Description

Technical Field

[0001] This utility model relates to the field of sheet metal production equipment technology, and in particular to a sheet metal inspection, flipping and stacking production equipment using a robotic arm. Background Technology

[0002] Decorative panels are functional boards widely used in furniture manufacturing, architectural decoration, and other fields. Their surfaces are typically covered with decorative paper through a hot-pressing process, creating diverse textures and color effects. As a key substrate for decorative materials, the surface quality of decorative panels directly affects the aesthetics and grade classification of the final product. Therefore, during the production process, strict appearance defect inspection must be carried out on both sides of the panels, and fine grading (such as superior, good, and defective products) and stacking and packaging must be implemented according to the degree of defects.

[0003] In the traditional decorative panel production process, the hot-pressed panels need to undergo flipping, inspection, sorting, and stacking processes sequentially. Although existing production equipment includes basic conveying and inspection devices, core workstations still rely on manual operation: First, because the decorative surface of the hot-pressed panels is randomly facing up or down, manual flipping is required to meet the inspection requirements, which is inefficient and involves high labor intensity and damage to the panels. Second, in the sorting stage after inspection, operators need to visually judge the defect level and manually transfer the panels to the corresponding stacking area. Not only is the sorting speed difficult to match the production line rhythm, but manual sorting is also prone to misjudgment of the level and uneven stacking, affecting the subsequent automated subcontracting process. Third, existing sorting devices mostly adopt a binary classification structure of good and defective products, which cannot accommodate multi-level subdivision requirements, resulting in the need to add transfer racks for secondary sorting, further increasing the complexity and cost of the process.

[0004] The aforementioned problems, such as high reliance on manual labor, insufficient sorting accuracy, and limited equipment functionality, have become bottlenecks restricting the automation upgrade and quality control of decorative panel production. There is an urgent need to optimize the process through a collaborative system that integrates robotic arms, intelligent detection, and multi-level palletizing.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Detailed Implementation

[0052] This utility model provides a production equipment for inspecting, flipping, and stacking sheet metal using a robotic arm. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes the utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0053] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0054] Please refer to Figures 1 to 7 This embodiment discloses a production equipment for inspecting, flipping, and stacking sheet metal using a robotic arm, comprising:

[0055] The conveying and flipping mechanism 60 includes a first support 61, a multi-row first belt conveyor 62 located on the first support 61, and a flipping device 63. The decorative panel is conveyed and fed by the first belt conveyor 62, and the flipping device 63 is used to flip the decorative panel on the first belt conveyor 62.

[0056] The detection conveying mechanism 30 includes a second support 31 and a first conveying device 32 disposed on the second support 31, wherein the discharge end of the first conveying device 32 is set as the detection area;

[0057] Detection module 50 is used to detect appearance defects on the front or back of the decorative panel within the detection area;

[0058] The subcontracting and stacking mechanism includes a good product placement mechanism 10 for stacking good decorative panels and a defective product placement rack 80 for stacking defective decorative panels.

[0059] The robotic arm transfer mechanism 40 includes a robotic arm device 41, a suction cup frame 42 connected to the execution end of the robotic arm device 41, and several suction cups 43 fixed to the lower end of the suction cup frame 42. The decorative panels in the detection area are picked up by the robotic arm transfer mechanism 40 and transferred to the good product placement mechanism 10 or the defective product placement rack 80.

[0060] In the board inspection, flipping, and stacking production equipment of this embodiment, the conveying and flipping mechanism 60 smoothly conveys the hot-pressed decorative panels to the flipping station through a multi-row first belt conveyor device 62, and the flipping device 63 automatically completes the 180° flipping action of the decorative panels, replacing the traditional manual flipping operation. This not only significantly improves the flipping efficiency, but also avoids the problems of scratching the decorative paper or bumping the edges of the boards caused by manual operation. The flipped decorative panels are then transferred to the inspection conveying mechanism 30, and are accurately transferred to the inspection area by the first conveyor device 32. The inspection module 50 can use manual visual inspection or a CCD inspection device based on visual recognition technology to perform high-precision appearance defect scanning on the front and back of the decorative panels through manual visual inspection or CCD inspection device. When using a CCD inspection device, surface scratches, bubbles, color differences, and other defects can be detected simultaneously, and the grade (such as superior, good, or defective products) can be determined according to preset standards to ensure that the inspection results are objective and highly consistent.

