Description

Technical Field

[0001] This application relates to the field of automated equipment, and in particular to a laser processing apparatus and equipment. Background Technology

[0002] In the 3C industry, laser marking is widely used, especially for plastic products where high aesthetic standards are required. Conventional screen printing and labeling can become illegible over time due to damage, while laser marking provides permanent material modification and cannot be easily torn or erased unless the product itself is damaged. Laser marking is not only efficient and environmentally friendly, but also offers high precision and narrow line widths, enabling fine marking and improving product quality. Traditional technologies typically use conveyor belts to transport fixtures, with a processing module marking the workpieces above. However, because the processing module has a small processing range, each workpiece requires mechanical positioning, resulting in longer waiting times and lower efficiency. Utility Model Content

[0003] This application proposes a laser processing apparatus and equipment, which uses a lifting mechanism to perform a mechanical positioning of the fixture. After positioning, the fixture is driven independently, so that the workpieces in the fixture correspond to the processing modules respectively, resulting in high marking efficiency.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0033] This application discloses a laser processing apparatus, with reference to... Figures 1 to 3 The laser processing apparatus includes: a first conveying mechanism 10 for conveying a fixture along a first direction; a processing mechanism 20 including a processing module 21 disposed above the first conveying mechanism 10; a first driving mechanism 30 disposed on one side of the first conveying mechanism 10, the driving direction of the first driving mechanism 30 being along the first direction; a blocking mechanism 50 disposed at the driving end of the first driving mechanism 30 for blocking the fixture on the first conveying mechanism 10; a lifting mechanism 40 disposed at the driving end of the first driving mechanism 30 for docking with the fixture and lifting the fixture, so that the fixture is disengaged from the first conveying mechanism 10; the first driving mechanism 30 is also used to drive the lifting mechanism 40 and the fixture to move along the first direction, so that each workpiece on the fixture sequentially enters the processing range of the processing module 21.

[0034] In this embodiment, the lifting mechanism 40 and the fixture can be connected via a pin and hole structure. Alternatively, a groove corresponding to the fixture can be provided on the lifting end 42 of the lifting mechanism 40 to complete the connection. After the lifting end 42 of the lifting mechanism 40 moves from bottom to top and is positioned with the fixture, the lifting mechanism 40 continues to lift the fixture, causing it to disengage from the first conveying mechanism 10. After the fixture rises and disengages from the first conveying mechanism 10, the first driving mechanism 30 can drive the lifting mechanism 40 and the fixture to move synchronously along a first direction, so that each workpiece on the fixture enters the processing range of the processing module 21 in sequence, allowing the processing module 21 to mark each workpiece sequentially. The fixture is mechanically positioned only once by the lifting mechanism 40, eliminating the need for separate mechanical positioning of each workpiece, resulting in short waiting time and high marking efficiency.

[0035] It is worth noting that the laser processing device in this application embodiment is not limited to the single field of laser marking. It can be adapted to different processing modules according to different processing scenarios, so that the device can be used for laser engraving, laser hidden cutting, laser cutting and other working conditions.

[0036] In some embodiments, the laser processing apparatus further includes a limiting member 35 disposed at the driving end of the first driving mechanism 30 and located above the first conveying mechanism 10. The limiting member 35 is used to clamp the upper and lower ends of the fixture with the lifting mechanism 40. In this embodiment, by setting the limiting member 35, the fixture can be completely fixed, preventing the fixture from detaching from the lifting mechanism 40 due to inertia at the tail end of the lifting process. The fixture is defined by the lifting end 42 in the horizontal direction and clamped and fixed in the vertical direction.

