[0001] The present invention relates to the technical field of laser engraving machines, and particularly to an automatic plastic shell laser engraving machine. Background Art

[0002] A laser engraving machine, also called a laser carving machine, is a device that uses a high-energy density laser beam to locally irradiate the surface of a material, causing the surface of the material to instantly melt, vaporize, or change color, thereby leaving a permanent mark on the surface of the material. It mainly consists of a laser generator, a galvanometer scanning system, a focusing system, a computer control system, etc. The laser generator generates a high-energy laser beam. The galvanometer scanning system is responsible for controlling the scanning path of the laser beam. The focusing system focuses the laser beam onto a tiny area on the surface of the material.

The upper part of the connecting rod is fixedly connected with a positioning plate. The bottom ends of both sides of the positioning plate are fixedly connected with limiting blocks. A limiting groove is formed on the upper surface of the positioning table. One end above the cabinet body is fixedly connected with a lifting column. The surface of the lifting column is slidably connected with a lifting block. One side of the lifting block is fixedly connected with a control box. One end of the control box is connected with a push rod. The surface of one end of the push rod is fixedly connected with a laser head.

[0007] Preferably, multiple groups of foot supports are arranged at the bottom of the cabinet body and are symmetrically distributed at the four corners of the bottom of the cabinet body with respect to the central axis of the cabinet body.

[0008] Preferably, the sliding mechanism includes a fixed column, a moving frame, a first chute, a first motor, a lead screw, an auxiliary rod, a first slider, a support frame, a hydraulic cylinder, a hydraulic rod and an electromagnetic chuck. The upper part of the cabinet body is fixedly connected with a fixed column. The upper surface of the fixed column is fixedly connected with a moving frame. A first chute is formed on the surface of the moving frame. One end of the moving frame is fixedly connected with a first motor. The inner end of the first motor is fixedly connected with a lead screw. The inner wall of the first chute is fixedly connected with an auxiliary rod. The outer walls of both the lead screw and the auxiliary rod are slidably connected with a first slider. The outer surface of the first slider is fixedly connected with a support frame. The surface of the support frame is fixedly connected with a hydraulic cylinder. The inside of the hydraulic cylinder is slidably connected with a hydraulic rod. The bottom of the hydraulic rod is fixedly connected with an electromagnetic chuck.

First, the second motor starts to drive the threaded rod to rotate. Since the moving block is threadedly connected to the threaded rod, and the second slider at the bottom of the moving block slides in the moving groove on the surface of the base, this design ensures that the moving block can only move in a straight line along the moving groove when the threaded rod rotates. At the same time, the connecting rod transmits the movement of the moving block to the positioning plate, causing the positioning plate to move in the second sliding groove above the positioning table, and the limiting block at the bottom of the positioning plate slides in the limiting groove, further ensuring the accuracy and stability of the movement of the positioning plate. Thus, it can accurately position the plastic shell in the horizontal direction, avoiding the position deviation caused by human factors like manual engraving, and ensuring that the starting position of each engraving is accurate. Then, the lifting column installed above one end of the cabinet comes into play. The control box can control the lifting block to slide on the lifting column to adjust the height of the laser head in the vertical direction. Through this precise height adjustment, it can adapt to plastic shells of different thicknesses, keep the laser head at an appropriate distance from the surface of the plastic shell, ensure that the laser beam can accurately focus on the plastic shell, and improve the engraving accuracy. Different from manual engraving, this automatic height adjustment is not affected by the state and skill level of workers and can always ensure stable working parameters. Finally, the control box precisely controls the up and down position of the laser head through the push rod. The laser head emits a laser beam with a high energy density. During the entire positioning laser engraving process, each component works together to achieve high-precision positioning and laser engraving of the plastic shell, greatly improving the engraving efficiency and the consistency of product quality, and avoiding the problems of uneven quality and low efficiency caused by individual differences and unstable states of workers in manual engraving.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: an automatic plastic shell laser engraving machine, including a cabinet body 1, a cabinet door 2 is installed on the surface of the cabinet body 1, a handle 3 is fixedly connected to the surface of the cabinet door 2, a foot support 4 is fixedly connected to the bottom of the cabinet body 1, a silo 5 is placed on the upper surface of the cabinet body 1, a sliding mechanism 6 is arranged above the cabinet body 1, and a positioning laser engraving mechanism 7 is arranged above the cabinet body 1

