Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary devices, specifically relating to a dust collection device. Background Technology

[0002] Welding processes, especially the welding of metals, generate a large amount of fumes and harmful gases. These fumes not only pollute the working environment and affect the health of operators, but can also adhere to the weld surface, reducing weld quality and product reliability. Therefore, effectively collecting and treating the fumes generated during welding has become a crucial issue for improving welding equipment performance and ensuring production safety.

[0003] Currently, some welding equipment with dust removal functions already exists on the market. For example, fixed dust hoods are installed above or to the side of the welding area and connected to a central dust collection system via pipes. While this design can collect dust to some extent, the fixed position of the dust hood prevents it from moving with the welding head, resulting in limited dust collection effectiveness. This is especially problematic when welding complex shapes, as the dust hood struggles to cover all welding points, easily leading to dust leakage. To address this issue, some manufacturers have equipped their welding equipment with multiple dust hoods corresponding to each welding point, each equipped with an independent pipe. While this method improves dust collection to some extent, its complex structure increases production costs, occupies more space, and cannot flexibly adapt to different products. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a dust collection device that is compact in structure, highly efficient in dust collection, low in production cost, and can be flexibly adapted to the welding needs of different products.

[0005] The objective of this utility model can be achieved through the following technical solution: a dust collection device, assembled on welding equipment, comprising:

[0006] A substrate, which is disposed on the welding equipment, and has a plurality of welding holes;

[0007] The vacuuming pipe includes a first pipe and a second pipe. The first pipe is disposed on the substrate and has a plurality of openings corresponding one-to-one with the welding holes. The second pipe has a plurality of openings disposed on the first pipe and each second pipe is connected to at least two openings.

[0008] A power source is connected to the second pipe, and when the power source is started, a single second pipe can vacuum at least two of the welding holes.

[0009] In the aforementioned vacuuming device, the first pipe is further provided with a plurality of connection holes, each of the connection holes being connected to at least two of the openings, and a plurality of the second pipes corresponding to and connected to the connection holes one by one.

The first branch pipe is disposed on the first pipe and is detachably connected to the second branch pipe. The second branch pipe is disposed on the welding equipment and is connected to the power source. The substrate is detachably connected to the welding equipment.

[0012] In the aforementioned vacuuming device, the vacuuming pipe further includes a third pipe, which extends along the arrangement direction of the second branch pipes and communicates with a plurality of the second branch pipes, and the second branch pipes are connected to the power source through the third pipe.

[0013] In the aforementioned vacuuming device, a control valve is also provided between each of the second branch pipes and the third pipe, and the control valve can connect or disconnect the second branch pipe and the third pipe.

[0014] The aforementioned vacuuming device also includes a mounting bracket, which is detachably mounted on the welding equipment, and the control valve is detachably mounted on the mounting bracket and has a baffle that can be movably extended between the second branch pipe and the third pipe.

[0015] In the aforementioned vacuuming device, the baffle has a through hole along its length, and the diameter of the through hole is adapted to the diameter of the second branch pipe; when the through hole is opposite to the second branch pipe, the second branch pipe is connected to the third pipe; when the through hole is misaligned with the second branch pipe, the second branch pipe is disconnected from the third pipe.

[0016] In the aforementioned vacuuming device, each of the second branch pipes is provided with a filter screen at one end connected to the third pipe, and the filter screen is detachably connected to the second branch pipe.

[0017] In the aforementioned dust collection device, the substrate is further provided with a first connection structure and a second connection structure that are detachably connected to the welding equipment. The first connection structure is provided in two sets, located at both ends of the substrate. The second connection structure extends along the length of the substrate, and the extension length is greater than the length of the substrate.

[0018] Compared with existing technologies, the advantages of this invention are as follows: By configuring the suction pipe as a first pipe and several second pipes, and providing several openings on the first pipe that correspond one-to-one with the welding holes, the several second pipes are connected to the first pipe, and each second pipe is connected to at least two openings, thereby enabling a single second pipe to suction dust from at least two welding holes.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] like Figures 1 to 4 As shown, a dust collection device, assembled on a welding equipment, includes:

[0027] A substrate 100 is disposed on a welding device and has a plurality of welding holes 110 thereon.

