[0001] This invention relates to the field of parts picking technology, and more specifically to an intelligent picking system for automotive parts. Background Technology

[0002] The assembly of automobiles requires a large number of parts and accessories, necessitating frequent retrieval by staff. Due to the complexity of these parts and the commonality of some components, errors are easily made during retrieval. Furthermore, the need for staff to manually select defective parts and accessories when some are found to be defective is a significant inconvenience. Therefore, designing an intelligent picking station for automotive parts is crucial to improving picking efficiency and preventing human errors. Summary of the Invention

[0003] To address the aforementioned problems, this invention designs an intelligent picking system for automotive parts. Through a docking system, pallets or boxes on pallets at any location on the shelf can be transported to a sorting table, and the sorting table then transports the pallets or boxes to designated locations, thereby completing the automatic picking of parts. This not only greatly improves picking efficiency but also effectively avoids picking errors.

[0004] To solve the above-mentioned technical problems, the present invention provides an intelligent picking system for automotive parts, characterized in that: it includes a sorting table, a docking system, shelves, and pallets. Two shelves are arranged side-by-side, each shelf holding several pallets from top to bottom, and each pallet holding several material boxes. Two docking systems are also arranged side-by-side, each located directly in front of one of the two shelves. The sorting table is located directly in front of the two docking systems. The front of each docking system facing the sorting table has a discharge port, and the back of each docking system facing the shelves has a retrieval port. The docking system contains a material box gripping robotic arm and a pallet hooking robotic arm. The docking system uses the material box gripping robotic arm and the pallet hooking robotic arm to transport the material boxes on the pallets and the pallets on the shelves to the sorting table. The sorting table is L-shaped, and an empty material box conveying device is located directly below its front end.

[0005] Furthermore, the docking system has two support frames inside, and several rollers are arranged sequentially from front to right inside the support frames. The two support frames are connected to the material box gripping robot arm and the pallet hooking robot arm respectively through telescopic mechanisms. The support frames are also connected to the translation mechanism and the height adjustment mechanism respectively.

[0006] Furthermore: the sorting table includes two side-by-side supports, two lifting supports, a conveyor belt conveying mechanism, and left and right horizontal conveying mechanisms. The two lifting supports are connected to the two supports through the lifting mechanism. The upper end of the supports is U-shaped. An auxiliary worktable is provided on the convex surface of the two supports near one end, and a worktable is also provided on the convex surface of the two supports away from each other. A protective cover is fixed on the front end of the two supports. Four partition frames are arranged from left to right between the auxiliary worktable and the worktable on the same support. The four partition frames are fixed on the lifting supports within the same support. The left and right horizontal conveying mechanisms are installed on the four partition frames on the same support. Three independent conveyor belt conveying mechanisms are arranged from left to right on the same support. A conveyor belt conveying mechanism is arranged between each two adjacent partition frames. The upper end of the left and right horizontal conveying mechanisms is flush with the upper surface of the auxiliary worktable and the worktable by the lifting mechanism.

[0007] Furthermore: the conveyor belt conveying mechanism consists of a conveyor belt, side covers, a drive roller, a driven roller, and a conveyor motor. Two side covers are arranged opposite each other between two adjacent partition frames on the same support. The two side covers are fixed on the same support. The drive roller and the driven roller are respectively installed between the front and rear ends of the two side covers. The drive roller is connected to a conveyor motor fixed inside one of the side covers. The conveyor belt wraps around the outside of the drive roller and the driven roller and conveys the material through the rotation of the drive roller and the driven roller.

[0008] Furthermore: the lifting mechanism includes a servo motor, a reducer, a bevel gear transmission assembly, and a worm gear jack. Both lifting brackets are connected to the brackets via the worm gear jacks. The servo motor is fixed to a bracket via a motor mounting base. The reducer is connected to the servo motor and its output shaft extends from both sides. The output shafts on both sides are respectively connected to a worm gear jack in one of the brackets via the bevel gear transmission assembly.

[0009] Furthermore: the left and right horizontal conveying mechanism includes a conveying roller, a driven sprocket, a driving sprocket, and a chain. Each of the four partitions on the same support is provided with a mounting groove that matches the conveying roller. The conveying roller is embedded and rotatably connected in the mounting groove on the partition. The upper end of the conveying roller extends out of the mounting groove. One of the four conveying rollers on the same lifting frame is an electric roller, which rotates in the mounting groove by itself and its output shaft extends out of the mounting groove. The output shaft of the electric roller extending out of the mounting groove is equipped with a driving sprocket. The other three conveying rollers are rotatably connected in the mounting groove through a rotating shaft. One end of the rotating shaft also extends out of the mounting groove and is equipped with a driven sprocket. The driving sprocket is connected to the other three driven sprockets through a chain.

