Description

Technical Field

[0001] This invention relates to the field of packaging box welding technology, specifically to an intelligent welding device for logistics packaging boxes. Background Technology

[0002] With the rapid development of the logistics industry, the demand for logistics packaging boxes, as the core carrier for cargo storage and transportation, continues to rise, placing higher demands on the production efficiency, structural strength, and processing precision of these boxes. In the manufacturing process of logistics packaging boxes, welding is a crucial step in ensuring the structural stability of the box, directly affecting its load-bearing capacity and service life.

[0003] Currently, most existing equipment operates in a single-station mode, meaning that the welding of one packaging box panel must be completed before the next one can be loaded. This severely restricts production efficiency and makes it difficult to adapt to large-scale continuous manufacturing scenarios. Furthermore, most small and medium-sized logistics packaging box manufacturers still use traditional manual or semi-automated welding methods. These methods rely on operators to manually complete processes such as positioning and flipping the packaging box panels, which is not only labor-intensive and costly but also susceptible to variations in operator skill levels, leading to poor weld quality stability, insufficient weld flatness, and uneven weld strength – problems that frequently occur and cannot meet the demands of large-scale, standardized production. Simultaneously, the welding process generates welding fumes, arc radiation, and metal spatter, which not only severely pollute the working environment but also pose a significant health hazard to operators, failing to meet the green, environmentally friendly, and safe production requirements of modern industrial production.

[0004] Therefore, we propose an intelligent welding device for logistics packaging boxes to solve the problems mentioned above. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: The purpose of this invention is to provide an intelligent welding device for logistics packaging boxes to solve the problems currently existing in the market as mentioned in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: an intelligent welding device for logistics packaging boxes, including a support base, on which a rotating frame that can rotate around a horizontal axis is mounted via bearings, a chain conveying mechanism is provided below the rotating frame, and a flipping mechanism is installed at both the upper and lower ends of the rotating frame, the output end of the flipping mechanism is connected to a work frame, and several sets of clamping mechanisms are installed on the work frame. Welding protective covers are slidably mounted on both the upper and lower ends of the rotating frame. A driving mechanism is installed on the side of the rotating frame. The driving mechanism is used to drive the two welding protective covers to move synchronously. A set of suction components is installed on both sides of each welding protective cover. A lifting module is installed below the support base. When the welding protective cover below moves downward, the lifting module lifts the material on the chain conveyor mechanism upward into the work frame below. The material includes the mounting frame and the packaging box plate to be welded, which is arranged parallel to the mounting frame. The packaging box plate to be welded is positioned on the mounting frame by the positioning fixture. After being lifted, it is fixed by the clamping mechanism. After being flipped to the welding station, it is welded by the welding mechanism.

[0007] Furthermore, the clamping mechanism includes a clamping cylinder, a movable frame, a fixed plate, and two sets of auxiliary clamping arms; The clamping cylinder is mounted on the work frame, and its output end is fixedly connected to the movable frame. A guide column is fixed on the movable frame, and the guide column is slidably fitted inside the work frame to achieve guidance. The movable frame is equipped with an elastic telescopic component, and the movable end of the elastic telescopic component is fixedly connected to the fixed plate. A rubber pad is provided on the side of the fixed plate away from the clamping cylinder. The movable frame is also equipped with two sets of auxiliary clamping arms, and the two sets of auxiliary clamping arms are respectively connected to the upper and lower sides of the fixed plate by a transmission component. During the displacement of the fixed plate, the auxiliary clamping arms are rotated through the transmission component.

[0008] The above technical solution enables the positioning fixture on the mounting frame to fix the packaging box plate to be welded, and then the chain conveyor mechanism to transport it to the preset station below the support base. When the material is inside the working frame, the clamping cylinder is activated, which drives the fixing plate to apply the main clamping force to the mounting frame, and at the same time drives the auxiliary clamping arm to rotate to apply the secondary clamping force.