[0028] The vacuuming pipe includes a first pipe 200 and a second pipe 300. The first pipe 200 is disposed on the substrate 100 and has a plurality of openings 210 corresponding one-to-one with the welding holes 110. A plurality of second pipes 300 are disposed on the first pipe 200, and each second pipe 300 is connected to at least two openings 210.

[0029] A power source (not shown in the figure) is connected to a second pipe 300. When the power source is activated, a single second pipe 300 can vacuum at least two welding holes 110. This design achieves comprehensive coverage of multiple welding points, effectively improving vacuuming efficiency, while also effectively reducing the number of pipes required, thereby simplifying the structure of the entire vacuuming device, reducing production costs, and saving space.

[0030] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the substrate 100 is rectangular and used to arrange the dust collection pipe to ensure the stability of the dust collection pipe during operation. The substrate 100 has several welding holes 110 arranged in a straight line along its length. These welding holes 110 penetrate the substrate 100, correspond to and communicate with the welding points of the workpiece, and are used for welding operations by welding equipment. It is worth noting that the number, position, and shape of the welding holes 110 can be arranged according to the welding requirements of different products. Preferably, in this embodiment, the welding holes 110 are circular, and there are two sets, each set containing ten welding holes 110, all arranged in a straight line.

[0031] In this embodiment, the substrate 100 is further provided with a first connecting structure 120 and a second connecting structure 130, which are detachably connected to the welding equipment. Two sets of the first connecting structure 120 are located at both ends of the substrate 100. The second connecting structure 130 extends along the length of the substrate 100, and its extension length is greater than the length of the substrate 100. The main function of the first connecting structure 120 is to fix the substrate 100 to the welding equipment, ensuring the substrate 100 remains stable during the welding process. It has two sets located at both ends of the substrate 100, forming a multi-point fixing method, which enhances the strength of the connection. The design of the second connecting structure 130 provides additional support for the substrate 100, preventing deformation or damage when the substrate 100 is subjected to force. This design is particularly suitable for applications requiring the resistance to large external forces or vibrations, effectively ensuring the stability and durability of the substrate 100. Furthermore, it can also serve as a gripping point for operators when assembling or disassembling the substrate 100, facilitating safe and stable handling of the substrate 100. This not only simplifies the disassembly and assembly process, but also avoids the risk of damage caused by the substrate 100 slipping or improper operation, thus improving the safety and convenience of operation.

[0032] Furthermore, the detachable design allows users to quickly replace the substrate 100 according to different welding needs. This detachable connection method includes bolt connections, snap-fit ​​connections, etc., the specific choice depending on the type of welding equipment and the operating environment. Preferably, in this embodiment, it is a bolt connection.

[0033] Preferably, in this embodiment, the first connecting structure 120 is disposed within the substrate 100, including a first extending edge 121 and a second extending edge 122. The first extending edge 121 extends from bottom to top, and the second extending edge 122 extends outward along the first extending edge 121, forming at least three contact surfaces in different directions, thereby realizing multi-point connection with the welding equipment, effectively ensuring the stability and reliability of the connection between the substrate 100 and the welding equipment, reducing welding defects caused by shaking or displacement of the substrate 100, and improving welding quality.

[0034] Preferably, in this embodiment, the second connecting structure 130 is rectangular and located between the two sets of first pipes 200, and is tightly fitted to the substrate 100. This design makes reasonable use of the space of the substrate 100, avoids occupying other space, and makes the entire vacuuming device more compact.

[0035] In this embodiment, the vacuuming duct includes a first duct 200 and a second duct 300. The first duct 200 is rectangular and elongated, disposed on the substrate 100 and extending along the arrangement direction of the welding holes 110. The first duct 200 has a plurality of rectangular openings 210 on the side facing the welding holes 110, each corresponding to one of the welding holes 110. Preferably, the length of the openings 210 is adapted to the diameter of the welding holes 110. The one-to-one correspondence between the openings 210 and the welding holes 110 allows the vacuuming duct to precisely cover all welding points, effectively ensuring the efficiency and accuracy of vacuuming.