[0061] After inspection, the robotic arm device 41 of the robotic transfer mechanism 40 responds quickly to the grade signal from the detection module 50. It uses several suction cups 43 at the end of the suction cup holder 42 to pick up the decorative panels and transfers them to the corresponding stacking areas using a high-precision positioning system: good decorative panels are precisely placed in the good product placement mechanism 10, while defective panels are transferred to the defective product placement rack 80. The suction cups 43 employ an adaptive negative pressure adsorption design, which can stably grasp and flatten decorative panels of different sizes, effectively solving problems such as tilting and misalignment during manual stacking. Furthermore, the good product placement mechanism 10 and the defective product placement rack 80, through a modular structural design, support multi-level classification stacking. For example, a transfer rack can be added later to achieve three-level subdivision of superior, good, and defective products, thereby reducing secondary sorting steps and minimizing process redundancy.

[0062] This equipment achieves a fully automated closed loop for the entire process of panel flipping, inspection, sorting, and palletizing through the coordinated operation of the conveying and flipping mechanism 60, the inspection module 50, and the robotic transfer mechanism 40. It not only solves the core pain points of high reliance on manual labor and low sorting efficiency in traditional production lines, but also optimizes the grade subdivision and sub-packaging process through a multi-level palletizing architecture, significantly improving production cycle and yield, while ensuring that the surface quality and palletizing flatness of the panels are not damaged during the transfer process.

[0063] Please refer to Figure 2The good product placement mechanism 10 includes a third support 11 and a second conveying device 12 located on the third support 11. The inlet end of the second conveying device 12 is set as the placement area, and the outlet end of the second conveying device 12 is set as the transfer area. A robotic transfer mechanism 40 transfers the decorative panels to the placement area, and the second conveying device 12 conveys the stacked panels in the placement area to the transfer area. The robotic transfer mechanism 40 accurately transfers the qualified decorative panels to the placement area of ​​the second conveying device 12, and achieves layer-by-layer stacking of the decorative panels through the stable adsorption and release action of the suction cup 43. After stacking, the second conveying device 12 automatically conveys the stacked good decorative panels from the placement area to the transfer area in an intermittent conveying mode, which facilitates the subsequent centralized transfer by forklifts or AGV equipment to the storage or packaging station, forming a seamless connection from sorting to outbound.

[0064] The second conveying device 12 can adopt a synchronous belt or roller conveyor design, which can carry the overall movement of multi-layer stacked decorative panels. During the conveying process, the stability of the stack is ensured by limiting mechanisms and buffer structures, avoiding the offset or tipping of the panels due to vibration or inertia. This mechanism, through the synergy of robotic arm transfer and automated conveying, not only improves the efficiency and flatness of good product stacking, but also achieves a dynamic balance between temporary storage and continuous transfer of stacked panels through the separation design of the panel placement area and the waiting transfer area. This significantly reduces manual handling and the resulting quality risks, while also reserving space for flexible expansion of the production line.

[0065] Furthermore, the second conveying device 12 includes multiple rows of first rollers 121, driven wheels 122 connected to the ends of the first rollers 121, a first motor mounted on a third bracket 11, a driving wheel connected to the output shaft of the first motor, and a synchronous belt for linking the driving wheel and the driven wheel 122. Both the inlet and outlet ends of the second conveying device 12 are equipped with at least two parallel first limiting bars 123. The multiple rows of first rollers 121 link the driving wheel and the driven wheel 122 via the synchronous belt, and are driven by the first motor to achieve synchronous rotation, ensuring that the good decorative panels stacked in the placement area are smoothly conveyed along the roller axis. The first limiting bars 123 at the inlet and outlet ends physically limit one side of the decorative panels, ensuring neat stacking.

[0066] The synchronous belt drive system, in conjunction with the evenly spaced layout of the first roller 121, can adapt to the conveying needs of decorative panels of different sizes, while also featuring low noise and high stability. The first limit bar 123 adopts an adjustable structure, which can flexibly adjust the limit spacing according to the width of the sheet material, further improving the versatility of the equipment. In addition, the discharge end of the second conveying device 12 can directly connect to external transfer equipment such as forklifts or AGVs to form a closed-loop logistics system, providing an efficient interface for subsequent multi-level subcontracting or warehousing management.

