Description

Technical Field

[0001] The present invention relates to the technical field of aluminum floor processing machinery, in particular to an automated production line and processing method for rough angle milling and surface milling of aluminum floors. Background Art

[0002] In the aluminum flooring manufacturing process, rough angle milling (referring to the preliminary chamfering or shaping of the side edges of the aluminum flooring blank) and surface milling (referring to the surface processing such as thickness calibration, leveling, or grooving of the aluminum flooring blank) are two key and usually separate pre-processes. Currently, the industry generally uses separate rough angle milling machines and surface milling machines to perform these two operations. The existing technology has the following significant drawbacks:

[0003] 1. The equipment is scattered and occupies a large space: Two independent processing equipment (rough milling machine and surface milling machine) are required. Not only is the equipment procurement cost high, but it also takes up a large amount of production workshop space, which is especially disadvantageous for small and medium-sized enterprises with limited space. The material flow area between the equipment also further increases the space demand.

[0004] 2. Low production efficiency and long circulation time: Aluminum flooring requires multiple manual or semi-automatic handling, positioning, clamping and unloading between two devices. This process is not only time-consuming and increases the processing cycle of a single product, but also significantly reduces overall production efficiency and becomes a bottleneck of the production line.

[0005] 3. Repeated positioning errors affect accuracy: When transferring aluminum flooring between the roughing and milling machines, it inevitably requires repositioning and re-clamping. Multiple re-clamping can easily lead to the accumulation of positioning reference errors, making it difficult to ensure the relative position accuracy of the roughing and milling processes, which directly affects the assembly quality and aesthetics of the final aluminum flooring product.

[0006] 4. High labor costs and low degree of automation: Operating two devices usually requires more operators, or requires operators to frequently switch between the two devices, which increases labor costs and labor intensity. At the same time, the degree of automation and continuity of the entire process is low.

[0007] 5. The process connection is not smooth: the separated processes lead to the fragmentation of the production process, making it difficult to achieve continuous and efficient assembly line operations, and increasing the complexity of production management.

[0008] 6. Complex and inefficient aluminum chip collection system: Two independent devices need to be equipped with a set of aluminum chip collection devices (such as dust suction ports, pipes and collection tanks), which not only increases equipment costs and maintenance workload, but also the scattered collection points may lead to insufficient suction, complex pipe layout, flying aluminum chips and other problems, affecting the cleanliness of the workshop environment and the health of workers. Dust accumulation also poses a safety hazard. In particular, for the problem of aluminum chip collection, the existing separation equipment solution has inherent shortcomings:

[0009] Due to the different structures of the two machines, the direction of tool movement (rough milling is usually parallel to the crossbeam of the machine's gantry support, while surface milling is usually perpendicular to the crossbeam), and the different locations where aluminum chips are generated, it is very difficult to design an efficient, non-interfering aluminum chip collection system that covers all processing areas. This usually requires the installation of multiple collection troughs and suction ports in different locations, resulting in a complex structure and uneven dust collection, making it difficult to achieve uniform, efficient, and dust-free collection of aluminum chips. Summary of the Invention

[0010] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing technology, an automated production line and processing method for rough milling and milling of aluminum floors are provided, which can effectively integrate the rough milling and milling functions, and solve the core problems of equipment dispersion, low efficiency, difficult precision control, and difficulty in collecting aluminum chips. Innovative processing equipment is provided to achieve efficient, compact, high-precision and environmentally friendly production of aluminum floors in the front-end process.

[0011] The technical solution adopted by the present invention to solve the technical problem is: an automated processing method for rough milling of angles and milling of surfaces of aluminum floors, comprising the following steps:

[0012] Step 1: The aluminum floor to be processed is transferred to the rough milling angle input waiting area of ​​the rough milling angle equipment by the first manipulator structure;

[0013] Step 2: The rough milling equipment moves the aluminum floor to the elevated rough milling processing area, where it is clamped by the first aluminum floor fixture and moves along the first slide rail. The rough milling cutters on both sides simultaneously complete the rough milling process.

[0014] Step 3: The processed aluminum floor is transferred to the rough milling output transfer area and transferred to the second aluminum floor fixing device of the milling equipment through the second robot structure;

[0015] Step 4: The milling equipment drives the aluminum floor to move along the second slide rail, and the milling tool completes the surface processing;

[0016] Step 5: Use the third robot structure to move the milled aluminum floor to the unloading area.

