Description

Technical Field

[0001] This invention relates to the field of packaging material welding technology, and in particular to an automated welding production line. Background Technology

[0002] Paint buckets are containers used for storing and transporting paint. They are primarily made of metal, making them suitable for heavy-duty transport. The manufacturing process includes raw material processing, forming, and final standard airtightness testing. Welding equipment is mainly used in the process of welding thin metal sheets into barrel-shaped packaging materials. The metal sheets undergo several steps, including rolling, welding, and bottom welding, to create the metal buckets. Currently, most production uses laser welding technology. However, the production process is largely manual, with low automation and low efficiency. Furthermore, the lack of positioning and alignment capabilities makes it easy for poor welding results to occur during transportation. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an automated welding production line.

[0004] Preferably, the assembly includes a support machine, a welder, and a transport assembly, wherein a movable assembly is provided on the top of the support machine, and a support assembly is provided on the outer wall of the support machine;

[0005] The transport component is equipped with a tilting component; the transport component is equipped with a limiting component; the transport component is equipped with a paint bucket;

[0006] The transport component includes a support frame, a rotating rod rotatably connected to the support frame, a sprocket fixedly connected to the outer wall of the rotating rod, and a chain provided on the support frame, the chain meshing with the sprocket;

[0007] The flipping assembly includes a round rod, the two ends of which are rotatably connected to one side of a support frame via bearings. A rotating plate is fixedly connected to the outer wall of the round rod, and a flipping rod is fixedly connected to the outer wall of the rotating plate. The flipping rod is rectangularly distributed. A fixing rod is fixedly connected to the outer wall of the round rod, and a pressing rod is fixedly connected to the end of the fixing rod away from the round rod. A fixing plate is detachably connected to the side of the chain away from the support frame, and a pressing block is fixedly connected to the fixing plate. One side of the pressing block is inclined.

[0008] Preferably, the moving component includes a conveyor belt, the outer wall of which is detachably connected to the top of the support machine. A connecting rod is detachably connected to the outer wall of the guide belt of the conveyor belt. An adsorption plate is fixedly connected to the end of the connecting rod away from the guide belt. The side of the adsorption plate away from the connecting rod is arc-shaped and fits against the outer wall of the paint bucket. By setting up the moving component, the paint bucket can be stably transported. Through magnetic adsorption, the bucket-shaped prototype can be firmly fixed on the surface of the conveyor belt, preventing displacement or shaking after entering the full welding area and before welding. This allows for precise positioning of the metal paint bucket and ensures welding accuracy.

[0009] Preferably, the support assembly includes a placement plate, the outer wall of which is fixedly connected to the outer wall of the support machine. A support plate is detachably connected to the top of the placement plate, and a diagonal strip is detachably connected to the top of the support plate. The diagonal strip is inclined. By setting up the placement plate, support plate, and diagonal strip, the metal paint bucket is supported, thereby guiding the workpiece to automatically correct its position and ensuring that the bottom of the bucket is precisely aligned with the welding trajectory of the welding gun. At the same time, it ensures that the workpiece maintains a stable shape during transmission and welding, avoiding welding gap deviation caused by uneven force. It also allows the workpiece to pass through the welding station continuously and orderly, improving the efficiency of automated continuous operation of the entire welding process, which meets the design goals of the entire production line.

[0010] Preferably, the outer wall of the inclined bar is rotatably connected to a rotating wheel, which is symmetrically distributed on the inclined bar. The outer wall of the rotating wheel is in contact with the outside of the paint bucket. By setting the rotating wheel, the metal paint bucket can be moved smoothly. The rotating wheel can distribute the force through its rolling characteristics and adapt to the arc-shaped bottom contour of the barrel-shaped workpiece in a flat state, ensuring that the workpiece maintains a stable shape during the transfer and welding process, avoiding welding gap deviation caused by uneven force. At the same time, the rotation can reduce the transfer resistance, ensure that the workpiece moves at a uniform speed, and avoid jamming or deviation.