[0010] Furthermore, an auxiliary support is provided on the outer side of each of the two supports at opposite ends. The auxiliary support is close to the support and has a touch screen on its top. The touch screen is electrically connected to a controller installed in the auxiliary support. The auxiliary support also has a maintenance port and a storage box on its side wall.

[0011] Furthermore: the pallet includes a pallet body, a base, side panels, partitions, and limiting blocks. The pallet body is mounted on the base. There are two side panels and two partitions. The two side panels are fixed to the top of the left and right ends of the pallet body, respectively. The two partitions are fixed to the pallet body between the two side panels in sequence. The two partitions are parallel to the two side panels. The two partitions evenly divide the pallet body between the two side panels into three storage areas for storing material boxes. A limiting block is fixed on the pallet body in each storage area. The partitions are also provided with hook grooves for the pallet-hooking robotic arm to hook.

[0012] Furthermore, several guide wheels are provided on the outer walls of both the left and right ends of the base.

[0013] Furthermore: the base consists of a support frame and a first auxiliary support bar, a second auxiliary support bar, and a third auxiliary support bar fixed within the support frame. The support frame is formed by four hollow tubes connected end to end. The first, second, and third auxiliary support bars are all hollow tubes. Three parallel first auxiliary support bars are arranged within the support frame, with both ends of each first auxiliary support bar connected to the support frame. The second and third auxiliary support bars are perpendicular to the first auxiliary support bars. The second auxiliary support bar is positioned between the first auxiliary support bars and the support frame, and the third auxiliary support bar is fixed between two adjacent first auxiliary support bars.

[0014] With the above structure, the present invention can transport pallets or boxes on pallets at any position on the shelf to the sorting table through the docking system, and then transport the pallets or boxes on pallets to the designated position through the sorting table, thereby completing the automatic picking of parts. This not only greatly improves picking efficiency, but also effectively avoids picking errors. Furthermore, the present invention sets up multiple box storage areas on the pallet, so that multiple related boxes can be placed on one pallet, thereby completing the picking of multiple parts at once by hooking the pallet, which increases the practicality.

[0025] like Figure 1 The illustrated intelligent picking system for automotive parts includes a sorting table 1, a docking system 2, a shelf 3, and a pallet 4. Two shelves are arranged side-by-side, each with several pallets placed on it from top to bottom. Several material boxes are also placed on each pallet. Two docking systems are also arranged side-by-side, each located directly in front of one of the two shelves. The sorting table is positioned directly in front of the two docking systems. Each docking system has a discharge port on its front facing the sorting table and a retrieval port on its back facing the shelf. The docking system contains a material box gripping robotic arm and a pallet hooking robotic arm. The docking system uses these robotic arms to transport material boxes from the pallets and pallets from the shelf to the sorting table. The sorting table is L-shaped, and an empty material box conveying device 5 is located directly below its front end. This invention uses a docking system to transport pallets or boxes on pallets from any location on a shelf to a sorting table, and then uses the sorting table to transport the pallets or boxes to a designated location, thereby completing the automatic picking of parts. This not only greatly improves picking efficiency but also effectively avoids picking errors.

[0026] The aforementioned docking system has two internal support frames. Inside each support frame, from front to right, are several rollers. The two support frames are connected to a material box gripping robot arm and a pallet hooking robot arm via telescopic mechanisms. The support frames are also connected to a translation mechanism and a height adjustment mechanism. This invention, through the translation and height adjustment mechanisms, utilizes the material box gripping robot arm and the pallet hooking robot arm to grasp material boxes on pallets and pallets on shelves at any position on the shelf.

[0027] like Figure 2 , Figure 3 and Figure 4 The sorting station shown includes two side-by-side supports 1-1, two lifting supports 1-10, a conveyor belt mechanism 1-6, and left and right horizontal conveying mechanisms. The two lifting supports are connected to the two supports through the lifting mechanism. The upper end of the supports is U-shaped. An auxiliary worktable 1-3 is provided on the convex surface of the two supports near one end, and a worktable 1-2 is also provided on the convex surface of the two supports away from each other. A protective cover 1-4 is fixed on the front end of the two supports. Four partitions 1-5 are arranged from left to right between the auxiliary worktable and the worktable on the same support. The four partitions are fixed on the lifting supports in the same support. The left and right horizontal conveying mechanisms are installed on the four partitions on the same support. Three independent conveyor belt mechanisms are arranged from left to right on the same support. A conveyor belt mechanism is arranged between each two adjacent partitions. The left and right horizontal conveying mechanisms are driven by the lifting mechanism so that their upper ends are flush with the upper surfaces of the auxiliary worktable and the worktable. During operation, the docking system adjacent to the sorting table will remove the material boxes or pallets containing parts from the shelf and place them on the support as needed. When a material box is removed, it will be automatically transported outward by the conveyor belt. When a pallet is removed, the lifting mechanism will lift the left and right horizontal conveyor mechanisms upward so that the pallet is no longer in contact with the conveyor belt. The left and right horizontal conveyor mechanisms will then move the pallet horizontally according to the actual situation, making it easy for the operator to pick it up. The pallet can move parallel to the two supports.

