[0015] Preferably, the composite filter material block is composed of an activated carbon fiber layer, a glass fiber filter layer and a ceramic fiber layer stacked sequentially, and the layers are fixedly connected by an adhesive.

[0016] The present invention has the following beneficial effects:

[0017] I. Reduced Smoke and Dust Pollution and Improved Working Environment: This invention features welding robots mounted on both sides of a frame. A filter box is located below the auxiliary rollers on the frame. The top of the filter box is connected to a main collection pipe, which in turn connects to multiple branch collection pipes. The air inlets of each branch collection pipe are located between the gaps of the two auxiliary rollers and arranged in a rectangular array. This design allows for the timely collection of smoke and dust generated during welding. The smoke and dust enters the main collection pipe through the branch collection pipes and then into the filter box. The filter box is filled with composite filter material blocks, which effectively filters the smoke and dust, reducing pollution to the working environment and preventing harm to the health of operators. Simultaneously, multiple branch exhaust pipes are connected to the bottom of the main exhaust pipe, and both the main collection pipe and the main exhaust pipe are equipped with pressure pumps, ensuring the power for smoke and dust collection and filtration, and improving smoke and dust treatment efficiency.

[0018] II. Ensuring the Normal Operation of Welding Equipment and Improving Welding Quality and Production Efficiency: Fumes not only pollute the working environment but can also interfere with the normal operation of welding equipment, thus affecting the welding quality and production efficiency of automotive seats. This invention utilizes an effective fume collection and filtration system to promptly treat welding fumes, reducing their adhesion and impact on the welding equipment, ensuring its normal operation, and thereby improving the welding quality and production efficiency of automotive seats.

[0019] III. Condensation and Gas Circulation System: The condenser's outlet is connected to a return gas pipe. A gas-gathering chamber is located at the top of the casing, with its top sidewall connected to the return gas pipe. A small air pump is installed on the return gas pipe, and a guide impeller is installed inside the gas-gathering chamber. A flow equalization plate and a gas-gathering hood are installed at the bottom. After filtration and condensation, the gas is drawn back to the gas-gathering chamber by the small air pump. The guide impeller ensures even gas distribution, the flow equalization plate further guarantees uniform gas flow, and the gas-gathering hood guides the gas directly above the frame, forming a certain gas circulation. This helps improve the air environment around the frame, further reducing the impact of fumes on the welding area. Simultaneously, this circulation system also helps maintain temperature stability in the welding area, positively impacting welding quality.

[0020] IV. Electric Lifting Doors for Material Inlet and Outlet: Electric lifting doors are installed at the material inlet and outlet. They can be closed during welding operations to prevent external dust from entering the housing, maintain a clean environment inside the housing, and reduce interference from external factors on the welding process. When material needs to be loaded or unloaded, the electric lifting doors can be opened quickly for convenient operation, improving the convenience and efficiency of production.

[0021] V. Shell Observation Windows and Support Blocks: Multiple observation windows are provided on the shell to allow operators to observe the internal welding process without opening the shell, keep track of the welding progress and equipment operating status, and facilitate timely handling of any problems that may arise. Support blocks are fixed at the four corners of the bottom of the shell to provide stable support for the entire device, ensuring the stability of the device during operation and improving welding accuracy.

[0022] VI. Six-axis robotic arm and high-temperature resistant protective coating: The robotic arm is a six-axis robotic arm, with each axis equipped with an independent drive motor that is connected to the respective axes of the robotic arm. This allows for precise control of the robotic arm's movement trajectory and posture, meeting the welding requirements of complex automotive seat structures and improving welding accuracy and flexibility. The surface of the robotic arm is coated with a high-temperature resistant protective coating, which prevents damage to the robotic arm caused by the high temperatures generated during the welding process, extends the service life of the robotic arm, and reduces equipment maintenance costs.

[0023] 7. Pneumatic gripper anti-slip rubber pad: The pneumatic gripper is equipped with an anti-slip rubber pad on the inside, and the surface of the anti-slip rubber pad has a wavy texture, which increases the friction between the pneumatic gripper and the car seat parts. During the clamping process, the parts can be more firmly fixed, preventing the parts from sliding during the welding process, ensuring the accuracy of the welding position, and improving the welding quality.

[0024] 8. Replaceable welding torch: The welding torch mounted on the welding arm of the welding robot has a replaceable torch head. According to different welding requirements and welding materials, the appropriate torch head can be replaced, which improves the applicability of the device and can meet the requirements of various automotive seat welding processes.

