Description

Technical Field

[0001] This invention relates to the field of automotive parts assembly technology, and in particular to a modular assembly and conveying system for automotive sub-instrument panels. Background Technology

[0002] The automotive sub-instrument panel assembly, also known as the center console or central tunnel, is a key component in vehicle interiors that combines functionality and aesthetics. It typically integrates multiple functional elements such as the gear shift mechanism, cup holders, storage compartments, air conditioning controllers, multimedia panels, and wiring harnesses. With the increasing demand for personalized configurations and intelligent experiences in the automotive market, the structure of the sub-instrument panel assembly has become increasingly complex, with a significant increase in variations. This places higher demands on the flexibility, automation, and precision of the assembly process. In traditional automotive interior assembly lines, the sub-instrument panel assembly is often assembled using fixed workstations or rigid conveyor lines. This involves transferring the sub-instrument panel frame sequentially to various assembly stations via fixed pallets or simple conveyor devices, with components installed manually or using auxiliary equipment. This method is ill-suited to the diverse, small-batch, and fast-paced production model of modern automobiles, exhibiting inherent drawbacks such as low efficiency, poor flexibility, and susceptibility to errors.

[0003] In recent years, the concept of modular assembly and flexible conveying has been gradually promoted in the automotive manufacturing field. Its core lies in concentrating most of the assembly processes of complex assemblies on a mobile and intelligent carrier. This carrier can automatically flow in a preset path and has functions such as positioning, lifting, and flipping to support human-machine collaborative operations in the optimal posture.

[0004] However, existing related technologies still have significant shortcomings. For example, Chinese invention patent CN120902860A discloses a conveying and transfer device for assembling a sub-instrument panel assembly, which uses a top drive assembly in conjunction with a bottom wheel system to achieve motion conveying. However, this structure has two major problems in practical applications: First, due to the large size of the sub-instrument panel assembly itself, it is prone to derailment or structural interference when passing through curves, leading to unstable conveying. Furthermore, its pick-and-place mechanism lacks width adjustment capability, making it difficult to adapt to different product specifications and limiting its applicability. Second, its top track has an open design, which easily accumulates dust and particulate impurities during long-term operation, thus interfering with the normal operation of the drive assembly and, in severe cases, even causing conveying interruption. These defects restrict the reliability, versatility, and automation level of the assembly system.

[0005] Therefore, there is an urgent need to develop a new type of modular assembly and conveying system for automotive sub-instrument panels to address the shortcomings of existing technologies in terms of flexibility, stable conveying, and environmental adaptability, thereby improving assembly efficiency and product quality consistency. Summary of the Invention

[0006] The purpose of this invention is to provide a modular assembly and conveying system for automotive sub-instrument panels to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A modular assembly and conveying system for an automotive sub-instrument panel assembly includes a frame structure, a conveying structure, and an adjusting structure. The frame structure is generally arranged in a ring. The conveying structure includes a movable seat, a guide arm, and a lower guide member. The movable seat and the lower guide member move synchronously along the top and bottom tracks of the frame structure, respectively. The guide arm is movably connected between the movable seat and the lower guide member, and a set of lifting seats with relative movement is provided on the guide arm. A clamping plate is installed on the lifting seats. The adjusting structure includes a connecting guide seat, a sliding bar, a swing arm, an adjusting frame, and an electric suction cup. The connecting guide seat is fixedly installed on one side of the lifting seat. The sliding bar is slidably engaged between the inner walls of the connecting guide seat. The top of the sliding bar is rotatably provided with the swing arm. The other end of the swing arm is movably connected to the adjusting frame through a guide bolt. The electric suction cup is installed on the side wall of the adjusting frame. Holding components are also provided on the top surface of both ends of the adjusting frame to keep the adjusting frame in the middle position.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. By adopting a three-point positioning and guiding mechanism consisting of the meshing point of the upper guide component, the lower guide component, and gear one, combined with the flexible adjustability of the rotating connecting component, the derailment problem caused by the shift of the center of gravity or changes in product width in the traditional wheel structure on curves is effectively solved, and the conveying stability is significantly improved.