[0067] Please refer to Figure 1The sheet metal inspection, flipping, and stacking production equipment also includes a pallet loading mechanism 20 and a transfer frame 70. The pallet loading mechanism 20 includes a first slide rail 21 and a sliding frame 22 that slides along the first slide rail 21. The upper end of the sliding frame 22 is used to place the bottom tray. The robotic transfer mechanism 40 is also used to place the decorative panel on the transfer frame 70. The robotic transfer mechanism 40 is also used to place the bottom tray on the upper end of any one of the good product placement mechanism 10, the defective product placement rack 80, or the transfer frame 70. In the sheet metal inspection, flipping, and stacking production equipment, the pallet loading mechanism 20 drives the sliding frame 22 to move laterally through the first slide rail 21, accurately positioning the stacked bottom tray to the material picking station. The robotic transfer mechanism 40 uses a suction cup 43 to grab the bottom tray and flexibly place it on the upper end of the good product placement mechanism 10, the defective product placement rack 80, or the transfer frame 70 as a base for stacking decorative panels.

[0068] The transfer rack 70 serves as a temporary buffer unit for multi-level subcontracting. The robotic transfer mechanism 40 can temporarily store and secondary sort different grades of decorative panels (such as premium-grade panels). Combined with the dynamic placement of the base tray, it enables independent palletizing and batch management of multiple types of decorative panels. The multi-tasking capability of the robotic transfer mechanism 40 in the collaborative operation of decorative panels and base trays not only optimizes the continuity of the palletizing process but also balances the differences in sorting pace through the buffering effect of the transfer rack 70, avoiding production line congestion caused by different flow rates of good and defective products.

[0069] Please refer to Figure 3 The pallet feeding mechanism 20 also includes a second motor 231 fixed to the bottom of the sliding frame 22 and a traveling wheel 232 connected to the output shaft of the second motor 231. The traveling wheel 232 is driven by the second motor 231 to move along the first slide rail 21. At least two parallel second limiting bars 233 are provided on one side of the sliding frame 22. The sliding frame 22 drives the traveling wheel 232 to move directionally along the first slide rail 21 through the second motor 231, realizing the precise positioning and automatic feeding of the bottom pallet. The second limiting bars 233 physically limit the bottom pallet on the sliding frame 22, so that the bottom pallet can be accurately placed.

[0070] Please refer to Figure 4 The first conveying device 32 includes two spaced-apart second belt conveying assemblies 321, a drive shaft 322 that links the two second belt conveying assemblies 321, a swing frame 323 that swings around the drive shaft 322, a plurality of first rollers 325 mounted on the swing frame 323 via a rotating seat 324, and a first cylinder 326 that drives the swing frame 323 to swing; the rolling conveying direction of the first rollers 325 is perpendicular to the conveying direction of the second belt conveying assemblies 321.

[0071] Please refer to Figure 4 and Figure 5The detection and conveying mechanism 30 also includes a centering component 33, comprising a first limiting post 331, a second limiting post 332, and a cylinder linkage mechanism 333 that drives the two to move synchronously in opposite directions. The first limiting post 331 and the second limiting post 332 are located on both sides of the conveying direction of the first roller 325. The second belt conveying assembly 321 achieves synchronous conveying of the two belts through the drive shaft 322, while the first cylinder 326 drives the swing frame 323 to swing around the drive shaft 322, causing the first roller 325 to press down and contact the decorative panel. Utilizing the characteristic that the rolling direction of the first roller 325 is perpendicular to the second belt conveying assembly 321, the decorative panel is automatically turned from longitudinal to transverse conveying.