[0037] Furthermore, the first conveying mechanism 10 includes two conveyor belts arranged side by side; the laser processing device also includes a first mounting member 31 located at the drive end of the first driving mechanism 30. The first mounting member 31 is located below the first conveying mechanism 10, and the material blocking mechanism 50 and the lifting mechanism 40 are located on the first mounting member 31 and between the two conveyor belts. In this embodiment, the lifting mechanism 40 includes a lifting cylinder 41 located on the first mounting member 31 and a receiving plate located at the upper end of the push rod of the lifting cylinder 41. The receiving plate constitutes the aforementioned lifting end 42. The receiving plate is provided with a plurality of pins, and the bottom of the fixture is provided with limiting holes corresponding to the pins. The pins can be inserted into the limiting holes to limit the horizontal direction of the fixture. The lifting cylinder 41 is located between the two conveyor belts and can lift the fixture and detach it from the conveyor belt. When there is no lifting requirement, the push rod of the lifting cylinder 41 retracts and will not interfere with the normal conveying of the fixture on the conveyor belt. Of course, in addition to using two parallel conveyor belts to transport the fixture, the first conveyor mechanism 10 can also use a double-row roller chain instead of a conveyor belt, with fixture positioning slots set between the chain links, and the chain driven by a variable frequency motor. The first drive mechanism 30 can be driven by a linear motor or a belt, and the electric cylinder can be replaced by a linear motor, with the mover directly connected to the first mounting part 31. A combination of a synchronous belt and a servo motor is used, with the drive end 33 connected to the belt, and the belt and drive end 33 connected by a belt clamping block. In addition, the above-mentioned lifting mechanism can also be replaced by an electric lead screw. The lifting cylinder 41 is replaced by a ball screw driven by a servo motor, and the lead screw nut is connected to the receiving plate, which can drive the receiving plate to rise and fall.

[0038] In some embodiments, the laser processing apparatus further includes a second mounting member disposed at the drive end of the first drive mechanism 30 and located above the first conveying mechanism 10. The second mounting member and the first mounting member 31 are spaced apart along the vertical direction, and a limiting member 35 is disposed on the second mounting member. In this embodiment, the first drive mechanism 30 may be an electric cylinder disposed on the outer side of the two conveyor belts and arranged parallel to the conveyor belts, with the drive end 33 of the electric cylinder facing the conveyor belts. Compared to the conveyor belts, the electric cylinders can provide higher positioning accuracy, ensuring that each workpiece is aligned with the processing range above.

[0039] The first mounting member 31 can be a first mounting plate mounted on the drive end 33, extending below the conveyor belt along a horizontal direction perpendicular to the first direction. The second mounting member 32 can be a second mounting plate mounted on the drive end 33, extending above the conveyor belt along a horizontal direction perpendicular to the first direction. The conveyor belt is positioned between the first mounting member 31 and the second mounting member 32, and the first mounting member 31, the second mounting member 32, and the components mounted on them can be translated along the first direction with the drive end 33 of the electric cylinder. The configuration of the first mounting member 31 and the second mounting member 32 provides a mounting position for the aforementioned lifting mechanism 40 and blocking mechanism 50. Of course, it also allows the components on them to not interfere with the conveying of the fixture on the conveyor belt in some operating conditions (where lifting and blocking fixtures are not required).

[0040] In some embodiments, the fixture has multiple mounting holes arranged side-by-side for mounting workpieces, with the mounting holes arranged along a first direction. The limiting member 35 has through holes corresponding to each mounting hole. In this embodiment, when the fixture is conveyed on the conveyor belt, the mounting holes on it are arranged along the first direction, and the workpiece is inserted into the mounting holes for initial positioning. At this time, there is still a certain gap between the workpiece and the mounting hole. The limiting member 35 can be a limiting plate, with through holes on the limiting plate also arranged along the first direction. It is used to accurately position the workpiece. The workpiece is pushed up by the fixture and inserted into the through hole, and the workpiece can be completely constrained by the through hole. In addition, to improve the smoothness of the docking between the workpiece and the through hole, a chamfer can be made at the lower end of the through hole to form a guide slope to assist the workpiece in docking with the through hole.

