Description

Technical Field

[0001] This invention generally relates to the field of laser beam processing equipment, and more specifically to a laser cutting and drilling device for curtain wall production. Background Technology

[0002] In curtain wall construction projects, aluminum frames, as the core components constituting the curtain wall skeleton, are typically characterized by their large length (single frames can reach several meters or even more than ten meters), thin wall thickness, and diverse cross-sectional forms. To meet the processing requirements of cutting and drilling aluminum frames for curtain walls, various long strip processing equipment has emerged in existing technologies. These devices generally include a support body extending along the length direction and a processing center that can slide along the support body, with multiple support points arranged above the support body to support the aluminum frame. However, although the support points in existing equipment can theoretically be adjusted and fixed in position on the support body, the actual adjustment method generally relies on the operator manually pushing the support frame to the approximate position and then rigidly locking it with mechanical fasteners such as bolts, set screws, or pins. This combination of manual adjustment and mechanical fixing is not only time-consuming for changing the type of adjustment and difficult to guarantee positioning accuracy, but more importantly, once locked, the spatial position of the support point is completely fixed, making it impossible to adaptively adjust according to the length, cross-sectional characteristics, or real-time processing status of the processed profile.

[0003] The aforementioned artificial fixed support structure has significant technical defects in actual production. On the one hand, for aluminum frame profiles with different lengths, wall thicknesses, or cross-sectional moments of inertia, the reasonable support span required to resist bending deformation varies significantly. On the other hand, the artificially preset spacing of existing support points is often determined solely by experience, lacking scientific quantitative basis. This leads to uncontrollable bending deformation of long, thin-walled aluminum frames under processing loads, which in turn seriously affects the perpendicularity of the cut end face and the accuracy of the drilling position. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a laser cutting and drilling device for curtain wall production, comprising: a support body, the support body being elongated; a machining center disposed above the support body and slidably connected to the support body along its length; and a plurality of support clamping mechanisms arranged at intervals along the length of the support body, each of the support clamping mechanisms including a main frame, the main frame being actively slidable with the support body along its length; wherein, the two support clamping mechanisms located at both ends of the length of the support body are a head support clamping mechanism and a tail support clamping mechanism, respectively, and the head support clamping mechanism and the tail support clamping mechanism are located at the ends of the support body. The tail support clamping mechanism is a middle support clamping mechanism in the middle of the support body; an industrial camera is respectively installed on the head support clamping mechanism and the tail support clamping mechanism to acquire end face images of the strip workpiece; a controller is communicatively connected to the industrial camera and the drive unit of each main frame; the controller is configured to: calculate the length of the strip workpiece based on the end face images acquired by the industrial camera on the head support clamping mechanism and the tail support clamping mechanism, combined with the sliding position information of the head support clamping mechanism and the tail support clamping mechanism, and control each middle support clamping mechanism to slide along the length direction of the support body to the target position.

[0005] With the aforementioned technical features, this equipment can automatically calculate and configure the optimal support span for aluminum frame profiles of different lengths, avoiding the drawbacks of poor positioning accuracy and long adjustment time when manually moving the support frame and rigidly locking it with bolts. At the same time, by accurately matching the distribution of the central support clamping mechanism with the actual length of the workpiece, it provides a scientific quantitative support basis for aluminum frames with different wall thicknesses and cross-sectional moments of inertia, significantly improving the support stability and local bending stiffness of long, thin-walled aluminum frames during laser cutting and drilling, effectively suppressing uncontrollable bending deformation under processing loads, thereby ensuring the perpendicularity of the cutting end face and the accuracy of the drilling position, and greatly improving the automation level and production efficiency of curtain wall aluminum frame processing.

[0006] In some embodiments, the machining center is equipped with a position feedback unit, which is communicatively connected to the controller. The controller is further configured to control the sliding of each of the central support clamping mechanisms according to the real-time position coordinates of the machining center, such that at least some of the central support clamping mechanisms are distributed on the left side of the machining center and at least some of the central support clamping mechanisms are distributed on the right side of the machining center. Thus, this device overcomes the limitations of existing technologies where the support points are completely fixed once locked and cannot be adaptively adjusted according to the real-time machining status. When the machining center moves along the long aluminum frame and performs cutting or drilling operations on different parts, the central support clamping mechanisms can dynamically slide and distribute themselves according to the real-time changes in the machining position, ensuring that the area around the machining point always receives sufficient local stiffness support. This effectively suppresses the local deflection deformation of the long, thin-walled aluminum frame under machining loads, significantly improves the perpendicularity of the cutting end face and the accuracy of the drilling position, and simultaneously achieves effective coordination between support stability and dynamic adaptability in machining.

