Description

Technical Field

[0001] This utility model mainly relates to the technical field of door and window profile processing equipment, specifically a profile punching and positioning system. Background Technology

[0002] Punching is an essential step in the production of door and window profiles. Traditionally, profile punching is done manually by marking lines, manually positioning, or using simple mechanical positioning methods. However, these methods generally suffer from low positioning accuracy, low efficiency, high labor intensity, and are prone to causing damage to the profile surface.

[0003] For example, some existing positioning and punching devices for aluminum profile processing (such as those described in patent CN215199191U) have relatively simple structures, but in actual operation, they are not very adaptable to different specifications of profiles, and there may still be inaccurate positioning or inconvenient operation during clamping and pushing.

[0004] Furthermore, while some continuous multi-directional punching devices for profiles (such as those described in patent CN102649143B) improve punching efficiency, they primarily focus on achieving multi-directional punching. There is still room for improvement in meeting the demand for high-precision positioning, especially when dealing with complex profiles or holes requiring high precision. The stability and accuracy of their positioning still need improvement. Currently available punching equipment, while achieving automation and improving efficiency, often neglects the extremely precise control of the punching position. This is particularly true for products like door and window profiles, which have extremely high dimensional accuracy requirements. Even minor positioning deviations can lead to product scrap, increasing production costs. Therefore, developing a profile punching positioning system that achieves precise positioning, is easy to operate, and effectively improves production efficiency is a pressing technical challenge in the current door and window profile manufacturing industry.

[0009] Furthermore, a longitudinal moving platform is provided on the longitudinal linear guide rail, a longitudinal moving motor is provided on the longitudinal moving platform, and the transverse linear guide rail is fixed on the longitudinal moving platform.

[0014] Furthermore, the base is welded from high-strength steel.

[0015] The beneficial effects of this utility model are: 1.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-3 The diagram shown is a schematic diagram of the relevant structure of a profile punching positioning system provided in this embodiment.

[0023] like Figure 1 As shown, a profile punching positioning system includes a support frame 1, a base 2 at the bottom of the support frame 1, the base 2 being welded from high-strength steel to ensure the stability and seismic resistance of the system, a flat work surface on the top of the base 2 for placing the door and window profiles to be processed, a longitudinal linear guide rail 3 on the base 2, a transverse linear guide rail 4 on the longitudinal linear guide rail 3, a pair of transverse moving platforms 5 on the transverse linear guide rail 4, and a punching actuator 9 above the longitudinal linear guide rail 3 and the transverse linear guide rail 4.

[0024] A vision recognition unit 10 is installed on the top of the support frame 1. The vision recognition unit 10 consists of a high-resolution industrial camera 18 and image processing software. The industrial camera 18 is mounted above the punching actuator 9, facing the profile working area. After the profile is fixed by the clamping mechanism, the industrial camera 18 acquires real-time images of the profile surface. The image processing software analyzes the images using a preset algorithm, automatically identifying the profile edges, preset positioning markers (such as pre-drilled holes or lines on the profile), or existing hole positions. Through sub-pixel-level edge detection and feature matching technology, the X and Y coordinates and rotation angle of the profile on the worktable are accurately calculated. The vision recognition unit 10 can effectively compensate for minor deviations in profile placement, ensuring the accuracy of subsequent positioning.

[0025] A laser ranging unit 11 is disposed on the side of the visual recognition unit 10 for non-contact precise measurement of the longitudinal position of the profile. The laser ranging unit 11 emits a laser beam, and by measuring the time difference or phase difference from the emission to the reception of the laser beam, the distance between the profile and the reference point is accurately calculated. The data of this unit is fused with that of the visual recognition unit 10 to further calibrate the longitudinal position of the profile, which is especially suitable for the precise positioning of long profiles.