[0036] Preferably, in this embodiment, the first pipe 200 is provided in two sets, each corresponding to one of the two sets of welding holes 110, and the openings 210 on the two sets of first pipes 200 are arranged opposite to each other. This design further ensures coverage of the welding points and improves the convenience of dust extraction pipe layout.

[0037] In this embodiment, several second pipes 300 are bent and detachably mounted on the first pipe 200, with each second pipe 300 connected to at least two openings 210. The connection between the second pipes 300 and the two openings 210 allows each second pipe 300 to precisely cover at least two welding holes 110 during operation, effectively reducing the number of pipes required and lowering production costs while ensuring dust collection efficiency.

[0038] In this embodiment, the first pipe 200, on the side facing away from the welding equipment, is also provided with a plurality of circular connecting holes 220 arranged in a straight line. These connecting holes 220 extend from top to bottom, wherein each connecting hole 220 communicates with at least two openings 210, and a plurality of second pipes 300 correspond one-to-one with and communicate with the connecting holes 220. This design allows a single second pipe 300 to communicate with two openings 210 by connecting to one connecting hole 220, which not only improves the convenience of connecting the second pipes 300, but also reduces the possibility of air leakage and improves dust collection efficiency. In addition, especially when the gap between two openings 210 is large, the design of the connecting holes 220 can effectively reduce the diameter requirement of the second pipes 300, ensuring the compactness of the overall structure.

[0039] In this embodiment, adjacent openings 210 may or may not be connected. Preferably, in this embodiment, the two openings 210 corresponding to each connecting hole 220 are interconnected, and the openings 210 between adjacent connecting holes 220 are not connected. Compared to all openings 210 being connected, this design avoids mutual interference of suction between adjacent second pipes 300, affecting the dust collection effect of each welding hole 110; compared to all openings 210 being unconnected, this design reduces the transmission path of suction within the pipes, lowers the resistance inside the pipes, and further improves dust collection efficiency. Overall, this design not only improves dust collection efficiency but also enhances the reliability of the dust collection device.

[0040] Because different products have different shapes and structures, the welding positions also differ. Traditional vacuum cleaner heads are typically fixed, failing to meet the dust removal needs of various products. Therefore, in this embodiment, each second pipe 300 includes a first branch pipe 310 and a second branch pipe 320 that are interconnected. The first branch pipe 310 is mounted on the first pipe 200 and detachably connected to the second branch pipe 320. The second branch pipe 320 is mounted on the welding equipment and connected to a power source. The substrate 100 is detachably connected to the welding equipment. This segmented design of the second pipe 300 allows users to replace different substrates 100 as needed, thereby adapting to different products and meeting their welding requirements, effectively improving the adaptability of the vacuum cleaner.

[0041] Preferably, in this embodiment, the first branch pipe 310 is bent, with one end detachably connected to the first pipe 200 via bolts, and the other end detachably connected to the second branch pipe 320 via a flexible hose (not shown in the figure); the second branch pipe 320 is straight, with one end detachably connected to the third pipe 400, and the other end detachably connected to the first branch pipe 310 via a flexible hose. This detachable connection design allows users to quickly disassemble and replace faulty pipe sections, reducing downtime. Furthermore, when switching between different products or welding tasks, users can detach the flexible hose from the first branch pipe 310 of one substrate 100 and reconnect it to the first branch pipe 310 of another substrate 100, allowing for rapid adjustment of the dust collection device configuration and ensuring effective dust collection at each welding point, thus significantly improving production continuity and efficiency.

[0042] In this embodiment, the vacuum duct also includes a third duct 400, which extends along the arrangement direction of the second branch ducts 320 and communicates with several second branch ducts 320. The second branch ducts 320 are connected to the power source via the third duct 400. This design achieves centralized vacuum path management, effectively simplifies the duct layout, reduces the number of ducts, and further reduces the complexity of installation and maintenance.

[0043] Preferably, in this embodiment, the third pipe 400 has a hollow structure, with a rectangular tube in the middle and round tubes at both ends. The rectangular tube is detachably connected to the welding equipment, and has multiple ventilation holes corresponding one-to-one with the second branch pipe 320. The second branch pipe 320 is vertically connected to the rectangular tube. This design ensures convenient connection between the second branch pipe 320 and the third pipe 400, as well as between the third pipe 400 and the welding equipment.