[0009] Furthermore, the auxiliary clamping arm includes a swing arm shaft and a roller. One end of the swing arm shaft is rotatably mounted on the movable frame, and the other end of the swing arm shaft is rotatably connected to the roller. The transmission component includes a rack and a gear. The rack is fixed to the side of the fixed plate, and the gear is fixedly sleeved on the rotating shaft between the swing arm shaft and the movable frame. The rack and the gear mesh with each other.

[0010] Through the above technical solution, as the fixing plate continuously approaches the material, the cooperation between gear one and rack one can drive the swing arm shaft to rotate, thereby driving the roller to press against the end of the mounting frame, improving the clamping stability.

[0011] Furthermore, the drive mechanism includes an input drive shaft, an intermediate transmission shaft, and a turntable; The input drive shaft, intermediate transmission shaft, and turntable are all mounted on the side of the rotating frame via bearings, and a transmission belt assembly is installed between the input drive shaft and the intermediate transmission shaft. A drive component is installed between the intermediate drive shaft and the turntable, and the intermediate drive shaft drives the turntable to rotate intermittently through the drive component. The turntable is hinged to both of the two welding protective covers by connecting rods.

[0012] The above technical solution enables the welding protective cover to slide on the rotating frame via the connecting rod after the turntable rotates.

[0013] Furthermore, the driving component includes a dial and a grooved wheel; The dial is fixed to the end of the intermediate drive shaft, and a drive pin and a locking arc plate are installed on the end face of the dial. The grooved wheel is sleeved and fixed on the outer side of the shaft end of the turntable, and the side of the grooved wheel is provided with a locking groove and a radial groove. When the dial rotates, the drive pin enters the radial groove to drive the groove wheel and the turntable to rotate, while the locking arc plate engages with the locking groove to restrict the free rotation of the turntable during the non-drive phase.

[0014] The above technical solution enables the input drive shaft to rotate the intermediate drive shaft via the transmission belt assembly, which in turn drives the dial to rotate, thereby controlling the rotation or stopping of the grooved wheel.

[0015] Furthermore, a position touch switch mechanism is installed between the side of the dial and the rotating frame. The position touch switch mechanism includes a mounting bracket, a stationary contact, and a moving contact. The mounting bracket is fixed on the rotating frame, and the stationary contact is mounted on the mounting bracket; The moving contact is fixed to the side of the dial; When the dial is rotated to the preset position, the moving contact contacts the stationary contact, thereby starting the suction machine connected to the suction hood in the suction assembly.

[0016] The above technical solution enables the suction machine to be turned on and suction to be performed when the moving contact comes into contact with the stationary contact.

[0017] Furthermore, the suction assembly includes a movable rod and multiple suction shields; The movable rod is fixedly installed inside the welding protective cover, and multiple suction hoods are fixedly sleeved on the outside of the movable rod at equal intervals, with each suction hood connected to the input end of the suction machine through a pipeline.

[0018] The above technical solution enables the suction hood to collect and treat the fumes generated during the welding process after the suction machine is started.

[0019] Furthermore, the lifting module includes a guide column, a bracket, a lifting support plate, and a transmission assembly; The guide column is fixed on the support base, and the bracket is slidably sleeved on the outside of the guide column in the vertical direction; The lifting plate is fixed to the upper end of the bracket and is used to lift the material on the chain conveyor mechanism upward. A transmission assembly is installed on the side of the bracket to drive the bracket to move up and down along the guide column.

[0020] The above technical solution allows the lifting pallet to move upward, lifting the material on the chain conveyor mechanism and causing it to enter the work frame.

