can respectively perform real-time detection of the laser engraving effect on the front and back of the tray during the conveying process, effectively identifying laser-engraved defective products and providing a basis for judgment in subsequent cutting processes.
[0029] In some embodiments, the cutting assembly 15 includes a first cutting mechanism 151 and a second cutting mechanism 152. The first cutting mechanism 151 is located to the right of the first detection assembly 141, and the second cutting mechanism 152 is located to the right of the second detection assembly 142. The first cutting mechanism 151 is correspondingly located on the first conveyor belt 122 and is used to initially cut the card tray strip that has completed front-side laser engraving and quality inspection. The second cutting mechanism 152 is correspondingly located on the second conveyor belt 162, opposite to the first cutting mechanism 151, and is used to perform final shaping and cutting of the card tray strip that has completed all laser engraving processes. The first cutting mechanism 151 and the second cutting mechanism 152 can respectively adopt pneumatic or servo-driven punching modules, with precision blades or laser cutting heads mounted at their execution ends. When the detection assembly detects a laser-engraved defective product, the cutting assembly 15 receives a cutting command and drives the first cutting mechanism 151 or the second cutting mechanism 152 to move rapidly, cutting off the defective card tray. The cut defective product can be automatically removed by an additional negative pressure adsorption device. The qualified card trays cut by the second cutting mechanism 152 are then conveyed to the next process, while the unqualified products are simultaneously pushed to the waste box to avoid interfering with the subsequent conveyor belt and processing. This achieves online, real-time, and automatic rejection of defective products with laser engraving on both sides, reduces ineffective cutting losses, ensures the overall quality of the final product, and avoids the efficiency loss and secondary damage risk caused by traditional manual rejection methods.
[0030] Please refer to the following: Figure 3 In some embodiments, the take-up drive assembly 16 includes a take-up driver 161 and a second conveyor belt 162. The feed driver 121 and the take-up driver 161 are respectively connected to the opposite sides of the first conveyor belt 122 and the second conveyor belt 162. The feed driver 121 and the take-up driver 161 operate synchronously, cooperating to drive the first conveyor belt 122 and the second conveyor belt 162 to transport the tray material carried on the unloading positioning assembly 11 along a preset path to the take-up positioning assembly 17. Specifically, multiple take-up drivers 161 can be configured as needed, arranged linearly on the side of the second conveyor belt 162 opposite to the feed driver 121, to avoid mutual interference between the two drivers in the installation space. The feeding driver 121 and the receiving driver 161 provide conveying power together with the same linear speed and direction, ensuring that the second conveyor belt 162 maintains a continuous and stable motion. The second conveyor belt 122 is arranged side by side with the first conveyor belt 122 and is erected between the feeding positioning component 11 and the receiving positioning component along a preset path. Its surface can be set with matching limiting flanges or anti-slip textures according to the shape of the card tray material belt, which is used to carry and orient the card tray material belt and realize its precise orientation transmission, preventing deviation or slippage during the conveying process.
[0031] In some embodiments, the receiving and positioning assembly 17 includes a receiving tray 171 and a receiving guide groove 172. The receiving tray 171 is disposed above the receiving guide groove 172. The laser-engraved tray strip is guided and limited by the receiving guide groove 172 and is wound into the receiving tray 171 by rotation. The receiving and positioning assembly 17 and the unloading and positioning assembly 11 are symmetrically disposed at the left and right ends of the control console 10. The receiving tray 171 is generally circular and is rotatably mounted on the support frame 101. The receiving guide groove 172 is a cuboid groove structure with openings at both ends. The outer exit end of the receiving guide groove 172 is provided with a second arc-shaped transition structure 1721. The second arc-shaped transition structure 1721 is used to achieve a smooth transition of the tray strip from the receiving guide groove 172 to the receiving tray 171. The receiving guide groove 172 is fixedly installed below the receiving tray 171. The laser-engraved tray material is introduced from one end of the receiving guide groove 172, guided and limited by the groove, and then smoothly led out from the other end. Finally, it is wound and stored on the tray by the rotational motion of the receiving tray 171. The feeding positioning component 17 and the feeding positioning component 11 are symmetrical in structure and are respectively set at the left and right ends of the control console 10, forming a continuous and stable material conveying and recycling path, realizing a fully closed-loop automated flow of the tray laser engraving process.
[0032] In some embodiments, the multi-laser-engraved lens device further includes a flipping mechanism (not shown) disposed between the first conveyor belt 122 and the second conveyor belt 162. The flipping mechanism is used to drive the card tray material belt to rotate 180° around the transverse axis after the front side of the card tray is laser-engraved and cut, so that the front and back sides of the card tray material belt are reversed. After the reversal is completed, the card tray material belt is received by the second conveyor belt 162 and transported to the reverse side laser-engraved area.
[0033] In some embodiments, the multi-laser engraving lens further includes a laser engraving host (not shown) and a display (not shown). The laser engraving host is electrically connected to the feeding drive component 12, the laser engraving component 13, the detection component 14, the cutting component 15, and the receiving drive component 16, and is used to send control commands to control the coordinated operation of each component and the setting of laser engraving processing parameters. The display is communicatively connected to the laser engraving host and is used to display the data information of each component and the laser engraving image of the tray in real time. The laser engraving host can set and adjust parameters such as laser power, engraving speed, and engraving depth for laser engraving processing. The display shows the working status, operating data, alarm information, and image comparison of the tray before and after laser engraving of each component in real time, providing operators with an intuitive human-machine interface, facilitating comprehensive monitoring and precise management of the production process.
