[0024] Please refer to Figs. 1-3The utility model provides a kind of early warning buffer platform for welding robot teaching uses, including upper cover plate 1, lower bottom plate 2, spring 3, tilt switch 4 and alarm device 5, upper cover plate 1 and lower bottom plate 2 are the wooden flat plate of 15 millimeters thick, wooden material has certain toughness and buffering performance, and cost is lower, is suitable for teaching use scene.Upper cover plate 1 is arranged above lower bottom plate 2, and upper cover plate 1 and lower bottom plate 2 are connected by multiple springs 3, utilize the deformation ability of spring 3, prevent serious damage when welding torch collides simulation workpiece, in the embodiment, the top surface of upper cover plate 1 is rectangular structure, spring 3 is set four, and is respectively arranged at the four corners of upper cover plate 1.Tilt switch 4 is arranged on upper cover plate 1, tilt switch 4 is electrically connected alarm device 5 for controlling its switch, the present application adopts 5 volts switch power supply.Through the synergistic effect of buffering and early warning function, student can be reminded to stop the operation of welding robot in time, and corresponding adjustment measures are taken, unnecessary start of robot body anti-collision alarm is avoided, the personal safety of student in the operation process and the safety of teaching equipment are fundamentally guaranteed, and solid guarantee is provided for the smooth development of welding robot teaching activity.

[0025] Upper cover plate 1 bottom and lower bottom plate 2 top surface symmetrically are provided with multiple support columns 6, and the two ends of each spring 3 are respectively sleeved on the opposite two support columns 6.Spring 3 is 21mm in diameter, 80mm in height, and 1.5mm in steel wire diameter.

[0026] Support column 6 is nylon rod, and nylon rod and upper cover plate 1 are connected by screw, as shown in Fig. 3 Sunk hole 8 is opened in the corner of upper cover plate, and nylon rod and upper cover plate 1 are connected and fixed by screw from sunk hole 8.Nylon rod is used as support, which can support and guide compression spring 3, ensure the stability of spring 3 in compression and rebound process, and further enhance the reliability of buffer platform.

[0027] Elastic protective layer 7 is connected between the outer side of upper cover plate 1 and the outer side of lower bottom plate 2, and accordion soft rubber is preferably used for connection.This design not only can effectively prevent foreign matters from entering the inside of platform, affect the normal work of spring 3 and other components, but also accordion soft rubber has good flexibility, will not limit the up-down and left-right displacement of platform when being collided, and can also play the role of auxiliary buffering collision force to a certain extent.

[0028] The tilt switch 4 is a mercury trigger switch, which is provided with two, one of which is installed horizontally, and the other is installed vertically, to ensure that the tilt switch 4 can be triggered from any angle. When the platform is displaced in any direction due to the collision of the welding gun with the simulated workpiece, the mercury inside the mercury trigger switch will flow due to the inertia of displacement, thereby triggering the conduction of the circuit, activating the alarm circuit, and making the alarm device 5 work, thereby issuing a warning to give students valuable reaction time and avoid further expansion of the accident. When the welding robot collides and is eliminated, the platform returns to its original position, the mercury in the mercury trigger switch returns to its original position, the circuit is disconnected, and the alarm device 5 stops alarming. The alarm device 5 is a buzzer, which can emit loud buzzing sound, has the characteristics of high sensitivity and loud sound, and can attract the attention of students in time when triggered, thereby playing a reminding role.

[0029] Moreover, the alarm sound of the present application can be automatically stopped with the elimination of the collision, without manual intervention, thereby realizing the automatic control of the entire warning system. This not only improves the convenience of using the equipment, but also reduces the mistakes that may be caused by manual operation, thereby making the teaching process more smooth and efficient.

[0030] After the installation is completed, power-on debugging is required. First, check whether the output voltage of the 5-volt switching power supply is stable at 5 volts, and adjust or replace the power supply in time if there is deviation. Then, simulate the up-down-left-right displacement of the platform by hand, and observe whether the two mercury trigger switches can accurately trigger the alarm circuit and whether the active buzzer can normally emit loud buzzing sound. At the same time, check whether the alarm buzzer can automatically stop sounding when the simulated displacement stops and the platform returns to its original position. If there is an abnormal situation, carefully check the circuit connection and component performance, and troubleshoot and repair the problems one by one until the warning trigger circuit and the alarm device 5 can work normally and stably.

[0031] Method of use:

[0032] 1. Place the assembled warning buffer platform on the working platform of the teaching welding robot, fix it using the standard clamps provided on the working platform, and ensure that the platform is placed stably and will not shake or displace.

[0033] 2. The student starts to operate the welding robot to program and weld the simulated workpiece. During the operation, due to the inexperience of the student or other reasons, when the welding gun of the welding robot accidentally touches the simulated workpiece, the buffer platform will immediately displace in the up-down-left-right direction.

[0034] 3. The displacement of the platform will cause the mercury inside the mercury trigger switch installed on the upper cover plate 1 to flow, thereby triggering the alarm circuit, and the active buzzer will immediately emit loud buzzing sound to remind the student to immediately stop operating the welding robot.

[0035] 4. After hearing the alarm, the student stops the welding robot immediately, checks the posture and position of the welding torch carefully, analyzes the collision reason, and adjusts the program or operation of the welding robot accordingly. After confirming that the adjustment is correct, the student can continue the operation practice.

[0036] 5. After each teaching activity, the anti-collision warning buffer platform should be checked and maintained comprehensively. Check the mechanical structure of the platform, including whether the wooden platform has cracks or damage, whether the spring is normal, whether the nylon support is loose, whether the accordion soft rubber is damaged or delaminated, etc. Check the warning trigger circuit and alarm device, including whether the 5-volt switching power supply is working normally, whether the soft wire is damaged or broken, whether the active buzzer can sound normally, whether the mercury trigger switch is sensitive, etc. If problems are found, repair or replace the relevant parts in time to ensure that the anti-collision warning buffer platform can run normally in the next teaching activity and continue to provide reliable protection for teaching safety.

[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