[0017] Since traditional separate equipment needs to be equipped with independent aluminum chip collection devices and requires two sets of dust suction devices, the equipment cost is high, the pipeline layout is complicated, the space occupied is large, the suction dispersion leads to uneven collection efficiency, and aluminum chips are easy to fly and pollute the environment. Therefore, the present invention further stipulates that in the above technical scheme, the aluminum chips generated in the rough milling of angles and milling of surfaces are captured at the source by the first aluminum chip collection trough and the second aluminum chip collection trough respectively, and are collected to the same negative pressure dust suction device through branch pipes for unified treatment. The first aluminum chip collection trough and the second aluminum chip collection trough directly below the processing point are used to directly capture the aluminum chips generated in the rough milling of angles and milling of surfaces, so as to avoid the aluminum chips from spreading to other areas and ensure cleanliness from the source. The branch pipes are collected to the same negative pressure dust suction device, and the two collection tanks share a single negative pressure device to reduce procurement costs. The branch pipes replace the two sets of independent pipes, saving installation space and maintenance costs. The concentrated negative pressure ensures balanced suction and avoids the problem of insufficient suction in the traditional decentralized system.

[0018] The present invention also provides a production line for realizing an automated processing method for rough milling and milling surface of aluminum floor, comprising a gantry bracket, wherein two transverse guide rails are arranged in parallel on the crossbeam of the gantry bracket, wherein a first manipulator structure is slidably arranged at one end of one of the transverse guide rails, a second manipulator structure is slidably arranged at the other end, and a third manipulator structure is slidably arranged on the other transverse guide rail, and a rough milling device for rough milling of the aluminum floor and a milling device for milling surface of the aluminum floor are installed below the gantry bracket, the movement direction of the rough milling device for fixing the aluminum floor component is parallel to the crossbeam of the gantry bracket, and the movement direction of the milling device for fixing the aluminum floor component is parallel to the crossbeam of the gantry bracket. The moving direction is perpendicular to the crossbeam of the gantry support; the first manipulator structure transfers the aluminum floor to be processed to the rough milling device, the second manipulator structure transfers the aluminum floor after rough milling to the milling device, and the third manipulator structure moves the aluminum floor after milling; the rough milling device includes a first aluminum chip collecting trough corresponding to the processing area of ​​the rough milling device and used to collect aluminum chips generated by rough milling, and the milling device includes a second aluminum chip collecting trough corresponding to the processing area of ​​the milling device and used to collect aluminum chips generated by milling, and the first aluminum chip collecting trough and the second aluminum chip collecting trough are both provided with a dust suction port, and the dust suction port is connected to the negative pressure dust suction device through a pipe.

[0019] Since in traditional equipment, aluminum chips splash from the processing area to the area to be processed or the processed area, contaminating the semi-finished products, and the manipulator needs to cross the processing area in the plane layout to operate, affecting the processing safety and continuity, and the plane layout causes the aluminum chips to scatter over a large range, making it difficult to capture them in a centralized manner, the present invention further specifically defines that in the above technical solution, the rough milling angle equipment includes a working platform, one end of the working platform close to the first manipulator structure is a rough milling angle input waiting area, the end of the working platform close to the second manipulator structure is a rough milling angle output transfer area, and the middle of the working platform is The rough milling angle processing area is elevated by a supporting structure so that the horizontal height of the rough milling angle processing area is higher than the rough milling angle input waiting area and the rough milling angle output transfer area; the rough milling angle input waiting area, the rough milling angle processing area, and the rough milling angle output transfer area are arranged linearly to reduce the moving distance of the robot; the high-position design of the rough milling angle processing area allows aluminum chips to fall directly into the first aluminum chip collection trough to avoid debris contamination of the rough milling angle input waiting area and the rough milling angle output transfer area; the rough milling angle output transfer area serves as a buffer zone between the rough milling angle and the milling surface processes to eliminate production line blockages caused by equipment rhythm differences.

[0020] In order to solve the technical problem that the aluminum floor is easily deviated from the preset processing direction when moved manually or mechanically, affecting the symmetry of the bilateral chamfering, and the technical problem that traditional equipment needs to process the corners on both sides twice, which doubles the time, the present invention further specifically defines that in the above technical scheme, the rough milling processing area includes a first support frame fixed on the working platform, a first slide rail horizontally mounted on the first support frame and parallel to the crossbeam of the gantry bracket, a first aluminum floor fixing device slidingly set at the bottom of the first slide rail, and rough milling tools symmetrically set on both sides of the first slide rail; the first slide rail is forcibly limited to be parallel to the crossbeam to ensure the consistency of the rough milling processing direction; the bilateral rough milling tools operate synchronously, and the bilateral chamfering is completed in a single processing.

