Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of vehicle printing, and in particular to a laser printing mechanism and a laser printing system. Background Art

[0002] In the field of automobile manufacturing, the printing of identification codes for key components such as engine assemblies, frame beams and seat beams is an indispensable part. Among them, the identification code on the frame beam is particularly important, which uses a 17-character VIN code. This VIN code records the production information of the vehicle in detail, including the manufacturer, production year, model, body type and code, engine code and assembly location, etc., which plays a vital role in the tracking and tracing of the frame beam.

[0003] The commonly used VIN code marking methods currently have some obvious shortcomings. First of all, although the pneumatic marking machine can engrave the VIN code on the car beam, because it uses a pneumatic needle for operation, the needle wears out quickly and needs to be replaced frequently. In addition, there is a method of directly pasting the paper QR code, which not only increases the labor cost and the production cost of the paper version of the QR code, but also affects the production efficiency. In addition, the pneumatic needle is in direct contact with the beam, and the vibration generated may cause the marking head to loosen, thereby affecting the marking quality and increasing the cost of rework. At the same time, because the marking head itself is heavy, the labor intensity of the workers during the operation is also relatively large. Utility Model Content

[0038] Embodiment 1

[0039] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides a laser printing mechanism, comprising:

[0040] Base 1;

[0041] A mechanical arm 2, wherein the mechanical arm 2 comprises a mechanical arm 2 body, wherein the mechanical arm 2 body comprises a mechanical fixed end 21 and a mechanical movable end 22, and the mechanical fixed end 21 is fixed to the base 1;

[0042] A connecting mechanism 3, the connecting structure is installed on the mechanical moving end 22;

[0043] A laser printing module 4, which is installed at the connecting mechanism 3 and is used to print the workpiece to be printed;

[0044] A camera module 5, wherein the camera module 5 is installed at the connecting mechanism 3;

[0045] The control module, the laser printing module 4, the robotic arm 2 and the camera module 5 are all electrically connected to the control module, the camera module 5 is used to transmit the acquired workpiece image to the control module, and the robotic arm 2 is used to move according to the movement signal transmitted by the control module.

[0046] In this embodiment, the robot arm 2 usually has multi-axis degrees of freedom, which means that they can be positioned with high precision in three-dimensional space. This flexibility and accuracy are essential for laser printing, because it requires precise control of the position of the laser head to ensure high-quality printing results. The robot arm 2 can be customized according to specific application requirements, for example, additional joints can be added or its working range can be adjusted to meet different production environments and task requirements. In contrast, module robots may be more standardized in design, limiting their applicability and flexibility. Due to the high flexibility and precision of the robot arm 2, they are able to perform complex motion trajectories and tasks, which may be beyond the capabilities of the module robot. The robot arm 2 can perform precise printing on irregular surfaces or perform tasks that require delicate operations. In the above scheme, the combination of the camera module 5 and the robot arm 2 provides real-time visual feedback, enabling the system to automatically correct the printing position and path, and improve the level of automation. The flexibility of the robot arm 2 allows the camera module 5 to acquire images from different angles, thereby providing more comprehensive monitoring of the work area.

[0047] Robotic arms 2 are typically more compact in design, with a small footprint, making them suitable for operation in limited spaces. This is particularly important in laser printing environments, where space efficiency directly affects the layout and cost of the production line. Robotic arms can be programmed and reprogrammed to adapt to different tasks and workpieces, making them highly adaptable in production environments. In contrast, modular robots may require physical changes or hardware replacement to adapt to new tasks.

[0048] More preferably, the connecting mechanism 3 includes a first connecting member 31 and a second connecting member 32, the first connecting member 31 and the second connecting member 32 are detachably installed, the first connecting member 31 is fixed to the moving end of the robotic arm 2, and the second connecting member 32 is provided with a first mounting position and a second mounting position, the laser printing module 4 is detachably installed on the second connecting member 32 through the first mounting position, and the camera module 5 is installed on the second connecting member 32 through the second mounting position.

[0049] This technical solution realizes the rapid switching and maintenance of the laser printing module 4 and the camera module 5 through the design of a detachable connecting mechanism 3, thereby improving the flexibility and working efficiency of the equipment. The detachable connection method allows the laser printing module 4 and the camera module 5 to be quickly disassembled and maintained or replaced when a failure occurs or an upgrade is required, thereby reducing downtime and improving production efficiency. Since the design of the connecting mechanism 3 allows for rapid disassembly and installation, the operator can complete the position adjustment of the laser printing module 4 and the camera module 5 in a short time to adapt to different printing tasks and workpiece requirements. The first connecting member 31 is fixed to the moving end of the robot arm 2, and the second connecting member 32 is provided with a special first mounting position and a second mounting position. Such a design ensures the stability of the laser printing module 4 and the camera module 5 during operation, thereby ensuring the printing quality and accuracy.

[0050] More preferably, the camera module 5 and the laser printing module 4 are arranged in parallel.