[0007] In some embodiments, the central support clamping mechanism includes two synchronous support clamping mechanisms and several auxiliary support clamping mechanisms; the two synchronous support clamping mechanisms are respectively located on both sides of the machining center along the length direction and move synchronously with the machining center, and the distance between the two synchronous support clamping mechanisms and the machining center in the length direction is equal; the auxiliary support clamping mechanisms are distributed between one of the synchronous support clamping mechanisms and the head support clamping mechanism, and between the other synchronous support clamping mechanism and the tail support clamping mechanism.

[0008] Therefore, during the movement of the machining center, the equipment can form dense local support on both sides of the machining point that always follows it. At the same time, the auxiliary support clamping mechanism between the head and tail support clamping mechanism and the synchronous support clamping mechanism maintains stable support within the interval, realizing the synergistic optimization of local stiffness of the machining area and overall support stability of the workpiece. Compared with the existing technology where the support points are completely fixed or only single-point following, this layered architecture effectively solves the problem of insufficient local support caused by the dynamic changes in the machining position of long thin-walled aluminum frames during laser cutting and drilling. It significantly suppresses the deflection deformation near the machining point, ensures the perpendicularity of the cutting end face and the accuracy of the drilling position, and improves the equipment's adaptability and automation level for aluminum frame profiles of different lengths and machining paths.

[0009] In some embodiments, each main frame is provided with a drive unit for driving the main frame to slide along the support body. The drive unit includes: a rack, which is fixed inside the support body and extends along the length direction of the support body; a drive motor, which is fixed on the main frame; and a drive gear, which is coaxially fixed on the output shaft of the drive motor and extends from the main frame into the support body to mesh with the rack.

[0010] Thus, this equipment breaks through the limitations of existing technologies where support points rely on manual movement followed by rigid bolt locking. It enables each support and clamping mechanism to automatically, quickly, and accurately adjust its position under the unified scheduling of the controller, based on the workpiece length measurement results or the real-time position of the machining center. The rack and pinion meshing transmission method ensures the positioning accuracy and load stability during the sliding process. The integrated structure of the drive motor and the main frame allows each support and clamping mechanism to form an independent motion unit. This facilitates the controller to drive the head and tail support and clamping mechanisms to perform visual length measurement and positioning, and to drive the middle support and clamping mechanism to perform adaptive distribution and reorganization. This significantly improves the automation level, response speed, and positioning reliability of the support system adjustment, laying a structural foundation for the intelligent support and high-precision machining of long, thin-walled aluminum frames.

[0011] In some embodiments, the support clamping mechanism further includes a clamping assembly disposed on the main frame. The clamping assembly includes a fixed clamping ear fixedly disposed on the upper surface of the main frame; a movable clamping ear slidably connected to the upper surface of the main frame along the length direction of the main frame and arranged opposite to the fixed clamping ear; and a driving member disposed within the main frame for driving the movable clamping ear to move closer to or away from the fixed clamping ear. Thus, by providing a clamping assembly consisting of a fixed clamping ear, a movable clamping ear, and a driving member on the main frame, this aluminum frame cutting and drilling equipment enables each support clamping mechanism to have active clamping capability while supporting strip-shaped workpieces. The fixed clamping ear and the movable clamping ear are arranged opposite to each other along the length direction of the main frame, and the driving member drives the movable clamping ear to move closer to or away from the fixed clamping ear, thereby enabling adaptive adjustment of the clamping spacing according to the workpiece cross-sectional width and reliable clamping of the workpiece.

[0012] In some embodiments, multiple support rollers are spaced apart along the length of the upper surface of the main frame. Each support roller is rotatably connected to the main frame around its central axis, supporting the strip-shaped workpiece and allowing it to slide along the length of the support body. This device solves the problems of rigid contact between the support point and the workpiece in the prior art, resulting in high frictional resistance, surface scratches, or positioning misalignment when the workpiece moves along its length. The rotatable connection structure of the support rollers allows the workpiece to slide smoothly along its length while being supported, avoiding damage to the thin-walled aluminum frame surface caused by rigid dragging, and providing low-resistance conditions for the subsequent downward pressure drive mechanism to move the workpiece. Simultaneously, the spaced arrangement of multiple support rollers ensures continuous and stable rolling support for the long strip-shaped workpiece along its length, effectively dispersing the local stress generated by the workpiece's own weight and reducing workpiece sagging deformation caused by excessive support gaps, thereby improving the stability of workpiece transport and the reliability of processing positioning.

[0013] In some embodiments, auxiliary rollers are embedded on the opposite sides of the fixed clamping ear and the movable clamping ear, and each auxiliary roller is rotatably connected to the corresponding clamping ear around its own central axis, for rolling contact with the side surface of the strip workpiece in the clamping state. Thus, this device solves the problems of rigid surface contact between the clamping mechanism and the workpiece side surface in the prior art, high frictional resistance when the workpiece moves along its length, and easy generation of clamping marks or scratches on the workpiece surface; the rolling contact structure of the auxiliary rollers allows the workpiece to slide smoothly along the length of the supporting body while remaining clamped and fixed, achieving an organic unity of the two functions of "clamping and positioning" and "longitudinal conveying"; at the same time, the auxiliary rollers, the support rollers on the upper surface of the main frame, and the active rollers of the machining center's downward driving mechanism form a rolling cooperation system in all directions, ensuring that the long strip aluminum frame is in a low-friction rolling state throughout the entire process of support, clamping, pressing, and conveying, significantly reducing the risk of workpiece surface damage, improving the stability of workpiece movement and the reliability of processing positioning, and providing a stable clamping and conveying guarantee for the high-precision automated processing of curtain wall aluminum frames.