[0011] Preferably, the limiting component includes a first mounting plate, the bottom of which is fixedly connected to the top of the support frame. A bolt is threadedly connected to the top of the first mounting plate. A limiting strip is rotatably connected to one end of the bolt passing through the first mounting plate. A nut is threadedly connected to the other side of the bolt passing through the first mounting plate. The outer wall of the nut is in contact with one side of the first mounting plate. A magnetic block is provided on the side of the first mounting plate in contact with the nut. By setting the first mounting plate, bolt, limiting strip, and nut, the metal paint bucket is limited. This limits the movement trajectory of the metal paint bucket during the flipping process, ensuring that the axis of the bucket is completely aligned with the vertical direction after flipping. It also prevents the bucket from leaving the equipment track during the flipping process, avoiding safety risks such as falling and collision, and meeting the safety specifications of industrial automated production lines.

[0012] Preferably, a flexible strip is fixedly connected to the side of the limiting strip away from the bolt. The outer wall of the flexible strip is provided with a smooth coating. By setting the flexible strip, the friction during the transportation of the metal paint bucket is reduced, thereby facilitating the transportation of the metal paint bucket and ensuring that the metal paint bucket is more stable during transportation, thus avoiding affecting the turning efficiency of the metal paint bucket.

[0013] Preferably, a second mounting plate is connected to the top of the support frame, and a limiting rod is slidably connected to the top of the second mounting plate. The limiting rod passes through one side of the second mounting plate and is fixedly connected to one side of the limiting strip. By setting the second mounting plate and the limiting rod, the limiting strip is limited, thereby avoiding positional deviation of the limiting strip during adjustment, thus avoiding affecting the limiting strip's position on the metal paint bucket, and further avoiding affecting the transmission efficiency of the metal paint bucket.

[0014] Preferably, the end of the inclined bar away from the support frame is fixedly connected to an inclined rod. The inclined rod is set in an inclined shape. By setting the inclined rod, the metal paint bucket can be stably transported. After the metal paint bucket is spot welded, when it is transported to the full welding area, the inclined rod can ensure that the metal paint bucket is stably transported to the full welding area, thereby reducing manual intervention during the transport of the metal paint bucket and avoiding affecting the processing efficiency of the metal paint bucket.

[0015] In summary, the present invention provides an automated welding production line with the following beneficial effects:

[0016] 1. By setting up transport and flipping components, the fully welded metal paint buckets are transported and flipped after welding. The fully welded metal paint buckets are transported to subsequent processes via the transport components. During transportation, the metal paint buckets will automatically flip to the left and right of the flipping components, thereby significantly shortening the process flow time of a single workpiece. This is especially suitable for batch production scenarios, significantly improving the overall capacity of the production line. At the same time, it can make the flipping action more gentle, protecting the integrity of the outer surface of the packaging bucket and ensuring product quality.

[0017] 2. By setting up a moving component, stable transmission of the paint bucket is achieved. Through magnetic adsorption, the bucket-shaped prototype can be firmly fixed on the surface of the conveyor belt, preventing displacement or shaking after entering the full welding area and before welding. This allows for precise positioning of the metal paint bucket, ensuring welding accuracy. At the same time, the magnetic transmission provides more uniform force, which can smoothly move the workpiece to the welding station and reduce scratch damage to the workpiece surface during transmission, ensuring the integrity of the product appearance. It can also quickly fix and release the workpiece, allowing the workpiece to enter the welding station continuously and orderly, avoiding jamming and improving the automation and continuous operation capability of the entire welding process.

[0018] 3. By setting up support components, the metal paint bucket is transported. When the workpiece is transported from the spot welding area to the full welding area, the inclined surface of the roller group will generate lateral limiting force on both sides of the workpiece, guiding the workpiece to automatically correct its position, ensuring that the bottom of the bucket is accurately aligned with the welding trajectory of the welding gun, and avoiding welding deviation problems of the paint bucket, improving the sealing and dimensional consistency of the weld base. At the same time, the rolling characteristics of the rollers can distribute the force, adapt to the arc-shaped bottom contour of the bucket workpiece in the flat state, and ensure that the workpiece maintains its shape stability during the transport and welding process, avoiding welding gap deviation caused by uneven force.

