Description

Technical Field

[0001] This utility model belongs to the field of welding robot technology, and specifically relates to a welding robot protection device. Background Technology

[0002] Automated welding robots are emerging as a new product. From a technological standpoint, their automation level has reached a high level. Utilizing advanced programming systems and precise mechanical structures, they can accurately complete various welding operations according to preset programs, greatly reducing human intervention and effectively improving welding efficiency. Regarding weld quality, stable current and voltage control, along with precise welding path planning, results in highly consistent, aesthetically pleasing, and robust welds, significantly reducing product defect rates. More importantly, automated welding robots excel in dangerous scenarios such as those involving falls from heights or in toxic and hazardous environments (e.g., welding equipment near chemical plants or nuclear radiation areas) that pose serious health risks. They can operate reliably and continuously under adverse conditions, effectively ensuring the safety of workers and providing a reliable solution for welding tasks in special environments. Based on these significant advantages, automated welding robots have extremely broad application prospects in numerous industries such as automotive manufacturing, aerospace, and shipbuilding, becoming a key force driving the intelligent upgrading of the manufacturing industry.

[0003] However, existing automated welding robot technology has revealed some problems in actual operation. The environment in which robots move is often complex and changeable, with various obstacles appearing randomly. Currently, most automated welding robots lack sufficiently sensitive and efficient obstacle avoidance mechanisms, failing to detect and respond effectively to obstacles in a timely and accurate manner. Due to the lack of effective protective measures, once a collision occurs, critical components such as the robot's robotic arm and chassis are easily damaged, causing the robot to malfunction and interrupting the production process. This not only delays the project schedule but also requires significant investment of funds and time for equipment repair, greatly increasing the company's production costs and management complexity.

[0004] Therefore, providing a protective device for welding robots with obstacle avoidance and self-protection capabilities has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a welding robot protection device to at least solve some of the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A welding robot protection device is installed on the outside of a welding robot with a controller. It includes a support structure on the welding robot, a pressure sensor on the welding robot and connected to the controller, and a protective cover on the welding robot that can move towards the welding robot on the support structure after being pressed, and can abut against the pressure sensor after moving a certain distance.

[0008] Furthermore, the support structure includes several screws mounted on the welding robot, and the protective cover has through holes adapted to the screws, with the screws passing through the through holes; the screws are threaded with nuts to prevent the protective cover from slipping off the screws, and the screws are provided with a limiting mechanism to drive the protective cover away from the pressure sensor and abut against the nuts.

[0009] Furthermore, the limiting mechanism includes a spring that passes through the screw, with both ends of the spring in contact with the protective cover and the top of the welding robot, respectively.

[0010] Furthermore, the protective cover and the pressure sensor are positioned opposite each other, and the distance between the protective cover and the pressure sensor is less than the compression stroke of the spring.

[0011] Furthermore, a spring washer is installed on the screw, located between the spring and the welding robot, and the spring makes contact with the welding robot through the spring washer.

[0012] Furthermore, a washer is provided on the screw between the nut and the protective cover, and the nut contacts the top of the protective cover through the washer.

[0013] Furthermore, there are at least three screws.

[0014] Furthermore, there are four protective covers, which are arranged on the front, back, left, and right sides of the welding robot. Each protective cover is matched with a support structure and a pressure sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features a simple structure, scientific and reasonable design, and ease of use. When the welding robot encounters an obstacle during its movement, its front protective cover first contacts the obstacle and experiences pressure. At this moment, a pressure sensor mounted on the protective cover detects this change and quickly transmits a signal to the welding robot's controller. Upon receiving the instruction from the pressure sensor, the controller immediately commands the welding robot to pause its forward movement to avoid further collisions or damage. Subsequently, the welding robot's built-in navigation system initiates an obstacle avoidance program, using real-time environmental perception and data analysis to replan a safe and feasible route. This process not only effectively avoids obstacles but also ensures the welding robot's self-protection, thereby improving the safety and stability of equipment operation. Throughout the entire process, the coordinated work between the protective cover, pressure sensor, and controller plays a crucial role, ensuring the welding robot can successfully complete its tasks in complex environments.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] As attached Figure 1-5 As shown, this embodiment discloses a welding robot protection device, which is installed on the outside of a welding robot 8 with a controller 9. It includes a support structure on the welding robot 8, a pressure sensor 2 on the welding robot 8 and connected to the controller 9, and a protective cover 1 on the welding robot 8 that can move towards the welding robot 8 on the support structure after being pressed and can abut against the pressure sensor 2 after moving a certain distance.

[0027] This utility model is scientifically designed and ingeniously conceived. When the welding robot encounters an obstacle while moving, the protective cover is subjected to pressure. The pressure sensor sends a command, and the welding robot stops moving forward and replans its route, thereby achieving obstacle avoidance and self-protection.

[0030] The support structure includes several screws 5 mounted on the welding robot 8. The protective cover 1 has through holes 10 adapted to the screws 5, and the screws 5 pass through the through holes 10.

A nut 6 is threaded onto the screw 5 to prevent the protective cover 1 from slipping off the screw 5. A limiting mechanism is provided on the screw 5 to drive the protective cover 1 away from the pressure sensor 2 and abut against the nut 6. In this embodiment, the support structure supports the protective cover and prevents it from slipping.

Specifically, the limiting mechanism includes a spring 3 passing through the screw 5, with both ends of the spring 3 in contact with the protective cover 1 and the welding robot 8, respectively. When the welding robot encounters an obstacle during its movement, the protective cover is subjected to pressure, compressing the spring and causing it to inwardly contact the pressure sensor. After receiving pressure, the pressure sensor issues a command, causing the welding robot to stop moving forward and replan its route.