[0014] In some embodiments, the machining center integrates a pressing drive mechanism, which includes a pressing arm and an active roller rotatably connected to the end of the pressing arm about its own central axis. The active roller integrates a rotary drive component. The active roller is used to contact the upper surface of the strip workpiece when the pressing arm presses down, and to drive the strip workpiece to move along the length direction of the support body.

[0015] Therefore, this equipment solves the problems of existing machining centers that only have machining functions and rely on independent feeding devices or manual assistance for workpiece conveying, resulting in a dispersed equipment structure and low process connection efficiency. By integrating the pressing and fixing function with the active conveying function into the machining center, the machining center can directly drive the workpiece to move accurately along its length while pressing and fixing it, realizing the integrated coordination of pressing and positioning and active feeding. At the same time, the active roller, the support rollers on the upper surface of the main frame, and the auxiliary rollers on the clamping lugs form a rolling conveying system that allows the workpiece to be in a low-friction rolling state throughout the entire process of supporting, clamping, pressing, and conveying. This significantly reduces the risk of workpiece surface damage, improves the stability of workpiece movement and the accuracy of feeding and positioning, and provides a compact and efficient mechanism to ensure the continuous, automated, and high-precision processing of curtain wall aluminum frames.

[0016] In some embodiments, the controller determines the target position of each of the auxiliary support clamping mechanisms according to the following steps: obtaining the position coordinates of the head support clamping mechanism and the tail support clamping mechanism, and calculating the distance between them; calculating the visual compensation amount based on the pixel offset of the two ends of the strip workpiece relative to the corresponding main frame reference position as identified by the industrial camera; superimposing the distance and the visual compensation amount to obtain the actual length of the strip workpiece; and calculating the distribution position of each of the auxiliary support clamping mechanisms based on the actual length and a preset support span threshold.

[0017] Therefore, by combining the coarse baseline provided by the sliding position of the support frame with the visual fine compensation provided by the end face recognition of the industrial camera, the length measurement accuracy of long strip workpieces is significantly improved, providing a reliable data foundation for subsequent support layout. At the same time, based on the quantitative calculation of the actual length and the support span threshold, the number and distribution of auxiliary support clamping mechanisms can be scientifically and adaptively configured for aluminum frame profiles of different lengths and wall thicknesses. This avoids workpiece deflection caused by too few supports or clamping interference caused by too many supports. Thus, while ensuring the processing stability of long thin-walled aluminum frames, the optimal utilization of support resources is achieved, improving the processing adaptability and automation level of the equipment.

[0018] In some embodiments, the controller is configured to: acquire the position coordinates of the machining center in real time during the sliding process of the machining center along the length direction of the support body, and control each of the synchronous support clamping mechanisms to move synchronously with the machining center; calculate a first distance between the head support clamping mechanism and the adjacent synchronous support clamping mechanism, and a second distance between the tail support clamping mechanism and the adjacent synchronous support clamping mechanism, based on the real-time positions of the head support clamping mechanism, the tail support clamping mechanism, and each of the synchronous support clamping mechanisms; calculate the target distribution position of each of the auxiliary support clamping mechanisms within the first distance and the second distance, based on the first distance, the second distance, and the number of each of the auxiliary support clamping mechanisms, and drive each of the auxiliary support clamping mechanisms to slide to the corresponding target distribution position, so that each of the auxiliary support clamping mechanisms remains uniformly distributed within the first distance and the second distance.

[0019] Therefore, by constructing a layered collaborative support architecture in which "synchronous support closely follows the machining center and auxiliary support is evenly distributed within the dynamic range", a local dense support effect is always formed around the machining area, while the interval between the head and tail and the synchronous support maintains global stiffness balance through the dynamic and even distribution of auxiliary support. When the machining center moves along the long aluminum frame and performs cutting or drilling operations on different parts, the entire support system can actively optimize and reorganize according to the real-time changes in the machining position, ensuring that the optimal support topology layout is obtained at any machining moment. This significantly suppresses the local deflection deformation of the long thin-walled aluminum frame under the action of machining load, effectively ensures the perpendicularity of the cutting end face and the accuracy of the drilling position, and greatly improves the dynamic adaptability and automation level of the curtain wall aluminum frame processing process.

[0023] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] The following is for reference. Figures 1-4 This invention describes a laser cutting and drilling device for curtain wall production.