[0021] Furthermore, the transmission assembly includes a toothed plate, a transmission component two, and two racks two; The toothed plate is fixed to the side of the bracket; The two racks are respectively fixed to the sides of the two welded protective covers; The transmission component 2 is rotatably mounted on the support base. The transmission component 2 includes gear 2 and gear 3. Gear 2 and gear 3 are both mounted on the support base through bearings. One side of gear 2 and gear 3 mesh with each other, and the other side of gear 2 is correspondingly arranged with rack 2. Gear 4 is fixed at both ends of gear 3, and each gear 4 meshes with a corresponding toothed plate. When the welding protective cover located below is raised or lowered, the transmission chain of rack two, gear two, gear three, and gear four drives the toothed plate and the lifting support plate on the bracket to rise and fall synchronously.

[0022] Through the above technical solution, the welding protective cover can move the lifting plate to the appropriate position during the displacement process under the action of the transmission component.

[0023] 3. Beneficial effects: Compared with the prior art, the intelligent welding device for logistics packaging boxes provided by this invention integrates functional units such as a chain conveyor mechanism, a lifting module, a clamping mechanism, a flipping mechanism, and a suction component. It completes the entire process from automatic material feeding, precise positioning, stable clamping, and posture flipping to welding fume treatment. Furthermore, it enables continuous alternating operation between upper and lower workstations, resulting in high production efficiency. The specific details are as follows: (1) This invention integrates functional units such as chain conveyor, lifting module, clamping mechanism, flipping mechanism and suction component to complete automatic material feeding, precise positioning, stable clamping, posture flipping to welding fume treatment. In particular, through the linkage design of lifting tray and welding protective cover, the loading and unloading and welding preparation are seamlessly connected, effectively shortening non-production time. It is suitable for high-speed continuous production lines. At the same time, during the loading and unloading process, the packaging box plate located in the upper work frame can be welded simultaneously, further improving processing efficiency. (2) The clamping mechanism adopts a main clamping + auxiliary pressure composite clamping method. The clamping cylinder drives the movable frame to drive the fixed plate to apply the main clamping force to the side wall of the mounting frame. At the same time, the displacement of the fixed plate is assisted by the transmission component to rotate the clamping arm around the swing arm axis, so that the roller automatically presses the end face of the mounting frame, improves the clamping stability, and improves the weld consistency and product qualification rate. (3) The upper and lower sets of welding protective covers rise and fall synchronously under the control of the drive mechanism, surround the welding area, block strong arc light, metal spatter and high temperature radiation, and protect the safety of surrounding equipment and personnel. At the same time, multiple suction covers in the suction assembly are distributed at equal intervals on the movable rod, and the suction machine sucks up welding fumes after it starts. (4) When the welding protective cover is raised and lowered, the rack two fixed on its side drives the transmission component two and the gear four at both ends, thereby driving the toothed plate fixed to the bracket to move synchronously, realizing the precise raising and lowering of the lifting plate along the guide column. This pure mechanical transmission chain does not require additional motors or pneumatic components, which not only saves energy and reduces manufacturing costs, but also avoids the risk of electrical control delay or air leakage, and significantly enhances system stability. (5) The intermediate drive shaft drives the dial to rotate, and the drive pin on it periodically inserts into the radial groove of the groove wheel, driving the turntable to rotate intermittently, and converting it into the lifting action of the welding protective cover through the connecting rod. In the non-working area, the locking arc plate and the locking groove are tightly fitted to achieve mechanical self-locking, avoiding the risk of shaking or malfunction of the welding protective cover, and ensuring high repeatability positioning accuracy of loading, unloading and welding stations. (6) When the dial is rotated to the preset position for welding work, the moving contact on its side contacts the stationary contact fixed on the mounting bracket, automatically connects the circuit, starts the drive motor of the suction assembly, and the suction hood is connected to the suction machine through the pipeline to suck up the smoke and exhaust gas generated during the welding process in real time, avoiding the spread of pollutants. This design can avoid the suction system from running idle for a long time and only operate during the welding stage, which can extend the equipment life and reduce energy consumption.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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. Example

