Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, specifically a multi-station laser welding machine with a fume treatment mechanism. Background Technology

[0002] Laser welding machines are used for laser welding in material processing. They utilize a high-energy-density laser beam as a heat source, focusing the beam into a very small area to create a localized high-temperature heat source. This causes the area to be welded to melt and solidify rapidly, thus achieving a strong connection between materials. Laser welding machines are widely used in many fields due to their high efficiency, diverse welding methods, excellent welding results, wide welding range, and high precision.

[0003] Prior art 1 (Chinese Patent No. CN217019087U, published on 2022-07-22) discloses a multi-station laser welding machine, comprising a welding machine body, the welding machine body including a housing, a fixing plate mounted on one side of the housing, a heat dissipation vent on the fixing plate, a control box fixed on the top of the housing, a display screen mounted on the control box, a switch mounted on one side of the display screen, and a movable seat mounted on one side of the control box. In use, the height of the movable seat is adjusted by an electric push rod to accommodate users of different heights, making it convenient to use. The rotating disc on the movable seat allows for the rotation and welding of heavier parts, avoiding the waste of labor caused by handling them.

[0004] While existing technology can be adjusted to suit users of different heights, it cannot handle the toxic fumes produced during welding. These fumes, when dispersed into the air, not only pollute the air but may also affect the user's health.

[0005] Therefore, we propose a multi-station laser welding machine with a flue gas treatment mechanism to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-station laser welding machine with a fume treatment mechanism to solve the problem that the device mentioned in the background art cannot treat the toxic fumes generated during welding, which not only pollute the air but may also affect the health of the user.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-station laser welding machine with a flue gas treatment mechanism, including a worktable, a threaded rod rotatably disposed on the upper surface of the worktable, a motor fixedly connected to the outer end of the threaded rod, and a laser welding head threadedly connected to the outer side of the threaded rod, a fixed frame fixedly connected below the laser welding head, a toothed plate disposed below the fixed frame, an adsorption hood disposed on the upper surface of the worktable, and a swinging mechanism capable of fully absorbing flue gas disposed between the outer side of the adsorption hood and the toothed plate.

[0008] Furthermore, a purification frame is fixedly connected to the upper surface of the workbench, and a filter element is fixedly connected inside the purification frame, with a connecting hose extending through the bottom of the purification frame.

[0009] Furthermore, a limiting frame is fixedly connected to the upper surface of the workbench, and a first spring is fixedly connected to the inner side of the limiting frame, and a clamping plate is fixedly connected to the outer side of the first spring. An anti-slip pad is fixedly connected to the bottom surface of the limiting frame.

[0010] Furthermore, the swing mechanism includes a limit rod, which is disposed above the worktable. The fixing frame is nested and connected to the outside of the limit rod. A fixing tube is rotatably connected to the upper surface of the worktable, and an adsorption cover is connected through the outside of the fixing tube. The bottom end of the fixing tube is connected through the other end of the connecting hose, and a half gear is fixedly connected to the outside of the fixing tube.

[0011] Furthermore, the half gear meshes with the toothed plate, and the fixed tube forms a rotating structure with the worktable surface through the half gear. The fixed frame forms a rotating structure with the threaded rod and the limiting rod.

[0012] Furthermore, a protrusion is fixedly connected to the outer surface of the limiting frame, a slide rod is nested on the fixing frame, a striking plate is fixedly connected to the inner side of the slide rod, and a second spring is fixedly connected between the outer end of the slide rod and the fixing frame.

[0013] Furthermore, the slide bar is elastically connected to the fixed frame via a second spring, and the protrusions are evenly distributed about the outer surface of the limiting frame, with both the protrusions and the outer side of the striking plate having an arc-shaped structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The upper surface of the worktable is equipped with three sets of limiting frames, which can place three workpieces for processing at the same time, improving processing efficiency. At the same time, the limiting frames are equipped with anti-slip pads, which can increase the friction of the workpieces. After the workpieces are placed, the first spring can apply pressure to the clamping plate under the drive of the elastic force, so that the clamping plate clamps the bottom of the workpiece. The clamping plate and the anti-slip pads work together to further improve the stability of the workpiece placement, so that the workpieces can be processed better in the future.

