Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a robotic welding workstation with protective functions. Background Technology

[0002] In the field of machining, it is often necessary to weld many workpieces. Traditional manual welding methods, due to their low efficiency, poor stability, and unsuitability for assembly line production, have been replaced by robotic welding workstations. Robotic welding workstations are widely used in applications involving large workpieces, numerous and long weld seams, high welding requirements, and significant technical challenges.

[0003] Welding robots typically generate harmful gases during operation, and these gases are usually left to float directly in the workshop, posing a hazard to workers.

[0004] Therefore, we propose a robotic welding workstation with protective functions to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a robotic welding workstation with protective function, comprising a base plate and a welding table mounted on the top of the base plate. An exhaust fan is installed inside the welding table, and the exhaust end of the exhaust fan is connected to an exhaust box mounted on the upper part of the welding table via an exhaust pipe. The exhaust box has several exhaust ports extending to the outside of the welding table, which are used to extract harmful gases generated during welding. The exhaust outlet of the exhaust fan is connected to a filter device via an exhaust pipe, which is used to filter the harmful gases.

[0007] Furthermore: the gas filtration device includes a filter box; an air inlet sealed to an exhaust pipe is installed at the upper part of the filter box; a filter element for filtering harmful gases is installed inside the filter box; an air outlet for discharging gases is installed at the lower part of the filter box, and an exhaust pipe extending to the outside of the welding station is sealed to the air outlet.

[0008] Furthermore: the interior of the exhaust box is fixed with several parallel partitions at equal intervals, and the partitions divide the exhaust fan into several chambers. The multiple exhaust ports are connected to the interior of the chambers. The bottom of each of the chambers is provided with several air inlets. The air inlets at both ends are sealed with the same "U"-shaped pipe. The outer surface of the "U"-shaped pipe is fixed with several connecting pipes, and the multiple connecting pipes are connected to the remaining air inlets. Solenoid valves are installed at both ends of the "U"-shaped pipe and on the multiple connecting pipes. The center of the "U"-shaped pipe is sealed to the end of the exhaust pipe.

[0009] Furthermore, several pillars are fixed at the corners of the top of the substrate, and protective railings can be detachably installed between adjacent pillars.

[0010] Furthermore: the top of the column is fixed with a downward recessed notch, and the upper part of both sides of the guardrail is provided with a locking block that cooperates with the notch.

[0011] Furthermore, a mounting base is also installed on the top of the substrate, and the mounting base is located on the front side of the welding station. A robot for welding workpieces is mounted on the mounting base.

[0012] The beneficial effects of this utility model are:

[0013] This invention includes an exhaust fan, an exhaust pipe, and an exhaust box installed inside the welding station. Through the cooperation of the exhaust fan and the exhaust pipe, the gas inside the exhaust box can be extracted, creating a negative pressure inside the exhaust box and extracting harmful gases from the workshop. This allows for the extraction of harmful gases generated during welding, preventing them from floating in the air and reducing the harm to workers.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] Example 1

[0025] A robotic welding workstation with protective functions includes a base plate 1. A welding table 2 and a mounting base 13 are respectively mounted on the top of the base plate 1, and the mounting base 13 is located on the front side of the welding table 2. A welding robot (not shown in the figure) is mounted on the mounting base 13. The welding robot can weld workpieces. A clamp (not shown in the figure) is usually mounted on the inclined surface of the welding table 2. The clamp can hold the workpiece, so that the workpiece can be welded stably, improving the practical effect of the device.

[0026] An exhaust fan 3 is installed at the bottom inside the welding station 2, and the exhaust port of the exhaust fan 3 is connected to the exhaust box 5 through the exhaust pipe 4. Several exhaust ports 6 are fixed at equal intervals on the side of the exhaust box 5, and the exhaust ports 6 extend to the outside of the welding station 2. Through the exhaust fan 3 and the exhaust pipe 4, air can be drawn from the inside of the exhaust box 5 to form a negative pressure. The several exhaust ports 6 can extract the harmful gases generated during welding, reducing the harm caused to workers by the harmful gases floating in the workshop. An exhaust pipe 7 is installed at the air outlet of the exhaust fan 3, and one end of the exhaust pipe 7 is connected to a filter device. The extracted harmful gases can be transported to the inside of the filter device through the exhaust pipe 7, thereby filtering the harmful gases and reducing the harm caused to workers. It should be noted that the filter device can be installed inside or outside the welding station 2, which can be selected according to the user's needs.