[0027] Please see Figure 1-11This invention provides a technical solution: an intelligent welding device for logistics packaging boxes, including a support base 1. A rotating frame 3, which can rotate around a horizontal axis, is mounted on the support base 1 via bearings. A chain conveyor mechanism 2 is arranged below the rotating frame 3. A flipping mechanism 4 is installed at both the upper and lower ends of the rotating frame 3. The output end of the flipping mechanism 4 is connected to a work frame 5. Several sets of clamping mechanisms 6 are installed on the work frame 5. The clamping mechanism 6 includes a clamping cylinder 61, a movable frame 62, a fixed plate 63, and two sets of auxiliary clamping arms 65. The clamping cylinder 61 is installed on the work frame 5, and its output end is fixedly connected to the movable frame 62. A guide post 67 is fixed on the movable frame 62, and the guide post 67 slides within the work frame 5 to achieve guidance. An elastic telescopic member 64 is installed on the movable frame 62, and the movable end of the elastic telescopic member 64 is connected to the fixed plate 62. A fixed plate 63 is fixedly connected, and a rubber pad is provided on the side of the fixed plate 63 away from the clamping cylinder 61; two sets of auxiliary clamping arms 65 are also installed on the movable frame 62, and the two sets of auxiliary clamping arms 65 are respectively connected to the upper and lower sides of the fixed plate 63 by transmission components 66. During the displacement of the fixed plate 63, the auxiliary clamping arms 65 are rotated through the transmission components 66; the auxiliary clamping arms 65 include a swing arm shaft 651 and a roller 652. One end of the swing arm shaft 651 is rotatably mounted on the movable frame 62, and the other end of the swing arm shaft 651 is rotatably connected to the roller 652; the transmission component 66 includes a rack 661 and a gear 662. The rack 661 is fixed to the side of the fixed plate 63, and the gear 662 is fixedly sleeved on the rotating shaft between the swing arm shaft 651 and the movable frame 62. The rack 661 and the gear 662 mesh with each other; The logistics packaging box is an open steel box consisting of a bottom plate and four side plates vertically set on the bottom plate. The bottom plate and side plates have the same structure, consisting of an outer frame and inner horizontal and vertical bars. The ends of the horizontal and vertical bars are welded to the frame. This invention is for welding the bottom plate or side plates of the logistics packaging box. Once one side of the packaging box is welded, the flipping mechanism 4 located above is activated, causing the corresponding work frame 5 to flip 180°. The flipping mechanism 4 can use an electric push rod to drive the rack and gear to mesh, and achieve precise flipping through the work frame 5 connected to the end of the gear, so that the welded side faces down and the unwelded side faces up, in order to carry out the welding operation on the other side. Meanwhile, after the packaging box panels in the upper work frame 5 have completed double-sided welding, the motor built into the support base 1 can be started to drive the rotating frame 3 to rotate 180° as a whole, so that the packaged box panels that have been welded can be transferred to the lower work station for unloading. At the same time, the packaged box panels that have been loaded and clamped at the bottom can be flipped to the upper welding work station, realizing the alternating continuous operation of the upper and lower work stations, which significantly improves the production cycle and equipment utilization rate. Welding protective covers 7 are slidably mounted on both the upper and lower ends of the rotating frame 3. A drive mechanism 8 is mounted on the side of the rotating frame 3. The drive mechanism 8 is used to drive the two welding protective covers 7 to move synchronously. A set of suction components 10 is mounted on both sides of each welding protective cover 7. The drive mechanism 8 includes an input drive shaft 81, an intermediate transmission shaft 82, and a turntable 83. The input drive shaft 81, the intermediate transmission shaft 82, and the turntable 83 are all mounted on the side of the rotating frame 3 through bearings, and a transmission belt assembly is installed between the input drive shaft 81 and the intermediate transmission shaft 82. A drive component 84 is installed between the intermediate transmission shaft 82 and the turntable 83. The intermediate transmission shaft 82 drives the turntable 83 through the drive component 84. Intermittent rotation; connecting rods 85 are hinged between turntable 83 and two welding protective covers 7; driving component 84 includes dial 841 and grooved wheel 844; dial 841 is fixed to the shaft end of intermediate transmission shaft 82, and driving pin 842 and locking arc plate 843 are installed on the end face of dial 841; grooved wheel 844 is sleeved and fixed on the outer side of the shaft end of turntable 83, and locking groove 845 and radial groove 846 are opened on the side of grooved wheel 844; when dial 841 rotates, driving pin 842 enters radial groove 846 to drive grooved wheel 844 and turntable 83 to rotate, while locking arc plate 843 fits with locking groove 845 to restrict free rotation of turntable 83 in non-driving stage; During the material conveying stage, the packaging box to be welded is first fixed on the mounting frame, and then conveyed by the chain conveyor 2 to the preset work position below the support base 1. At this time, the drive mechanism 8 is started, and its internal input drive shaft 81 drives the intermediate drive shaft 82 to rotate through the transmission belt assembly, which in turn drives the dial 841 to rotate. The drive pin 842 on the dial 841 enters the radial groove 846 of the groove wheel 844, causing the groove wheel 844 and the turntable 83 to rotate intermittently. The