[0016] 2. After the workpiece is placed, start the motor. The motor will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the laser welding head to move synchronously. At this time, the laser welding head can drive the fixed frame set on the lower side to slide along the outer side of the limit rod. The laser welding head can move stably in position, thereby better welding the workpiece.

[0017] 3. An adsorption hood is installed on the upper surface of the workbench. The adsorption hood can draw in the flue gas and transport the drawn-in flue gas to the inside of the purification frame through a fixed pipe and a connecting hose. The filter element installed inside the purification frame can purify the flue gas before it is discharged, reducing the possibility of flue gas polluting the air or even affecting human health.

[0018] 4. When the fixed frame moves under the drive of the laser welding head, it can synchronously drive the toothed plate to move. At this time, the toothed plate can synchronously drive the fixed tube to rotate through the half gear meshing with it. The fixed tube then synchronously drives the adsorption hood to rotate. At this time, the adsorption hood can swing synchronously with the movement of the laser welding head, thereby accurately adsorbing the flue gas and improving the adsorption effect of the flue gas.

[0019] 5. As the fixed frame moves, it will simultaneously drive the striking plate to move. At this time, the protrusions on the outside of the purification frame will indirectly abut the striking plate. When the protrusions do not abut the striking plate, the striking plate can move to one side of the purification frame under the elastic force of the second spring, thereby striking the purification frame and reducing the amount of smoke and dust adhering to the filter screen on the outside of the filter element, thus preventing the filter element from becoming clogged.

[0028] Example 1: As Figure 1 and Figure 2 The technical solution shown herein provides the following technical solution: a multi-station laser welding machine with a fume treatment mechanism, which discloses a clamping plate 5 and an anti-slip pad 3. The clamping plate 5 and the anti-slip pad 3 cooperate with each other to further improve the stability of workpiece placement.

[0029] A threaded rod 8 is rotatably provided on the upper surface of the worktable 1, and a motor 7 is fixedly connected to the outer end of the threaded rod 8. A laser welding head 6 is threadedly connected to the outer side of the threaded rod 8. A limit frame 2 is fixedly connected to the upper surface of the worktable 1, and a first spring 4 is fixedly connected to the inner side of the limit frame 2. A clamping plate 5 is fixedly connected to the outer side of the first spring 4, and an anti-slip pad 3 is fixedly connected to the bottom surface of the limit frame 2.

[0030] The upper surface of the worktable 1 is provided with three sets of limiting frames 2, which can place three workpieces for processing at the same time, thus improving processing efficiency. At the same time, the limiting frames 2 are provided with anti-slip pads 3, which can increase the friction of the workpieces. After the workpieces are placed, the first spring 4 can apply pressure to the clamping plate 5 under the drive of the elastic force, so that the clamping plate 5 clamps the bottom of the workpiece. The clamping plate 5 and the anti-slip pads 3 work together to further improve the stability of the workpiece placement, so that the workpieces can be processed better in the future.

[0031] The upper surface of the worktable 1 is equipped with three sets of limiting frames 2, which can simultaneously place three workpieces for processing, improving processing efficiency. At the same time, the limiting frames 2 are equipped with anti-slip pads 3, which can increase the friction of the workpieces. After the workpieces are placed, the first spring 4 can apply pressure to the clamping plate 5 under the drive of elastic force, so that the clamping plate 5 clamps the bottom of the workpiece. The clamping plate 5 and the anti-slip pads 3 work together to further improve the stability of the workpiece placement, so that the workpieces can be processed better in the future.