[0051] The technical effect of the parallel arrangement of the camera module 5 and the laser printing module 4 is to improve the accuracy and stability of the measurement. The laser printing module 4 and the camera module 5 arranged in parallel can adjust their relative positions and angles according to actual needs to adapt to different working distances and field of view requirements. This flexibility enables the device to cope with a wider range of measurement scenarios and application challenges. The real-time self-calibration method based on parallel laser ranging can use a high-precision laser rangefinder to continuously measure during the image capture process to obtain real-time position information on the surface of the object being measured. This method simplifies the complex operations that rely on external features, special postures and calibration objects in traditional image calibration, and improves the efficiency and accuracy of calibration. On the basis of the parallel setting, by quantitatively analyzing factors such as laser ranging error, laser inclination error, and bias error, the key factors affecting the measurement accuracy can be found, and corresponding error avoidance methods can be adopted to further improve the measurement performance of the system.

[0052] More preferably, it further includes a visual light source module 6 electrically connected to the control module, and the visual light source module 6 is used to provide an illumination source for the camera module 5 ; the visual light source module 6 is arranged on one side of the second connecting member 32 through a fixing component 7 .

[0053] By adding a visual light source module 6 electrically connected to the control module to the laser printing mechanism, the mechanism can provide higher quality image acquisition and processing capabilities, thereby improving the overall measurement accuracy and system reliability. The visual light source module 6 provides lighting for the camera module 5, which helps to obtain images with high contrast, good uniformity, and true reflection of the characteristics of the object being measured. This is crucial for subsequent image analysis and processing, because good image quality is the basis for accurate measurement and identification. The flexibility of the visual light source module 6 allows it to adapt to a variety of application requirements, such as by adjusting the angle or intensity of the light source to adapt to different workpieces and environmental conditions. This adaptability enables the laser printing mechanism to be more widely used in different industrial scenarios. The design of the visual light source module 6 takes into account the coordination with the camera module 5, as well as how to maximize the measurement accuracy and reliability of the system. This not only improves the functionality of the equipment, but also may reduce long-term operating costs.

[0055] The solution of this embodiment positions one end of the visual light source module 6 through the fixing hole 71, which can achieve precise installation and ensure the stability and accuracy of the light source module. The arc hole 72 design allows fine adjustment of the other end of the visual light source module 6, which allows the light source module to be adjusted according to actual needs to adapt to different working environments and conditions. The symmetrically arranged fixings make the installation process easier, and the operator can quickly complete the installation and adjustment of the visual light source module 6. Accurate positioning and flexible adjustment capabilities help to improve the work efficiency and print quality of the entire laser printing mechanism.

[0056] During specific implementation, two fixing holes 71 may be provided on both sides. However, the design method of providing two fixing holes 71 will enable the user to determine the optimal angle when performing specific position configuration, so as to achieve the desired effect.

[0057] More preferably, the control module includes a first control module electrically connected to the robot arm 2 , a second control module electrically connected to the laser printing module 4 , and a third control module electrically connected to the camera module 5 .

[0058] This technical solution achieves higher control accuracy and system stability by subdividing the control module into three sub-control modules electrically connected to the mechanical arm 2, the laser printing module 4 and the camera module 5. This separate design of the control module not only improves the control accuracy and system stability of the laser printing mechanism, but also improves the maintenance efficiency and system flexibility, thereby providing better technical effects in practical applications.

[0059] More preferably, the camera module 5 is also configured to identify the external environment and transmit the obtained identification signal to the control module, so that the control module moves the laser printing module 4 to above the surface of the workpiece to be printed according to the identification signal; wherein the identification signal includes: the position of the workpiece to be printed and the relative position of the laser printing module 4 and the surface of the workpiece to be printed.

[0060] This technical solution uses the camera module 5 to identify the external environment and transmits the obtained identification signal to the control module, so that the control module can move the laser printing module 4 to the surface of the workpiece to be printed according to the identification signal, thereby achieving accurate printing. The transmission and processing of the identification signal provides the prerequisite for laser printing, ensures the smooth progress of the printing process, and optimizes the entire workflow. This technical solution realizes the precise positioning and automatic operation of the laser printing module 4 through the environmental identification function of the camera module 5 and the synergy with the control module, improves the printing accuracy and efficiency, and enhances the adaptability of the equipment and the continuity of the workflow.

Users can directly select the image they want to print through the print selection module, which greatly simplifies the printing process and allows users to quickly perform printing operations without complicated settings or conversion steps. The close integration of the print selection module with the control module and the laser printing module 4 ensures that once the user selects the print image, the control module can respond quickly and command the laser printing module 4 to start working, which improves the efficiency of the entire printing process. The addition of the print selection module enables the laser printing mechanism to not only perform precise printing tasks, but also customize printing according to the user's personalized needs, increasing the functional diversity of the system.

[0063] The embodiment of the utility model realizes the automation of the printing process by integrating the manipulator arm 2, the laser printing module 4 and the camera module 5.