[0021] In order to solve the technical problems that traditional independent milling machines need to reserve space for lateral movement, which aggravates the site shortage, and the technical problems that the milling tool is located at a high position, aluminum chips freely fall and spread, and are difficult to capture in full, the present invention further specifically defines that in the above technical scheme, the milling equipment includes a frame, a second support frame fixed on the frame, a third support frame fixed on the frame, a second slide rail horizontally mounted on the second support frame and perpendicular to the crossbeam of the gantry support, a second aluminum floor fixing device slidably arranged on the top of the second slide rail, and a tool mounting seat mounted on the third support frame and located above the second slide rail, a milling tool is installed on the tool mounting seat, and the second aluminum chip collection trough is located below the milling tool; the second slide rail is arranged perpendicular to the crossbeam, and the equipment footprint is reduced; the second aluminum chip collection trough is directly below the milling tool, and the aluminum chip collection efficiency is doubled.

[0022] In order to solve the technical problem of inconsistent milling surface depth or flatness caused by fluctuations in the speed of ordinary motors, the present invention further specifically stipulates that in the above technical solution, the milling tool is driven by an AC permanent magnet servo motor, thereby achieving high-precision driving of the milling tool.

[0023] In order to overcome the technical problem that excessive fixing pressure may easily leave indentations on the side of the aluminum floor and the technical problem that traditional clamps cannot quickly adapt to aluminum floors of different widths, the present invention further specifically defines that, in the above technical solution, the second aluminum floor fixing device includes a base plate connected to the top slider of the second slide rail and adjustable side pressure cylinders symmetrically arranged on both sides of the base plate. The cylinder stroke is intelligently controlled and the pressure is automatically released when overloaded to avoid indentations on the aluminum floor.

[0024] In order to overcome the technical problems of machining coordinate system offset caused by position deviation of manual loading and unloading and the technical problem that single-axis or dual-axis manipulators cannot cover the three-dimensional working space, the present invention further specifically defines that, in the above technical scheme, the first manipulator structure, the second manipulator structure and the third manipulator structure all include an X-axis drive device, a Y-axis drive device and a Z-axis drive device; the X-axis drive device is slidably arranged on the transverse guide rail to realize horizontal movement along the direction of the gantry bracket beam; the Y-axis drive device is installed on the X-axis drive device to realize horizontal movement perpendicular to the direction of the beam; the Z-axis drive device is installed on the Y-axis drive device to realize lifting movement perpendicular to the plane of the aluminum floor; the XYZ three-axis linkage realizes precise grasping of any point in space, solving the position deviation of manual loading and unloading.

[0025] To overcome the technical issues of traditional independent equipment requiring two sets of dust collection devices and the technical problem of traditional decentralized collection leading to excessive PM10 concentration in the workshop, the present invention further specifically stipulates that in the above technical solution, the first and second aluminum chip collection troughs are connected to the same main air duct via a branch pipe, the main air duct is connected to the negative pressure dust collection device, and a cyclone separator and dust collection box are provided at the end of the main air duct. The two collection troughs share a single negative pressure dust collection device, which reduces equipment procurement costs and energy consumption; the branch pipe replaces the two independent pipes, reducing installation and maintenance costs; the cyclone separator pre-processes large aluminum chips, and the sealed design of the dust collection box greatly reduces PM10 concentration in the work area.

[0026] The beneficial effects of the present invention are as follows: the present invention provides an automated production line and processing method for rough milling of aluminum floors, which realizes efficient, continuous, and automated production of rough milling of aluminum floors and milling of aluminum floors through an innovative gantry support integrated layout, three independent and coordinated manipulators, an optimized equipment structure design, an efficient source aluminum chip collection system, and a highly flexible fixing and driving method. At the same time, it significantly improves space utilization, environmental friendliness, operational safety, and equipment adaptability, and specifically includes the following advantages:

[0027] 1. Efficient and continuous automated production: Through the independent and coordinated movement of the first, second, and third manipulator structures on the gantry support beam guide rail, the entire process of aluminum flooring, from rough milling angle input, rough milling angle processing, rough milling angle output, to milling surface input, milling surface processing, and unloading, is automated. The manipulators have clear division of labor: the first manipulator structure loads the rough milling angle, the second manipulator structure transfers to the milling surface, and the third manipulator structure unloads the material. These parallel operations significantly improve production efficiency and continuity.

