Description

Technical Field

[0001] This invention relates to the field of furniture processing and inspection technology, and in particular to a multi-angle visual inspection device for furniture processing. Background Technology

[0002] Furniture is a three-dimensional appliance made from raw materials such as wood, engineered wood, metal, glass, leather, and plastic. It is used in homes, offices, and commercial spaces to meet the needs of sitting, lying down, placing items, storing, and decorating. Furniture components are three-dimensional workpieces. Traditional single-camera vision and manual visual inspection have many blind spots and shortcomings. Multi-angle vision equipment uses multiple sets of cameras to simultaneously image from the top, side, bottom, and oblique angles, capturing full-dimensional images of the workpiece at once. With multi-angle and multi-camera full coverage, it can simultaneously capture all surface defects such as chipped edges, scratches, bumps, edge banding delamination, glue overflow, pinholes, missing board material, and undrilled holes, preventing defective products from entering the assembly process.

[0003] Currently, the furniture manufacturing industry generally uses separate equipment with separate processing and inspection stations, lacking integrated devices that combine clamping, processing, and inspection. After milling and grooving, furniture wood needs to be transferred to an independent inspection table for secondary clamping. Multiple transfers not only lengthen the production cycle but also easily cause damage to the boards, adding new defects. Furthermore, defects can only be detected after all processing is complete. If defective boards flow into the assembly process, it will result in high rework and board scrap costs. Traditional furniture quality inspection only uses single-camera single-sided visual inspection or manual visual inspection. Furniture wood is a three-dimensional component, and there are imaging blind spots on the sides of the boards, the inner walls of the grooves, the top and bottom surfaces, and the rounded corners, leading to missed defects such as chipped edges, glue overflow, missed drilling holes, and minor scratches on the sides. The efficiency is high; manual flipping inspection is labor-intensive, the judgment standards are not uniform, long-term visual fatigue is easy, the inspection accuracy is unstable, and it is difficult to adapt to large-scale high-speed automated production lines; traditional furniture processing equipment has a single processing dimension, and longitudinal milling and transverse grooving require two independent machine tools to operate in steps. The workpiece needs to be disassembled and positioned multiple times, and multiple clamping will accumulate dimensional errors and reduce the assembly accuracy of furniture boards; at the same time, the processing mechanism is mostly fixed installation, which cannot be adapted to boards of different lengths and specifications by lateral displacement. The equipment has poor versatility, and enterprises need to purchase multiple processing equipment, resulting in high equipment investment costs in the workshop.

[0004] To address the aforementioned issues, a multi-angle visual inspection device for furniture processing is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this invention provides a multi-angle visual inspection device for furniture processing, aiming to improve the current furniture processing, which mostly uses separate equipment for processing and inspection. This results in workpieces being easily bumped during transport, and defect detection being delayed, leading to high rework and scrap costs. Traditional single-camera and manual inspection has a large number of visual blind spots, resulting in a high rate of missed detection and unstable inspection accuracy. Furthermore, the separate processing equipment and fixed mechanisms lead to accumulated dimensional errors from multiple clamping operations, resulting in poor versatility and high equipment and site investment costs.

[0024] The detection component 5 includes two support rods 501, which are fixedly connected to the rear side of the mounting frame 1. A fixing rod 503 is provided on the rear side of the two support rods 501. A movable plate 502 passes through the inner wall of the fixing rod 503.

The front end of the slide plate 505 is fixed to a connecting frame 508. Multiple detection rods 509 are vertically arranged inside the connecting frame 508. The multiple detection rods 509 simultaneously acquire images of the plate from multiple angles, including the top surface, oblique side, and side surface, avoiding blind spots in the three-dimensional workpiece imaging and completely capturing various appearance and dimensional defects of the plate.

[0026] A base 311 is installed on the top right side of the mounting plate 3, and a fixing rod 212 is fixedly installed on the inner wall of the base 311.

[0027] In this embodiment, a base 3 11 is fixedly assembled on the top right side of the mounting plate 3. A fixing rod 2 12 is horizontally fixedly installed inside the base 3 11. The fixing rod 2 12 extends laterally to the tail of the board and forms a front-to-back bidirectional limiting structure with the clamping block 606 of the clamping assembly 6. When the furniture wood 10 is clamped, the fixing rod 2 12 abuts against the end of the board and works with the clamping block 606 to clamp the front end of the board, preventing the workpiece from moving back and forth during the longitudinal and transverse milling and grooving process, stabilizing the single clamping processing accuracy, adapting to different length specifications of board and solid wood workpieces, and further improving the processing versatility of the equipment.

