Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an automatic positioning and rotating welding device for IBC barrel frames. Background Technology

[0002] In the industrial packaging field, IBC (medium bulk container) drums are widely used in industries such as chemical, food, and pharmaceutical due to their advantages such as large capacity, high strength, and ease of transportation and storage. They are usually composed of a plastic liner and a metal frame. During the manufacturing process of the IBC drum frame, it is necessary to accurately weld the load-bearing components (such as the base and support feet) to the four arc-shaped corners of the frame. At the same time, it is also necessary to weld the crossbeams, valve mounting plates, and other components to the designated positions on the frame. The positional accuracy and quality of these welding points have a decisive impact on the subsequent installation of the liner and the stability of the entire drum.

[0003] Currently, the welding production of IBC bucket frames still commonly employs semi-automatic or manual welding methods. In this method, the positioning of load-bearing components typically relies on manual placement and adjustment. Operators must first place the load-bearing component on the support fixture, then adjust its position visually or with simple measuring tools to align its arc midpoint with the arc edge of the frame before welding. This manual positioning method not only makes it difficult to guarantee positioning accuracy, but also requires repeated adjustments for each load-bearing component, severely hindering production efficiency. Furthermore, when the IBC bucket frame is subsequently hoisted or placed onto the positioned load-bearing components, the components are prone to displacement or rotation due to external impacts, causing the already adjusted positioning to fail and requiring readjustment, further reducing production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to move the load-bearing component to the target position quickly and stably, and to this end, an automatic positioning and rotating welding device for IBC barrel frame is provided.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic positioning and rotary welding device for IBC barrel frames, comprising a base, a welding host, a gripping mechanism, and a translation frame. The base has a U-shaped structure, providing an installation foundation for each component. Several first support mechanisms (which support the load-bearing components) are provided on the base. A second support mechanism (which supports the crossbeam) is provided between two adjacent first support mechanisms. A welding host is provided on the side of each first and second support mechanism. The welding host is connected to the base via a first horizontal drive component. To achieve precise and stable welding of the load-bearing components to the bottom of the IBC barrel frame, this device uses four first support mechanisms. The positions of the four first support mechanisms correspond one-to-one with the four arc-shaped corners of the IBC barrel frame. The first support mechanisms support and position the load-bearing components. Compared to currently used support components, the first support mechanism in this device includes a positioning seat. The positioning seat contains a connecting block, a rotating disk, and a rotary drive component. The rotary drive component is connected to the rotating disk via a transmission assembly. The connecting block is located at the end of the rotating disk away from the rotating drive component. A through hole is provided at the end of the connecting block away from the rotating disk. A negative pressure adsorption component is installed inside the connecting block. Before welding, the carrier is placed on the positioning seat, and then the negative pressure adsorption component is activated. The carrier and the connecting block are fastened together through the negative pressure adsorption component and the through hole on the connecting block. This prevents the carrier from shifting or rotating relative to the connecting block due to collisions or other reasons when the IBC barrel frame is placed on the carrier, thus providing a reliable foundation for subsequent automated welding processes. Finally, when placing the carrier on the positioning seat, the operator often needs to manually adjust the position of the carrier so that the midpoint of the carrier's arc aligns with the midpoint of the arc at the end of the positioning seat, thereby ensuring that the relative position of the carrier and the arc edge of the IBC barrel frame meets the requirements. In this invention, when the carrier and the connecting block are fastened together, the rotating disk and the connecting block can be rotated by the rotating drive component, thereby rotating the carrier to the target position. Through the above technical solution, the accuracy of position adjustment is improved on the one hand, and the inconvenience of manual operation is reduced on the other.

