Description

Technical Field

[0001] This utility model belongs to the field of rearview mirror cutting equipment, and relates to a rearview mirror cutting equipment with a double-inlet and double-outlet structure. Background Technology

[0002] Laser cutting equipment focuses the laser emitted by the laser into a high-power-density laser beam through an optical path system, irradiates the surface of the workpiece to make it reach the melting or boiling point, and then uses high-pressure gas coaxial with the beam to blow away the molten or vaporized metal, thereby completing the cutting.

[0003] In the automotive rearview mirror manufacturing process, current laser cutting equipment for rearview mirrors generally adopts a single-in, single-out structure. The laser cutting mechanism moves along the direction defined by the gantry bracket to perform coating removal cutting on the rearview mirror. While the laser cutting mechanism itself has high cutting efficiency, the loading speed of the rearview mirror cannot match it; the loading speed lags behind the cutting speed. This prevents the laser cutting equipment from fully utilizing its high-efficiency cutting advantages, limiting overall efficiency improvement and impacting production efficiency and capacity.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0060] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0061] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0062] See Figures 1-3 As shown, a rearview mirror cutting device includes a machine base 1, on which a laser cutting mechanism 2, a dual-workstation loading platform 3, a rearview mirror loading mechanism 4, and a rearview mirror unloading mechanism 5 are installed. Through the coordinated cooperation between the various components, the automated cutting operation of the rearview mirror is realized.

[0063] Machine base 1, which serves as the supporting foundation for the entire equipment, is made of high-strength and high-stability metal material, and has a marble tabletop on its upper surface to ensure that the cutting accuracy is not affected by factors such as vibration during equipment operation.

[0064] A dual-workstation displacement platform 3 is arranged horizontally on the machine base 1. The dual-workstation displacement platform 3 includes a first linear motor and two first moving platforms 31 mounted on the first linear motor. The first linear motor, as the power source, features high precision, high speed, and high responsiveness, and can accurately control the moving position and speed of the two first moving platforms. Each first moving platform 31 is equipped with a placement table 32 for placing the rearview mirror. Each placement table 32 has several suction cups to ensure the rearview mirror is placed stably and to prevent shaking during the cutting process. In use, driven by the first linear motor, both placement tables 32 can move to the cutting position of the laser cutting mechanism 2, where the laser cutting mechanism 2 completes the film removal operation on the rearview mirror.

[0065] The rearview mirror loading mechanism 4 is set on the machine base 1 on both sides of the laser cutting mechanism 2. The rearview mirror loading mechanism 4 is longitudinally distributed and has a shaping station on it for positioning the rearview mirror, so that the moving suction cup 51 of the rearview mirror unloading mechanism 5 can grab the rearview mirror product at the shaping station.

[0066] The rearview mirror unloading mechanism 5 corresponds to the rearview mirror loading mechanism 4 and is located above the rearview mirror loading mechanism 4. The rearview mirror unloading mechanism 5 has a movable suction cup 51 that can move along a predetermined track. This movable suction cup adopts high-performance vacuum adsorption technology, with strong and stable adsorption force, and can reliably grasp and transfer the rearview mirror.

[0067] In use, the mobile suction cup 51 is used to grab the rearview mirror positioned at the shaping station and transfer it to the storage table 32 at the processing station; when the first mobile platform 31 returns the product cut at the cutting station to the processing station, the mobile suction cup 51 can adsorb the product at the processing station and move it to the unloading station.

[0068] The machine 1 is also equipped with a control cabinet 6 and a protective cover 7. The protective cover 7 is used to cover the laser cutting mechanism 2, the double-workstation loading platform 3, the rearview mirror loading mechanism 4, and the rearview mirror unloading mechanism 5, etc., and to protect the internal components of the equipment.

[0069] Of course, this rearview mirror cutting equipment also has a power supply system, a gas supply system, and a vacuum system to ensure normal operation. The control cabinet 6 has a built-in PLC controller with a control system. By writing precise control programs, it achieves coordinated control of the laser cutting mechanism 2, the double-workstation loading platform 3, the rearview mirror loading mechanism 4, and the rearview mirror unloading mechanism 5. An operation panel 8 is located on the outside of the protective cover 7. The operation panel 8 facilitates debugging and operation by on-site personnel. Its interface is simple and clear, allowing operators to easily set various parameters of the equipment and monitor its operating status.

[0070] like Figure 4 As shown, the rearview mirror loading mechanism 4 includes a first conveying bracket 41, which is made of high-strength aluminum alloy, is lightweight and stable, and is arranged horizontally along the conveying direction of the rearview mirror. Rotating shafts 42 are installed at both ends of the bracket, and the rotating shafts 42 are connected to the first conveying bracket 41 via bearings to ensure flexible rotation.

[0071] One of the rotating shafts 42 is driven by the first motor 43 via a pulley assembly. The pulley assembly consists of a driving pulley, a driven pulley, and a transmission belt, achieving efficient and stable power transmission. Both rotating shafts 42 are equipped with synchronous pulleys, and a synchronous belt 44 is fitted between the two synchronous pulleys. The surface of the synchronous belt 44 has anti-slip texture, which can effectively transport the rearview mirror.