[0028] 2. Compact and optimized spatial layout: The rough milling equipment for the beams parallel to the movement direction and the surface milling equipment for the beams perpendicular to the movement direction are integrated and arranged under the gantry support. The guide rails on the beams of the gantry support carry the movement of all manipulators, making full use of the three-dimensional space. This layout greatly reduces the overall equipment footprint.

[0029] 3. Efficient and environmentally friendly collection of aluminum chips at the source: The rough milling equipment and surface milling equipment are each equipped with a dedicated aluminum chip collection trough. The rough milling equipment is equipped with a first aluminum chip collection trough, and the surface milling equipment is equipped with a second aluminum chip collection trough. These troughs are located directly below the processing area to capture aluminum chips at the source. Both collection troughs are equipped with dust suction ports and are connected to negative pressure dust collection devices via pipes, forming a centralized and efficient dust removal system. This effectively improves the working environment, reduces dust pollution, protects worker health, and facilitates the centralized recovery and processing of aluminum chips.

[0030] 4. Optimized design of rough milling equipment to improve efficiency and isolation: The work platform is clearly divided into a rough milling input waiting area, a rough milling output transfer area, and a rough milling processing area. The rough milling processing area is elevated, allowing the rough milling input waiting area, the rough milling output transfer area, and the rough milling processing area to be separated in height, making it easier for the robot to operate in the non-processing area and reducing interference with the processing process. It also provides a more direct and effective space for collecting aluminum chips below the rough milling processing area, making it easier for aluminum chips to fall into the collection trough.

[0031] 5. Equipment versatility and flexibility: The aluminum floor fixing devices on the rough milling equipment and the surface milling equipment are all equipped with a structure with an adjustable side pressure cylinder, which enables the equipment to adapt to the processing requirements of aluminum floors of different sizes and specifications, thereby improving the versatility and flexibility of the production line;

[0032] 6. High-precision and reliable milling: The milling cutter is driven by an AC permanent magnet servo motor, which provides precise speed control and stable power output, which helps to ensure the quality and accuracy of milling.

[0033] 7. High flexibility and precise positioning of the manipulator: All manipulators are equipped with X, Y, and Z three-axis drive capabilities. The X-axis moves along the beam, covering the length direction of the equipment; the Y-axis moves perpendicular to the beam, covering the width direction of the equipment; the Z-axis rises and falls to achieve material loading and unloading. This structure provides great movement flexibility and spatial coverage capabilities, ensuring that the manipulator can accurately locate at each station of the equipment for loading and unloading operations.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] See Figure 1 The present invention provides an automated processing method for rough milling of aluminum flooring and milling of the surface, comprising the following steps:

[0044] Step 1: The aluminum floor to be processed 700 is transferred to the rough milling input waiting area 503 of the rough milling equipment 500 by the first robot structure 200;

[0045] Step 2: The rough milling equipment 500 moves the aluminum floor 700 to the elevated rough milling processing area 505, where it is clamped by the first aluminum floor fixture 508 and moves along the first slide rail 507. The double-sided rough milling tool 509 simultaneously completes the double-sided rough milling process.

[0046] Step 3: The processed aluminum floor 700 is transferred to the rough milling output transfer area 504 and transferred to the second aluminum floor fixing device 606 of the milling equipment 600 by the second robot structure 300;

[0047] Step 4: The milling device 600 drives the aluminum floor 700 to move along the second slide rail 605, and the milling tool 608 completes the surface processing;

[0048] Step 5: Use the third robot structure 400 to move the milled aluminum floor 700 to the unloading area.

[0049] Aluminum chips generated during rough angle milling and surface milling are captured at the source by the first and second aluminum chip collection troughs 501 and 601, respectively, and then collected via branch pipes to the same negative pressure dust collection device for unified treatment. The first and second aluminum chip collection troughs 501 and 601, located directly below the processing points, directly capture aluminum chips generated during rough angle milling and surface milling, preventing them from spreading to other areas and ensuring cleanliness at the source. Branch pipes converge into the same negative pressure dust collection device, allowing both collection troughs to share a single negative pressure device, reducing procurement costs. Branch pipes replace two sets of independent piping, saving installation space and maintenance costs. Centralized negative pressure ensures balanced suction, avoiding the problem of insufficient suction in traditional decentralized systems.

