Description

Technical Field

[0001] This utility model relates to the field of vehicle automated assembly technology, specifically to a precision splicing type automated production line system for automotive central control assemblies. Background Technology

[0002] With the development of automotive intelligence, the automotive central control assembly integrates multiple modules such as navigation, entertainment, and vehicle networking. Its assembly precision and production efficiency are crucial to the overall vehicle production capacity. Currently, the assembly of automotive central control assemblies largely relies on intermittent assembly lines with a rotary layout. To meet the requirements of multi-process precision assembly, this assembly line uses a two-layer linear conveyor system arranged in parallel as the core conveyor. Pallets for carrying semi-finished or finished central control assemblies are evenly spaced on both layers of the conveyor system. All pallets circulate between the upper and lower layers via the conveyor mechanism of the conveyor system. The upper conveyor system is typically used to transfer automotive central control assemblies to be assembled to each assembly station. After all assembly processes are completed, the finished product flows with the pallet to the end of the assembly line for removal from the line. The pallet then flows back to the initial end through the lower conveyor system, forming a closed-loop production process.

[0003] However, existing assembly lines still generally use manual methods to remove finished automotive central control assemblies from the production line. This method has technical defects such as low production efficiency, high labor intensity, insufficient operational safety, and difficulty in systematic management.

[0004] Therefore, for the current intermittent operation assembly line layout for rotating automotive center console assembly line, there is an urgent need for an assembly line system that can be precisely connected to the end of this type of assembly line, achieve automated assembly line removal, and be integrated into a systematic management system. Utility Model Content

[0005] In view of this, the present invention provides a precision docking type automated unloading system for automotive central control assemblies, which can precisely dock with the end of the assembly line and achieve automated unloading.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A precision docking-type automated production line system for automotive central control assemblies, the key features of which are: a rectangular production line compartment, the lower part of which is provided with a material inlet and at least one docking vehicle inlet and outlet, and a material plate sinking mechanism arranged inside the material inlet, the material plate sinking mechanism including a support frame, a rotary drag chain assembly disposed in the support frame, and a lifting transmission assembly for driving the support frame to move up and down in the production line compartment;

[0008] The unloading bin is equipped with a mechanical gripper, a lifting module that controls the up-and-down movement of the mechanical gripper, and a front-and-back linear module that controls the back-and-forth movement of the mechanical gripper. The top of the unloading bin is open, and a guide rail and a rack are installed on the top of both the front and back sides of the unloading bin. The front and back ends of the front and back linear modules slide onto the guide rails. The front and back linear modules are equipped with a drive shaft and a first motor that drives the drive shaft to rotate. Gears are installed at both ends of the drive shaft, and the gears mesh with the rack.

[0009] Using the above structure, the lifting transmission assembly drives the support frame to rise to the same height as the incoming material. The automotive central control assembly enters from the material inlet along with the material plate. Upon entry, the material plate first contacts a portion of the support frame. Then, the rotary cable chain assembly rotates to completely lift the material plate onto the support frame. The lifting transmission assembly drives the support frame to descend to the bottom. By adjusting the height and horizontal position of the mechanical gripper, the mechanical gripper is moved above the material plate. The lifting module then drives the mechanical gripper to move up and down, enabling the mechanical gripper to accurately grab the automotive central control assembly on the material plate. At this time, the automatically controlled shuttle car enters the off-line warehouse from the shuttle car inlet and outlet. The mechanical gripper places the automotive central control assembly onto the shuttle car, and the shuttle car then exits from the shuttle car inlet and outlet, completing one automated off-line shuttle of the central control assembly.

[0010] Preferably, a rectangular support beam is fixed to the top of the unloading compartment, and a metal support plate is provided on top of the support beam. The inner end of the metal support plate protrudes inward from the support beam. The rack is disposed on the lower side of the metal support plate, and the guide rail is disposed on the metal support plate. This structure, with the inner end of the metal support plate protruding inward from the support beam, expands the arrangement space for the guide rail and rack, accommodating the larger travel requirements of the front and rear linear modules. Furthermore, the layered layout, with the rack disposed on the lower side of the metal support plate and the guide rail disposed on top, avoids interference between the guide rail and rack during installation and movement, further optimizing the utilization of the top space and making the overall structure more compact.