[0044] Preferably, in this embodiment, both ends of the third pipe 400 can be connected to the outside, enabling connection between multiple sets of third pipes 400.

[0045] In this embodiment, a control valve 500 is also provided between the second branch pipe 320 and the third pipe 400, and the control valve 500 can connect or disconnect the second branch pipe 320 and the third pipe 400. By setting a control valve 500 between each second branch pipe 320 and the third pipe 400, the user can flexibly control the start and stop of each second branch pipe 320 according to actual welding needs. This design allows the dust collection device to respond more precisely to welding operations, improving dust collection efficiency and welding quality. Furthermore, the on / off operation of the control valve 500 can avoid unnecessary energy waste and equipment wear, extending the service life of the equipment. In addition, during certain welding processes, if it is necessary to temporarily disconnect the dust collection function of a certain second branch pipe 320, the control valve 500 can effectively prevent air leakage, ensuring that the dust collection effect of other welding points is not affected. This not only improves dust collection efficiency but also avoids welding quality problems caused by air leakage.

[0046] In this embodiment, a mounting bracket 600 is also included. This mounting bracket 600 is n-shaped and detachably mounted on the welding equipment via bolts. The control valve 500 is detachably mounted on the mounting bracket 600 and has a baffle 510 that can be movable to extend between the second branch pipe 320 and the third pipe 400. The introduction of this mounting bracket 600 allows users to flexibly install and remove the control valve 500 according to actual needs, improving the convenience of installation and operation, while also ensuring the stability of the control valve 500 installation. The baffle 510 design of the control valve 500 effectively controls the connection between the second branch pipe 320 and the third pipe 400. Specifically, when the baffle 510 extends, it effectively blocks the connection between the second branch pipe 320 and the third pipe 400, preventing air leakage. This design ensures that the dust extraction effect of each welding point is independent and effective, avoiding welding quality problems caused by air leakage.

[0047] Because the baffle 510 needs to move a relatively long distance, the response time is long. Especially in multi-station welding or high-frequency welding tasks, the frequent insertion and removal of the baffle 510 may cause significant delays, affecting welding efficiency and quality.

[0048] Therefore, in this embodiment, the baffle 510 is vertically arranged between the second branch pipe 320 and the third pipe 400, and the baffle 510 has a through hole 511 along its length, the diameter of which is adapted to the diameter of the second branch pipe 320. When the through hole 511 is opposite to the second branch pipe 320, the second branch pipe 320 is connected to the third pipe 400; when the through hole 511 is misaligned with the second branch pipe 320, the second branch pipe 320 is disconnected from the third pipe 400. This design makes the movement stroke of the baffle 510 very short; the on / off operation can be achieved by rotating or translating the through hole 511 a small distance relative to the second branch pipe 320. Specifically, the baffle 510 only needs to move a distance equal to the diameter of the through hole 511 to complete the switching of the dust collection path, without having to move the entire baffle 510 out. Furthermore, it can reduce the friction area between the baffle 510 and the pipe, reduce the wear of mechanical parts, and extend the service life of the equipment.

[0049] In this embodiment, a filter screen 700 is provided at the end where each second branch pipe 320 and the third pipe 400 connect, and the filter screen 700 is detachably connected to the second branch pipe 320. This design can effectively filter the fumes and harmful gases generated during welding, prevent particulate matter and other impurities from entering the power source and causing damage, and effectively extend the service life of the vacuum cleaner. The detachable connection between the filter screen 700 and the second branch pipe 320 allows users to easily disassemble and clean the filter screen 700, reducing maintenance time and costs, and enabling users to regularly replace or clean the filter screen 700 according to actual usage, ensuring that the vacuum cleaner is always in optimal working condition.

[0050] In this embodiment, the power source is a fan, which is connected to the third pipe 400 to generate suction in the dust collection pipe, thereby removing dust during the welding process.

[0051] In this embodiment, the welding equipment includes at least one workbench 800, a dust extraction device is detachably mounted on the workbench 800, and the workbench 800 is provided with a mounting groove 810 into which the substrate 100 extends, so that the workpiece can abut against the substrate 100 from below to perform welding work.