[0023] The positioning laser engraving mechanism 7 includes a base 701, a positioning table 702, a second motor 703, a threaded rod 704, a stopper 705, a moving block 706, a second slider 707, a moving groove 708, a connecting rod 709, a second chute 710, a positioning plate 711, a limiting block 712, a limiting groove 713, a lifting column 714, a lifting block 715, a control box 716, a push rod 717 and a laser head 718. The upper surface of the cabinet body 1 is fixedly connected with the base 701. The two sides of the base 701 are fixedly connected with the positioning tables 702. One side surface of the positioning table 702 is fixedly connected with the second motor 703. The inner end of the second motor 703 is fixedly connected with the threaded rod 704. A stopper 705 is arranged in the middle of the threaded rod 704. The surface of the threaded rod 704 is threadedly connected with the moving block 706. The bottom of the moving block 706 is fixedly connected with the second slider 707. A moving groove 708 is formed on the surface of the base 701. The upper surface of the moving block 706 is fixedly connected with the connecting rod 709. A second chute 710 is formed on the upper surface of the positioning table 702. The upper part of the connecting rod 709 is fixedly connected with the positioning plate 711. The bottom ends of both sides of the positioning plate 711 are fixedly connected with the limiting blocks 712. A limiting groove 713 is formed on the upper surface of the positioning table 702. One end above the cabinet body 1 is fixedly connected with the lifting column 714. The surface of the lifting column 714 is slidably connected with the lifting block 715. One side of the lifting block 715 is fixedly connected with the control box 716. One end of the control box 716 is connected with the push rod 717. The surface of one end of the push rod 717 is fixedly connected with the laser head 718. Through the setting of the positioning laser engraving mechanism 7, when the automatic plastic shell laser engraving machine works, the positioning laser engraving mechanism 7 starts to operate to overcome the disadvantages of traditional manual engraving. First of all, the second motor 703 starts, driving the threaded rod 704 to rotate. Since the moving block 706 is threadedly connected with the threaded rod 704, and the second slider 707 at the bottom of the moving block 706 slides in the moving groove 708 on the surface of the base 701, this design ensures that the moving block 706 can only move linearly along the moving groove 708 when the threaded rod 704 rotates. At the same time, the connecting rod 709 transmits the movement of the moving block 706 to the positioning plate 711, causing the positioning plate 711 to move in the second chute 710 above the positioning table 702, and the limiting blocks 712 at the bottom of the positioning plate 711 slide in the limiting groove 713, further ensuring the accuracy and stability of the movement of the positioning plate 711, so as to accurately position the plastic shell in the horizontal direction, avoiding the position deviation caused by human factors like manual engraving, and ensuring that the starting position of each engraving is accurate. Then, the lifting column 714 installed above one end of the cabinet body 1 comes into play. The control box 716 can control the lifting block 715 to slide on the lifting column 714 to adjust the height of the laser head 718 in the vertical direction. Through this precise height adjustment, it can adapt to plastic shells of different thicknesses, keep the laser head 718 at an appropriate distance from the surface of the plastic shell, ensure that the laser beam can accurately focus on the plastic shell, and improve the engraving accuracy. Different from manual engraving,This automatic height adjustment is not affected by the worker's state and skill level, and can always ensure stable working parameters. Finally, the control box 716 precisely controls the up and down position of the laser head 718 through the push rod 717. The laser head 718 emits a laser beam with a high energy density. During the entire positioning and laser engraving process, each component works together to achieve high-precision positioning and laser engraving of the plastic shell, greatly improving the engraving efficiency and the consistency of product quality, and avoiding the problems of uneven quality and low efficiency caused by individual differences and unstable states of workers in manual engraving.

[0024] Furthermore, multiple groups of foot supports 4 are provided at the bottom of the cabinet body 1, and are symmetrically distributed at the four corners of the bottom of the cabinet body 1 with respect to the central axis of the cabinet body 1. Due to the need for high precision in laser engraving, if the cabinet body 1 is unstable, vibrations may be transmitted to the positioning and laser engraving mechanism 7, resulting in deviations during engraving by the laser head 718. The symmetrically distributed foot supports 4 can effectively absorb and isolate external vibrations, reduce the impact on engraving accuracy, and ensure the accuracy of the patterns and characters engraved on the plastic shell.