[0025] Figure 1 A schematic diagram of the overall structure of a laser cutting and drilling device for curtain wall production, according to an embodiment of the present invention, is shown. (Reference) Figure 1 As shown, a laser cutting and drilling device for curtain wall production includes a support body 1, a machining center 2, multiple support clamping mechanisms, an industrial camera 32, and a controller. The support body 1 is elongated, and the machining center 2 is positioned above the support body 1 and slidably connected to it along its length. Multiple support clamping mechanisms are spaced apart along the length of the support body 1, each including a main frame 31 that actively slides along its length. Two support clamping mechanisms at either end of the support body 1 are a head support clamping mechanism 34 and a tail support clamping mechanism 35, respectively. A middle support clamping mechanism 36 is located between the head and tail support clamping mechanisms 34 and 35, respectively. The industrial camera 32 is mounted on the head and tail support clamping mechanisms 34 and 35, respectively, to acquire end-face images of the elongated workpiece. The controller is communicatively connected to the industrial camera 32 and the drive unit 4 of each main frame 31. The controller is configured to calculate the length of the strip workpiece based on the end face images obtained by the industrial camera 32 on the head support clamping mechanism 34 and the tail support clamping mechanism 35, combined with the sliding position information of the head support clamping mechanism 34 and the tail support clamping mechanism 35, and control each middle support clamping mechanism 36 to slide along the length direction of the support body 1 to the target position.

[0026] The support body 1 is the basic load-bearing structure of the equipment, extending along its length to support the machining center 2 and various support and clamping mechanisms. The machining center 2 is a processing unit that performs cutting and drilling operations. It can move along the width of the support body 1 to adjust the drilling and cutting area, and it can also move along its length to adapt to different processing positions. The support and clamping mechanisms are support and clamping units for strip-shaped workpieces, arranged at intervals along the support body 1 to support the workpieces. The main frame 31 is the base structure of the support and clamping mechanisms, forming an active sliding fit with the support body 1, and can move independently along the length of the support body 1. The head support and clamping mechanism 34 is the support and clamping mechanism located at one end of the support body 1, and the tail support and clamping mechanism 35 is the support and clamping mechanism located at the other end of the support body 1. The two structures work together to support both ends of the workpiece; the middle support clamping mechanism 36 is a support clamping mechanism located between the head support clamping mechanism 34 and the tail support clamping mechanism 35, used to support the middle of the workpiece; the industrial camera 32 is an image acquisition device, installed on the head support clamping mechanism 34 and the tail support clamping mechanism 35, facing the end face of the workpiece to obtain the end face image; the controller is the control unit of the equipment, forming a communication connection with the industrial camera 32 and the drive units 4 of each main frame 31, used to receive image data and position data and output control commands; the sliding position information is the real-time position data of the main frame 31 in the length direction of the support body 1; the target position is the support position that the middle support clamping mechanism 36 should move to after calculating the length of the workpiece.

[0027] During operation, the industrial cameras 32 on the head support clamping mechanism 34 and the tail support clamping mechanism 35 acquire end face images of both ends of the strip-shaped workpiece. The controller, combining the sliding position information of the end support clamping mechanisms, calculates the real-time length of the strip-shaped workpiece and accordingly controls each middle support clamping mechanism 36 to actively slide to a target position adapted to the workpiece length. This allows multiple support clamping mechanisms to be evenly distributed or arranged as needed along the workpiece length, providing adaptive support for strip-shaped workpieces of different lengths. The machining center 2 slides along the support body 1 to the corresponding position to perform cutting and drilling operations. This structure allows the position of the support clamping mechanisms to be automatically adjusted according to the actual length of the workpiece, avoiding the tedious operation of manual measurement and adjustment of the support position, and improving the equipment's adaptability to workpieces of different specifications and processing efficiency.

[0028] In some embodiments, the machining center 2 is equipped with a position feedback unit, which is communicatively connected to the controller; the controller is also configured to control the sliding of each central support clamping mechanism 36 according to the real-time position coordinates of the machining center 2, such that at least some of the central support clamping mechanisms 36 are distributed on the left side of the machining center 2 and at least some of the central support clamping mechanisms 36 are distributed on the right side of the machining center 2.

[0029] The position feedback unit is a position detection device installed on the machining center 2, used to collect the position coordinates of the machining center 2 in the length direction of the support body 1 in real time, and transmit the coordinate data to the controller. The controller is the control unit of the equipment, which is communicatively connected to the position feedback unit and the drive units 4 of each main frame 31, and is used to receive the position data of the machining center 2 and output the sliding control command of the support clamping mechanism. The real-time position coordinates are the specific position values ​​of the machining center 2 in the length direction of the support body 1. The left and right sides are two areas divided along the length direction of the support body 1 with the machining center 2 as a reference. The position feedback unit and the industrial camera 32 share the same controller, so that the position information of the machining center 2 and the workpiece length information are processed collaboratively under the same control logic.