[0072] Please refer to Figure 4 The detection conveying mechanism 30 also includes a dust blowing assembly 34, which includes a second slide rail 341 fixed on the second bracket 31, a slider 342 sliding along the second slide rail 341, a belt driver 343 driving the slider 342, an air pipe 344 fixed on the slider 342, and a plurality of flat nozzles 345 inclined towards the detection area on the air pipe 344. The dust blowing assembly 34 drives the slider 342 to reciprocate along the second slide rail 341 via the belt driver 343, thereby driving the flat nozzles 345 on the air pipe 344 to perform dynamic sweeping dust blowing on the surface of the decorative panel entering the detection area; the flat nozzles 345 spray high-speed airflow at an inclined angle, effectively removing floating dust and debris from both sides of the decorative panel, avoiding secondary pollution caused by manual wiping or misjudgment caused by dust interference by the detection device 50. This component combines mobile purging with directional airflow to achieve full-area cleaning without blind spots, while also allowing for adjustment of purging speed and air pressure to adapt to different surface materials. This significantly improves detection accuracy and equipment environmental adaptability, while reducing downtime maintenance frequency.

[0073] Please refer to Figure 6 The robotic transfer mechanism 40 also includes clamping components 44 located on both sides of the suction cup frame 42, including grippers 441 rotatably mounted on the suction cup frame 42 and a fourth cylinder 442 driving the grippers 441 to rotate. The clamping components 44 drive the grippers 441 to rotate around the suction cup frame 42 via the fourth cylinder 442. While the suction cup 43 adsorbs the decorative panel, the grippers 441 flexibly clamp the edges of the panel from both sides, forming a dual fixation of air suction and mechanical clamping. This design can adapt to the stable gripping of large-sized or uneven decorative panels, preventing the panel from slipping or tilting due to airflow fluctuations or inertia during the transfer process. At the same time, the elastic contact surface of the grippers 441 avoids excessive clamping pressure that could cause indentations in the decorative paper, thus improving transfer accuracy and safety, and being compatible with the automated sorting needs of panels of different thicknesses and sizes.

[0074] Please refer to Figure 7The conveying and flipping mechanism 60 also includes a lifting device 64 mounted on the first support 61, multiple lifting frames 65 connected to the lifting device 64, and a roller 66 rotatably mounted on the lifting frame 65. The roller 66 can be raised and lowered between two adjacent rows of first belt conveyors 62, and its conveying direction is perpendicular to the first belt conveyor 62. The lifting device 64 drives the multiple lifting frames 65 to rise and lower synchronously, driving the roller 66 to rise to the gap between two adjacent rows of first belt conveyors 62. By utilizing the characteristic that the rotation direction of the roller 66 is perpendicular to the first belt conveyor 62, the decorative panel is switched from longitudinal conveying to transverse conveying to adjust its posture. This structure, through the lifting intervention of the roller 66 and the multi-directional conveying coordination, avoids surface scratches caused by the sliding friction of the board during the traditional flipping process, while ensuring the stability of posture adjustment for decorative panels of different sizes. This not only improves the flipping accuracy and efficiency but also reduces the mechanical complexity of the flipping device 63, achieving a seamless connection between flexible flipping and conveying.

[0075] Please refer to Figure 8 The flipping device 63 includes a first connecting rod 631 and a second connecting rod 632 rotatably mounted on a first bracket 61; a first swing seat 633 sleeved on the first connecting rod 631 and a second cylinder 634 driving its rotation; a first swing rod 635 fixed to the first connecting rod 631 and a second roller 636 rotatably mounted; a second swing seat 637 sleeved on the second connecting rod 632 and a third cylinder 638 driving its rotation; a second swing rod 639 fixed to the second connecting rod 632 and a third roller 630 rotatably mounted. When a flipping action is required, the second cylinder 634 and the third cylinder 638 drive the first swing seat 633 and the second swing seat 637 to rotate synchronously, which drives the second roller 636 and the third roller 630 at the ends of the first swing rod 635 and the second swing rod 639 to clamp the decorative panel from both sides and rotate with the connecting rod to achieve a 180° flip. The second roller 636 and the third roller 630 support the edge of the board through rolling contact. Combined with the cylinder, the flipping angle and clamping force are precisely controlled. This avoids the hard friction damage to the decorative paper caused by the traditional flipping mechanical grippers, and ensures that decorative panels of different sizes are subjected to uniform force and have a stable posture during the flipping process. The flipping and posture correction are completed simultaneously, which significantly improves the flipping efficiency and yield.