[0025] 9. Filter Box with Multiple Filtration Chambers and Composite Filter Material Blocks: The filter box is designed as a cuboid, divided into multiple filtration chambers by horizontally placed partitions. Multiple flow holes are evenly distributed on the partitions, and composite filter material blocks are placed in each of these chambers. This design increases the filtration path and area of ​​the smoke and dust within the filter box, improving the filtration effect. The composite filter material blocks are composed of layers of activated carbon fiber, glass fiber mesh, and ceramic fiber, stacked sequentially and fixed together with adhesives. Different layers of filter material can filter smoke and dust of different particle sizes and properties, achieving multi-stage filtration and further improving the filtration precision and purification effect.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 3As shown, a robotic welding-based automotive seat welding production apparatus includes a frame 1. Two robotic arms 201 are mounted on each side of the frame 1, with pneumatic grippers 202 connected to the ends of the robotic arms 201. Multiple auxiliary rollers 3, rotatably connected to the frame 1, are mounted on top of the frame 1 and distributed along its length. Welding robots 4 are mounted on both sides of the frame 1. A filter box 601 is mounted below the auxiliary rollers 3 on the frame 1. A main collection pipe 602 is connected to the top of the filter box 601, and multiple collection branch pipes 603 are connected to the top of the main collection pipe 602. The air inlet of 603 is located between the gaps of the two auxiliary rollers 3, and the air inlets of each collection branch pipe 603 are arranged in a rectangular array; the filter box 601 is filled with composite filter material blocks 604, the bottom of the filter box 601 is connected to the main air outlet pipe 605, the bottom of the main air outlet pipe 605 is connected to multiple air outlet branch pipes 606, and both the main collection pipe 602 and the main air outlet pipe 605 are equipped with a pressure pump 607; a housing 8 is provided outside the frame 1, the frame 1 is fixedly installed at the bottom of the housing 8, the air outlet branch pipe 606 extends out of the housing 8 and is connected to a condenser 608, and an inlet and outlet port is opened on one side of the housing 8.

[0034] like Figures 1 to 3 As shown, the automotive seat components to be welded are placed on multiple auxiliary rollers 3 above the frame 1. Since the auxiliary rollers 3 are rotatably connected to the frame 1 and distributed along its length, the components can be transported on the frame 1 by the rotation of the auxiliary rollers 3, facilitating their movement to the designated welding position. Pneumatic grippers 202 are connected to the ends of two robotic arms 201 on both sides of the frame 1. When the component is transported to the appropriate position, the pneumatic grippers 202 close under the drive of the pneumatic system, clamping and fixing the component, providing stable support for subsequent welding operations and preventing the component from moving during welding and affecting the welding quality. The welding robots 4 positioned on both sides of the frame 1 begin operation. Their welding arms move according to a preset program and trajectory, and the welding torch is aimed at the component fixed by the pneumatic grippers 202 to perform the welding operation, completing the welding of the automotive seat components.

[0035] A large amount of fumes are generated during the welding process. The air inlets of each collection branch pipe 603 are located between the gaps of the two auxiliary rollers 3 and arranged in a rectangular array. This layout can cover the welding area to the maximum extent, so that the generated fumes can be drawn into the collection branch pipe 603 in a timely manner. The collection branch pipe 603 collects the fumes into the collection main pipe 602, and the collection main pipe 602 then transports the fumes into the filter box 601. The filter box 601 is filled with composite filter material blocks 604. When the fumes enter the filter box 601, they pass through the composite filter material blocks 604. The composite filter material blocks 604 are composed of multiple layers of filter materials of different materials, which can intercept and adsorb particles of different sizes and properties in the fumes, thereby achieving the filtration and purification of the fumes and ensuring that the emitted gas meets environmental protection requirements. The filtered gas passes through the exhaust main pipe 605 at the bottom of the filter box 601, and then exits the shell 8 through multiple exhaust branch pipes 606 at the bottom of the exhaust main pipe 605 and enters the condenser 608. The condenser 608 cools the gas, reducing its temperature. A portion of the cooled gas may return to the casing 8 through a specific pipe to maintain a suitable temperature and gas environment within the casing 8, reducing the impact of external factors on the welding process; the other portion is discharged into the external environment.

[0036] The outer casing 8 of the frame 1 encloses the entire welding area, providing protection and reducing the entry of external dust and other impurities. It also reduces the impact of noise and light radiation generated during welding on the surrounding environment. The inlet and outlet ports on one side of the casing 8 are used for inserting automotive seat parts and removing them after welding.

[0037] like Figures 1 to 3 As shown, the outlet end of the condenser 608 is connected to a return pipe 609. A gas-gathering chamber 701 is provided on the top of the housing 8. The top side wall of the gas-gathering chamber 701 is connected to the return pipe 609. A small air pump 610 is provided on the return pipe 609. A guide impeller 702 is provided inside the gas-gathering chamber 701. A flow equalization plate 703 is provided at the bottom of the gas-gathering chamber 701. A gas-gathering hood 704 is fixedly provided at the bottom edge of the gas-gathering chamber 701. The gas-gathering hood 704 is located directly above the frame 1.

[0038] After being cooled by the condenser 608, the gas enters the return pipe 609 through the outlet. A small air pump 610 on the return pipe 609 starts, pressurizing the gas and delivering it to the gas-gathering chamber 701 at the top of the housing 8. The guide impeller 702 inside the gas-gathering chamber 701 begins to rotate under the influence of the airflow. The rotation of the guide impeller 702 guides and agitates the gas entering the gas-gathering chamber 701, ensuring a uniform gas distribution within it. A flow equalization plate 703 is located at the bottom of the gas-gathering chamber 701, further equalizing the gas flow and allowing it to pass through the gas-gathering hood 704 at a more uniform speed and direction. The gas-gathering hood 704 is located directly above the frame 1. The equalized gas is evenly blown downwards from the gas-gathering hood 704 onto the frame 1, providing a relatively stable and clean airflow environment for the welding area, reducing the entry of external impurities into the welding area, and simultaneously cooling the welding area to a certain extent, thus improving welding quality.