[0050] The rough milling area 505 is designed to be elevated, allowing aluminum chips to fall directly into the first aluminum chip collection trough 501, preventing contamination of the input waiting area 503 and the output transfer area 504. The aluminum floor is secured with an adjustable side-pressure cylinder. Through intelligent stroke control, the cylinder automatically releases pressure in the event of an overload, preventing indentations on the aluminum floor.

[0051] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The present invention provides an automated production line for rough milling and surface milling of aluminum floors, comprising a gantry bracket 100. Two transverse guide rails are arranged in parallel on the crossbeam of the gantry bracket 100. A first manipulator structure 200 is slidably arranged at one end of one of the transverse guide rails, and a second manipulator structure 300 is slidably arranged at the other end. A third manipulator structure 400 is slidably arranged on the other transverse guide rail. A rough milling device 500 for rough milling the aluminum floor 700 and a surface milling device 600 for surface milling the aluminum floor 700 are installed below the gantry bracket 100.

[0052] The movement direction of the rough milling device 500 for fixing the aluminum floor 700 is parallel to the crossbeam of the gantry bracket 100 , and the movement direction of the surface milling device 600 for fixing the aluminum floor 700 is perpendicular to the crossbeam of the gantry bracket 100 .

[0053] The first robot structure 200 transfers the aluminum floor 700 to be processed to the rough milling equipment 500, the second robot structure 300 transfers the aluminum floor 700 after rough milling to the milling equipment 600, and the third robot structure 400 removes the aluminum floor 700 after milling.

[0054] The rough angle milling device 500 includes a first aluminum chip collecting trough 501 corresponding to a processing area of ​​the rough angle milling device 500 and used for collecting aluminum chips generated by the rough angle milling process.

[0055] The milling device 600 includes a second aluminum chip collecting trough 601 corresponding to the processing area of ​​the milling device 600 and used to collect aluminum chips generated by the milling process.

[0056] The first aluminum chip collecting trough 501 and the second aluminum chip collecting trough 601 are both provided with dust suction ports, which are connected to the negative pressure dust suction device through pipes.

[0057] Among them, the rough milling angle equipment 500 includes a working platform 502, the end of the working platform 502 close to the first manipulator structure 200 is a rough milling angle input waiting area 503, the end of the working platform 502 close to the second manipulator structure 300 is a rough milling angle output transfer area 504, and the middle part of the working platform 502 is a rough milling angle processing area 505. The rough milling angle processing area 505 is elevated by a supporting structure so that the horizontal height of the rough milling angle processing area 505 is higher than the rough milling angle input waiting area 503 and the rough milling angle output transfer area 504. The rough milling angle input waiting area 503, the rough milling angle processing area 505, and the rough milling angle output transfer area 504 are arranged in a linear manner to reduce the moving distance of the robot; the rough milling angle processing area is designed to be high-positioned so that aluminum chips fall directly into the first aluminum chip collecting trough 501, avoiding debris contamination of the rough milling angle input waiting area 503 and the rough milling angle output transfer area 504; the rough milling angle output transfer area 504 serves as a buffer zone between the rough milling angle and the milling surface process, eliminating production line blockages caused by equipment beat differences.

[0058] The roughing angle milling area 505 includes a first support frame 506 fixed to the work platform 502, a first slide rail 507 mounted horizontally on the first support frame 506 and parallel to the crossbeam of the gantry support 100, a first aluminum floor fixture 508 slidingly mounted at the bottom of the first slide rail 507, and roughing angle milling tools 509 symmetrically positioned on either side of the first slide rail 507. The first slide rail 507 is constrained to be parallel to the crossbeam to ensure consistent roughing angle milling direction. The roughing angle milling tools 509 on both sides operate synchronously, completing double-sided chamfering in a single operation.

[0059] A detachable protective panel 510 is provided at the roughing angle processing area 505. The detachable protective panel 510 can play a protective role when the roughing angle processing area 505 is working, and can quickly complete the replacement of the roughing angle cutting tool 509 when the roughing angle processing area 505 is stopped.