[0006] Furthermore, a deflection shaft is provided at the center of the rotating disk, a flat key is provided on the rotating disk, and a groove is provided on the deflection shaft. The rotating disk is connected to the deflection shaft via a keyway fit. The deflection shaft has axial movement function. The transmission assembly includes a first gear and a second gear. The first gear is connected to the rotating disk, and the second gear is connected to the rotary drive component. A clamping assembly is provided at the center of the first gear. One end of the deflection shaft is located in the clamping assembly, and the other end of the deflection shaft extends out of the positioning seat. The clamping assembly fixes the deflection shaft to the first gear. In this invention, the rotary drive component has a self-locking function. When the rotary drive component is working normally, the operator can drive the rotating disk and connecting block to rotate through the rotary drive component, thereby driving the bearing component to rotate. The self-locking property of the rotary drive component prevents the IBC bucket frame from deflecting when placed onto the carrier. If the rotary drive malfunctions, the operator can pull the deflection shaft out of the first gear and manually rotate it. The rotating disk and connecting block will continue to rotate the carrier. Once the carrier reaches the target position, the deflection shaft is reinserted into the first gear. The clamping assembly and the deflection shaft work together to secure the first gear and rotating disk together again. Through this technical solution, the invention ensures that the carrier will not deflect unexpectedly due to external forces when the IBC bucket frame is placed onto the carrier and during welding, thus guaranteeing accurate weld positioning. Furthermore, it enables rapid emergency response, significantly reducing equipment downtime and improving production efficiency and maintainability.

[0007] Furthermore, the clamping assembly includes several clamping blocks, each of which is connected to the first gear via a compression spring, allowing the clamping block to move radially relative to the center of the first gear. When the deflection shaft moves out of the clamping blocks, the first gear slides in connection with the rotating disk. When the deflection shaft is inserted into the clamping blocks, the clamping assembly can fix the deflection shaft and the first gear together, thereby ensuring that the first gear and the rotating disk rotate synchronously. Finally, each clamping block in this invention has a chamfer at one end near the center line of the first gear to serve as a guide. In addition, the width of each clamping block is greater than the width of the groove on the deflection shaft to provide a stable and reliable clamping force and ensure torque transmission.

[0008] Furthermore, a second cavity is provided inside the connecting block near the through hole. The negative pressure adsorption assembly includes a movable frame and a second electromagnet. One end of the movable frame is located inside the second cavity, and the other end of the movable frame is located near the second electromagnet. When the carrier is placed on the positioning seat, the second electromagnet is energized to generate magnetic force, which attracts the movable frame to move away from the through hole, thereby expanding the volume between the second cavity and the through hole. This creates a negative pressure between the second cavity and the through hole, thus firmly adsorbing the carrier onto the connecting block. This facilitates the automatic positioning and rotation of the carrier by the rotation drive, and also prevents the carrier from shifting or rotating due to external force when the IBC bucket frame is placed on it.

[0009] Furthermore, to accommodate BC barrel frames of different lengths or specifications, the first support mechanism of this invention also includes a mounting base and a second horizontal drive component. The mounting base is directly fixed to the machine base, while the positioning seat is slidably connected to the mounting base via the second horizontal drive component. By controlling the extension and retraction of the second horizontal drive component, the position of the positioning seat relative to the mounting base can be precisely adjusted, thereby changing the span between adjacent first support mechanisms. This allows the equipment to be compatible with the production of IBC barrel frames of different sizes, improving the versatility and flexibility of the equipment.

[0010] Furthermore, the gripping mechanism is located above the machine base. The gripping mechanism includes a lifting frame and a moving base. The moving base is connected to the translation frame via a third horizontal drive component (such as a synchronous belt module or a linear motor) so that it can move back and forth on the translation frame in the horizontal direction (X-axis) to realize the transfer of workpieces between different workstations. The lifting frame is located on the side of the moving base close to the machine base. The lifting frame is connected to the moving base via a first linear drive component. The two ends of the lifting frame are symmetrically provided with first gripping frames, which are connected to the moving base via the first linear drive component (such as a cylinder or electric cylinder) and can be raised and lowered in the vertical direction (Z-axis) to grip or place workpieces. Each first gripping frame has a gripping block at each end along its length direction. The four gripping blocks work together to grip the IBC barrel frame.