[0009] 2. The dual-point constraint clamping system consisting of a clamping plate and an electric suction cup, combined with the radial telescopic mechanism driven by the swing arm, can effectively achieve adaptive loading and unloading of sub-instrument panels of different widths and shapes. Its flexible adaptability covers mainstream vehicle platforms. In addition, the lifting seat adopts a composite lifting mechanism of bidirectional screw and dovetail guide, which effectively suppresses jamming caused by off-center load while ensuring lifting synchronization and improving clamping reliability.

[0010] 3. The photoelectric alignment unit composed of light-emitting diodes and photosensitive sensors achieves high-precision alignment between the conveyor structure and the workstation, and triggers the dust cleaning action to form a closed-loop control logic of "run-positioning-cleaning", which improves the system's automation level. Furthermore, the embedded three-stage dust cleaning architecture of scraping shell-groove-dust collection integrates the dust cleaning action inside the frame, avoiding the problem of dust accumulation on open guide rails, ensuring long-term operating accuracy, and extending the equipment maintenance cycle.

[0011] In summary, the modular assembly and conveying system for automotive sub-instrument panels provided by this invention, through structural innovation and functional integration, significantly improves the system's operational stability, product adaptability, environmental adaptability, and automation control level without sacrificing conveying efficiency. It is suitable for modern automotive interior assembly production lines with multiple product varieties, high cycle times, and long operating cycles. Attached Figure Description

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0016] Please see Figure 1-9 The present invention provides a technical solution: a modular assembly and conveying system for automotive sub-instrument panels, comprising a frame structure 1, at least two sets of conveying structures 2 that circulate along a circular track, an adjustment structure 3 disposed on each conveying structure 2, and a cleaning structure 4 embedded inside the frame structure 1. The system achieves stable conveying, precise positioning, and reliable picking and placing of sub-instrument panels of various specifications in a high-speed production line through technologies such as double-layer guide rail collaborative guidance, gear meshing drive, clamping-adsorption composite picking and placing, and embedded dynamic dust removal.

[0017] The frame structure 1 includes a centrally located support frame 11 and multiple symmetrically distributed support frames 12 (an even number) on both sides. Both support frames 11 and support frames 12 adopt an "I"-shaped cross-section steel structure. The upper guide rail 13 is fixedly connected between the top end walls of each support frame 11 and support frame 12, and the lower guide rail 14 is fixedly connected between the bottom end walls of each support frame 11 and support frame 12. The two form a concentric double-layer ring track system. Both the upper guide rail 13 and the lower guide rail 14 are set in a ring track structure. Furthermore, a guide rail ring matching its ring track is fixed on the lower guide rail 14, and a guide rail groove matching its ring track is opened on the upper guide rail 13.

[0018] The conveying structure 2 includes a movable seat 21, a rotating connector 22, a guide rail arm 23, and a lifting seat 24, wherein the rotating connector 22 includes a connecting seat and a connecting shaft; The movable seat 21 is slidably disposed along the side wall of the upper guide rail 13, and the movable seat 21 is threadedly connected to the upper guide member 211. The upper guide member 211 is a cylindrical structure, and its bottom end slides along the bottom wall of the guide rail groove. Its outer diameter is greater than the maximum width of the groove 131, ensuring that it will not fall into the groove 131 when passing through it. Furthermore, an external thread is provided on the outer surface of the upper guide member 211 that contacts the movable seat 21. The bottom end of the upper guide member 211 is slidably disposed along the bottom wall of the guide rail groove. A gear 212 (driven by a motor built into the movable seat 21) is rotatably disposed between its inner walls in the vertical direction of the movable seat 21. The gear 212 moves along the side wall of the upper guide rail 13. The upper guide rail 13 is provided with a toothed groove (not shown in the figure) along its side wall trajectory for the gear 212 to move. A circular connecting seat is fixedly installed on the bottom wall of the movable seat 21. A "T"-shaped connector is connected to the top wall of the guide rail arm 23. The "T"-shaped end of the connecting shaft is rotatably disposed between the inner walls of the connecting seat, so that the guide rail arm 23 and the movable seat 21 are in a rotatable connection state. A lower guide member 25 is rotatably disposed on the bottom end of the guide rail arm 23 through a shaft connection. The lower guide member 25 is a semi-ring structure and is slidably disposed along the surface of the guide rail ring.