[0028] The adjustment component 4 includes a base 401, which is fixedly connected to the same side of the base plate 2. A test platform 402 is installed on the bottom of the inner wall of the base 401, and a test frame 403 is installed on the top of the inner wall of the test platform 402. Two placement plates 404 are fixedly connected to the inner side of the test frame 403, and slide rails 405 are slidably connected to the left and right ends of the rear side of the inner wall of the test frame 403.

[0029] In this embodiment, the base 401 is fixedly installed on the inner sides of the two base plates 2. The bottom of the inner cavity of the base 401 is equipped with a testing platform 402. A testing rack 403 is erected above the testing platform 402. Two placement plates 404 are fixed parallel to each other on the inner side of the testing rack 403 for temporarily placing the furniture wood 10 to be processed. The left and right ends of the rear side of the testing rack 403 are slidably equipped with slide rails 405, which can slide left and right to adjust the spacing of the placement plates 404, adapt to the pre-positioning of boards of different widths, and assist the clamping component 6 to quickly complete the loading, reduce the time spent on manual alignment, and shorten the overall production cycle.

[0030] The clamping assembly 6 includes a motor 601, which is fixedly connected to the top left side of the mounting plate 3. The output end of the motor 601 is fixedly connected to a drive wheel 602. A belt 603 is sleeved on the outer wall of the drive wheel 602.

Base 607 is mounted on the outside of adjusting rod 605 to provide rotation support. Motor 601 automatically drives clamping block 606 to clamp furniture wood 10. No manual fixing is required throughout the process. All processing and inspection procedures can be completed in a single clamping, avoiding the cumulative dimensional errors caused by multiple disassembly and assembly.

[0032] The longitudinal processing assembly 7 includes a connecting frame 2 701, which is fixedly connected to the top left side of the mounting frame 1. A motor 2 702 is fixedly connected to the rear end of the top left side of the connecting frame 2 701. A coupling 703 is fixedly connected to the output end of the motor 2 702. A drive wheel 2 704 is fixedly connected to the top inner wall of the coupling 703. A belt 2 705 is sleeved on the outer wall of the drive wheel 2 704. A driven wheel 2 706 is sleeved on the right side of the belt 2 705. Driven wheels 3 712 are sleeved on both the front and rear sides of the inner wall of the belt 2 705.

[0033] In this embodiment, the second connecting frame 701 is fixed to the upper left of the mounting frame 1. The second motor 702 is assembled at the left rear end of the second connecting frame 701. The output end of the second motor 702 is connected to the second drive wheel 704 via the coupling 703. The second drive wheel 704 synchronously drives the second driven wheel 706 and two sets of third driven wheels 712 via the second belt 705. The third driven wheel 712 has a fixed connecting shaft 708 inside. The first moving frame 709 is slidably assembled outside the first connecting shaft 708. The moving frame 709 rises and falls along the two limit rods 707. The moving frame 709 has a built-in third motor 710. The third motor 710 drives the first processing block 711 to complete the longitudinal milling operation of the furniture wood 10. The independent longitudinal cutting unit enriches the processing capability of the equipment.

[0034] The transverse processing component 9 includes two slide blocks 901, which are fixedly connected to the left and right ends of the rear side of the connecting frame 701. A slide rod 902 is slidably connected to the inner wall of the slide block 901. A motor 903 is fixedly connected to the top rear end of the slide rod 902. A drive wheel 904 is fixedly connected to the output end of the motor 903. A belt 905 is sleeved on the outer wall of the drive wheel 904. A driven wheel 906 is sleeved on the inner wall of the belt 905. A connecting shaft 907 is fixedly connected to the inner wall of the driven wheel 906. A processing block 908 is fixedly connected to the right side of the connecting shaft 907.

[0035] In this embodiment, two sets of slide blocks 901 are symmetrically fixed at the left and right ends of the rear side of the connecting frame 2 701. The slide block 901 is vertically slidably mounted with a slide rod 902 inside. The top of the rear end of the slide rod 902 is equipped with a motor 5 903. The output end of the motor 5 903 is connected to the drive wheel 3 904. The drive wheel 3 904 is driven by the driven wheel 4 906 via the belt 3 905. The driven wheel 4 906 is fixedly connected to the shaft 2 907 inside. The right end of the shaft 2 907 is equipped with a processing block 2 908. The processing block 2 908 completes the transverse grooving operation of the furniture wood 10. The longitudinal and transverse processing units are integrated into one unit. A single device replaces two independent processing machine tools, reducing equipment procurement and workshop floor space costs.