[0011] Furthermore, a first electromagnet is provided at the middle position of the gripping block. Both ends of the gripping block have first cavities, each containing a piston. Each first cavity has an arc-shaped groove on the side furthest from the first gripping frame, and each arc-shaped groove has several adsorption holes on its wall. A connecting frame is provided inside the gripping block, connected to the piston. The end of the connecting frame near the first electromagnet is magnetic. When gripping the IBC bucket frame, the first linear drive unit drives the moving seat downwards until the arc-shaped groove on the gripping block aligns with the IBC. When the C-barrel frame is attached, the first electromagnet is energized. The first electromagnet magnetically attracts the IBC barrel frame on one hand and repels the connecting frame on the other, so that the piston is moved away from the adsorption hole. At this time, a negative pressure will be generated in the area between the piston and the adsorption hole. The IBC barrel frame is adsorbed and fixed through the adsorption hole on the arc groove. Through the above technical solution, the first electromagnet can generate magnetic attraction and negative pressure adsorption force at the same time, so as to form a double fixation for the IBC barrel frame, ensuring that the frame remains stable during the high-speed movement, lifting, or precise positioning of the gripping mechanism, and will not slip, shake, or fall off.

[0012] Furthermore, the gripping block is detachably connected to the first gripping frame, for example, by means of bolts. When the diameter of the round tube that makes up the IBC bucket frame changes, or when the gripping block is worn and needs to be replaced, the operator can easily and quickly remove the old gripping block and install a new gripping block that matches the diameter of the round tube that makes up the IBC bucket frame. This facilitates subsequent maintenance and quick replacement to adapt to IBC bucket frames of different specifications.

[0013] Furthermore, the lifting frame is symmetrically provided with second gripping frames at its other two ends. Each second gripping frame has a permanent magnet at both ends. The second gripping frames are connected to the lifting frame through a second linear drive. When the gripping block grabs the IBC bucket frame, the second gripping frame can retract towards the middle or expand outward under the drive of the second linear drive to adapt to frames of different widths. The permanent magnets are used to attract the middle part of the IBC bucket frame. Together with the gripping blocks at both ends, the entire IBC bucket frame is stably and evenly gripped, preventing the frame from deforming or shaking during transportation, and avoiding the IBC bucket frame from falling due to power outages or other phenomena.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Compared with the current IBC barrel frame welding device, the present invention is equipped with a first support mechanism and a second support mechanism. The first support mechanism includes a positioning seat, a connecting block, a rotating disk and a rotating drive component. The negative pressure adsorption component fastens the carrier component to the connecting block together, which avoids the carrier component from shifting or rotating due to external force when the IBC barrel frame is placed on the carrier component. This provides a reliable foundation for subsequent automated welding. At the same time, the rotating drive component drives the rotating disk and the connecting block to rotate, which drives the carrier component to rotate to the target position, improves the accuracy of position adjustment, reduces the trouble of manual operation, and significantly improves welding quality and production efficiency. 2. The rotary drive component of this invention has a self-locking function, ensuring that the IBC barrel frame is not accidentally deflected by external force during placement on the carrier and during welding, thus ensuring the accuracy of the weld position. In addition, when the rotary drive component malfunctions, the operator can pull the deflection shaft out of the first gear and manually rotate the deflection shaft. After the carrier reaches the target position, the deflection shaft is then inserted into the first gear and fixed by the clamping assembly. Through the joint cooperation of the deflection shaft, the clamping assembly, and the rotating disk, rapid emergency handling is achieved, which greatly shortens the equipment downtime, improves production efficiency and equipment maintainability, and ensures that this invention has high stability and emergency handling capabilities. 3. The gripping mechanism of this invention has dual fixing and adjustable functions. When gripping the welded IBC bucket frame, the first electromagnet generates magnetic attraction and negative pressure adsorption force to form a dual fixation of the IBC bucket frame, ensuring that the frame remains stable during high-speed movement, lifting, or precise positioning, and will not slip, shake, or fall off. At the same time, the gripping block is detachably connected to the first gripping frame, which is convenient for quick replacement to adapt to different specifications of IBC bucket frames. In addition, the other two ends of the lifting frame are also provided with second gripping frames, which are driven by the second linear drive component and use the magnetic force of permanent magnets to attract the middle part of the IBC bucket frame. Together with the gripping blocks at both ends, a stable and balanced gripping of the entire frame is achieved, preventing the frame from deforming or shaking during transportation, and further improving the reliability and safety of gripping.