[0039] like Figures 1 to 3 As shown, an electric lifting door 801 is provided at the inlet and outlet. When it is necessary to put in or take out automotive seat parts, the electric lifting door 801 rises under the drive of the motor, opening the inlet and outlet to facilitate the entry and exit of the parts; after the loading and unloading operation is completed, the electric lifting door 801 closes downward, sealing the inlet and outlet, so that the housing 8 re-forms a relatively closed space, maintaining a stable gas environment and protective effect inside the housing 8.

[0040] like Figures 1 to 3 As shown, the support blocks 802 fixed at the four corners of the bottom of the housing 8 serve to support the entire device, ensuring its stable placement on the ground and preventing swaying or tilting due to uneven ground or uneven weight distribution, thus guaranteeing the stability of the device during operation. Multiple observation windows 803 on the housing 8 allow technicians to directly observe the welding process of the car seat inside the housing 8, the transport of components, and the working status of each piece of equipment without opening the housing 8, facilitating timely detection and handling of potential problems.

[0041] like Figures 1 to 3As shown, the robotic arm 201 adopts a six-axis structure, which offers high flexibility and freedom, capable of simulating various movements of a human arm. Each robotic arm 201 is equipped with an independent drive motor, connected to each axis of the robotic arm 201. By controlling the speed, direction, and rotation angle of the drive motors, the movement of each axis of the robotic arm 201 can be precisely controlled, thereby precisely controlling the overall movement trajectory and posture of the robotic arm 201. This allows the robotic arm 201 to accurately move the pneumatic gripper 202 to a designated position, completing the gripping and placement operation of the car seat component. The high-temperature resistant protective coating on the surface of the robotic arm 201 effectively blocks the high-temperature radiation and spatter generated during welding, protecting the internal drive motor and transmission components from high-temperature damage and extending the service life of the robotic arm 201.

[0042] like Figures 1 to 3 As shown, the anti-slip rubber pad on the inner side of the pneumatic gripper 202 increases the friction between the gripper and the component when the pneumatic gripper 202 clamps the automotive seat component, preventing the component from slipping or falling off during clamping. The wavy texture on the surface of the anti-slip rubber pad further increases the coefficient of friction of the contact surface with the component, improving the anti-slip effect and ensuring that the pneumatic gripper 202 can stably and reliably clamp the component, providing stable support for subsequent welding operations.

[0043] like Figures 1 to 3 As shown, welding robot 4 is an arc welding robot, and the welding torch mounted on its welding arm is a key component for welding operations. During the welding process, the arc welding robot controls the welding arm to move the welding torch to the designated welding position according to preset programs and parameters. The welding torch generates an electric arc, melting the welding wire and filling it into the welding joint of the automotive seat component, thus achieving welding. The welding torch tip is replaceable; different specifications and models of torch tips can be used depending on the welding materials, welding processes, and welding requirements to adapt to various welding scenarios, improving welding quality and flexibility.

[0044] like Figure 4As shown, the filter box 601 is a cuboid, divided into multiple filter chambers by horizontally placed partitions 611. This structure allows the gas or liquid to be filtered to form a multi-stage filtration path within the filter box 601. When the gas or liquid enters from the inlet of the filter box 601, it flows through each filter chamber sequentially. Multiple evenly spaced flow holes on the partitions 611 allow the gas or liquid to flow between adjacent filter chambers, while also dispersing the fluid to a certain extent, enabling the fluid to contact the composite filter material blocks 604 in each filter chamber more evenly, thus improving the filtration effect. An inspection door 612 is provided on the side wall of the filter box 601, allowing technicians to easily open the door when needed to inspect, replace, or clean the composite filter material blocks 604 inside the filter box 601. When the composite filter material block 604 reaches the end of its service life or the filtration effect decreases, technicians can open the inspection door 612, remove the old composite filter material block 604, and replace it with a new composite filter material block 604 to ensure that the filtration performance of the filter box 601 is always in good condition.

[0045] like Figure 4 As shown, the composite filter material block 604 is composed of an activated carbon fiber layer, a glass fiber filter layer, and a ceramic fiber layer stacked sequentially. The activated carbon fiber layer has a large number of microporous structures, possessing strong adsorption capacity, effectively adsorbing organic pollutants, odor molecules, and other impurities from gases or liquids. The glass fiber filter layer has good filtration precision, intercepting and filtering out larger particles of dust and impurities. The ceramic fiber layer has high temperature resistance and corrosion resistance, while also filtering and blocking some small particles and harmful substances. The layers are fixedly connected by an adhesive, ensuring the structural stability of the composite filter material block 604 and enabling the layers to work synergistically to achieve multi-stage, high-efficiency filtration of gases or liquids.

[0046] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
