Description

Technical Field

[0001] This invention relates to the field of laser drilling, and more specifically, to an automatic laser drilling machine and method for curtain walls. Background Technology

[0002] With the rapid development of modern building curtain wall engineering, the application of aluminum alloy curtain wall frames is becoming increasingly widespread. During the curtain wall installation process, precise holes need to be drilled in the aluminum alloy curtain wall frame for connecting fasteners, decorative elements, or pipelines.

[0003] Existing laser drilling machines retract the laser head directly from the workpiece after drilling, performing only simple air cleaning during the retraction process. This fails to effectively remove burrs from the hole edges. Due to the high temperature during laser cutting, molten material inevitably accumulates and burrs form at the hole edges. These burrs affect subsequent assembly accuracy and aesthetics, and in severe cases, can even injure construction workers. Therefore, we propose an automatic laser drilling machine and method for curtain walls. Summary of the Invention

[0004] This invention provides an automatic laser drilling machine and method for curtain walls, which solves the technical problem in related technologies where the laser head is directly withdrawn from the workpiece, and only simple air blowing is performed during the withdrawal process, which cannot effectively treat the burrs on the edge of the hole.

[0005] The first aspect of the present invention provides an automatic laser drilling machine for curtain walls, comprising: a laser drilling host, wherein a composite burr removal module is integrated on the laser head, and the composite burr removal module is configured to simultaneously spray diamond abrasive to deburr the newly formed hole during the retraction process of the laser head away from the aluminum alloy curtain wall frame after laser drilling is completed.

[0006] The composite burr removal module includes: an outer casing, which is fitted onto the end of the laser head 5-8cm using a ring-shaped sleeve structure;

[0007] The sandblasting head assembly consists of multiple sandblasting heads that can be adjusted simultaneously, arranged in a ring array inside the outer casing. The sandblasting direction of each sandblasting head is the same as the axis of the laser head.

[0008] The sand supply module is connected to each sandblasting head;

[0009] The adjustment module is connected to each sandblasting head;

[0010] The industrial inspection module integrates a laser scanner and an image processor for real-time acquisition of the geometric parameters of the holes;

[0011] The adjustment module is configured to: based on the hole diameter, position and shape data detected by the industrial detection module, control the sandblasting point of the sandblasting head array to be precisely adjusted to start sandblasting 2-3mm outside the hole, and dynamically shrink the sandblasting range during the sandblasting process to form a gradually shrinking sandblasting path.

[0012] Furthermore, a limiting ring is rotatably installed inside the outer casing, with a series of limiting grooves on the limiting ring, and a protective ball cover is fixedly installed on the limiting groove to fully cover the limiting groove.

[0013] Furthermore, the sandblasting head includes a nozzle, a reaction rope, and a support plate. The nozzle and the support plate are integrated into one piece. The support plate is rotatably mounted in a limiting groove, and the diameter of the limiting groove is larger than the diameter of the support plate. The reaction rope is mounted on the outer wall of the nozzle and always pulls the nozzle away from the center of the limiting ring. The end of the reaction rope away from the nozzle is fixed to the lower wall of the limiting ring.

[0014] Furthermore, the outer wall of the limiting ring is provided with a rotating bead and a spring. The limiting ring is rotatably connected to the outer cover box through the rotating bead, and the rotation range of the limiting ring is limited by the spring. The rotation range of the limiting ring is 0-2cm.

[0015] Furthermore, the sand supply module includes a sand supply pipe and a sand passage ring pipe. The end of the sand supply pipe away from the outer cover is connected to the sand blasting module. The sand passage ring pipe is connected to the sand supply pipe and is located above the protective sphere. It passes through the protective sphere and is connected to all the sand blasting heads. The sand blasting module is fixed to the side wall of the laser drilling host.

[0016] Furthermore, the composite burr removal module also includes an air supply pipe and an air circulation ring pipe. The end of the air supply pipe away from the outer casing is connected to the air supply module, which is fixed to the side wall of the laser drilling host.

[0017] Furthermore, a ventilation ring pipe is also installed above the protective sphere. The ventilation ring pipe is connected to the air supply pipe and passes through the protective sphere via a flexible hose, for spraying air downwards from the gap in the limiting groove.

[0018] Furthermore, the adjustment module includes an electrical box, inside which are fixedly installed an adjustment push rod and an angle adjustment push rod. An adjustment screw is connected to the telescopic column of the adjustment push rod, and the end of the adjustment screw away from the adjustment push rod is connected to a limit ring. By dynamically changing the telescopic column of the adjustment push rod, the limit ring is pulled to rotate.