[0017] 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.

[0018] Example: Figures 1-9As shown, the present invention provides a technical solution: an automatic positioning and rotary welding device for IBC barrel frames, comprising a base 1, a welding host 2, a gripping mechanism 3, and a translation frame 4. The base 1 has a U-shaped structure, providing an installation foundation for each component. Several first support mechanisms 5 are provided on the base 1 (the first support mechanisms 5 support the load-bearing components 7). A second support mechanism 6 is provided between two adjacent first support mechanisms 5 (the second support mechanism 6 supports the crossbeam). The welding host 2 is located on the side of each first support mechanism 5 and each second support mechanism 6. The welding host 2 is driven by a first horizontal drive component. Connected to the base 1, in order to achieve precise and stable welding of the bearing component 7 to the bottom of the IBC barrel frame, this device uses four first support mechanisms 5. The positions of the four first support mechanisms 5 correspond one-to-one with the four arc-shaped corners of the IBC barrel frame. The bearing component 7 is supported and positioned by the first support mechanisms 5. Compared with the support components currently used, the first support mechanism 5 in this device includes a positioning seat 52. The positioning seat 52 is provided with a connecting block 522, a rotating disk 523 and a rotating drive component 526. The rotating drive component 526 is connected to the rotating disk 523 through a transmission assembly. The connecting block 522 is located on the rotating disk 523. The end of disk 523 furthest from the rotating drive component 526, and the end of connecting block 522 furthest from disk 523, are provided with through holes. A negative pressure adsorption assembly is installed inside connecting block 522. Before welding, the carrier component 7 is placed on the positioning seat 52, and then the negative pressure adsorption assembly is activated. The carrier component 7 is secured to connecting block 522 through the negative pressure adsorption assembly and the through hole in connecting block 522. This prevents the carrier component 7 from shifting or rotating relative to connecting block 522 due to collisions or other reasons when the IBC barrel frame is placed on it, thus providing a reliable foundation for subsequent automated welding processes. Finally... When placing the carrier 7 onto the positioning seat 52, the operator often needs to manually adjust the position of the carrier 7 so that the midpoint of the arc of the carrier 7 is aligned with the midpoint of the arc at the end of the positioning seat 52, thereby ensuring that the relative position of the carrier 7 and the arc edge of the IBC barrel frame meets the requirements. In this invention, when the carrier 7 is fastened together with the connecting block 522, the rotating drive 526 can drive the rotating disk 523 and the connecting block 522 to rotate, thereby driving the carrier 7 to rotate to the target position. Through the above technical solution, on the one hand, the accuracy of position adjustment is improved, and on the other hand, the trouble of manual operation is reduced.

[0019] like Figures 3-6As shown, a deflection shaft 521 is provided at the middle position of the rotating disk 523. A flat key is provided on the rotating disk 523, and a groove is provided on the deflection shaft 521. The rotating disk 523 is connected to the deflection shaft 521 through a keyway fit. The deflection shaft 521 has an axial movement function. The transmission assembly includes a first gear 524 and a second gear 525. The first gear 524 is connected to the rotating disk 523, and the second gear 525 is connected to the rotary drive component 526. A clamping assembly is provided at the middle position of the first gear 524. One end of the deflection shaft 521 is located in the clamping assembly, and the other end of the deflection shaft 521 extends out of the positioning seat 52. The clamping assembly fixes the deflection shaft 521 and the first gear 524 together. In this invention, the rotary drive component 526 has a self-locking function. When the rotary drive component 526 is working normally, the operator can drive the rotating disk 523 and the connecting block 522 to rotate through the rotary drive component 526, thereby driving the carrier component. 7. Rotation: The self-locking property of the rotation drive 526 prevents the IBC bucket frame from deflecting when placed onto the carrier 7. If the rotation drive 526 malfunctions, the operator can pull the deflection shaft 521 out of the first gear 524 and manually rotate it. At this time, the rotating disk 523 and the connecting block 522 will continue to drive the carrier 7 to rotate. When the carrier 7 reaches the target position, the deflection shaft 521 is reinserted into the first gear 524. The clamping assembly and the deflection shaft 521 work together to fix the first gear 524 and the rotating disk 523 together again. Through the above technical solution, the present invention can ensure that the carrier 7 will not deflect unexpectedly due to external force when the IBC bucket frame is placed onto the carrier 7 and during welding, thus ensuring the accurate position of the weld. On the other hand, it can achieve rapid emergency handling, significantly shorten equipment downtime, and improve production efficiency and equipment maintainability.

