Description

Technical Field

[0001] This utility model relates to the field of laser marking robot technology, specifically a laser marking robot that facilitates the replacement of workpiece clamping seats. Background Technology

[0002] Laser marking technology, as one of the important applications in laser processing, occupies a pivotal position in modern industrial production. It utilizes a high-energy-density laser beam to locally irradiate specific areas of a workpiece, triggering vaporization or a chemical reaction that changes the color of the surface material, thereby leaving a permanent, high-quality mark on the workpiece surface. This marking method boasts significant advantages such as high marking accuracy, high speed, and excellent permanence, and is widely used in numerous industries including electronics, machinery, automotive, and aerospace.

[0003] When using laser marking robots to mark workpieces, the clamping base is an indispensable key component. It is used to fix the workpiece in place, ensuring a stable position during marking to guarantee accuracy. However, the design of clamping bases in most laser marking robots currently on the market has significant shortcomings. Most robots' clamping bases are directly bolted to the top of the equipment housing, a method that brings many inconveniences in practical applications. Firstly, when marking different types or sizes of workpieces on the production line requires changing to a matching clamping base. However, due to the bolted installation method, changing the clamping base requires using tools to remove and install a large number of bolts, making the operation cumbersome and time-consuming, severely impacting production efficiency and the applicability of the equipment. For example, in some small parts processing enterprises with a wide variety of products and small order volumes, the time wasted by frequently changing clamping bases may lead to order delivery delays.

[0004] On the other hand, laser marking robots are typically equipped with mobility devices, commonly wheels, to meet the needs of different workstations. While this design improves the robot's maneuverability, it also introduces new problems. Once the robot moves to the designated position via wheels, its structural characteristics and center of gravity distribution mean that stable placement cannot be guaranteed solely by the wheels' contact with the ground. During the marking process, even the slightest tremor can cause deviations in the laser marking position, affecting the quality and accuracy of the marking. This is especially problematic for high-precision marking tasks, such as marking aerospace components or electronic chips; such instability can have catastrophic consequences, leading to product scrap and increased production costs. Therefore, to improve the efficiency and quality of laser marking robots, it is urgent to improve existing technology and design a laser marking robot that facilitates workpiece clamp changes and ensures stable placement after the equipment box is moved. Utility Model Content

[0005] The purpose of this invention is to provide a laser marking robot with an easy-to-change workpiece clamping base, which solves the problems of inconvenient clamping base replacement and unstable placement of the robot after the equipment box is moved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser marking robot that facilitates the replacement of workpiece clamping seats, comprising an equipment box, a robotic arm mounted on the upper end of the equipment box, a laser mounted on the end of the robotic arm away from the equipment box, a clamping seat contacting the upper end of the equipment box, a door hinged to the front of the equipment box, four evenly distributed support frames fixedly connected to the lower end of the equipment box, a stabilizing mechanism provided on the support frames, a connecting plate fixedly connected to the lower end of the clamping seat, two symmetrically distributed fixing plates fixedly connected to the inner top of the equipment box, connecting pins slidably connected inside the fixing plates, a limit frame fixedly connected to the outer side of the connecting pins, a spring provided on the outer side of the connecting pins, a steel wire fixedly connected to the end of the connecting pin away from the limit frame, and a bracket fixedly connected to the inner top of the equipment box.

[0007] Preferably, the connecting plate is slidably connected to the equipment box, and the limiting frame is slidably connected to both the connecting plate and the equipment box. The limiting frame can limit the clamping seat through the connecting plate. The connecting plate connects the clamping seat and the equipment box, and also provides a sliding track and limiting part for the limiting frame. Through its cooperation with the connecting plate, the limiting frame can fix the clamping seat horizontally, preventing unnecessary movement of the clamping seat on the equipment box, ensuring the stability of the clamping seat during operation, and thus ensuring the accurate positioning of the workpiece during marking.