[0019] 4. By setting limit components, the metal paint bucket is limited, ensuring that the bucket's axis is perfectly aligned with the vertical direction after flipping. This avoids problems in subsequent processes due to workpiece position deviations and allows for pre-definition of the workpiece's flipping range and posture, ensuring smooth and unobstructed rotation of the cross-shaped rotating rod and preventing jamming or sticking. This guarantees the stability of the flipping process's cycle time and forms an efficient connection with the preceding transmission and subsequent storage processes, further enhancing the automation efficiency of the entire production line. Simultaneously, it can create a closed or semi-closed flipping space, firmly confining the workpiece within a safe range and preventing it from detaching from the equipment track during flipping, thus avoiding safety risks such as falling and collisions, and meeting the safety specifications of industrial automated production lines.

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.

[0037] Example

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the present invention provides a technical solution: an automatic welding production line, including a support machine 1, a welder 2, and a transport component 3. The support machine 1 is connected to a spot welding area, which is used to roll iron sheets into barrels and spot weld the rolled iron sheets to ensure stable movement of the rolled iron sheets. The welder 2 can perform full welding on the spot-welded paint buckets 9. A moving component 4 is provided on the top of the support machine 1; the moving component 4 can transport the spot-welded paint buckets 9 to ensure stable transport of the spot-welded paint buckets 9, thereby ensuring the full transport of the paint buckets 9. To ensure welding quality, the outer wall of the support machine 1 is equipped with a support component 5. The support component 5 can stabilize the paint bucket 9 during transportation and can also calibrate the paint bucket 9 to ensure the welding quality of the paint bucket 9. The transport component 3 is equipped with a flipping component 6. The flipping component 6 can flip the paint bucket 9 to facilitate subsequent processing of the paint bucket 9. The transport component 3 is equipped with a limit component 7. The limit component 7 can limit the paint bucket 9 to ensure stable flipping of the paint bucket 9. The transport component 3 is equipped with the paint bucket 9.

[0039] The transport component 3 includes a support frame 301, of which two support frames 301 are provided. Rotating rods 304 are rotatably connected to the support frames 301, supporting the rotating rods 304. Two rotating rods 304 are provided, symmetrically distributed. Sprockets 302 are fixedly connected to the outer wall of each rotating rod 304, with two sprockets 302 on each rod. A chain 303 is provided on the support frame 301, meshing with the sprockets 302. The sprockets 302 allow the chain 303 to move, thereby transporting the paint bucket 9 via the chain 303. The flipping component 6 includes a round rod 601, with both ends rotatably connected to one side of the support frame 301 via bearings. The round rod 601 can rotate on the support frame 301. A rotating plate 602 is fixedly connected to the outer wall of the round rod 601, allowing the round rod 601 to rotate. The rotating plate 602 is rotated, and a flipping rod 603 is fixedly connected to the outer wall of the rotating plate 602. The rotation of the rotating plate 602 can drive the flipping rod 603 to rotate. The flipping rod 603 is rectangularly distributed. A fixing rod 604 is fixedly connected to the outer wall of the round rod 601. Multiple fixing rods 604 are provided on the round rod 601. A pressing rod 605 is fixedly connected to the end of the fixing rod 604 away from the round rod 601. Each fixing rod 604 is provided with a pressing rod 605. A fixing plate 606 is detachably connected to the side of the chain 303 away from the support frame 301. A pressing block 607 is fixedly connected to the fixing plate 606. The fixing plate 606 can install the pressing block 607. One side of the pressing block 607 is set in an inclined shape. The pressing block 607 can push the pressing rod 605 to flip, thereby driving the flipping rod 603 to flip, thus realizing the flipping of the paint bucket 9.