[0011] Preferably, a CCD depth sensor camera is mounted on the lower side of the front and rear linear modules. With this structure, the CCD depth sensor camera can accurately identify the specific position, orientation, and dimensional characteristics of the central control assembly on the material plate, providing precise positioning data for the mechanical gripper's grasping action.

[0012] Preferably, the rotary cable chain assembly includes two sets of annular cable chains disposed on both sides of the inner end of the support frame, and a first drive structure for driving the two sets of annular cable chains to rotate cyclically. Both sets of annular cable chains extend along the material feeding direction. This structure provides stable support from both sides of the material plate, resulting in more uniform force distribution on the material plate during transport and significantly improving the stability and accuracy of the material plate transport.

[0013] Preferably, the material plate sinking mechanism includes a mounting frame, with the support frame located inside the mounting frame and capable of vertical movement relative to it. The lifting transmission assembly includes four sets of annular chains positioned at the front and rear ends of the mounting frame. These four sets of annular chains extend along the height direction of the mounting frame and are symmetrically arranged in pairs. The mounting frame is equipped with a second driving structure that drives the four sets of annular chains to rotate cyclically. The support frame is fixedly connected to the four sets of annular chains via four fixed mounting seats. This structure generates uniform driving and supporting forces on the support frame, effectively preventing tilting, swaying, or jamming due to uneven force during lifting, significantly improving the stability and verticality accuracy of the support frame's lifting.

[0014] Preferably, the inner end of the support frame is provided with a limiting structure, which includes a cylinder and a limiting seat connected to the piston rod of the cylinder. The extension and retraction of the cylinder can cause the limiting seat to move up and down. With the above structure, the upward movement of the limiting structure can position the material plate, ensuring that the material plate can stop accurately on the support frame.

[0015] Preferably, the support frame is constructed in an n-shape. This structure facilitates connection with the material plate.

[0016] Preferably, both ends of the support frame opening are provided with outwardly inclined slopes. With the above structure, the slopes play a guiding and buffering role during the connection between the material plate and the open end of the support frame.

[0017] Preferably, the number of the docking vehicle inlets and outlets is provided in two sets: one set of docking vehicle inlets and outlets is directly opposite the material inlet, and the other set of docking vehicle inlets and outlets is located beside the material inlet.

[0018] Preferably, the mechanical gripper includes two symmetrically arranged gripping arms, which can move away from and towards each other. This structure generates a balanced gripping force from both sides of the automotive central control assembly, ensuring the structural integrity and posture stability of the workpiece during gripping and transfer.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The precision docking type automated finished product unloading system provided by this utility model operates as follows: During operation, the lifting transmission component drives the support frame to rise to the same height as the incoming material. The automotive central control assembly enters from the material inlet along with the material plate. Upon entry, the material plate first contacts a portion of the support frame. Subsequently, the rotary drag chain component rotates to completely lift the material plate onto the support frame. The lifting transmission component then drives the support frame to descend to the bottom. By adjusting the height and horizontal position of the mechanical gripper, the mechanical gripper is moved above the material plate. The lifting module then drives the mechanical gripper to move up and down, enabling the mechanical gripper to precisely grab the automotive central control assembly from the material plate. At this time, the automatically controlled docking vehicle enters the unloading bin from the docking vehicle inlet and outlet. The mechanical gripper places the automotive central control assembly onto the docking vehicle, and the docking vehicle then exits from the docking vehicle inlet and outlet, completing one automated unloading docking of the central control assembly.

[0021] 2. The precision-connecting automated finished product unloading system provided by this utility model cleverly utilizes the top space on both sides of the unloading bin for the left and right movement control of the front and rear linear modules. By installing guide rails and racks, and using the meshing transmission of gears and racks and the sliding support of guide rails, the front and rear linear modules are directly driven to move left and right, eliminating the need for additional standard moving modules, greatly simplifying the equipment structure, reducing the overall weight of the equipment and achieving lightweight design, and also reducing the space occupied by the equipment, making the overall structure more compact and more suitable for the limited layout space of the workshop.