[0030] This structure allows the distribution of the central support clamping mechanism 36 to be dynamically adjusted according to the real-time position of the machining center 2. During the movement of the machining center 2, the controller redistributes the central support clamping mechanism 36 according to the real-time position coordinates of the machining center 2, so that there are always enough support points on both sides of the machining center 2. This avoids the workpiece from drooping or deforming due to insufficient support on that side when the machining center 2 moves to a certain area, thereby ensuring the support stability of the strip workpiece during the processing and improving the processing quality of cutting and drilling.

[0031] In some embodiments, Figure 2 This diagram illustrates the distribution structure of multiple support and clamping mechanisms in a laser cutting and drilling device for curtain wall production, according to an embodiment of the present invention. (See reference) Figure 2 As shown, the middle support clamping mechanism 36 includes two synchronous support clamping mechanisms 361 and several auxiliary support clamping mechanisms 362; the two synchronous support clamping mechanisms 361 are located on both sides of the machining center 2 along the length direction and move synchronously with the machining center 2, and the distance between the two synchronous support clamping mechanisms 361 and the machining center 2 in the length direction is equal; the auxiliary support clamping mechanisms 362 are distributed between one of the synchronous support clamping mechanisms 361 and the head support clamping mechanism 34, and between the other synchronous support clamping mechanism 361 and the tail support clamping mechanism 35.

[0032] The central support clamping mechanism 36 is the general term for the support clamping units in the central region of the support body 1, including two types: synchronous support clamping mechanism 361 and auxiliary support clamping mechanism 362. Synchronous support clamping mechanism 361 is a support clamping mechanism that moves in conjunction with machining center 2, and is arranged on both sides of machining center 2 along the length of support body 1, maintaining a fixed distance from machining center 2 and moving synchronously with it. Auxiliary support clamping mechanism 362 is a fixedly arranged or independently controlled support clamping mechanism, distributed between synchronous support clamping mechanism 361 and head support clamping mechanism 34, and between synchronous support clamping mechanism 361 and tail support clamping mechanism 35, used to fill the support gap area between synchronous support clamping mechanism 361 and the two end support clamping mechanisms. Equal spacing means that the two synchronous support clamping mechanisms 361 are equidistant from machining center 2 in the length direction, forming a symmetrical support layout on both sides of machining center 2. Synchronous support clamping mechanism 361 and machining center 2 are coordinated and controlled by the same controller, ensuring that the displacement of the three remains linked.

[0033] This structure ensures that during the movement of machining center 2, it is always supported symmetrically by synchronous support clamping mechanisms 361 on both sides, preventing workpiece deflection and deformation caused by excessively far support points in the vicinity of machining center 2. At the same time, auxiliary support clamping mechanism 362 forms a transition support between synchronous support clamping mechanism 361 and end support clamping mechanisms, so that the entire workpiece has continuously distributed support points along its length, reducing vibration and deformation caused by excessive span, thereby improving the overall support rigidity and processing stability of long strip workpieces during cutting and drilling.

[0034] In some embodiments, the controller determines the target position of each auxiliary support clamping mechanism 362 according to the following steps: obtaining the position coordinates of the head support clamping mechanism 34 and the tail support clamping mechanism 35, and calculating the distance between them; calculating the visual compensation amount based on the pixel offset of the two ends of the strip workpiece relative to the reference position of the corresponding main frame 31 as identified by the industrial camera 32; superimposing the distance and the visual compensation amount to obtain the actual length of the strip workpiece; and calculating the distribution position of each auxiliary support clamping mechanism 362 based on the actual length and the preset support span threshold.

[0035] The position coordinates are the real-time position values ​​of the main frame 31 of the head support clamping mechanism 34 and the tail support clamping mechanism 35 along the length of the support body 1, obtained by position feedback from the main frame 31 drive unit 4 or by encoder acquisition; the spacing is the difference between the position coordinates of the head support clamping mechanism 34 and the tail support clamping mechanism 35, representing the physical distance between the two end support clamping mechanisms; the pixel offset is the pixel distance difference between the edge of the strip workpiece end face and the reference position of the main frame 31 in the image coordinate system in the end face image acquired by the industrial camera 32, which is identified by the controller through image processing algorithm; the visual compensation is the actual length correction value calculated based on the pixel offset and camera calibration parameters, used to compensate for the position deviation between the workpiece end face and the clamping reference surface of the main frame 31; the actual length is the true length of the workpiece after the spacing and the visual compensation are superimposed; the support span threshold is the preset maximum allowable distance between adjacent support clamping mechanisms, used to determine the number and distribution density of auxiliary support clamping mechanisms 362; the distribution position is the target coordinate to which each auxiliary support clamping mechanism 362 should move along the length of the support body 1. The controller, industrial camera 32, main frame 31 and drive unit 4 form a closed-loop control, so that visual recognition data and mechanical position data are fused and processed in the same computing logic.