[0025] Further, the sliding mechanism 6 includes a fixed column 601, a moving frame 602, a first sliding groove 603, a first motor 604, a lead screw 605, an auxiliary rod 606, a first slider 607, a support frame 608, a hydraulic cylinder 609, a hydraulic rod 610, and an electromagnetic chuck 611. A fixed column 601 is fixedly connected above the cabinet body 1. The upper surface of the fixed column 601 is fixedly connected with a moving frame 602. A first sliding groove 603 is formed on the surface of the moving frame 602. One end of the moving frame 602 is fixedly connected with a first motor 604. The inner end of the first motor 604 is fixedly connected with a lead screw 605. An auxiliary rod 606 is fixedly connected to the inner wall of the first sliding groove 603. A first slider 607 is slidably connected to the outer wall surfaces of both the lead screw 605 and the auxiliary rod 606. The outer surface of the first slider 607 is fixedly connected with a support frame 608. A hydraulic cylinder 609 is fixedly connected to the surface of the support frame 608. A hydraulic rod 610 is slidably connected inside the hydraulic cylinder 609. The bottom of the hydraulic rod 610 is fixedly connected with an electromagnetic chuck 611. Through the setting of the sliding mechanism 6, when it is necessary to move the plastic shell, the sliding mechanism 6 starts to work. First, the first motor 604 is started to drive the rotation of the lead screw 605. Since the lead screw 605 is threadedly connected to the first slider 607 and the first slider 607 slides on the auxiliary rod 606 at the same time, the auxiliary rod 606 plays a role in restricting the rotation of the first slider 607 and providing a linear motion guide for it. Therefore, when the lead screw 605 rotates, the first slider 607 will move linearly along the lead screw 605 and the auxiliary rod 606. The linear motion of the first slider 607 drives the outer support frame 608 to move synchronously, thereby realizing the position adjustment in the horizontal direction. This way of cooperating with the motor, lead screw, and slider can accurately control the moving distance and speed to meet different working requirements. When the support frame 608 moves above the target position, the hydraulic cylinder 609 starts to work. The hydraulic rod 610 inside the hydraulic cylinder 609 performs telescopic motion under the hydraulic action. The electromagnetic chuck 611 at the bottom of the hydraulic rod 610 moves up and down accordingly. When the electromagnetic chuck 611 approaches the plastic shell, the electromagnetic chuck 611 is energized to generate magnetic force, firmly sucking the plastic shell. Then, through the retraction action of the hydraulic rod 610, the plastic shell is lifted from the material bin 5 or other placement positions. After that, if it is necessary to move the plastic shell to a new position again, the first motor 604 is started again to make the first slider 607 drive the support frame 608, the hydraulic cylinder 609, the hydraulic rod 610, the electromagnetic chuck 611, and the adsorbed plastic shell to move to the designated position together, completing the transportation and positioning of the plastic shell and preparing for the subsequent laser engraving process. The whole process realizes the flexible and accurate movement of the plastic shell in the horizontal and vertical directions, improving the work efficiency and automation degree.

[0026] Furthermore, the lead screw 605 and the first motor 604 cooperate with each other to form a rotating structure. There are two sets of auxiliary rods 606 symmetrically arranged with respect to the horizontal central axis of the lead screw 605. Through the arrangement of the first motor 604, the lead screw 605 and the auxiliary rods 606, the lead screw 605 and the first motor 604 cooperate with each other to form a rotating structure. This design ensures the accuracy of power transmission. The first motor 604, as the power source, can stably drive the rotation of the lead screw 605 and provide accurate power for the movement of the first slider 607. There are two sets of auxiliary rods 606 symmetrically arranged with respect to the horizontal central axis of the lead screw 605, providing balanced and stable support for the first slider 607. During the movement of the first slider 607, the two sets of auxiliary rods 606 can effectively prevent it from tilting or shaking, ensuring that it moves linearly along the axial direction of the lead screw 605, thereby improving the accuracy and stability of the entire sliding mechanism 6 during horizontal movement.

[0027] Furthermore, the position of the first slider 607 corresponds to the position of the first chute 603, and the outer wall size of the first slider 607 matches the inner wall size of the first chute 603. Through the arrangement of the first chute 603 and the first slider 607, when the lead screw 605 rotates to drive the movement of the first slider 607, the first chute 603 restricts the degree of freedom of the first slider 607, enabling it to move only along a predetermined straight trajectory, avoiding deviation, ensuring the accuracy of the plastic shell during horizontal movement, and being beneficial to subsequent laser engraving operations.