[0022] 3. The precision splicing automated finished product unloading system provided by this utility model requires no manual intervention throughout the entire process, achieving fully automated precision splicing and unloading. This effectively reduces errors caused by manual operation, significantly improves the unloading efficiency of the central control assembly, and ensures stable coordinated operation of each component, further guaranteeing the reliability and stability of the unloading process and enhancing the practical value and production applicability of the equipment.

[0031] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0032] like Figure 1 The diagram illustrates a precision-connected automated production line system for automotive central control assemblies. It includes a rectangular production line compartment A with an open top. The lower part of compartment A has a material inlet a and at least one connecting vehicle inlet b. In this embodiment, the material inlet a is located on the right side of compartment A. Two sets of connecting vehicle inlets b are provided: one set directly opposite the material inlet a, and the other set beside the material inlet a (i.e., one set on the left side of compartment A, and the other set at the rear). A material plate sinking mechanism 1 is arranged inside the material inlet a, combined with… Figure 2 and Figure 5 As shown, the material plate sinking mechanism 1 includes a support frame 1a, a rotary cable chain assembly 1b disposed within the support frame 1a, and a lifting transmission assembly 1c for driving the support frame 1a to move up and down within the lowering bin A. The lowering bin A is equipped with a mechanical gripper 2, a lifting module 4 for controlling the up-and-down movement of the mechanical gripper 2, and a forward-backward linear module 3 for controlling the forward-backward movement of the mechanical gripper 2. Figure 2 and 4 As can be seen, a guide rail 3a and a rack 3b are installed on the top of both the front and rear sides of the unloading compartment A. The front and rear ends of the linear modules 3 slide and overlap on the guide rail 3a. The linear modules 3 are equipped with a drive shaft 3d and a first motor 3e that drives the drive shaft 3d to rotate. Gears 3f are installed at both ends of the drive shaft 3d, and the gears 3f mesh with the rack 3b. The first motor 3e drives the drive shaft 3d to rotate. Under the meshing transmission action of the gears 3f and the rack 3b, the linear modules 3 can be driven to move back and forth along the length of the rack 3b, which realizes the left and right movement control of the mechanical gripper 2.

[0033] Based on the above structural design, when the system is working, the lifting transmission component 1c drives the support frame 1a to rise to the same height as the incoming material. The automotive central control assembly material enters from the material inlet a along with the material plate. Upon entry, the material plate first contacts a portion of the support frame 1a. Then, the rotary drag chain component 1b rotates to completely lift the material plate onto the support frame 1a. The lifting transmission component 1c drives the support frame 1a to descend to the bottom. By adjusting the height and horizontal position of the mechanical gripper 2, the mechanical gripper 2 is moved above the material plate. The lifting module 4 drives the mechanical gripper 2 to move up and down, so that the mechanical gripper 2 accurately grabs the automotive central control assembly on the material plate. At this time, the automatically controlled shuttle car enters the off-line warehouse A from the shuttle car inlet / outlet b. The mechanical gripper 2 places the automotive central control assembly onto the shuttle car, and the shuttle car then drives out from the shuttle car inlet / outlet b, completing one automated off-line shuttle of the central control assembly.

[0034] In the above structure, the left and right movement control of the front and rear linear modules 3 cleverly utilizes the top space on both sides of the lower line compartment A. By installing guide rails 3a and racks 3b, and using the meshing transmission of gears 3f and racks 3b and the sliding support of guide rails 3a, the front and rear linear modules 3 can be directly driven to move left and right. This eliminates the need for additional standard moving modules, greatly simplifies the equipment structure, reduces the overall weight of the equipment, achieves lightweight design, and reduces the space occupied by the equipment, making the overall structure more compact and better suited to the limited layout space of the workshop.