turntable 83 drives the two welding protective covers 7 to move on the rotating frame 3 through the connecting rod 85. After the welding protective cover 7 located above is raised, it blocks strong arc light, metal spatter and high temperature radiation. At the same time, the suction component 10 installed inside it is in place, so that multiple suction covers 102 are aligned with the weld seam area of ​​the packaging box, preparing for subsequent efficient suction of welding fumes. A position touch switch mechanism 9 is installed between the side of the dial 841 and the rotating frame 3. The position touch switch mechanism 9 includes a mounting bracket 91, a stationary contact 92, and a moving contact 93. The mounting bracket 91 is fixed on the rotating frame 3, and the stationary contact 92 is mounted on the mounting bracket 91. The moving contact 93 is fixed on the side of the dial 841. When the dial 841 rotates to a preset position, the moving contact 93 contacts the stationary contact 92, thereby activating the suction machine connected to the suction cover 102 in the suction assembly 10. The suction assembly 10 includes a movable rod 101 and multiple suction covers 102. The movable rod 101 is fixedly installed inside the welding protective cover 7, and multiple suction covers 102 are fixedly sleeved on the outside of the movable rod 101 at equal intervals. Each suction cover 102 is connected to the input end of the suction machine through a pipeline. When the dial 841 is rotated to the preset position for welding, the moving contact 93 on its side contacts the stationary contact 92 fixed on the mounting bracket 91, automatically connecting the circuit and starting the drive motor of the suction assembly 10. The suction hood 102 is connected to the suction machine through the pipeline, and the smoke and exhaust gas generated during the welding process are sucked in real time to avoid the spread of pollutants. At the same time, the suction system can be prevented from running idle for a long time, and it only runs during the welding stage, which not only extends the equipment life but also reduces energy consumption. A lifting module 11 is installed below the support base 1. When the welding protective cover 7 located below moves downward, the lifting module 11 lifts the material on the chain conveyor mechanism 2 upward into the work frame 5 below. The material includes the mounting frame and the packaging box plate to be welded, which is arranged parallel to the mounting frame. The packaging box plate to be welded is positioned on the mounting frame by the positioning clamp, and after being lifted, it is fixed by the clamping mechanism 6. After being flipped to the welding station, it is welded by the welding mechanism. The lifting module 11 includes a guide column 111, a bracket 112, a lifting plate 113, and a transmission assembly. The guide column 111 is fixed on the support base 1, and the bracket 112 is slidably sleeved on the outside of the guide column 111 in the vertical direction. The lifting plate 113 is fixed to the upper end of the bracket 112 and is used to lift the material on the chain conveyor mechanism 2 upward. A transmission assembly is installed on the side of the bracket 112 to drive the bracket 112 to move up and down along the guide column 111. The transmission assembly includes gears. Plate 114, transmission component 2 115, and two racks 2 116; the rack 114 is fixed to the side of the bracket 112; the two racks 2 116 are respectively fixed to the sides of the two welded protective covers 7; the transmission component 2 115 is rotatably mounted on the support base 1, and the transmission component 2 115 includes gear 2 1151 and gear 3 1152, both of which are mounted on the support base 1 via bearings, and one side of gear 2 1151 and gear 3 115... 2. The gears mesh with each other, and the other side of the gear 2 1151 is correspondingly set with the rack 2 116. Both ends of the gear 3 1152 are fixed with gear 4 1153, and each gear 4 1153 meshes with the corresponding gear plate 114. When the welding protective cover 7 located below is raised or lowered, the gear plate 114 and the lifting support plate 113 on the bracket 112 are raised or lowered synchronously through the transmission chain of rack 2 116, gear 2 1151, gear 3 1152 and gear 4 1153. As the welding protective cover 7 located below moves downward, the rack 2 116 on its side drives the gear 2 1151 in the transmission component 2 115 to rotate. The gear 2 1151 meshes with the drive gear 3 1152 and the gear 4 1153 at both ends to rotate synchronously. The gear 4 1153 meshes with the toothed plate 114 on the side of the bracket 112, causing the bracket 112 to slide upward along the guide column 111. The lifting plate 113 fixed on the upper end of the bracket 112 rises accordingly, lifting the material on the chain conveyor mechanism 2 upward into the working frame 5 below, completing the material loading and positioning. The clamping mechanism 6 can then be used to clamp and fix the material. After the material enters the work frame 5, the clamping mechanism 6 is automatically activated. The output end of the clamping cylinder 61 pushes the movable frame 62 to move along the guide column 67 toward the material. The elastic telescopic component 64 on the movable frame 62 drives the fixed plate 63 to fit against the side of the mounting frame. The rubber pad at its end achieves flexible clamping to avoid damage to the workpiece surface. During the displacement of the fixed plate 63, the rack 661 fixed on its side meshes with the gear 662 installed on the swing arm shaft 651, thereby driving the two sets of auxiliary clamping arms 65 to rotate synchronously around the swing arm shaft 651, so that the roller 652 presses against the upper and lower end faces of the mounting frame, forming an all-round clamping structure of lateral main clamping and end face auxiliary pressure, improving clamping stability.