[0028] like Figure 3 The conveyor belt conveying mechanism shown consists of a conveyor belt 1-6-1, side covers (1-6-2), a drive roller, a driven roller, and a conveyor motor. Two side covers are arranged opposite each other between two adjacent partition frames on the same support. The two side covers are fixed on the same support. The drive roller and the driven roller are respectively installed between the front and rear ends of the two side covers. The drive roller is connected to a conveyor motor fixed inside one of the side covers. The conveyor belt wraps around the outside of the drive roller and the driven roller and conveys the material through the rotation of the drive roller and the driven roller.

[0029] like Figure 4The lifting mechanism shown includes a servo motor, a reducer, a bevel gear transmission assembly, and a worm gear jack. Two lifting supports are connected to the support via worm gear jacks. The servo motor is fixed to one support via a motor mounting bracket. The reducer is connected to the servo motor, and its output shaft extends from both sides. The output shafts on both sides are respectively connected to a worm gear jack within one of the supports via the bevel gear transmission assembly. During operation, the servo motor is started, simultaneously driving the worm gear jacks on both sides, causing the two lifting supports to rise and fall synchronously under the action of the worm gear jacks.

[0030] like Figure 2 , Figure 3 , Figure 5 and Figure 6 The left and right horizontal conveying mechanism includes conveying rollers 1-9, driven sprockets 1-11, driving sprockets, and chains. Four partitions on the same support frame are provided with mounting slots matching the conveying rollers. The conveying rollers are embedded and rotatably connected to the mounting slots on the partitions, with the upper end of the conveying rollers extending out of the mounting slots. One of the four conveying rollers on the same lifting frame is an electric roller, which rotates within the mounting slot and has its output shaft extending out of the mounting slot. A driving sprocket is mounted on the output shaft of the electric roller extending out of the mounting slot. The other three conveying rollers are rotatably connected to the mounting slots via rotating shafts. One end of the rotating shaft also extends out of the mounting slot and is equipped with driven sprockets 1-11. The driving sprockets are connected to the other three driven sprockets via chains.

[0031] Each of the two supports has an auxiliary support 1-7 located on the outer side of one end away from the other. The auxiliary support is close to the support and has a touch screen 1-12 on its top. The touch screen is electrically connected to a controller installed in the auxiliary support. The auxiliary support also has a maintenance port 1-13 and a storage box 1-14 on its side wall.

[0032] like Figure 7 The pallet comprises a pallet body 4-1, a base 4-2, side plates 4-3, partitions 4-4, and limiting blocks 4-5. The pallet body is mounted on the base. Two side plates and two partitions are provided, with the two side plates fixed to the top of the left and right ends of the pallet body respectively. Two partitions are sequentially fixed to the pallet body between the two side plates, arranged parallel to the two side plates. The two partitions evenly divide the pallet body between the two side plates into three storage areas for storing material boxes. A limiting block is fixed to the pallet body in each storage area. The partitions also have hook grooves 4-4-1 for a pallet-hooking robotic arm. This invention, through the use of partitions, divides the pallet body into different storage areas, thereby increasing its practicality by storing related parts boxes.

[0033] like Figure 8 Several guide wheels 4-6 are provided on the outer walls of both the left and right ends of the base shown; the present invention facilitates the removal or placement of trays from the shelf by adopting the above design.

[0034] like Figure 9 The base shown consists of a support frame 4-2-1 and three auxiliary support bars 4-2-2, 4-2-3, and 4-2-4 fixed within the support frame. The support frame is formed by four hollow tubes connected end-to-end. The first, second, and third auxiliary support bars are all hollow tubes. Three parallel first auxiliary support bars are arranged within the support frame, with their ends integrally connected to the support frame. The second and third auxiliary support bars are perpendicular to the first auxiliary support bars. The second auxiliary support bar is positioned between the first auxiliary support bars and the support frame, and the third auxiliary support bar is fixed between two adjacent first auxiliary support bars. This invention achieves a lightweight design by employing the above structure, significantly reducing the overall weight of the tray.

[0035] In summary, this invention, through its docking system, can transport pallets or boxes on pallets from any location on the shelf to the sorting table, and then transport the pallets or boxes to designated locations via the sorting table, thereby completing the automatic picking of parts. This not only greatly improves picking efficiency but also effectively avoids picking errors. Furthermore, this invention sets up multiple box storage areas on the pallet, allowing multiple related boxes to be placed on a single pallet. This enables the picking of multiple parts at once by hooking the pallet, thus increasing practicality.