[0008] Preferably, one end of the spring is fixedly connected to the limiting frame, and the other end of the spring is fixedly connected to the fixing plate. The spring can automatically reset the limiting frame through its elastic force. The function of the spring is to provide a continuous pulling or pushing force under normal conditions, keeping the limiting frame in the position that limits the clamping seat. When the clamping seat needs to be replaced, the limiting frame is pulled open against the spring force. Once the clamping seat is installed in place or the replacement operation is completed, the spring force can quickly reset the limiting frame, achieving rapid fixation of the clamping seat and improving the efficiency of clamping seat installation and replacement.

[0009] Preferably, the steel wire is located away from the pull ring seat, and the pull ring seat is slidably connected to the bracket, allowing the pull ring seat to move the steel wire. The pull ring seat is a manually operated component; pulling the pull ring seat moves the steel wire. The steel wire acts as a force transmission medium, transferring the tension of the pull ring seat to the connecting pin and the limiting bracket, thereby controlling the limiting bracket. When it is necessary to replace the clamping seat, pulling the pull ring seat moves the limiting bracket via the steel wire, releasing the limitation on the clamping seat and facilitating its disassembly and replacement.

[0010] Preferably, a guide wheel is installed on the inner side of the bracket, and the guide wheel contacts the steel wire, guiding the movement of the steel wire. The main function of the guide wheel is to ensure that the steel wire always moves in the predetermined direction during movement, preventing the steel wire from deviating or tangling due to uneven force or other factors, thus ensuring the accuracy and stability of the operation. At the same time, the guide wheel can reduce the friction between the steel wire and the bracket, extending the service life of the steel wire and making the operation smoother.

[0011] Preferably, the stabilizing mechanism includes a screw, which is mounted inside the support frame via bearings. A threaded bracket is threadedly connected to the outside of the screw, and a support plate is fixedly connected to the lower end of the threaded bracket. A wheel frame is fixedly connected to the outside of the support frame, and wheels are mounted inside the wheel frame via bearings. The wheels facilitate the movement of the equipment box. The wheels enable the equipment box to move easily between different work sites, improving the mobility and flexibility of the laser marking robot and meeting the needs of different work scenarios. The screw, as the core component of the stabilizing mechanism, drives the threaded bracket to move up and down through rotation. The threaded connection between the threaded bracket and the screw enables the transmission and conversion of force, transforming the rotational motion of the screw into the linear motion of the threaded bracket. The support plate, driven by the threaded bracket, can rise or fall. When the equipment box moves to a designated position, adjusting the screw lowers the support plate until it contacts the ground, lifting the equipment box and causing the wheels to leave the ground, thereby improving the stability of the equipment box.

[0012] Preferably, the threaded frame is slidably connected to the support frame, and the support plate is in contact with the support frame. The threaded frame can drive the support plate to move. The sliding connection between the threaded frame and the support frame provides a track and guide for the linear movement of the threaded frame, ensuring that the threaded frame can move stably up and down under the drive of the screw. The contact between the support plate and the support frame, under the push of the threaded frame, can provide stable support for the equipment box, increase the contact area between the equipment box and the ground, and improve the stability of the equipment box.

[0013] Preferably, a motor is fixedly mounted on the upper end of the support frame, and the output shaft of the motor is fixedly connected to the screw. The motor can drive the screw to rotate. The motor provides the power source for the rotation of the screw. By controlling the forward and reverse rotation of the motor, the rotation direction and speed of the screw can be precisely adjusted, thereby realizing the raising or lowering of the threaded frame and the support plate. The automated control of the motor makes the stable adjustment of the equipment box more convenient and faster, improving work efficiency.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adds a limiting frame, connecting nails, and steel wires inside the equipment box. The limiting frame can be moved into the connecting plate below the clamping seat by the elastic force of a spring to limit the clamping seat. When replacement is needed, simply pull the pull ring seat. The pull ring seat moves the limiting frame through the steel wire and connecting nails. When the limiting frame is disengaged from the connecting plate, the limitation on the clamping seat can be released, so that the clamping seat can be easily disassembled for replacement.

[0016] 2. This utility model adds a screw, a threaded frame, and a support plate inside the support frame. After the equipment box is moved to the predetermined position by the wheels, the equipment box can be supported by the threaded engagement between the screw and the threaded frame, while the wheels are lifted off the ground, thus making the equipment box more stable.