[0019] Furthermore, an angle-adjusting wire is connected to the telescopic column of the angle-adjusting push rod. The end of the angle-adjusting wire away from the angle-adjusting push rod is connected to a ring-shaped series rope. Tension wires are arrayed on the series rope. Each tension wire corresponds to a protective ball cover, and all tension wires pass through the corresponding protective ball cover. They are then fixedly connected to the sandblasting head column. The angle adjustment push rod extends to pull all the sandblasting heads to retract at different angles.

[0020] A second aspect of the present invention provides a method for an automatic laser drilling machine for curtain walls, comprising the following steps:

[0021] S1. The laser drilling host completes laser drilling at the predetermined position on the curtain wall frame;

[0022] S2, the industrial detection module collects and calculates the geometric parameters of the holes in real time;

[0023] S3. Based on geometric parameters, the adjustment module controls the sandblasting head group of the composite burr removal module so that its sandblasting point is aligned with the predetermined position outside the hole.

[0024] S4. During the laser head retraction process, the composite burr removal module starts sandblasting, and at the same time, the adjustment module dynamically shrinks and closes the sandblasting range according to the preset path to perform gradual sandblasting treatment on the holes.

[0025] S5. The blade retraction is complete, sandblasting stops, and the burrs in the holes are removed.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention integrates a composite burr removal module into the laser head, enabling simultaneous laser drilling and burr removal. As the laser head completes drilling and retracts, the composite burr removal module simultaneously initiates sandblasting to remove burrs from the newly formed hole, eliminating the need for additional processing steps and greatly improving processing efficiency.

[0028] By setting an adjustment module, based on the hole data detected by the industrial detection module, the sandblasting point of the sandblasting head array is precisely adjusted to start sandblasting 2-3mm outside the hole. During the sandblasting process, the sandblasting range is dynamically reduced to form a gradually narrowing sandblasting path. This gradually narrowing sandblasting path can ensure that the burr treatment gradually narrows from the outside of the hole to the edge of the hole, achieving a uniform and consistent burr treatment effect and avoiding the problems of over-treatment or under-treatment.

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0039] Example 1

[0040] like Figures 1-8 As shown, an automatic laser drilling machine for curtain walls includes: a laser drilling host 11, on which a composite burr removal module 2 is integrated. The composite burr removal module 2 is configured to spray diamond abrasive to deburr the newly formed hole during the retraction process of the laser head away from the aluminum alloy curtain wall frame after laser drilling is completed.

[0041] The composite burr removal module 2 includes: an outer cover 21, which is fitted onto the end of the laser head 5-8cm using a ring-shaped sleeve structure;

[0042] The sandblasting head 27 group consists of multiple sandblasting heads 27 that can be adjusted simultaneously, arranged in a ring array inside the outer cover box 21, and the sandblasting direction of each sandblasting head 27 is the same as the axis of the laser head.

[0043] The sand supply module is connected to each sandblasting head 27;

[0044] The adjustment module is connected to each sandblasting head 27;

[0045] The industrial inspection module 51 integrates a laser scanner and an image processor for real-time acquisition of the geometric parameters of the holes;

[0046] The adjustment module is configured to: based on the hole diameter, position and shape data detected by the industrial detection module 51, control the sandblasting point of the sandblasting head array 27 to be precisely adjusted to start sandblasting 2-3mm outside the hole, and dynamically shrink the sandblasting range during the sandblasting process to form a gradually shrinking sandblasting path.

[0047] Inside the outer cover box 21, a limiting ring 28 is rotatably installed. The limiting ring 28 has an array of limiting grooves 34. A protective ball cover 31 is fixedly installed on the limiting grooves 34 to fully cover them.

[0048] The sandblasting head 27 includes a nozzle 271, a reaction rope 272, and a support plate 273. The nozzle 271 and the support plate 273 are integrally formed. The support plate 273 is rotatably mounted in the limiting groove 34, and the diameter of the limiting groove 34 is larger than the diameter of the support plate 273. The reaction rope 272 is located on the outer wall of the nozzle 271 and always pulls the nozzle 271 away from the center of the limiting ring 28. The end of the reaction rope 272 away from the nozzle 271 is fixed to the lower wall of the limiting ring 28.

[0049] The outer wall of the limiting ring 28 is provided with a rotating bead 29 and a spring piece 37. The limiting ring 28 is rotatably connected to the outer cover box 21 through the rotating bead 29, and the rotation range of the limiting ring 28 is limited by the spring piece 37. The rotation range of the limiting ring 28 is 0-2cm.