[0040] like Figure 2As shown, the moving component 4 includes a conveyor belt 401, which can transport the metal paint bucket 9. The outer wall of the conveyor belt 401 is detachably connected to the top of the support machine 1. Two sets of conveyor belts 401 are provided, and the two sets of conveyor belts 401 are symmetrically distributed. Connecting rods 402 are detachably connected to the outer wall of the guide belt of the conveyor belt 401. Each conveyor belt 401 is provided with a large number of connecting rods 402. An adsorption plate 403 is fixedly connected to the end of the connecting rod 402 away from the guide belt of the conveyor belt 401. Each connecting rod 402 is provided with an adsorption plate 403. The side of the adsorption plate 403 away from the connecting rod 402 is set as an arc. The arc surface of the adsorption plate 403 can interact with the oil. The outer surface of the paint bucket 9 is more closely fitted, and the side of the adsorption plate 403 away from the connecting rod 402 is attached to the outer wall of the paint bucket 9. The use of the adsorption plate 403 can firmly fix the bucket-shaped prototype on the surface of the conveyor belt, preventing it from shifting or shaking after entering the full welding area and before welding. This allows for precise positioning of the metal paint bucket 9, ensuring welding accuracy. At the same time, the magnetic conveying force is more uniform, which can not only smoothly move the workpiece to the welding station, but also reduce the scratch damage to the workpiece surface during the transmission process, ensuring the integrity of the product appearance. It can also quickly fix and release the workpiece, allowing the workpiece to enter the welding station continuously and orderly, avoiding jamming, and improving the automation and continuous operation capability of the full welding process.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 5 includes a placement plate 501, the outer wall of which is fixedly connected to the outer wall of the support machine 1. The support machine 1 can install the placement plate 501. A support plate 502 is detachably connected to the top of the placement plate 501, and the placement plate 501 can fix the support plate 502. There are four support plates 502, with every two support plates 502 forming a group. A diagonal strip 503 is detachably connected to the top of the support plate 502, and the support plate 502 can install the diagonal strip 503. Two diagonal strips 503 are provided. Two inclined bars 503 are symmetrically distributed and are set in an inclined position to support the metal paint bucket 9. This guides the workpiece to automatically correct its position, ensuring that the bottom of the bucket is precisely aligned with the welding trajectory of the welding gun. It also ensures that the workpiece maintains a stable shape during transmission and welding, avoiding welding gap deviations caused by uneven force. Furthermore, it allows the workpiece to pass through the welding station continuously and orderly, improving the efficiency of automated continuous operation of the entire welding process, which is in line with the design goals of the entire production line.

[0042] like Figure 2 and Figure 3As shown, a rotating wheel 504 is rotatably connected to the outer wall of the inclined bar 503. There are two sets of rotating wheels 504, with multiple rotating wheels 504 in each set. The rotating wheels 504 are symmetrically distributed on the inclined bar 503. The outer wall of the rotating wheel 504 is in contact with the outside of the paint bucket 9. The use of the rotating wheel 504 can distribute the force through its rolling characteristics, adapt to the arc-shaped bottom contour of the barrel-shaped workpiece in a flat state, ensure that the workpiece maintains a stable shape during the transmission and welding process, and avoid welding gap deviation caused by uneven force. At the same time, the rotation can reduce the transmission resistance, ensure that the workpiece moves at a uniform speed, and avoid jamming or deviation.

[0043] like Figure 1 , Figure 5 and Figure 8 As shown, the limiting component 7 includes two first mounting plates 701, which are symmetrically distributed. The bottom of each first mounting plate 701 is fixedly connected to the top of the support frame 301. Two bolts 702 are threaded onto the top of each first mounting plate 701, one on each first mounting plate 701. Each bolt 702 passes through one end of the first mounting plate 701 and is rotatably connected to a limiting strip 703. Two limiting strips 703 are provided, one on each bolt 702. The bolts 702 can... The spacing between the two limiting strips 703 can be adjusted to accommodate paint buckets 9 of different diameters. A bolt 702 passes through one side of the first mounting plate 701 and is threaded with a nut 704. Each bolt 702 is provided with a nut 704. The outer wall of the nut 704 is in contact with one side of the first mounting plate 701. The nut 704 can lock the bolt 702 to ensure the stability of the bolt 702. A magnetic block is provided on the side of the first mounting plate 701 that is in contact with the nut 704. The magnetic block on the first mounting plate 701 can increase the stability between the nut 704 and the first mounting plate 701.