[0032] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown is provided by the present utility model as follows: A multi-station laser welding machine with a flue gas treatment mechanism is disclosed, which includes a fixed frame 18. The fixed frame 18 reduces the phenomenon of dust clogging the filter screen by reducing the blockage of the filter element 11 on the outside. A purification frame 10 is fixedly connected to the upper surface of the workbench 1, and the filter element 11 is fixedly connected inside the purification frame 10. A connecting hose 12 is provided through the bottom of the purification frame 10. A protrusion 19 is fixedly connected to the outer surface of the limiting frame 2. A slide rod 21 is nested on the fixed frame 18, and a striking plate 20 is fixedly connected to the inner side of the slide rod 21. A second spring 17 is fixedly connected between the outer end of the slide rod 21 and the fixed frame 18. The slide rod 21 and the fixed frame 18 form an elastic structure through the second spring 17. The protrusions 19 are evenly distributed about the outer surface of the limiting frame 2, and the outer sides of the protrusions 19 and the striking plate 20 are both arranged in an arc shape.

[0033] After the workpiece is placed, motor 7 is started. Motor 7 drives the threaded rod 8 to rotate. As the threaded rod 8 rotates, it synchronously moves the laser welding head 6. The laser welding head 6 then drives the lower fixing frame 18 to slide along the outer side of the limiting rod 9. This allows the laser welding head 6 to move stably in position, thus better welding the workpiece. An adsorption hood 14 is installed on the upper surface of the worktable 1. The adsorption hood 14 draws in fumes, which are then transported to the purification frame 10 through the fixing pipe 15 and connecting hose 12. The filter element 11 inside the filter frame 10 can purify and discharge flue gas, reducing the possibility of flue gas polluting the air and even affecting human health. When the fixed frame 18 moves, it will simultaneously drive the knocking plate 20 to move. At this time, the protrusion 19 on the outside of the purification frame 10 indirectly abuts against the knocking plate 20. When the protrusion 19 does not abut against the knocking plate 20, the knocking plate 20 can move to one side of the purification frame 10 under the elastic force of the second spring 17, thereby knocking on the purification frame 10, reducing the amount of smoke and dust on the filter screen on the outside of the filter element 11, and preventing the filter element 11 from becoming clogged.

[0034] Example 3: Figure 3 , Figure 4 and Figure 5 The technical solution shown is provided by this utility model as follows: A multi-station laser welding machine with a flue gas treatment mechanism is disclosed, which can accurately adsorb flue gas and improve the adsorption effect of flue gas: a fixed frame 18 is fixedly connected to the lower part of the laser welding head 6, and a toothed plate 16 is provided below the fixed frame 18. An adsorption cover 14 is provided on the upper surface of the worktable 1, and an adsorption mechanism that can fully absorb flue gas is provided between the outer side of the adsorption cover 14 and the toothed plate 16. The adsorption mechanism includes a limit rod 9. 9 is set above the workbench 1. The fixing frame 18 is nested and connected to the outside of the limiting rod 9. The upper surface of the workbench 1 is rotatably connected to the fixing tube 15, and the outside of the fixing tube 15 is connected to the suction cover 14. The bottom end of the fixing tube 15 is connected to the other end of the connecting hose 12. The outside of the fixing tube 15 is fixedly connected to the half gear 13. The half gear 13 and the tooth plate 16 mesh with each other. The fixing tube 15 and the workbench 1 form a rotating structure through the half gear 13. The fixing frame 18 and the limiting rod 9 form a rotating structure through the threaded rod 8.

[0035] When the fixed frame 18 moves under the drive of the laser welding head 6, it can synchronously drive the toothed plate 16 to move. At this time, the toothed plate 16 can synchronously drive the fixed tube 15 to rotate through the half gear 13 meshing with it. The fixed tube 15 then synchronously drives the adsorption hood 14 to rotate. At this time, the adsorption hood 14 can swing synchronously with the movement of the laser welding head 6, thereby accurately adsorbing the flue gas and improving the adsorption effect of the flue gas.