[0019] Vertical groove 1 is provided on both sides of the vertical sidewall of the guide rail arm 23. Two dovetail-shaped guide blocks are fixed on the lifting seat 24 and slide along the inner wall of the vertical groove 1. A drive block is also fixed on the lifting seat 24. Two vertical groove 2 are provided on the other side of the vertical sidewall of the guide rail arm 23. A bidirectional screw 231 is rotatably provided between the two vertical groove 2 (the threads on the bidirectional screw 231 in different vertical groove 2 are opposite, and the bidirectional screw 231 is driven to rotate by a motor built into the guide rail arm 23). The drive block slides between the inner walls of the vertical groove 2, and the bidirectional screw 231 passes through the drive block and is threadedly driven to it. A horizontally arranged clamping plate 241 is also fixed on the sidewall of the lifting seat 24 for radial limiting of the sub-instrument panel assembly frame. Two clamping plates 241 on the same guide rail arm 23 are arranged opposite to each other.

[0020] It needs to be further explained that, such as Figure 1 As shown, the conveying structure 2 moves in a cyclical manner from position ABCD. The motor drives the gear 212 to move around the tooth groove, thereby synchronously driving the moving seat 21 to move. When one of the moving seats 21 passes through the circular track, the flexible adjustment of the top and bottom of the guide arm 23 (i.e., the shaft rotation state) makes it match the circular movement of the moving seat 21 and maintain a straight state. The other moving seat 21 continues to move in a straight line and moves through the circular track in the same way. This reciprocating motion occurs between the upper guide rail 13 and the lower guide rail 14.

[0021] The adjustment structure 3 includes a connecting guide seat 31, a sliding bar 32, an adjustment frame 34, an electric suction cup 35, a swing arm 36, an adjustment bar one 38, and an adjustment bar two 39; Connecting guide seats 31 are fixedly connected to two lifting seats 24 at the same horizontal height via two connecting plates 242 (one is a vertical plate structure, and the other is an "L" shaped plate structure). Two parallel connecting plates 311 are also fixedly connected to the side wall of the connecting guide seat 31 facing the guide arm 23. The connecting plates 311 slide in contact with the guide arm 23, and the upper connecting plate 311 is fixedly connected to the bottom end of the vertical connecting plate 242. A sliding strip 32, moving along its length, is slidably arranged between the inner walls of the connecting guide seat 31. A dovetail-shaped guide bar 1 is connected to the side wall of the sliding strip 32 facing the connecting guide seat 31. The guide bar 1 slides and adjusts along the inner wall of the connecting guide seat 31. A motor 1 is installed on the side wall of the other "L" shaped connecting plate 242, and a motor 1 is mounted on the end of its output shaft. There is a gear 33, which passes through the connecting plate 311 of the screening and meshes with the top surface of the sliding bar 32 for transmission (i.e., several tooth grooves are opened on the top surface of the sliding bar 32). A swing arm 36 is provided on the top surface of one end of the sliding bar 32 by a motor 2 (installed on the bottom wall of the sliding bar 32). A "T"-shaped guide bolt 361 is installed on the other end of the swing arm 36. An adjustment frame 34 is provided between the two swing arms 36. The guide bolts 361 on both sides move symmetrically between the inner walls of the adjustment frame 34. Two sets of electric suction cups 35 are also installed on one side wall of the adjustment frame 34. A photosensitive sensor 37 is also embedded in the middle of one side wall of the upper adjustment frame 34. The photosensitive sensor 37 and the light-emitting diode 121 installed at the central axis position of the side wall of the support frame 2 12 constitute a photoelectric alignment unit. When the conveyor structure 2 moves to the preset work station B (or D), the photosensitive sensor 37 receives the light signal emitted by the light-emitting diode 121, triggering the PLC controller to execute the work station handover command or start the cleaning structure 4. At this time, the conveyor structure 2 is exactly symmetrical about the central axis of the support frame 12.