[0036] The moving component 8 includes two motors 801, both of which are fixedly connected to the bottom of the front and rear sides of the connecting frame 701. The output end of the motors 801 is fixedly connected to a gear 802, and the left end of the front and rear sides of the connecting frame 701 is fixedly connected to a rack 803. Multiple moving wheels 804 are fixedly connected to the inner wall of the connecting frame 701.

[0037] In this embodiment, two motors 801 are fixed to the front and rear bottom of the connecting frame 701 respectively. The output shaft of the motor 801 is equipped with a gear 802. The front and rear left ends of the mounting frame 1 are fixed with racks 803. The gears 802 and racks 803 mesh and transmit power. Multiple sets of moving wheels 804 are evenly installed on the inner wall of the connecting frame 701 to reduce translational friction resistance. The motor 801 drives the entire set of longitudinal processing components 7 and transverse processing components 9 to move laterally synchronously. It can freely adapt to furniture wood 10 with large differences in length, without changing the equipment model, and is suitable for the transformation of small and medium-sized furniture automated production lines.

[0038] The movable plate 502 passes through the inner wall of the two support rods 501, and the two slide rails 506 are fixedly connected to the front side of the support rods 501. This design allows the movable plate 502 to pass horizontally through the interior of the two support rods 501, enabling the overall forward and backward translational coarse adjustment of the detection mechanism. The two slide rails 506 are horizontally fixed to the front side of the support rods 501, and the slide rails 506 define the horizontal sliding trajectory of the slider 507. The slide plate 505 relies on the slider 507 to finely adjust the lateral position of the detection rods 509 along the slide rails 506. Through bidirectional adjustment in the forward and backward and left and right directions, multiple detection rods 509 can be accurately aligned with the sides of the plate, the inner wall of the groove, the rounded corners, and other areas that are prone to being missed. Multi-angle synchronous imaging completely eliminates the blind spots of single-camera visual inspection and reduces the rate of missed defects in the plate.

[0039] Both limiting rods 707 are fixedly connected to the front and rear ends of the inner side of the connecting frame 2 701, and both connecting shafts 1 708 are rotatably connected to the front and rear ends of the outer side of the connecting frame 2 701. The processing block 1 711 performs longitudinal processing on the furniture wood 10. This design is to fix the two limiting rods 707 in parallel to the front and rear ends of the inner side of the connecting frame 2 701, and rotatably assemble the two connecting shafts 1 708 on the front and rear ends of the outer side of the connecting frame 2 701. The moving frame 709 moves vertically up and down along the limiting rods 707. The limiting rods 707 limit the maximum travel of the moving frame 709 to prevent the processing block 1 711 from exceeding its travel and hitting the furniture wood 10, causing damage to the workpiece. After the longitudinal processing is completed, the detection component 5 scans the longitudinal processing dimensions of the board at the same time. If there is a deviation in milling depth or width, the workpiece does not need to be unloaded and transferred. The longitudinal processing component 7 is restarted in place to correct the deviation, reducing the scrap loss of the board.

[0040] The second connecting shaft 907 is rotatably connected to the top front end of the slide rod 902. The second processing block 908 performs transverse processing on the furniture wood 10. This design allows the second connecting shaft 907 to be rotatably assembled at the front end of the slide rod 902. The slide rod 902 slides vertically along the slide seat 901 to adjust the processing height. The second processing block 908 moves up and down with the slide rod 902 to complete transverse grooving of different depths in the furniture wood 10. The transverse grooving and longitudinal milling processes can be completed continuously. After processing, the post-detection component 5 immediately starts full-area visual scanning to identify defects such as grooving offset, edge chipping, and glue overflow. Defective workpieces are kept in a clamped and fixed state, and the transverse processing component 9 is directly restarted to repair the defects, eliminating the need for repeated clamping and transfer steps and greatly improving the production line flow efficiency.

[0041] Working principle: Workpiece pre-placement and loading positioning: The operator places the furniture wood 10 to be processed on the placement plate 404 of the adjustment component 4. The placement plate 404 is mounted on the inspection frame 403. The inspection frame 403 can slide left and right along the slide rail 1 405 to adjust the width to adapt to different widths of boards. After the pre-positioning is completed, the board is pushed to the clamping station. The base 3 11 and the fixing rod 2 12 abut against the tail of the board to complete the end limit, providing a reference for the precise clamping of the clamping component 6, reducing the difficulty of manual alignment, and improving the versatility of the corresponding equipment.