[0050] The sand supply module includes a sand supply pipe 25 and a sand passage ring pipe 32. The end of the sand supply pipe 25 away from the outer cover box 21 is connected to the sand blasting module 42. The sand passage ring pipe 32 is connected to the sand supply pipe 25. The sand passage ring pipe 32 is set above the protective ball cover 31 and passes through the protective ball cover 31 through a flexible tube to connect with all the sand blasting heads 27. The sand blasting module 42 is fixed to the side wall of the laser drilling host 11.

[0051] The composite burr removal module 2 also includes an air supply pipe 26 and an air circulation ring pipe 33. The end of the air supply pipe 26 away from the outer cover box 21 is connected to an air supply module 41, which is fixed to the side wall of the laser drilling host 11.

[0052] Ventilation ring pipe 33 is also installed above the protective ball cover 31. Ventilation ring pipe 33 is connected to air supply pipe 26. Ventilation ring pipe 33 passes through the protective ball cover 31 through a hose and is used to spray air downward from the gap of the limiting groove 34.

[0053] The adjustment module includes an electrical box 24. An adjustment push rod 241 and an angle adjustment push rod 242 are fixedly installed inside the electrical box 24. An adjustment wire 22 is connected to the telescopic column of the adjustment push rod 241. The end of the adjustment wire 22 away from the adjustment push rod 241 is connected to the limiting ring 28. The limiting ring 28 is pulled to rotate by the dynamic change of the telescopic column of the adjustment push rod 241.

[0054] An angle-adjusting wire 23 is connected to the telescopic column of the angle-adjusting push rod 242. The end of the angle-adjusting wire 23 away from the angle-adjusting push rod 242 is connected to a ring-shaped series rope 36. Tension wires 35 are arrayed on the series rope 36. Each tension wire 35 corresponds to a protective ball cover 31, and all tension wires 35 pass through the corresponding protective ball cover 31. They are then fixedly connected to the column body of the sandblasting head 27. The angle adjustment push rod 242 pulls all the sandblasting heads 27 to retract their angle by extending the telescopic column.

[0055] By introducing the composite burr removal module 2, burr removal can be completed simultaneously during the laser head retraction process, which greatly improves processing efficiency and automation.

[0056] Its workflow follows a closed-loop control logic of "detection-decision-execution", and the specific principle is as follows:

[0057] Initial positioning and laser drilling: The laser drilling host 11 moves to the designated position of the aluminum alloy curtain wall frame according to the preset program and emits a laser beam to complete the initial forming of the hole.

[0058] Real-time quality inspection: After drilling is completed, but before the laser head retracts, the integrated industrial inspection module 51 is immediately activated. This module integrates a laser scanner and an image processor to perform high-speed scanning of the newly formed hole.

[0059] Data Acquisition: The laser scanner emits a laser beam and acquires point cloud data of the inner wall of the hole by measuring the time of flight or using triangulation. The image processor then acquires high-resolution two-dimensional images of the hole to identify the morphology of edge burrs.

[0060] Geometric parameter calculation: The processor performs a fusion algorithm analysis on point cloud data and images to calculate three key parameters in real time: hole diameter D, center position O, and roundness error ΔR of the hole shape. The measurement frequency can reach 9.4kHz, ensuring data acquisition is completed within milliseconds.

[0061] Tool retraction and composite burr removal: After receiving data from the industrial detection module 51, the control system instructs the laser head to begin retraction. Simultaneously, the composite burr removal module 2 is activated, entering sandblasting mode.

[0062] Dynamic path planning: The adjustment module calculates the starting point and path of sandblasting in real time based on the received hole diameter D and position data.

[0063] Precise alignment: The adjustment module controls each blasting head 27 to ensure that the blasting point is precisely adjusted to 2-3mm outside the hole before blasting begins. This initial position is designed to first remove the raised burrs caused by the heat-affected zone at the edge of the hole.

[0064] Gradual-shrink sandblasting: During the sandblasting process, the adjustment module continuously receives position feedback from the industrial detection module 51. If closed-loop control is performed, or according to the preset mathematical model related to the retraction speed, the spray angle and focus of the sandblasting head 27 are dynamically controlled, so that the sandblasting range gradually shrinks from the hole edge radius R+δ towards the hole center, and finally converges at the hole center.

[0065] The mathematical model for a tapering path can be represented as:

[0066] Let the distance from the sandblasting focus to the center of the hole be r(t), the retraction speed be v, and the initial sandblasting radius be... = +2mm, total sandblasting time is T, then , where O≤t≤T, and R is the radius of the hole.