[0020] like Figures 6-7 As shown, the clamping assembly includes several clamping blocks 5241. Each clamping block 5241 is connected to the first gear 524 via a compression spring, allowing the clamping block 5241 to move radially relative to the center of the first gear 524. When the deflection shaft 521 moves out of the clamping blocks 5241, the first gear 524 is slidably connected to the rotating disk 523. When the deflection shaft 521 is inserted into the clamping blocks 5241, the clamping assembly can fix the deflection shaft 521 and the first gear 524 together, thereby ensuring that the first gear 524 and the rotating disk 523 rotate synchronously. Finally, each clamping block 5241 in this invention has a chamfer at one end near the center line of the first gear 524 to serve as a guide. In addition, the width of each clamping block 5241 is greater than the width of the groove on the deflection shaft 521 to provide a stable and reliable clamping force and ensure the transmission of torque.

[0021] like Figure 5As shown, a second cavity 5221 is provided at one end of the connecting block 522 near the through hole. The negative pressure adsorption assembly includes a movable frame 5222 and a second electromagnet 5223. One end of the movable frame 5222 is located in the second cavity 5221, and the other end of the movable frame 5222 is located near the second electromagnet 5223. When the carrier 7 is placed on the positioning seat 52, the second electromagnet 5223 is energized to generate magnetic force, which attracts the movable frame 5222 to move away from the through hole, thereby expanding the volume between the second cavity 5221 and the through hole. This creates a negative pressure between the second cavity 5221 and the through hole, thus firmly adsorbing the carrier 7 onto the connecting block 522. This facilitates the automatic positioning and rotation of the carrier 7 by the rotation drive 526, and also prevents the carrier 7 from shifting or rotating due to external force when the IBC bucket frame is placed on it.

[0022] like Figure 3 As shown, to accommodate IBC barrel frames of different lengths or specifications, the first support mechanism 5 of this invention further includes a mounting base 51 and a second horizontal drive component. The mounting base 51 is directly fixed to the machine base 1, and the positioning seat 52 is slidably connected to the mounting base 51 via the second horizontal drive component. By controlling the extension and retraction of the second horizontal drive component, the position of the positioning seat 52 relative to the mounting base 51 can be precisely adjusted, thereby changing the span between adjacent first support mechanisms 5. This allows the equipment to be compatible with the production of IBC barrel frames of different sizes, improving the versatility and flexibility of the equipment.

[0023] like Figures 1-8 As shown, the gripping mechanism 3 is located above the base 1. The gripping mechanism 3 includes a lifting frame 31 and a moving seat 34. The moving seat 34 is connected to the translation frame 4 via a third horizontal drive component (such as a synchronous belt module or a linear motor) so that it can move back and forth on the translation frame 4 in the horizontal direction (X-axis) to realize the transfer of workpieces between different workstations. The lifting frame 31 is located on the side of the moving seat 34 close to the base 1. The lifting frame 31 is connected to the moving seat 34 via a first linear drive component. The two ends of the lifting frame 31 are symmetrically provided with first gripping frames 32, which are connected to the moving seat 34 via a first linear drive component (such as a cylinder or electric cylinder) and can be raised and lowered in the vertical direction (Z-axis) to grip or place workpieces. Each first gripping frame 32 is provided with a gripping block 321 at each end along its length direction. The four gripping blocks 321 work together to grip the IBC barrel frame.