[0042] The automatic clamping and locking mechanism activates the clamping assembly 6 motor 601. The power output of motor 601 is transmitted to the driven wheel 604 via drive wheel 602 and belt 603, causing the adjusting rod 605 to extend forward. The clamping block 606 presses the front end of the furniture wood 10, and the base 607 provides rotational support for the adjusting rod 605, achieving stable locking of the board in both front and rear directions. After a single clamping, the board is fixed in place throughout the process, eliminating the need for multiple disassemblies and avoiding the cumulative dimensional errors caused by multiple positioning. At the same time, it eliminates the material handling and transfer process between processing and inspection stations, realizing the beneficial effect of integrated production efficiency.

[0043] The moving component adaptively adjusts to fit the length of the board. The two motors 801 of the moving component 8 are activated. The motors 801 drive the gears 802 to mesh with the racks 803 on both sides of the mounting frame 1. With the help of the moving wheels 804, the sliding resistance is reduced, and the connecting frame 701 is driven to move laterally as a whole. The connecting frame 701 simultaneously drives the longitudinal processing component 7 and the transverse processing component 9 to move synchronously. The position of the processing mechanism is adjusted according to the actual length of the furniture wood 10. It can adapt to both long and short boards without the need to replace special equipment, thus solving the pain points of fixed installation and poor versatility of traditional processing equipment.

[0044] The longitudinal and transverse integrated milling and grooving process begins by starting the longitudinal machining component 7 motor 2 702. Power is transmitted to the connecting shaft 1 708 via coupling 703 and belt 2 705. The moving frame 709 moves vertically up and down along the limit rod 707, and motor 3 710 drives machining block 1 711 to complete the longitudinal milling of the plate. After the longitudinal machining is completed, the transverse machining component 9 motor 5 903 is started. The drive wheel 3 904 drives the connecting shaft 2 907 via belt 3 905. The slide rod 902 adjusts the grooving height up and down along the slide block 901, and machining block 2 908 completes the transverse grooving operation. A single machine can simultaneously complete bidirectional cutting, replacing two separate machining tools and reducing equipment purchase and site occupation costs.

[0045] Multi-angle visual full-area defect detection: After all processing steps are completed, the rear-mounted detection component 5 starts full-area scanning. The operator rotates the moving plate 502 to adjust the front and rear distance of the detection mechanism. The sliding plate 505 performs fine-tuning left and right along the slide rails 2 504 and 3 506. The connecting frame 1 508 carries multiple detection rods 509. Each detection rod 509 is an integrated visual acquisition unit. The rod body integrates a high-definition industrial camera, a ring shadowless light source, and a laser range sensor from top to bottom. The entire set of components is fixed in the mounting slot of the connecting frame 1 508. The connecting frame 1 508 adopts a modular slot design, which can freely increase or decrease the number of detection rods 509 to adapt to the inspection needs of large boards, narrow strips, and curved and irregularly shaped furniture wood 10. The ring light source surrounds the camera lens and can independently adjust the brightness. For reflective materials such as painted, PET film, and solid wood, layered supplementary lighting is provided to avoid the reflective blind spots caused by strong light from a single angle. The laser range sensor collects real-time data on the board material and the detection rods 509. The vertical distance; multi-directional imaging avoids the blind spots of traditional single-camera detection, and simultaneously identifies all appearance and size defects such as chipped edges, scratches, missed drill holes, slot offsets, and excess glue, solving the problems of high missed detection rate and unstable accuracy of manual and single-camera detection.

[0046] Defects are corrected in situ during secondary processing. Qualified workpieces are unloaded. If the detection component 5 identifies a processing defect in the sheet metal, the equipment does not need to loosen the workpiece or transfer it for unloading. Instead, it directly starts the corresponding longitudinal processing component 7 or transverse processing component 9 for secondary cutting correction in situ. After correction, the detection component 5 is started again for re-inspection until all indicators of the sheet metal are qualified. If no defects are detected, the clamping component 6 motor 601 reverses to retract the clamping block 606. The operator removes the finished sheet metal and enters the next workpiece processing cycle.

[0047] The entire process integrates clamping, processing, and inspection functions. All processes can be completed in one clamping of the workpiece. Multi-angle inspection has no blind spots. The processing mechanism can adapt to multiple specifications of boards and can also achieve on-site defect repair. It solves the industry pain points of existing furniture processing equipment from three dimensions: production cycle, quality inspection accuracy, and equipment versatility, and significantly reduces the overall production cost of labor, materials, and equipment procurement.