[0044] like Figure 2 Figure 8 As shown, a flexible strip 705 is fixedly connected to the side of the limiting strip 703 away from the bolt 702. Two flexible strips 705 are provided, and the two flexible strips 705 are symmetrically distributed. The distance between the two flexible strips 705 is the same as the diameter of the paint bucket 9. The outer wall of the flexible strip 705 is provided with a smooth coating. The smooth coating on the surface of the flexible strip 705 can reduce the friction during the transportation of the metal paint bucket 9, thereby facilitating the transportation of the metal paint bucket 9 and ensuring that the metal paint bucket 9 is more stable during transportation, thus avoiding affecting the flipping efficiency of the metal paint bucket 9.

[0045] like Figure 2 , Figure 4 and Figure 8As shown, the top of the support frame 301 is connected to a second mounting plate 706. There are four second mounting plates 706, arranged in pairs, and the two sets of second mounting plates 706 are symmetrically distributed. The top of the second mounting plate 706 is slidably connected to a limit rod 707. There are four limit rods 707, arranged in pairs, and the two sets of limit rods 707 are symmetrically distributed. One side of the limit rod 707 passes through the second mounting plate 706 and is fixedly connected to one side of the limit strip 703. The second mounting plate 706 can limit the limit rod 707, and the limit rod 707 can limit the limit strip 703, thereby preventing the limit strip 703 from deviating in position during adjustment, thus avoiding affecting the limit strip 703's limit on the metal paint bucket 9, and thus avoiding affecting the transmission efficiency of the metal paint bucket 9.

[0046] like Figure 2 and Figure 3 As shown, an inclined rod 8 is fixedly connected to the end of the inclined bar 503 away from the support frame 301. There are two inclined rods 8, which are symmetrically distributed. The inclined rods 8 are inclined, and the higher end of the inclined rod 8 is close to the spot welding area of ​​the metal paint bucket 9. This can ensure that the metal paint bucket 9 is stably transported to the full welding area, thereby reducing manual intervention during the transport of the metal paint bucket 9 and avoiding affecting the processing efficiency of the metal paint bucket 9.

[0047] Working principle:

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this automatic welding production line is installed in the required position during use. The staff inspects the equipment to ensure its stability during transportation. After the equipment inspection is completed, the staff adjusts the equipment as needed. When adjusting the limit component 7, the distance between the limit bars 703 can be adjusted by the cooperation of bolts 702 and nuts 704, so that the limit bars 703 can limit the paint bucket 9. After the adjustment is completed, the staff starts the equipment.

[0049] After the sheet metal is rolled into a barrel and spot-welded, it is moved to the rotating wheel 504 by the inclined bar 8. At this time, the conveyor belt 401 will drive the connecting bar 402 and the adsorption plate 403 to move. When the adsorption plate 403 moves, it will transport the spot-welded paint bucket 9, so as to make the paint bucket 9 more stable during the full welding. When the paint bucket 9 is transported by the adsorption plate 403, the inclined bar 503 and the rotating wheel 504 will calibrate the position of the paint bucket 9 and ensure the stable transmission of the paint bucket 9, thereby realizing the welding of the paint bucket 9. After the paint bucket 9 is welded, it moves to the chain 303.

[0050] The paint bucket 9, which moves onto the chain 303, will move slowly as the chain 303 moves. While the chain 303 is moving the paint bucket 9, it also moves the extrusion block 607. The movement of the extrusion block 607 will extrude the extrusion rod 605, thereby causing the flipping rod 603 and the rotating plate 602 to rotate through the extrusion rod 605 and the fixed rod 604. This causes the paint bucket 9 to flip through the flipping rod 603, thus facilitating subsequent processing of the paint bucket 9.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