[0026] The visual recognition unit 10 and the laser ranging unit 11 are the core of this system, used to achieve precise positioning of the punching position of the profile. An intelligent controller 12 is installed on the side of the support frame 1. The intelligent controller 12 consists of an industrial computer, a PLC programmable logic controller, and a human-machine interface, and is the "brain" of the entire system. The industrial computer is responsible for running the image processing software and the host computer control program, while the PLC is responsible for the precise control and data acquisition of the underlying equipment. The human-machine interface is a touch screen, through which operators can input punching parameters (such as profile type, hole coordinates, hole diameter, number of punches, etc.) and monitor the punching process, equipment status, and fault information in real time.

[0027] like Figure 2 As shown, the punching actuator 9 includes a hydraulic cylinder 13, which provides powerful punching force to ensure effective punching of profiles of various materials and thicknesses. A punch 14 is located at the bottom of the hydraulic cylinder 13, and a lower die holder 15 is located below the punch 14 for punching the positioned profile. The punch 14 and the lower die holder 15 are fixed on the support frame 1. The punch 14 and the lower die holder 15 can be quickly replaced according to punching requirements to adapt to punching dies with different hole diameters (such as round, square, and irregular holes) and shapes. During the punching process, the intelligent controller 12 precisely controls the stroke and speed of the hydraulic cylinder 13 to ensure punching quality and die life.

[0028] A longitudinal linear guide 3 is provided with a longitudinal moving platform 16, and a longitudinal moving motor 17 is provided on the longitudinal moving platform 16. A transverse linear guide 4 is fixed on the longitudinal moving platform 16. At least two transverse linear guides 4 are provided. Both the longitudinal linear guide 3 and the transverse linear guide 4 are high-precision rolling linear guides. Both the longitudinal moving motor 17 and the transverse moving motor 8 are high-precision servo motors.

[0029] The mobile platform receives positioning commands from the intelligent controller 12 and, based on the precise coordinate data provided by the vision recognition unit 10 and the laser ranging unit 11, drives the profile to move precisely along the longitudinal linear guide rail 3 and the transverse linear guide rail 4, accurately moving the position to be punched directly below the punching actuator 9. This platform boasts extremely high repeatability (±0.02mm) and rapid response, ensuring accurate punching positioning and high processing efficiency.

[0030] like Figure 3 As shown, a clamping clamp 6 is installed on the transverse moving platform 5, employing a pneumatic clamping device for reliable clamping of door and window profiles. The clamping surface of the clamping clamp 6 is made of a wear-resistant material with a high coefficient of friction to prevent the profile from slipping or its surface from being damaged during punching. The clamping force can be adjusted according to the material and thickness of the profile to ensure a firm clamping without deformation. The lower die base 15 and the clamping clamp 6 are on the same horizontal plane. A clamping cylinder 7 is installed on the clamping clamp 6, and a transverse moving motor 8 is installed on the side of the transverse moving platform 5. The motor receives commands from the controller and drives the clamping clamp 6 to move along the guide rail, thereby achieving rapid clamping and releasing of profiles of different widths.

[0031] The working principle of this embodiment is as follows: The operator first places the door and window profile to be processed on the clamping clamp 6 of the base 2, inputs or selects the corresponding punching parameters through the human-machine interface, and the intelligent controller 12 issues a command. The profile clamping mechanism automatically clamps the profile. The vision recognition unit 10 and the laser ranging unit 11 scan and measure the profile to obtain accurate positioning data. Based on the positioning data, the intelligent controller 12 calculates the deviation between the punching position and the punching execution mechanism 9, and instructs the moving platform to move precisely to move the punching position to directly below the punch 14. The punching execution mechanism 9 receives the command, and the hydraulic cylinder 13 drives the punch 14 downward to complete the punching operation. After punching is completed, the punch 14 is reset, and the moving platform moves to the next punching position. The above steps are repeated until all holes are punched. After all punching is completed, the clamping clamp 6 of the profile clamping mechanism releases the profile, and the operator removes the processed profile.

[0032] This utility model's profile punching positioning system integrates visual recognition, laser ranging, and high-precision CNC movement technology to achieve precise positioning and automated production of door and window profile punching. It effectively solves the drawbacks of traditional punching methods and significantly improves the production efficiency and product quality of door and window profiles.