[0027] In detail: The interior of the exhaust box 5 has several parallel partitions 501 fixed at equal intervals, dividing the interior of the exhaust box 5 into several chambers 502. Each chamber 502 is connected to an exhaust port 6, allowing exhaust and extraction of harmful gases from each chamber 502. It should be noted that each chamber 502 has an air inlet 503 at its bottom, and the same U-shaped pipe 504 is sealed and connected to the air inlets 503 at both ends. The outer surface of the U-shaped pipe 504 is fixed with… Several upward-facing connecting pipes 505 are provided. It should be noted that multiple connecting pipes 505 are connected to the remaining air inlets 503 respectively. Each connecting pipe 505 and both ends of the "U"-shaped pipe 504 are equipped with solenoid valves (not shown in the figure), so that each area can be individually controlled and ventilated. This allows for adjustment according to the welding position, improving the effectiveness of the device. The center of the outer surface of the "U"-shaped pipe 504 is sealed to the exhaust pipe 4, thereby enabling the extraction of gas from the exhaust box 5.

[0028] In detail: The gas filtration device includes a filter box 801; the filter box 801 can be installed inside or outside the welding station 2. An air inlet 802 is installed on the upper part of the filter box 801, and the air inlet 802 is sealed to the exhaust port of the exhaust pipe 7. Through the setting of the air inlet 802, the extracted harmful gas can be transported into the interior of the filter box 801; a filter element 803 is installed inside the filter box 801. Through the setting of the filter element 803, the harmful gas can be filtered, thus treating the harmful gas; an air outlet 804 is installed at the lower part of the filter box 801, and an air outlet pipe 805 is installed on the air outlet 804. Through the setting of the air outlet pipe 805, the treated gas is discharged.

[0029] During the welding process: the exhaust fan 3 can be turned on, and the exhaust fan 3 can draw air from the exhaust pipe 4. The exhaust pipe 4, through the "U" shaped pipe 504 and several connecting pipes 505, can draw the gas inside the chamber 502. Due to the negative pressure generated inside the chamber 502, harmful gases are drawn into the chamber 502 through the exhaust port 6, thereby filtering the harmful gases and reducing the harm caused to workers by the harmful gases floating in the workshop. The extracted gas can be transported to the filter box 801 through the exhaust pipe 7. The harmful gases are filtered by the filter element 803 in the filter box 801, and the filtered gas is discharged through the exhaust pipe 805.

[0030] During the welding process: If air needs to be extracted from a localized area, only the corresponding solenoid valve can be opened, while the rest of the solenoid valves remain closed. During the extraction process, air can only be extracted from the chamber corresponding to the open solenoid valve, thus allowing the extraction of gas from the corresponding location. This can be selected according to the user's needs.

[0031] Example 2

[0032] Although the above-described embodiment one can treat harmful gases, during the robotic welding process, some workers inevitably come close to the working welding robot, posing a certain danger. Therefore, in order to overcome the aforementioned technical defects, improvements are made based on the above-described embodiment one:

[0033] Several columns 9 are fixed at the corners of the base plate 1. A protective railing 10 is detachably installed between adjacent columns 9. The protective railing 10 serves to protect against workers from getting too close to the welding robot during operation, thereby reducing safety hazards.

[0034] In detail: The top of the column 9 has a notch 11, and each guardrail 10 has a locking block 12 fixed on both sides of the upper part. During the installation of the guardrail 10, the locking block 12 can be inserted into the notch 11 for easy disassembly and to provide convenience for the staff.