[0060] The first aluminum floor fixing device 508 includes a base plate connected to the bottom slider of the first slide rail 507 and adjustable side pressure cylinders symmetrically arranged on both sides of the base plate. The cylinder stroke is intelligently controlled and automatically releases pressure when the pressure is overloaded to avoid indentation of the aluminum floor 700.

[0061] The milling equipment 600 includes a frame 602, a second support frame 603 fixed to the frame 602, a third support frame 604 fixed to the frame 603, a second slide rail 605 mounted horizontally on the second support frame 603 and perpendicular to the crossbeam of the gantry support 100, a second aluminum floor fixture 606 slidably mounted on the top of the second slide rail 605, and a tool mounting base 607 mounted on the third support frame 604 and located above the second slide rail 605. A milling tool 608 is mounted on the tool mounting base 607, and a second aluminum chip collection trough 601 is located below the milling tool 608. The second slide rail 605 is arranged perpendicular to the crossbeam, reducing the equipment's footprint; the second aluminum chip collection trough 601 is located directly below the milling tool 608, doubling the efficiency of aluminum chip collection.

[0062] The milling tool 608 is driven by an AC permanent magnet servo motor 609 , thereby achieving high-precision driving of the milling tool 608 .

[0063] The second aluminum floor fixing device 606 includes a base plate connected to the top slider of the second slide rail 605 and adjustable side pressure cylinders symmetrically arranged on both sides of the base plate. The cylinder stroke is intelligently controlled and automatically releases pressure when the pressure is overloaded to avoid indentation of the aluminum floor 700.

[0064] The first, second, and third manipulator structures 200, 300, and 400 all include X-, Y-, and Z-axis drives. The X-axis drive slides on a transverse guide rail, enabling horizontal movement along the crossbeam of the gantry support 100. The Y-axis drive is mounted on the X-axis drive, enabling horizontal movement perpendicular to the crossbeam. The Z-axis drive is mounted on the Y-axis drive, enabling vertical movement perpendicular to the plane of the aluminum floor 40. This three-axis linkage enables precise grasping of any point in space, addressing positional deviations in manual loading and unloading.

[0065] The first and second aluminum chip collection troughs 501 and 601 are connected to the same main air duct via branch pipes. This main duct is connected to a negative pressure dust collection device, and at the end of the main duct, a cyclone separator and dust collection box are installed. Both collection troughs share a single negative pressure dust collection device, reducing equipment procurement costs and energy consumption. The branch pipes replace two independent piping systems, reducing installation and maintenance costs. The cyclone separator pre-processes large aluminum chips, and the sealed dust collection box significantly reduces PM10 concentration in the work area.

[0066] The working principle of the automated production line and processing method for rough milling and milling of aluminum floor is as follows: the first manipulator structure 200 moves along the transverse guide rail of the gantry support 100 and grabs a piece of aluminum floor to be processed 700 from a preset loading position. The first manipulator structure 200 accurately positions the aluminum floor 700 through its X, Y, and Z axis drive devices and places the aluminum floor 700) into the rough milling angle input waiting area 503 of the rough milling angle device 500. The rough milling angle device 500 moves the aluminum floor 700 located in the rough milling angle input waiting area 503 to the elevated rough milling angle processing area 505. In the corner processing area 505, the aluminum floor 700 is firmly clamped by the first aluminum floor fixing device 508 at the bottom of the first slide rail 507. The fixed aluminum floor 700 moves along the first slide rail 507. The rough milling of the edges and corners of the aluminum floor 700 is completed by the rough milling angle cutters 509 symmetrically arranged on both sides. The detachable protective panel 510 provides safety protection during processing. The aluminum chips generated by the processing fall directly into the first aluminum chip collection trough 501 located below the rough milling angle processing area 505. After the rough milling angle processing is completed, the aluminum floor 700 is transferred to the rough milling angle output transfer of the rough milling angle equipment 500. In area 504, the second manipulator structure 300 moves along the transverse guide rail of the gantry support 100 and locates at the rough milling angle output transfer area 504. The second manipulator structure 300 grabs the semi-finished aluminum floor 700 that has completed the rough milling angle. The second manipulator structure 300 moves and places the semi-finished aluminum floor on the second aluminum floor fixing device 606 of the milling surface equipment 600. On the milling surface equipment 600, the semi-finished aluminum floor is firmly clamped on the top of the second slide rail 605 by the second aluminum floor fixing device 606. The fixed aluminum floor 700 moves along the second slide rail 605 and passes through the upper AC permanent The milling tool 608 driven by the magnetic servo motor 609 completes the milling process of the surface of the aluminum floor 700. The aluminum chips generated by the processing fall directly into the second aluminum chip collection trough 601 located below the milling tool 608. After the milling process is completed, the finished aluminum floor stays at the preset unloading position of the milling equipment 600. The third manipulator structure 400 moves along the transverse guide rail of the gantry bracket 100 and is positioned at the unloading position. The third manipulator structure 400 grabs the finished aluminum floor 700 that has been processed. The third manipulator structure 400 moves and places the finished product on the preset unloading area or conveyor line.