[0035] On the other hand, the meshing transmission of gear 3f and rack 3b has high transmission accuracy. Combined with the guiding effect of guide rail 3a, it can ensure that the front and rear linear modules 3 drive the mechanical gripper 2 to achieve precise left and right position adjustment. In addition, combined with the precise conveying of the material plate by the rotary drag chain component 1b in the material plate sinking mechanism 1, the precise adjustment of the material plate height by the lifting transmission component 1c, and the precise control of the vertical height of the mechanical gripper 2 by the lifting module 4, the mechanical gripper 2 can accurately grasp and place the central control assembly. At the same time, the docking vehicle can automatically enter and exit the unloading warehouse A through the docking vehicle inlet and outlet b. The whole process does not require manual intervention, realizing fully automated and precise docking and unloading. It effectively reduces the errors caused by manual operation, significantly improves the unloading efficiency of the central control assembly, and the stable coordinated action of each component further ensures the reliability and stability of the unloading process, and enhances the practical value and production applicability of the equipment.

[0036] like Figure 8As shown, an assembly line B has two linear conveyor systems B1 arranged along its length. The upper linear conveyor system B1 conveys materials from right to left, while the lower linear conveyor system B1 conveys materials from left to right. Multiple sets of material plates B3 are laid at equal intervals on the same linear conveyor system B1, with each material plate B3 corresponding to an assembly station. The left end of assembly line B has a lower line bin A, and the right end has a material lifting system C. The material lifting system C operates on the same principle as the material plate sinking mechanism 1 in the lower line bin A; its main function is to lift empty material plates B3 from the lower linear conveyor system B1 to the upper linear conveyor system B1. The assembled central control assembly is located on material plate B3. The upper linear conveyor system B1 conveys the material plate B3 to the left, sending it to the lower line bin A. Lower line bin A automatically unloads the incoming automotive central control assembly and lowers the empty material plate B3 until it is flush with the lower linear conveyor system B1, then sends it to the left end of the lower linear conveyor system B1. Meanwhile, the sheet metal lifting system C at the right end of assembly line B can transfer the empty material plate B3 from the left end of the lower linear conveyor system B1 to the right end of the upper linear conveyor system B1. By sequentially cycling through this process, all material plates B3 can circulate between the upper and lower linear conveyor systems B1, thus ensuring continuous and uninterrupted material feeding.

[0037] Please refer to Figure 2 and 4 A rectangular support beam A1 is fixed to the top of the lower section A. A metal support plate A2 is mounted on top of the support beam A1, with its inner end protruding inwards from the support beam A1. A rack 3b is positioned below the metal support plate A2, protruding from the support beam A1. A guide rail 3a is mounted on the metal support plate A2. The support beam A1 provides a stable mounting base for the metal support plate A2, while the metal support plate A2 provides a uniform and flat mounting surface for the guide rail 3a and rack 3b. The design of the inner end of the metal support plate A2 protruding inwards from the support beam A1 expands the arrangement space for the guide rail 3a and rack 3b, accommodating the larger travel requirements of the front and rear linear modules 3. Furthermore, the layered layout of the rack 3b below the metal support plate A2 and the guide rail 3a above it avoids interference between the guide rail 3a and rack 3b during installation and movement, further optimizing the utilization of the top space and making the overall structure more compact.

[0038] like Figure 3 As shown, two sets of CCD depth sensing cameras 5 are installed on the lower side of the front and rear linear modules 3. The CCD depth sensing cameras 5 can accurately identify the specific position, placement posture and size characteristics of the central control assembly on the material plate, providing accurate positioning basis for the gripping action of the mechanical gripper 2.

[0039] Please refer to Figure 5The rotary cable chain assembly 1b includes two sets of annular cable chains 1b1 disposed on both sides of the inner end of the support frame 1a, and a first drive structure for driving the two sets of annular cable chains 1b1 to rotate cyclically. Both sets of annular cable chains 1b1 extend along the material feeding direction. In this embodiment, each set of annular cable chains 1b1 is formed by multiple metal chain links hinged together by pins to form a closed annular structure. Through the coordinated operation of the two sets of annular cable chains 1b1, stable support can be formed from both sides of the material plate, making the force on the material plate more uniform during the conveying process, and significantly improving the stability and accuracy of the material plate conveying.