[0067] Burr removal mechanism: High-speed jets of diamond abrasive particles violently impact the burrs and slag at the edge of the hole, removing them through micro-cutting and erosion. Simultaneously, because the blasting trajectory is gradually tapering, it can uniformly smooth the burrs on the entire hole wall, creating a smooth chamfer.

[0068] Sandblasting media recovery and anti-diffusion: During sandblasting, the air supply module 41 sprays high-pressure air downwards through the air supply pipe 26 and the ventilation ring pipe 33. This air curtain has two functions: first, it uses the Coanda effect to confine the sprayed diamond abrasive to the pore area, preventing it from spreading to the curtain wall surface and causing scratches; second, it blows away the residual sand and dust from the workpiece surface after sandblasting, achieving self-cleaning.

[0069] To more clearly illustrate the technical solution, the workflow of the core module is broken down below.

[0070] Industrial Inspection Module 51 Process Analysis:

[0071] This module is the system's "eye," responsible for precisely guiding the burr removal process. Process steps:

[0072] Triggering activation: The laser drilling completion signal triggers the industrial detection module 51.

[0073] Image and laser scanning: Laser scanners scan the contours of holes, while industrial cameras capture high-definition images.

[0074] Feature extraction: The image processor analyzes the image to extract the distribution area and height of the burrs; the laser scanning data analyzes the boundary and depth of the holes.

[0075] Data fusion and calculation: By fusing two types of data, the precise coordinates of the hole center, the diameter value, and the average thickness of the burr are calculated.

[0076] Data transmission: The calculated geometric parameters are packaged and sent to the central controller and regulation module.

[0077] Analysis of the collaborative workflow between the adjustment module and the sandblasting head 27:

[0078] This module is the "brain and hand" of the system, responsible for performing precise sandblasting actions.

[0079] Process steps:

[0080] Command reception: Receive hole geometry parameters from industrial inspection module 51.

[0081] Sandblasting path calculation: Calculate the sandblasting starting point 2-3mm outside the hole and the retraction speed. Solve the action of the control adjustment push rod 241 and the angle adjustment push rod 242.

[0082] Adjusting the blasting range of the nozzle position: The adjustment push rod 241 actuates, pulling the limiting ring 28 slightly within the outer casing 21 by 0-2cm via the adjustment screw 22. The rotation of the limiting ring 28 causes the entire blasting head 27 to rotate circumferentially, ensuring that the radial position of the blasting head 27 is aligned with the edge of the hole.

[0083] Nozzle angle fine adjustment: The angle adjustment push rod 242 actuates, pulling the connecting rope 36 and the tension wire 35 via the angle adjustment screw 23. The tension wire 35 pulls the column of the sandblasting head 27. Since the support plate 273 of the sandblasting head 27 is rotatably set within the limiting groove 34, when pulled in the opposite direction, the spray angle of the nozzle 271 will converge towards the center. The reaction force rope 272 provides a reset pull, forming a dynamic balance with the angle adjustment push rod 242, achieving precise angle control.

[0084] Synchronous sandblasting: While the angle and position are being adjusted, the sand supply module is activated, and the diamond abrasive is sprayed from the nozzle 271 through the sand supply pipe 25, the sand passage ring pipe 32 and the hose, and burrs are removed along the calculated tapering path.

[0085] Extremely high processing efficiency and integration: The laser drilling and deburring processes are combined into one. By performing sandblasting simultaneously during the laser head retraction process, the time for transferring workpieces between different devices and the time for secondary clamping are eliminated. The single-hole processing cycle can be shortened by 30%-50%, making it particularly suitable for large-scale, high-density hole group processing in the curtain wall industry.

[0086] Adaptive intelligent deburring with high precision: Relying on real-time feedback from the industrial detection module 51 and dynamic control from the adjustment module, the sandblasting path is adaptively adjusted. Unlike traditional fixed sandblasting, the "gradually narrowing sandblasting path" can precisely treat the edges of holes in the burr area, avoiding the problems of over-sandblasting damaging the base material or under-sandblasting leaving burr residue.

[0091] S3. Based on geometric parameters, the adjustment module controls the sandblasting head 27 of the composite burr removal module 2 so that its sandblasting point is aligned with the predetermined position outside the hole.

[0092] S4. During the laser head retraction process, the composite burr removal module 2 starts sandblasting, and at the same time, the adjustment module dynamically shrinks and closes the sandblasting range according to the preset path to perform gradual sandblasting treatment on the holes.
