Description

Technical Field

[0001] This utility model relates to the field of welding fume treatment technology, and more specifically to a welding fume treatment device. Background Technology

[0002] Welding fume treatment is a systematic engineering technology that captures, separates, and purifies the fumes, harmful gases, and gaseous pollutants generated during welding operations, thereby improving the working environment, protecting personnel health, and meeting environmental emission requirements.

[0003] According to patent publication number CN220758397U, published on April 12, 2024, a welding fume treatment device is disclosed, including an intake pipe, an intake hood at one end of the intake pipe, a fan inside the intake hood, a treatment cylinder at the other end of the intake pipe, a connecting pipe on the other side of the treatment cylinder, an exhaust pipe on the connecting pipe, a limiting cylinder inside the treatment cylinder, a purification layer inside the limiting cylinder, and a replacement assembly inside the treatment cylinder for replacing the limiting cylinder. The replacement assembly includes a maintenance port, a sliding member, a sealing member, a spring, and a drive assembly. The maintenance port is located at the top of the treatment cylinder. The sliding member is slidably disposed inside the treatment cylinder. The sealing member is disposed on one side of the sliding member, with one end extending into the maintenance port. The two ends of the spring are fixedly connected to the sliding member and the treatment cylinder, respectively. The drive assembly is connected to the sliding member.

[0004] In the aforementioned patents, the extraction and filtration of welding fumes is achieved through the combination of an air suction pipe and an air suction hood with a purification layer in the treatment cylinder. However, in actual use, the air suction hood is often located above the welding equipment, which can easily obstruct the view and affect the actual welding operation. In addition, some air suction pipes are fixedly installed, requiring the operator to move the circuit board to be welded closer to the air suction pipe to achieve an effective extraction of fumes, which is inconvenient for actual welding operations. Utility Model Content

[0005] The purpose of this invention is to provide a welding fume treatment device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding fume treatment device, including a suction pipe connected to a suction device, a suction platform fixedly installed at one end of the suction pipe, and a placement groove opened on the top of the suction platform, and a suction port opened on the inner wall of one side of the placement groove to connect the suction pipe and the placement groove.

[0007] Preferably, the top of the suction platform is provided with a boss, and an air cavity communicating with the placement slot is opened in the boss, and a centrifugal fan is axially rotatably installed in the air cavity.

[0008] Preferably, a baffle plate is fixedly installed on the inner wall of the air cavity.

[0009] Preferably, a lamp plate is fixedly installed on the outer wall of the boss located on one side of the placement groove.

[0010] Preferably, the suction tube is symmetrically fixed and connected to a secondary tube.

[0011] Preferably, the device includes a tilting frame, and the conical cover at the end of the secondary tube is movably mounted on a stop block fixedly installed on the tilting frame.

The outer wall of the stop block is provided with an installation groove, and the inner wall of the installation groove is provided with a narrow groove. The protruding edge provided at the end of the conical cover is movably disposed in the narrow groove, and a sealing rubber pad is fixedly installed on the inner wall of the narrow groove.

[0013] Preferably, the suction platform has swing rods hinged in the side grooves symmetrically opened on the outer walls on both sides, and the flipping frame is set on the swing rods. The secondary tube passes through the side plate fixedly installed on the flipping frame.

[0014] Preferably, the tilting frame is slidably mounted on the swing arm.

[0015] Preferably, the suction platform is an aluminum alloy platform.

[0016] In the above technical solution, the welding fume treatment equipment provided by this utility model has the following beneficial effects: by integrating the suction port into the side wall of the placement slot of the suction platform, and cooperating with the suction pipe, the fume capture point is located near the workpiece placement plane, rather than the traditional high-level suction hood. This design avoids the vertical obstruction of the welding operation area by the equipment, so that the operator's line of sight is not disturbed, improving welding accuracy and safety. The operator can directly place the workpiece in the placement slot for welding without frequently moving the workpiece or adjusting the equipment position. The structural design of the placement slot allows the fume to accumulate in a limited space and directly enter the suction pipe through the side wall suction port.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 The present invention provides a technical solution, including the following embodiments: Example

[0022] like Figure 1 As shown, this embodiment describes the basic structure and working principle of the welding fume treatment equipment.

[0023] Specifically, the device includes a suction platform 1 and a suction pipe 2. One end of the suction pipe 2 is connected to an external suction device, such as a fan or filtration system, and the other end is fixedly installed on the suction platform 1. A placement groove 11 is provided on the top of the suction platform 1 for directly placing the welding workpiece. A suction port 12 is provided on the inner wall of one side of the placement groove 11, so that the suction pipe 2 communicates with the inside of the placement groove 11.