[0028] Furthermore, the threaded rod 704 and the second motor 703 cooperate with each other to form a rotating structure. The threads of the threaded rod 704 are symmetrically distributed with respect to the vertical central axis of the stop block 705. Through the arrangement of the threaded rod 704, the threaded rod 704 and the second motor 703 cooperate with each other to form a rotating structure, enabling the rotational movement of the second motor 703 to be effectively converted into the rotational movement of the threaded rod 704 and providing power for the movement of the moving block 706. This structure is simple and reliable, can accurately control the movement of the moving block 706, and achieve precise adjustment of the horizontal position of the positioning plate 711. The threads of the threaded rod 704 are symmetrically distributed with respect to the vertical central axis of the stop block 705, ensuring that when the threaded rod 704 rotates, the moving blocks 706 on both sides can move towards or away from each other synchronously and stably. This symmetrical design is crucial for maintaining the balance and stability of the positioning plate 711 during movement, avoiding positioning deviation caused by uneven forces on both sides, and improving the positioning accuracy of the positioning and laser engraving mechanism 7 in the horizontal direction.

[0029] Furthermore, the position of the second slider 707 corresponds to the position of the moving slot 708, and the outer wall dimension of the second slider 707 matches the inner wall dimension of the moving slot 708. Through the arrangement of the second slider 707 and the moving slot 708, when the moving block 706 moves as the threaded rod 704 rotates, the second slider 707 slides within the moving slot 708. This cooperation provides stable support and precise guidance for the movement of the moving block 706, ensuring the stability of the linear movement of the moving block 706 in the horizontal direction, further improving the positioning accuracy of the positioning laser engraving mechanism 7 in the horizontal direction, and facilitating the accurate performance of the laser engraving operation.

[0030] Furthermore, the position of the limiting block 712 corresponds to the position of the limiting slot 713, and the outer wall dimension of the limiting block 712 matches the inner wall dimension of the limiting slot 713. Through the arrangement of the limiting block 712 and the limiting slot 713, more precise guidance is provided for the movement of the positioning plate 711. During the movement of the positioning plate 711, the limiting block 712 slides within the limiting slot 713, strictly restricting the movement direction of the positioning plate 711, further improving the positioning accuracy, and capable of controlling the positioning error of the plastic shell in the horizontal direction within an extremely small range, ensuring the accuracy when the laser head 718 performs laser engraving on the plastic shell and improving the product quality.

[0031] Working principle: First, when the automatic plastic shell laser engraving machine starts working, the plastic shells in the material bin 5 are waiting to be processed. First, the sliding mechanism 6 is activated. The first motor 604 drives the lead screw 605 to rotate. The first slider 607 moves linearly under the combined action of the lead screw 605 and the auxiliary rod 606, thereby driving the support frame 608 to move. When the support frame 608 reaches the appropriate position above the material bin 5, the hydraulic cylinder 609 drives the hydraulic rod 610 to extend, bringing the electromagnetic chuck 611 close to the plastic shell. The electromagnetic chuck 611 is energized to generate magnetic force to adsorb the plastic shell. Then the hydraulic rod 610 retracts to lift the plastic shell. If it is necessary to move the plastic shell to the positioning laser engraving mechanism 7, the first motor 604 is started again to accurately transport the plastic shell above the positioning laser engraving mechanism 7. In the positioning laser engraving mechanism 7, the second motor 703 is started to drive the threaded rod 704 to rotate. The moving block 706 moves linearly under the cooperation of the threaded rod 704, the second slider 707 and the moving groove 708, and drives the positioning plate 711 to move in the second chute 710 through the connecting rod 709. At the same time, the limiting block 712 slides in the limiting groove 713 to accurately adjust the horizontal position of the positioning plate 711, thereby accurately positioning the horizontal position of the plastic shell. After that, the control box 716 controls the lifting block 715 to slide on the lifting column 714 to adjust the height of the laser head 718 in the vertical direction, so that the laser head 718 maintains an appropriate distance from the surface of the plastic shell. The control box 716 then accurately controls the up and down position of the laser head 718 through the push rod 717. The laser head 718 emits a laser beam with a high energy density to engrave the plastic shell. During the whole process, multiple groups of foot supports 4 symmetrically distributed at the bottom of the cabinet 1 keep the equipment stable, effectively absorbing and isolating external vibrations and avoiding the influence of vibrations on the engraving accuracy. After the engraving is completed, the sliding mechanism 6 is started again to move the processed plastic shell to the designated collection area, and then the above steps are repeated to continuously carry out high-precision engraving processing on the plastic shell, greatly improving the production efficiency and product quality, and effectively overcoming the deficiencies of traditional manual engraving. The model of the first motor 604 is Y315S-2, the model of the hydraulic cylinder 609 is CDM2B25, and the model of the second motor 703 is YE2-132S-4. In this way, the use process of the automatic plastic shell laser engraving machine is completed.