[0036] This control method integrates mechanical position information and visual recognition information in the calculation of workpiece length. It calculates visual compensation through pixel offset, correcting the length measurement error caused by the misalignment of the workpiece end face with the clamping reference surface of the main frame 31, thus improving the accuracy of the actual workpiece length calculation. At the same time, it automatically plans the distribution position of the auxiliary support clamping mechanism 362 according to the actual length and the support span threshold, so that the number and spacing of the support points are adapted to the workpiece length. This avoids the problem of too few support points leading to an excessive span or too many support points leading to mechanism redundancy, thereby improving the rationality of the support layout and the stability of the processing.

[0037] In some embodiments, the controller is configured to acquire the position coordinates of the machining center 2 in real time during the sliding process of the machining center 2 along the length direction of the support body 1, and control each synchronous support clamping mechanism 361 to move synchronously with the machining center 2; calculate the first distance between the head support clamping mechanism 34 and the adjacent synchronous support clamping mechanism 361, and the second distance between the tail support clamping mechanism 35 and the adjacent synchronous support clamping mechanism 361, based on the real-time positions of the head support clamping mechanism 34, the tail support clamping mechanism 35, and each synchronous support clamping mechanism 361; calculate the target distribution position of each auxiliary support clamping mechanism 362 within the first distance and the second distance, based on the first distance, the second distance, and the number of each auxiliary support clamping mechanism 362, and drive each auxiliary support clamping mechanism 362 to slide to the corresponding target distribution position, so that each auxiliary support clamping mechanism 362 is uniformly distributed within the first distance and the second distance.

[0038] The first spacing is the distance along the length of the support body 1 between the head support clamping mechanism 34 and its adjacent synchronous support clamping mechanism 361; the second spacing is the distance along the length of the support body 1 between the tail support clamping mechanism 35 and its adjacent synchronous support clamping mechanism 361; the target distribution position is the coordinate position to which each auxiliary support clamping mechanism 362 should move, calculated according to the principle of uniform distribution within the first or second spacing; uniform distribution means that each auxiliary support clamping mechanism 362 is arranged at equal intervals within the corresponding spacing. The controller, the position feedback unit of the machining center 2, and the drive units 4 of each main frame 31 form a linkage control, so that the synchronous support clamping mechanism 361 follows the displacement of the machining center 2, and at the same time, the distribution state of the auxiliary support clamping mechanism 362 is dynamically adjusted according to the real-time changes of the first and second spacings.

[0039] This control method ensures that during the movement of machining center 2, the synchronous support clamping mechanism 361 always follows its synchronous displacement, maintaining symmetrical support on both sides of machining center 2. Simultaneously, the controller dynamically calculates and adjusts the distribution position of the auxiliary support clamping mechanism 362 based on the real-time changes in the distance between the head support clamping mechanism 34 and the synchronous support clamping mechanism 361, and between the tail support clamping mechanism 35 and the synchronous support clamping mechanism 361. This ensures that the auxiliary support clamping mechanism 362 remains uniformly distributed within the changing distances, preventing workpiece sagging deformation caused by excessive support span on one side due to the movement of machining center 2. This results in continuous and reasonably spaced support coverage of the entire workpiece along its length, improving the support consistency and processing stability of long, strip-shaped workpieces during the movement of machining center 2.

[0040] In some embodiments, reference Figure 2 As shown, each main frame 31 is provided with a drive unit 4, which is used to drive the main frame 31 to slide along the support body 1. The drive unit 4 includes a rack 41, a drive motor 42 and a drive gear 43. The rack 41 is fixed inside the support body 1 and extends along the length direction of the support body 1. The drive motor 42 is fixed on the main frame 31. The drive gear 43 is coaxially fixed on the output shaft of the drive motor 42 and extends from the main frame 31 into the support body 1 to mesh with the rack 41.

[0041] The drive unit 4 is an active drive device mounted on the main frame 31, used to provide power for the main frame 31 to move along the length of the support body 1. The rack 41 is a linear toothed track arranged along the length of the support body 1, fixed in the internal cavity of the support body 1, and serves as the transmission reference component of the drive unit 4. The drive motor 42 is a rotary power source fixed on the main frame 31, with its output shaft extending towards the interior of the support body 1. The drive gear 43 is a cylindrical gear mounted on the output shaft of the drive motor 42, and its teeth mesh with the tooth grooves of the rack 41. When the drive motor 42 rotates, the drive gear 43 rolls along the rack 41, driving the main frame 31 and the support clamping mechanism as a whole to slide along the length of the support body 1. The meshing relationship between the rack 41 and the drive gear 43 converts the rotary motion into linear motion. The drive motor 42 is communicatively connected to the controller and receives displacement commands from the controller to achieve precise positioning.