[0028] Working principle: When using this intelligent welding device for logistics packaging boxes, such as Figure 1-11 As shown, the packaging box to be welded is first fixed on the mounting frame, and then conveyed to the preset work position below the support base 1 by the chain conveyor mechanism 2. Then, the drive mechanism 8 is started to drive the upper and lower welding protective covers 7 to move synchronously. The lower welding protective cover 7 is lifted by the transmission component and the lifting plate 113 is raised to accurately lift the material on the chain conveyor mechanism 2 into the lower work frame 5, completing automatic feeding and positioning. Then, the clamping mechanism 6 is activated to reliably clamp the material. Subsequently, the motor-driven rotating frame 3 inside the support base 1 rotates 180°, transferring the clamped material to the upper workstation. At this time, the drive mechanism 8 is activated again, causing the two welding protective covers 7 to move. The upper welding protective cover 7 performs protective work, and the suction component 10 is activated to collect smoke and dust. At the same time, the lower welding protective cover 7 performs the loading and positioning operation for the next piece of material according to the same principle, realizing parallel operation of the upper and lower workstations and improving processing efficiency. After the upper packaging box panel is in the welding position, welding can be carried out on one side. After the welding of this side is completed, the flipping mechanism 4 is activated, which drives the work frame 5 and the clamped material to flip 180°, so that the welded side is facing down and the unwelded side is facing up, thereby completing the welding of the other side. Finally, the all-round, double-sided continuous welding of the packaging box panel joint is achieved, so as to facilitate the subsequent assembly of the packaging box.