[0022] In addition, retaining components are respectively provided on both sides of the top surface of the adjusting frame 34. The retaining components include adjusting bar 1 38 and adjusting bar 2 39. A connecting seat 1 is fixed on the side wall of the "L"-shaped connecting plate 2 311. Adjusting bar 2 39 slides on the side wall of the connecting plate 2 311. The two slide together through a dovetail-shaped guide bar 2. The guide bar 2 is fixed on the side wall of adjusting bar 2 39 and is the same length as it. A connecting seat 2 is fixed on the top surface of adjusting bar 2 39. A tension spring 391 is connected between the connecting seat 1 and the connecting seat 2. The tension spring 391 is installed along the length direction of adjusting bar 2 39. One end of adjusting bar 1 38 is connected to the top surface of the adjusting frame 34 through a shaft. A guide bar 3 (dovetail type) is fixed on the top surface of adjusting bar 1 38 and is arranged along its length direction. The guide bar 3 passes through and slides between the bottom inner walls of adjusting bar 2 39. Limiting blocks are fixed at both ends of the guide bar 3. The limiting blocks are installed on the top surface of adjusting bar 1 38.

[0023] It should be further explained that after the clamping plate 241 of the conveying structure 2 clamps and fixes the sub-instrument assembly to be assembled, the second motor below the swing arm 36 is started, which drives the swing arm 36 to rotate and adjust via the shaft. Thus, under the synchronous movement of the two swing arms 36, the adjusting frame 34 moves closer to the side where the sub-instrument assembly is located, until the electric suction cup 35 contacts and fixes the sub-instrument assembly. The system automatically records the stopping state of the second motor at this time (denoted as state E). At this time, the sub-instrument assembly is limited to between the clamping plate 241 and the electric suction cup 35. The conveying structure 2 then moves to... Figure 1 At position A, motor 2 continues to start and, via swing arm 36, drives adjusting frame 34 to push the adsorbed sub-instrument assembly forward to the next process step. Simultaneously, as motor 2 continues to start, the upper and lower clamping plates 241 move to the sides and stop, making the sub-instrument assembly easier to move. After the robot arm at the process position picks up the pushed sub-instrument assembly, the conveying structure 2 starts again and moves forward to transport it. When it reaches position B, the robot arm at the corresponding process step delivers the assembled sub-instrument assembly (the other sub-instrument assembly picked up at position A is still being assembled) to the electric suction cup 35. The sub-instrument assembly is firmly adsorbed by the electric suction cup 35. Then, the motor 2 rotates in the opposite direction and drives the adjustment bracket 34 to move back. When it moves back to the return state E of the motor 2, it pauses. At this time, the upper and lower clamping plates 241 move towards the sub-instrument assembly again and clamp it firmly. Then, the conveying structure 2 continues to drive it forward. When it moves to position C, the process is the same as when it reaches position A. The sub-instrument assembly on the conveying structure 2 is pushed to the corresponding process for assembly. Then, the empty conveying structure 2 moves forward to position D and picks up the sub-instrument assembly that has been assembled at position C again and clamps it forward for conveying.

[0024] The above process is limited to the state description of the four positions ABCD shown in the figure. If there are multiple workstations for assembly, the same process shall be followed. However, it should be noted that two adjacent workstations cannot be in the same state. The material must first be fed to the assembly workstation and then picked up from the assembly workstation and returned to the conveyor structure 2, and so on in a cyclical operation.

[0025] The cleaning structure 4 includes a telescopic cylinder 41, a mounting shell 42, a scraper shell 43, a collection box 44, a baffle 45, and a lifting motor 46; An inner groove 111 and an outer groove 112 are connected at both ends of the support frame 11. A mounting shell 42 is vertically adjustable within the inner groove 111. A telescopic cylinder 41 is fixedly installed through the mounting shell 42. Two sets of lifting motors 46 are also fixedly installed on the top surface of the support frame 11 above the inner groove 111. The output shaft of the lifting motor 46 is connected and fixed to the upper surface of the mounting shell 42. A scraper shell 43 is movably disposed within the outer groove 112. The longitudinal section of the scraper shell 43 is a right-angled trapezoid. Both the inclined surface and the bottom surface of the scraper shell 43 are open, forming an open cavity inside for receiving... To collect dust and impurities, the output shaft end of the telescopic cylinder 41 is connected and fixed to one side end wall of the scraper shell 43. A contact sensor 113 is also embedded in the inner wall of the outer groove 112. When the end wall of the scraper shell 43 contacts the contact sensor 113, the output shaft of the telescopic cylinder 41 is retracted to its shortest length. A baffle 45 is rotatably arranged on the inclined surface of the outer groove 112 (the baffle 45 is adjusted by shaft drive by a micro motor). A collection box 44 is also slidably arranged below the baffle 45 along the inner wall of the support frame 11. When the baffle 45 is rotated downward to the maximum angle, the baffle 45 is vertically downward.