[0024] like Figure 9As shown, a first electromagnet 3211 is located at the middle of the gripping block 321. Both ends of the gripping block 321 have first cavities 3213, each containing a piston 3214. Each first cavity 3213 has an arc-shaped groove on its side away from the first gripping frame 32, and several suction holes are provided on the wall of each arc-shaped groove. A connecting frame 3212 is located inside the gripping block 321, connected to the piston 3214. The end of the connecting frame 3212 near the first electromagnet 3211 is magnetic. When gripping the IBC bucket frame, the first linear drive unit drives the moving seat 34 to move downwards until the gripping block 321... The arc-shaped groove on 21 fits into the IBC bucket frame. Then, the first electromagnet 3211 is energized. The first electromagnet 3211 magnetically attracts the IBC bucket frame on one hand and repels the connecting frame 3212 on the other hand, so that the piston 3214 is moved away from the adsorption hole. At this time, a negative pressure will be generated in the area between the piston 3214 and the adsorption hole. The IBC bucket frame is adsorbed and fixed through the adsorption hole on the arc-shaped groove. Through the above technical solution, the first electromagnet 3211 can generate magnetic attraction and negative pressure adsorption force at the same time, so as to form a double fixation for the IBC bucket frame, ensuring that the frame remains stable during the high-speed movement, lifting or precise positioning of the gripping mechanism 3, and will not slip, shake or fall off.

[0025] like Figure 8 As shown, the gripping block 321 is detachably connected to the first gripping frame 32. For example, it can be connected by bolts. When the diameter of the round tube that makes up the IBC bucket frame changes, or when the gripping block 321 is worn and needs to be replaced, the operator can easily and quickly remove the old gripping block 321 and install a new gripping block 321 that matches the diameter of the round tube that makes up the IBC bucket frame. This facilitates subsequent maintenance and quick replacement to adapt to IBC bucket frames of different specifications.

[0026] like Figure 8 As shown, the other two ends of the lifting frame 31 are symmetrically provided with second gripping frames 33. Each second gripping frame 33 is provided with permanent magnets 331 at both ends. The second gripping frames 33 are connected to the lifting frame 31 through the second linear drive. When the gripping block 321 grips the IBC bucket frame, the second gripping frame 33 can retract towards the middle or expand outward under the drive of the second linear drive to adapt to frames of different widths. The magnetic force of the permanent magnets 331 is used to attract the middle part of the IBC bucket frame. With the gripping blocks 321 at both ends, the entire IBC bucket frame is stably and evenly gripped, preventing the frame from deforming or shaking during transportation, and avoiding the IBC bucket frame from falling due to power failure or other phenomena.

[0027] The working principle of this invention is as follows: Before welding, the carrier 7 is placed on the positioning seat 52. Then, the second electromagnet 5223 is energized to generate magnetic force, attracting the movable frame 5222 to move away from the through hole. This creates a negative pressure between the second cavity 5221 and the through hole, firmly adsorbing the carrier 7 onto the connecting block 522. Next, the rotary drive 526 drives the rotating disk 523 and the connecting block 522 to rotate, thereby rotating the carrier 7 to the target position. If the rotary drive 526 malfunctions and cannot work, the operator can pull the deflection shaft 521 out of the first gear 524 and manually rotate the deflection shaft 521. At this time, the rotating disk 523 and the connecting block 522 will continue to drive the carrier 7 to rotate. When the carrier 7 reaches the target position, the deflection shaft 521 is reinserted into the first gear 524 and clamped... The cooperation of the holding component and the deflection shaft 521 fixes the first gear 524 and the rotating disk 523 together again to prevent the carrier 7 from being accidentally deflected due to external force, thereby ensuring the accurate position of the weld. When the carrier 7 is stable and the IBC barrel frame is placed on the carrier 7, the welding host 2 welds the carrier 7 to the bottom of the IBC barrel frame. When the welding is finished, the first linear drive drives the moving seat 34 to move down until the arc groove on the gripping block 321 fits with the IBC barrel frame. Then the first electromagnet 3211 is energized. The first electromagnet 3211 magnetically attracts the IBC barrel frame on the one hand and repels the connecting frame 3212 on the other hand, so that the piston 3214 is away from the adsorption hole. At this time, the IBC barrel frame is adsorbed and fixed through the adsorption hole on the arc groove. The third horizontal drive moves the IBC barrel frame to the subsequent station.