[0042] This drive structure equips each main frame 31 of the support and clamping mechanism with an independent drive unit 4. Each main frame 31 can slide independently along the support body 1 without interfering with each other. This allows the controller to control the distribution of each support and clamping mechanism according to the workpiece length and the position of the machining center 2. The rack 41 is fixed inside the support body 1, and the drive gear 43 extends from the main frame 31 into the support body 1 to mesh with it. This structure integrates the transmission components into the support body 1, reducing the externally exposed transmission mechanism and reducing the pollution and wear of the transmission pair by dust and chips. At the same time, it makes the connection structure between the main frame 31 and the support body 1 more compact, improving the overall structural rigidity and operational stability of the equipment.

[0043] Figure 3 A schematic diagram of a support and clamping mechanism in a laser cutting and drilling device for curtain wall production, according to an embodiment of the present invention, is shown. (Reference) Figure 3 As shown, the support clamping mechanism also includes a clamping assembly 33 disposed on the main frame 31. The clamping assembly 33 includes a fixed clamping ear 331, a movable clamping ear 332, and a driving member 333. The fixed clamping ear 331 is fixedly disposed on the upper surface of the main frame 31. The movable clamping ear 332 is slidably connected to the upper surface of the main frame 31 along the length direction of the main frame 31 and is arranged opposite to the fixed clamping ear 331. The driving member 333 is disposed inside the main frame 31 and is used to drive the movable clamping ear 332 to move closer to or away from the fixed clamping ear 331.

[0044] The clamping assembly 33 is a workpiece clamping unit mounted on the main frame 31, used to clamp and fix strip-shaped workpieces. The fixed clamping ear 331 is a clamping block fixed to the upper surface of the main frame 31, serving as the reference clamping surface of the clamping assembly 33. The movable clamping ear 332 is a clamping block that can move along the length direction of the main frame 31, cooperating with the fixed clamping ear 331 to form a clamping space. The driving component 333 is a linear drive device mounted inside the main frame 31, which can be a hydraulic cylinder or a linear drive structure with a lead screw and nut. It is connected to the movable clamping ear 332 to provide linear power for the movable clamping ear 332 to move closer to or away from the fixed clamping ear 331. The length direction of the main frame 31 is perpendicular to the length direction of the supporting body 1, that is, the transverse direction perpendicular to the length direction of the workpiece. The opposing surfaces of the fixed clamping ear 331 and the movable clamping ear 332 form the contact surface for clamping the workpiece. The driving component 333 is communicatively connected to the controller and receives clamping commands to achieve automatic clamping or releasing.

[0045] The clamping assembly 33 brings the movable clamping ear 332 closer to the fixed clamping ear 331 under the action of the driving component 333, forming a clamping force from both sides of the workpiece to fix the strip workpiece on the main frame 31 and prevent the workpiece from shifting or vibrating during processing. The structure of the movable clamping ear 332 sliding along the length of the main frame 31 allows the clamping assembly 33 to adapt to strip workpieces of different widths. By adjusting the distance between the movable clamping ear 332 and the fixed clamping ear 331, various specifications of workpieces can be clamped. At the same time, the clamping assembly 33 is integrated into the main frame 31, making the support and clamping functions integrated, reducing the arrangement space of independent fixtures, and enabling each support and clamping mechanism to provide support while also having a clamping function, thereby improving the integration of the equipment for workpiece fixation and support.

[0046] In some embodiments, a plurality of support rollers 334 are spaced apart along the length of the upper surface of the main frame 31. Each support roller 334 is rotatably connected to the main frame 31 around its own central axis, and is used to support the strip-shaped workpiece and allow the strip-shaped workpiece to slide along the length of the support body 1. The support rollers 334 are cylindrical rotating components mounted on the upper surface of the main frame 31 and are arranged at intervals along the length of the main frame 31. Their own central axis is the rotation center axis of the support rollers 334, extending in a horizontal direction perpendicular to the length of the support body 1. The rotatable connection is a structure in which the support rollers 334 are mounted on the main frame 31 through bearings or shaft holes, and can rotate freely around their own central axis. The length of the main frame 31 is perpendicular to the length of the support body 1, i.e., horizontal. The upper edge of the support rollers 334 protrudes from the upper surface of the main frame 31, forming a contact and support surface with the strip-shaped workpiece. When the strip-shaped workpiece is placed on the support rollers 334, its bottom surface forms a rolling contact with the support rollers 334.

[0047] The support roller 334 changes the sliding contact between the strip workpiece and the main frame 31 to a rolling contact. During workpiece placement or position adjustment, the strip workpiece can slide along the length of the support body 1 on the support roller 334, reducing the frictional resistance during workpiece movement and facilitating workpiece position adjustment between the support and clamping mechanisms. At the same time, the support rollers 334 are spaced apart along the length of the main frame 31, providing multi-point distributed support for the bottom surface of the workpiece and avoiding workpiece deformation caused by single-point support. The rotating connection structure of the support rollers 334 allows the workpiece to slide smoothly when pushed by external force, and static friction is formed between the workpiece and the support rollers 334 after clamping by the clamping assembly 33, keeping the workpiece fixed, thus balancing the convenience of workpiece placement and the stability during processing.