[0034] In some embodiments, the workflow of the multi-lens laser engraving equipment forms a fully automated processing closed loop from material loading to finished product collection, including the following steps: Feeding and Positioning: The material strip with the laser-engraved card tray to be wound is wound onto the feeding and positioning component 11, and guided and initially positioned by the feeding guide groove 112. Specifically, the operator installs the material tray with the material strip to be laser-engraved onto the feeding tray 111 of the feeding and positioning component 11, pulls the end of the material strip through the feeding guide groove 112, and guides it to the starting end of the first conveyor belt 122, completing the initial feeding of the equipment. At this time, the laser engraving host detects the material strip is in place through the sensor and automatically enters the standby state, and the display synchronously displays the initial parameters of each component of the equipment.
[0035] Frontal Conveying and Laser Engraving: The feeding drive assembly 12 is activated, conveying the card tray material strip to be laser engraved along a preset path to below the first laser engraving device 131. The first laser engraving device 131 performs laser engraving on the metal area on the front of the card tray. Specifically, the feeding drive assembly 12 is activated, and the first conveyor belt 122 drives the card tray material strip forward at a preset speed. When the front end of the material strip reaches the preset station below the first laser engraving device 131, the laser engraving host triggers a laser emission command, and the laser parameters are automatically matched according to the metal material. The first laser engraving device 131 laser engraves the SIM card markings (SIM1, SIM2) and symbols on the metal area on the front of the card tray.
[0036] Frontal quality inspection: The conveyor belt with completed frontal laser engraving continues to be conveyed to the area below the first inspection component 141, where the quality of the laser engraving is judged by visual inspection. Specifically, the tray with completed frontal laser engraving moves with the conveyor belt to the area below the first inspection component 141. The first inspection lens 1412, in conjunction with the first inspection light source 1413, captures images of the laser engraved area. By comparison, it is determined whether the clarity and integrity of the marking meet the standards, and the inspection results are fed back to the laser engraving host in real time.
[0037] Front-side defective product cutting: If the first detection component 141 identifies a defective product, the first cutting mechanism 151 is activated to cut the defective unit out of the conveyor belt. If the first detection component 141 identifies a qualified product, the conveyor belt continues to be conveyed.
[0038] Material belt flipping: The material belt that has completed front-side processing and inspection is rotated 180° at a constant speed around the transverse axis by the flipping mechanism, so that the back side of the card tray faces upward, and then smoothly transitions to the second conveyor belt 162, realizing seamless switching between front and back-side processing.
[0039] Reverse conveying and laser engraving: The receiving drive assembly 16 drives the second conveyor belt 162 to transport the material strip to the reverse laser engraving station. The second laser engraving device 132 and the third laser engraving device 133 respectively perform laser engraving on the plastic and metal areas of the card tray's reverse side. Driven by the receiving drive 161, the second conveyor belt 162 transports the card tray material strip at the same speed as the first conveyor belt 122. First, it passes through the second laser engraving device 132, which emits a low-power laser to engrave information such as the production item number, production date code, and color differentiation code on the plastic area of the card tray's reverse side. The third laser engraving device 133 completes the laser engraving process on the metal area of the reverse side with the same standard as the front side, that is, it laser engraves the SIM card identification (SIM1, SIM2) and symbols on the metal area of the card tray's reverse side.
[0040] Reverse side quality inspection: The material strip with reverse laser engraving completed is conveyed to the second inspection component 142 for reverse laser engraving quality inspection. The card tray with full-area laser engraving completed arrives at the second inspection component 142. The second inspection lens 1422, in conjunction with a switchable spectrum light source, inspects the laser engraving effect on the plastic and metal areas of the card tray's reverse side to ensure that the overall processing quality of the card tray meets the requirements.
[0041] Reverse defective product cutting: If the second detection component 142 identifies a defective product, the second cutting mechanism 152 is activated to cut the defective unit out of the conveyor belt. If the second detection component 142 identifies a qualified product, the conveyor belt continues to be conveyed.
[0042] Material collection and winding: The qualified card tray material is conveyed by the collection drive assembly 16 to the collection positioning assembly 17 and wound into the collection tray 171. The defective products marked with inspection marks are pushed to the waste box by the sorting mechanism after cutting, realizing the automatic separation of good products and waste materials.
[0043] Data Recording and Monitoring: Throughout the entire processing, the laser engraving host records parameters such as laser power, cutting dimensions, and inspection results in real time, and dynamically updates production data via a display. Operators can view the laser engraved images on both sides of the tray in real time via a touchscreen, adjust process parameters, or receive alarm prompts and intervene when equipment malfunctions, ensuring efficient and stable production operation. This achieves continuous laser engraving, inspection, and cutting of the tray strip on both sides, significantly improving the batch production efficiency and quality consistency of the trays.
[0044] This invention provides a multi-lens laser engraving device that integrates feeding, laser engraving, inspection, cutting, and receiving processes into a single production flow through an integrated design. The tray material strip no longer needs to be transferred between multiple machines, effectively shortening the laser engraving material cycle. It also integrates at least two laser engraving lenses of different wavelengths, automatically adapting to and completing laser engraving of both metal and plastic materials on the front and back of the tray. This fundamentally eliminates the time wasted on multiple manual material changes and repeated machine adjustments in traditional processes, significantly improving the production efficiency of tray laser engraving. Furthermore, the feeding drive component and receiving drive component work together to achieve directional and continuous conveying of the tray material strip, avoiding material strip damage that may occur during traditional multiple material changes. The inspection component and cutting component are electrically linked, enabling real-time, automatic detection of laser engraving quality and immediate rejection of defective products, reducing material waste and saving production costs.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