[0072] The shaping station is located at the rear end of the first conveying bracket 41 along the rearview mirror conveying direction. Two sets of calibration components 45 and 46 are provided here, arranged in a cross shape. Each calibration component 45 and 46 is equipped with a synchronously movable stop 47 at both ends. The stop 47 is driven by a cylinder and can accurately limit the rearview mirror conveyed to the shaping station, thereby completing the positioning.

[0073] Specifically, in this embodiment, the two calibration components 45 and 46 have identical structures. The following detailed explanation uses calibration component 45 as an example. Figure 5As shown, the calibration assembly 45 includes a calibration base plate 451, which is made of high-strength stainless steel with a finely polished surface to ensure flatness. A first synchronous pulley 452 and a second synchronous pulley 453 are pivotally mounted at both ends via bearing seats. High-precision bearings are used inside the bearing seats to ensure smooth and wobbly rotation of the synchronous pulleys. A first synchronous belt 454 is fitted between the first synchronous pulley 452 and the second synchronous pulley 453. The first synchronous belt 454 is made of high-strength rubber with anti-slip textures on its surface, effectively transmitting power and preventing slippage.

[0074] A first linear slide rail 455 is mounted on the calibration base plate 451 on one side of the first synchronous belt 454. The first linear slide rail 455 has high precision and good wear resistance. A first guide member 456 and a second guide member 457 are slidably mounted on it via a slider. One end of the first guide member 456 is fixedly connected to one side of the first synchronous belt 454 via a clamping plate, and a stop member 47 is provided on the first guide member 456. Similarly, one end of the second guide member 457 is fixedly connected to the other side of the first synchronous belt 454 via a clamping plate, and a stop member 47 is also provided on the second guide member 457. A calibration cylinder 458 is also provided on the calibration base plate 451. The piston end of the calibration cylinder 458 is fixedly connected to the second guide member 457. When the calibration cylinder 458 is activated, the first guide member 456 and the second guide member 457 can move synchronously in opposite directions through the transmission of the first synchronous belt 454.

[0075] In this embodiment, the gear shift component 47 includes a gear shift base. The gear shift base is made of aluminum alloy, which is lightweight and has high strength. A roller is mounted on the base via a bearing. A guide wheel is sleeved on the roller. The guide wheel has a smooth surface, which can reduce the friction when in contact with the rearview mirror and avoid scratching the rearview mirror.

[0076] like Figure 6 As shown, the rearview mirror unloading mechanism 5 includes a truss 55, which is welded from high-strength square steel, resulting in a stable structure and strong load-bearing capacity. It is securely mounted on the machine base 1 via a fixing bracket. A second linear motor 52 is mounted on the truss 55, possessing high-precision and high-speed driving characteristics. A second movable platform 53 is mounted on the truss 55, connected to the mover of the second linear motor 52, allowing it to move horizontally along the truss 55 under its drive. A vertical cylinder 54 is fixed on the second movable platform 53, with its piston end fixedly connected to a movable suction cup 51. The vertical lifting and lowering of the movable suction cup 51 can be achieved by extending and retracting the vertical cylinder 54.

[0077] like Figure 7As shown, the movable suction cup 51 includes a suction cup platform 511, which is made of aluminum alloy, making it lightweight and high-strength. It has an outwardly extending arm 512, on which a sliding groove 514 is provided. The suction cup 513 is secured to the sliding groove 514 by bolts. The position of the suction cup 513 on the arm 512 can be adjusted by loosening the bolts to accommodate the gripping needs of rearview mirrors of different sizes.

[0078] like Figure 8 , Figure 9 As shown, in order to meet different cutting needs and ensure that the rearview mirror is at a precise angle during cutting, the first moving platform 31 is equipped with an angle adjustment component for adjusting the deflection angle of the platform 32.

[0079] In this angle adjustment assembly, the rotating bracket 33 is fixed below the platform 32. The rotating bracket 33 is made of high-strength steel, has a stable structure, and can reliably support the platform 32. Its lower end is fixedly connected to the rotating shaft 34, which is made of high-precision, high-strength alloy steel to ensure rotational stability and accuracy. Both ends of the rotating shaft 34 are fixed to the carrier plate 36 via bearing seats. The bearing seats use high-precision bearings to reduce friction and ensure smooth rotation of the rotating shaft 34. The carrier plate 36 is fixedly connected to the first movable platform 31.

[0080] One end of the rotating shaft 34 is connected to the drive assembly 35 via a coupling. The coupling has good buffering and shock absorption performance and can effectively transmit power. The drive assembly 35 includes a servo motor and a reducer that are linked with the control system. The servo motor has a fast response speed and high control precision, while the reducer can reduce the speed and increase the torque, together achieving precise adjustment of the deflection angle of the platform 32.

[0081] In summary, the embodiments of this utility model achieve the following technical effects: The rearview mirror cutting equipment provided by this utility model, through the cooperation of the rearview mirror loading mechanism 4, the rearview mirror unloading mechanism 5 and the dual-workstation displacement platform 3, enables the laser cutting mechanism 2 to simultaneously perform cutting operations on two products, thereby improving the overall cutting efficiency of the rearview mirror cutting equipment.