[0040] Specifically, the first drive structure includes two sets of first driving sprockets and first driven sprockets. A ring-shaped cable chain 1b1 is paired with one set of first driving sprockets and one set of first driven sprockets, with the ring-shaped cable chain 1b1 fitted onto the corresponding first driving sprockets and first driven sprockets. The first drive structure also includes a first drive shaft and a second motor that drives the first drive shaft to rotate. The two sets of driving sprockets are fixed at both ends of the first drive shaft, and the first driven sprockets are located at the end of the support frame 1a near the material inlet a. The second motor drives the first drive shaft to rotate, which in turn drives the two sets of first driving sprockets to rotate, thereby synchronously driving the ring-shaped cable chain 1b1 and the first driven sprockets to rotate synchronously.

[0041] refer to Figure 6 The material plate sinking mechanism 1 includes a rectangular mounting frame 11, which is open at the right and top ends. A support frame 1a is located inside the mounting frame 11 and can move up and down relative to it. The lifting transmission assembly 1c includes four sets of annular chains 1c1 arranged at the front and rear ends of the mounting frame 11, extending along the height direction of the mounting frame 11. Two sets of annular chains 1c1 are located at the front end and two sets at the rear end of the mounting frame 11, symmetrically arranged. The mounting frame 11 has a second driving structure that drives the four sets of annular chains 1c1 to rotate cyclically. The support frame 1a is fixedly connected to the four sets of annular chains 1c1 via four fixed seats 1d. The four sets of ring chains 1c1 are arranged symmetrically in pairs, and together with the four fixed seats 1d connected to the support frame 1a, they can form a uniform driving force and support force on the support frame 1a, effectively preventing the support frame 1a from tilting, shaking or jamming due to uneven force during the lifting process, and significantly improving the stability and verticality accuracy of the lifting of the support frame 1a.

[0042] In this embodiment, the specific structure of the second drive structure is as follows: The second drive structure includes four sets of second driving sprockets and second driven sprockets, each corresponding to one of four sets of annular chains 1c1. The second driving sprockets are located at the lower end, and the second driven sprockets are located at the upper end. The two sets of front-to-back second driving sprockets are synchronously driven by a second drive shaft 1f. Therefore, there are two sets of second drive shafts 1f. A synchronous chain 1g is sleeved between one end of each set of second drive shafts 1f. Thus, driving one set of second drive shafts 1f to rotate will drive both sets of second drive shafts 1f to rotate, thereby achieving synchronous rotation of the four sets of annular chains 1c1. The second drive structure also includes a third motor 1h, which drives one set of second drive shafts 1f to rotate.

[0043] like Figure 5 and 7 As shown, the inner end of the support frame 1a is provided with two sets of limiting structures 1e, located at the left and right ends of one side of the inner end of the support frame 1a. Each limiting structure 1e includes a cylinder 1e2 and a limiting seat 1e1 connected to the piston rod of the cylinder 1e2. The telescopic movement of the cylinder 1e2 causes the limiting seat 1e1 to move up and down. After the material plate enters the support frame 1a, the limiting structure 1e rises to position the material plate, ensuring that it stops precisely on the support frame 1a.

[0044] Please refer to Figure 5 In this embodiment, the support frame 1a is constructed as an n-shaped structure with an open right end to facilitate connection with the material plate.

[0045] Further, refer to Figure 5 Both ends of the opening of the support frame 1a are provided with outwardly inclined slopes 1a1. The slopes 1a1 play a guiding and buffering role during the connection between the material plate and the open end of the support frame 1a, effectively avoiding hard contact or jamming between the edge of the material plate and the open end of the support frame 1a, greatly reducing the risk of conveying interruption caused by docking deviation, and ensuring the smooth connection of the material plate.

[0046] refer to Figure 2 The mechanical gripper 2 includes two symmetrically arranged gripping arms 2a, which can move away from and towards each other. This design generates a balanced gripping force from both sides of the automotive center console assembly, ensuring the structural integrity and posture stability of the workpiece during gripping and transfer. Furthermore, it can flexibly adapt to automotive center console assemblies of different sizes and specifications, offering advantages in versatility and flexibility.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