[0024] By integrating the suction port 12 into the side wall of the placement slot 11, the fume capture point is located near the workpiece placement plane, rather than in a traditional high-level suction hood. This design avoids vertical obstruction of the welding operation area by the equipment, ensuring uninterrupted operator visibility and significantly improving welding accuracy and safety. Operators can directly place the workpiece in the placement slot 11 for welding without frequently moving the workpiece or adjusting the equipment position, reducing operator fatigue and wasted time. The recessed structure of the placement slot 11 allows fumes to naturally accumulate within a limited space and be directly and directionally drawn into the suction pipe 2 through the side wall suction port 12. Compared to the traditional top suction mode, this side suction method reduces fume loss during diffusion, effectively lowers the risk of hazardous substance leakage, and improves the hygiene of the working environment. Furthermore, the suction table 1 is made of aluminum alloy, which is lightweight and can dissipate heat during the welding of circuit boards with metal bottoms. The top of the suction platform 1 is also provided with an integrated boss 14, and an air cavity 13 is opened in the boss 14. The air cavity 13 is connected to the placement groove 11. A centrifugal fan 4 is installed in the air cavity 13 to enhance the guidance of local airflow. A baffle plate (41) is fixedly installed on the inner wall of the air cavity (13) so that the centrifugal fan 4 blows air along the inner wall of the placement groove 11 and drives the flue gas to the suction port 12, thereby guiding the airflow. Example

[0025] like Figure 2 As shown, this embodiment introduces a secondary tube 21 and an adjustable suction point structure to expand the device's functionality.

[0026] Specifically, the suction pipe 2 is symmetrically and fixedly connected to a secondary pipe 21, and a stainless steel conical cover 22 is fixed to the end of the secondary pipe 21. A swing rod 3 is hinged to each of the symmetrically opened side grooves 15 on opposite sides of the suction table 1. A tilting frame 31 is mounted on the swing rod 3, and the secondary pipe 21 passes through a side plate 33 fixedly installed on the tilting frame 31. The tilting frame 31 is slidably mounted on the swing rod 3 and can rotate around the hinge point, allowing the position of the conical cover 22 to be adjusted. By sliding the tilting frame 31, the operator can expand the hole. When the end of the conical cover 22 disengages from the stop block 32, the conical cover 22 can perform suction. Therefore, when it is necessary to expand the suction range, the conical cover 22 of the secondary pipe 21 is used for auxiliary suction; when only the workpiece in the placement groove 11 needs to be processed, the conical cover 22 can be closed, and suction is only performed through the suction port 12, thereby increasing the suction intensity in the placement groove 11 area. This method improves equipment flexibility, reduces equipment space requirements, and avoids the limitations of fixed installation through an adjustable structure.

[0027] Furthermore, a light panel 5 is fixedly installed on the outer wall of the boss 14 on one side of the placement groove 11 to provide local lighting, compensate for insufficient light during welding, and further enhance operational safety. Example

[0028] like Figure 4 As shown, this embodiment optimizes the fixing and sealing structure of the conical cover 22 to ensure suction efficiency and prevent leakage.

[0029] Specifically, the top of the stop block 32 has a U-shaped groove 34, and a flexible rubber pad 35 is fixedly installed inside the U-shaped groove 34. The outer wall of the stop block 32 has an installation groove 36, and the inner wall of the installation groove 36 has a narrow groove 37. The protruding edge 23 at the end of the conical cover 22 is movably disposed within the narrow groove 37, and a sealing rubber pad 38 is fixedly installed on the inner wall of the narrow groove 37. Therefore, the U-shaped groove 34, together with the flexible rubber pad 35, forms an elastic snap-fit ​​structure, facilitating quick installation or removal of the secondary pipe 21, while also buffering vibration and noise. The matching design of the protruding edge 23 and the narrow groove 37 allows the conical cover 22 to be movably disposed on the stop block 32, facilitating flexible switching when opening or closing the secondary pipe 21. The sealing rubber pad 38 ensures airtightness at the connection. This method simplifies the maintenance process, allowing operators to adjust the conical cover 22 without tools; the secondary pipe 21 can be made of high-temperature resistant rubber hose. Example

[0030] like Figure 3 As shown, this embodiment further integrates sliding and flipping mechanisms to achieve multi-degree-of-freedom adjustment to adapt to complex welding environments. The flipping frame 31 is not only slidably mounted on the swing arm 3, but can also be flipped at large angles through the hinge point of the side groove 15.

[0031] Specifically, the conical cover 22 on the secondary tube 21 is shielded by the stop block 32, and combined with the guide function of the through hole on the side plate 33 for the secondary tube 21 to pass through, it ensures that the secondary tube 21 can move and is limited during adjustment. The hinged design of the swing arm 3 allows the tilting frame 31 to swing 90 degrees in the horizontal plane, and combined with the sliding stroke, the conical cover 22 can cover a wide area around the suction table 1. The operator can fine-tune the conical cover 22 to the optimal position according to the shape of the workpiece and the welding position. For example, when multiple stations are used, multiple secondary tubes 21 can be tilted and adjusted at the same time to enhance the adaptability of the equipment.

[0032] Furthermore, the placement slot 11 of the suction table 1, in conjunction with the suction port 12, can efficiently capture welding fumes. The adjustable structure enhances its versatility, making it suitable for various industrial scenarios such as electronic welding and automobile manufacturing.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