[0026] When the conveyor structure 2 completes one cycle and returns to the starting area, the PLC controller executes the following actions sequentially based on the feedback signal from the photoelectric alignment unit: S1. Control the extension cylinder 41 to extend, so that the scraper 43 moves horizontally to the groove 131 of the upper guide rail 13. S2. Control the start of the lifting motor 46 to make the scraper 43 descend vertically to the bottom of the groove 131, with its three side walls fitting against the inner wall of the groove 131. S3, control the telescopic cylinder 41 to retract, and scraper 43 to bring the dust accumulated in the groove 131 back to the baffle 45. S4. After the scraper 43 moves back to trigger the contact sensor 113, the baffle 45 opens downwards, and the dust slides down the slope into the collection box 44. S5. When the collection box 44 is full, an alarm signal is issued (built-in weight sensor, not shown in the figure), prompting manual replacement and cleaning.

[0027] The entire dust removal process is automatically executed during the non-operational periods of the conveying structure 2, without the need for machine shutdown or intervention, and all actions are completed within the enclosed cavity to prevent dust from overflowing.

[0028] A through hole communicating with the outer groove 112 is provided on the upper guide rail 13 at the position opposite to the end of the support frame 11. A cover plate 132 is rotatably provided on one end of the through hole via a motor drive shaft. When the cover plate 132 is opened, the scraper 43 can move into the upper guide rail 13. Furthermore, a groove 131 matching the bottom trajectory of the scraper 43 is provided on the bottom wall of the upper guide rail 13. After the scraper 43 moves to the lowest height, it can slide in contact with the groove 131.

[0029] It should be further explained that, since the guide rail groove of the upper guide rail 13 is open, the accumulation of dust and impurities is unavoidable, thus affecting the movement of the conveying structure 2. To address this issue, a cleaning structure 4 is provided. The upper guide member 211 of the conveying structure 2 moves continuously in the guide rail groove. As the upper guide member 211 moves, the impurities and dust accumulated in the guide rail groove are carried forward. Whenever it passes the corresponding grooves 131 on both sides of the support frame 11, the impurities and dust fall into the grooves 131. Since the diameter of the upper guide member 211 is greater than the maximum width of the groove 131, the upper guide member 211 can pass smoothly through the grooves 131 without sinking. When the conveying structure 2 moves to position B, the photodiode on the conveying structure 2 is triggered. Subsequently, the cover plate 132 rotates upward and opens under the drive of the motor, revealing the through hole. Then, the telescopic cylinder 41 moves forward. The scraper shell 43 is pushed to its furthest distance and stops. At this point, the scraper shell 43 is directly above the groove 131. Immediately afterwards, the lifting motor 46 starts and drives the mounting shell 42 and the telescopic cylinder 41 to descend to the lowest position, so that the scraper shell 43 descends and falls exactly into the groove 131, contacting the inner walls of the groove 131 on all three sides. Then, the output shaft of the telescopic cylinder 41 begins to reset and retract, causing the scraper shell 43 to carry the dust and impurities in the groove 131 to move into the outer groove 112. It moves back until the scraper shell 43 touches the contact sensor 113 and stops. At this time, the cover plate 132 rotates downward to close the through hole. At the same time, the baffle 45 opens downward, and the dust and impurities fall into the collection box 44. Then the baffle 45 resets upward. At the same time, the lifting motor 46 also drives the telescopic cylinder 41, the mounting shell 42 and the scraper shell 43 to move upward to the highest position (that is, the output shaft of the lifting motor 46 retracts to its shortest length) and stops. By setting cleaning structures 4 on both sides of the support frame 11, the treatment effect of impurities and dust in the guide rail groove can be effectively improved, and the movement efficiency of the conveying structure 2 can be improved.