[0067] The automated production line and method for rough angle and surface milling of aluminum floors of the present invention achieve efficient, continuous, and automated production of rough angle and surface milling of aluminum floors through an innovative integrated gantry support layout, three independently coordinated manipulators, an optimized equipment structure design, an efficient source aluminum chip collection system, and a highly flexible fixing and driving method. While significantly improving space utilization, environmental friendliness, operational safety, and equipment adaptability, the advantages include the following:

[0068] 1. Efficient and continuous automated production: The independent and coordinated movement of the first, second, and third manipulator structures 200, 300, and 400 on the crossbeam guide rails of the gantry support 100 enables full automation of the aluminum flooring process, from rough angle milling input, rough angle milling processing, rough angle milling output, to surface milling input, surface milling processing, and unloading. The manipulators have clear divisions of labor: the first manipulator structure 200 loads the rough angle milling, the second manipulator structure 300 transfers to the surface milling, and the third manipulator structure 400 unloads the material. These parallel operations significantly improve production efficiency and continuity.

[0069] Second, a compact and optimized spatial layout: The rough milling device 500, whose movement direction is parallel to the beam, and the surface milling device 600, whose movement direction is perpendicular to the beam, are integrated and arranged below the gantry support 100. The guide rails on the beam of the gantry support 100 support the movement of all manipulators, making full use of the three-dimensional space. This layout greatly reduces the overall equipment footprint;

[0070] 3. Efficient and environmentally friendly collection of aluminum chips at the source: The rough milling device 500 and the surface milling device 600 are each equipped with a dedicated aluminum chip collection trough. The rough milling device 500 is equipped with a first aluminum chip collection trough 501, and the surface milling device 600 is equipped with a second aluminum chip collection trough 601. These troughs are located directly below the processing area to capture aluminum chips at the source. Both collection troughs are equipped with dust suction ports and are connected to negative pressure dust collection devices via pipes, forming a centralized and efficient dust removal system. This effectively improves the working environment, reduces dust pollution, protects worker health, and facilitates the centralized recycling and processing of aluminum chips.

[0071] 4. Optimized design of rough milling equipment to improve efficiency and isolation: The work platform is clearly divided into the rough milling angle input waiting area 503, the rough milling angle output transfer area 504, and the rough milling angle processing area 505. The rough milling angle processing area 505 is elevated, allowing the rough milling angle input waiting area 503, the rough milling angle output transfer area 504 and the rough milling angle processing area 505 to be separated in height, making it easier for the robot to operate in the non-processing area and reducing interference with the processing process; it also provides a more direct and effective space for collecting aluminum chips below the rough milling angle processing area 505, allowing aluminum chips to fall more easily into the collection trough;

[0072] 5. Equipment Versatility and Flexibility: The aluminum floor fixtures on the rough angle milling equipment 500 and the surface milling equipment 600 both use a structure with an adjustable side pressure cylinder. This allows the equipment to adapt to the processing requirements of aluminum flooring 700 of different sizes and specifications, improving the versatility and flexibility of the production line.

[0073] 6. High-precision and reliable milling: The milling cutter 608 is driven by an AC permanent magnet servo motor, providing precise speed control and stable power output, which helps to ensure the quality and accuracy of milling.

[0074] 7. High flexibility and precise positioning of the manipulator: All manipulators are equipped with X, Y, and Z three-axis drive capabilities. The X-axis moves along the beam, covering the length direction of the equipment; the Y-axis moves perpendicular to the beam, covering the width direction of the equipment; the Z-axis rises and falls to achieve material loading and unloading. This structure provides great movement flexibility and spatial coverage capabilities, ensuring that the manipulator can accurately locate at each station of the equipment for loading and unloading operations.

[0075] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