[0048] In some embodiments, an auxiliary roller 335 is embedded on the side of the fixed clamping ear 331 and the movable clamping ear 332 facing each other. Each auxiliary roller 335 is rotatably connected to the corresponding clamping ear around its own central axis and is used to roll in contact with the side surface of the strip workpiece in the clamping state. The auxiliary roller 335 is a cylindrical rotating component installed on the opposite surfaces of the fixed clamping ear 331 and the movable clamping ear 332, and is embedded in the groove or mounting hole of the clamping ear; its own central axis is the rotational central axis of the auxiliary roller 335, arranged in the vertical or inclined direction; the rotatable connection is a structure in which the auxiliary roller 335 is installed on the clamping ear through bearings or shaft hole fit, and can rotate freely around its own central axis; the corresponding clamping ear refers to the auxiliary roller 335 on the fixed clamping ear 331 being installed on the opposite side of the fixed clamping ear 331, and the auxiliary roller 335 on the movable clamping ear 332 being installed on the opposite side of the movable clamping ear 332; the clamping state is that the movable clamping ear 332 approaches the fixed clamping ear 331 under the action of the driving member 333, so that the auxiliary rollers 335 on both sides form contact with the side surface of the strip workpiece; the side surface is the two vertical surfaces of the strip workpiece along the length direction. The rim of the auxiliary roller 335 protrudes from the clamping surface of the clamping lug, so that the auxiliary roller 335 contacts the workpiece before the clamping lug body during clamping.

[0049] The auxiliary roller 335 enables the fixed clamping ear 331 and the movable clamping ear 332 to form rolling contact with the side surface of the strip workpiece through the auxiliary roller 335, rather than rigid surface contact, when the strip workpiece undergoes slight expansion and contraction along its length due to temperature changes or processing stress. The auxiliary roller 335 can rotate around its own central axis, allowing the workpiece to slide controllably along its length under clamping constraints, thus avoiding workpiece deformation or stress concentration caused by rigid clamping. At the same time, the structure of the auxiliary roller 335 embedded in the clamping ear integrates the rolling contact function into the original clamping assembly 33, eliminating the need for an additional guide mechanism. This simplifies the structure of the supporting clamping mechanism, allowing the workpiece to retain a certain degree of longitudinal freedom while obtaining reliable clamping, and improving the equipment's adaptability to the thermal expansion and contraction deformation of long strip workpieces.

[0050] Figure 4 This diagram illustrates a side view of machining center 2 in a laser cutting and drilling device for curtain wall production, according to an embodiment of the present invention. (See reference) Figure 4 As shown, the machining center 2 is equipped with a pressing drive mechanism 5. The pressing drive mechanism 5 includes a pressing arm 51 and an active roller 52 that is rotatably connected to the end of the pressing arm 51 around its own central axis. The active roller 52 is equipped with a rotary drive component. The active roller 52 is used to contact the upper surface of the strip workpiece when the pressing arm 51 presses down, and drive the strip workpiece to move along the length direction of the support body 1.

[0051] The downward pressure drive mechanism 5 is an auxiliary drive device installed on the machining center 2, used to apply downward pressure to the strip-shaped workpiece and provide longitudinal driving force during processing; the downward pressure arm 51 is the swing or lifting actuator arm of the downward pressure drive mechanism 5, one end of which is connected to the extension arm on one side of the machining center 2, and the other end extends upward toward the strip-shaped workpiece; the drive roller 52 is a cylindrical rotating component installed at the end of the downward pressure arm 51, and its rotation axis is arranged in a horizontal direction perpendicular to the length direction of the support body 1; its own central axis is the rotation center axis of the drive roller 52; the rotary drive component is a motor or rotary actuator integrated inside the drive roller 52, used to drive the drive roller 52 to rotate around its own central axis; the upper surface is the top surface of the strip-shaped workpiece facing the machining center 2. The downward pressure arm 51 is connected to the lifting drive mechanism of the machining center 2 and can move closer to or away from the strip-shaped workpiece in a vertical direction; the drive roller 52 is rotatably connected to the end of the downward pressure arm 51 through a bearing, and the output end of the rotary drive component is connected to the roller body of the drive roller 52.

[0052] The downward driving mechanism 5 enables the machining center 2 to press down the active roller 52 until it contacts the upper surface of the strip workpiece during the machining process. The rotating drive component inside the active roller 52 drives the active roller 52 to rotate, and the friction between the active roller 52 and the upper surface of the workpiece drives the strip workpiece to move along the length direction of the support body 1. This structure enables the longitudinal feed of the workpiece to be realized by the downward driving mechanism 5 of the machining center 2 itself, without the need for an additional feeding device or manual pushing, which simplifies the overall layout of the equipment. At the same time, the downward action of the active roller 52 keeps the workpiece in contact with the support roller 334 during the movement, reducing the jumping or deviation of the workpiece during the feeding process, thereby improving the stability of the workpiece feeding and the consistency of the machining process.