[0041] In some embodiments, the blocking mechanism 50 includes: a blocking member rotatably mounted on a first mounting member and located between two conveyor belts, the blocking member being disposed on one side of the lifting mechanism 40; and a blocking drive member disposed on the first mounting member for driving the blocking member to rotate, so that one end of the blocking member facing the lifting mechanism 40 can be raised to block the fixture. In this embodiment, the blocking drive member may be a blocking cylinder 51 disposed on the first mounting member, the blocking cylinder 51 being disposed on the side of the lifting cylinder 41 near the tail end of the conveyor belt. A hinge seat mounted on the first mounting member is provided between the blocking cylinder 51 and the lifting cylinder 41. The blocking member is hinged to the hinge seat, with one end facing the blocking cylinder 51 and the other end facing the lifting cylinder 41. The push rod of the blocking cylinder 51 is also hinged to the end of the blocking member, and the retraction of the push rod of the blocking cylinder 51 can drive the other end of the blocking member to swing upward, thereby the swinging end of the blocking member can be used to block the fixture on the conveyor belt. Alternatively, a guide wheel can be installed at the end where the blocking component abuts against the fixture, thereby preventing mechanical scratches on the side of the fixture. The guide wheel can be a bearing. When the fixture needs to be released, the push rod of the blocking cylinder 51 extends, driving the guide wheel downward, and the blocking component lies flat, allowing the fixture to pass over it.

[0042] In some embodiments, the laser processing apparatus further includes a dust extraction mechanism 60, which includes a dust collection hood disposed above the first drive mechanism 30 and facing the lifting mechanism 40. The dust collection hood is used to collect the dust generated during marking. The flared end of the dust collection hood faces the fixture, and another port is connected to an external dust collector, which can suck up the dust through negative pressure.

[0043] In addition, the processing mechanism 20 also includes a height adjustment component 22 disposed on one side of the first conveying mechanism 10, and the processing module 21 is disposed on the movable end of the height adjustment component 22. In this embodiment, the height adjustment component includes a vertically mounted base, a lead screw rotatably mounted on the mounting base and kept vertical, a nut adapted to the lead screw and slidably connected to the mounting base, and a handwheel disposed on the upper end of the lead screw. The processing module 21 is connected to the nut, and by rotating the handwheel, the processing module 21 can be moved in the vertical direction to adjust the height of the processing module 21 so that the focal point of the laser beam is located on the upper surface of the workpiece.

[0044] In some embodiments, the laser processing apparatus further includes a second conveying mechanism 70 disposed below the first conveying mechanism 10, the conveying direction of the second conveying mechanism 70 being opposite to that of the first conveying mechanism 10; the laser processing apparatus also includes a fourth conveying mechanism for conveying the fixture from the first conveying mechanism 10 to the second conveying mechanism 70. In this embodiment, the second conveying mechanism 70 may also be two conveyor belts arranged side by side, located directly below the first conveying mechanism 10. The fourth conveying mechanism may be a robotic arm, which can be used to grasp an empty fixture and transfer it to the second conveying mechanism 70, so that the empty fixture flows back to the area below the beginning of the first conveying mechanism 10. Alternatively, another robotic arm can be disposed at the end of the second conveying mechanism 70 to lift the fixture back to the beginning of the first conveying mechanism 10, completing the fixture cycle. The fixture can have a workpiece inserted inside at the beginning of the first conveying mechanism 10, and the marked workpiece can be removed from the end of the first conveying mechanism 10. The assembly and removal of the workpiece can be performed by the aforementioned robotic arm, or by another robotic arm, or by manual operation.

[0045] In the above embodiments, sensors 34 can be respectively installed at the first, middle, and last sections of the first conveying mechanism 10 to sense the position of the fixture. Simultaneously, the aforementioned blocking mechanism 50 is configured on one side of each sensor 34, causing the fixture to be stopped at the first section, completing the workpiece placement process. The workpiece is then released to the middle section and stopped by the blocking mechanism 50 there, completing lifting, translation (first direction), and marking operations. The fixture is then lowered onto the first conveying mechanism 10 and released to the last section, completing the workpiece removal process.

[0046] This application also proposes a laser processing device, including two sets of laser processing devices; two first conveying mechanisms 10 arranged side by side; two first driving mechanisms 30 symmetrically arranged and positioned on the outer sides of the two first conveying mechanisms 10 facing away from each other; two processing mechanisms 20 arranged side by side above the first conveying mechanisms 10; and two processing modules 21 staggered and corresponding one-to-one with the two first conveying mechanisms 10. In this embodiment, by setting two sets of laser processing devices, the marking efficiency of this laser processing device can be further improved.

[0047] In this embodiment, the working principle of the laser processing device and equipment is as follows:

[0048] The first conveying mechanism 10 conveys the fixture along a first direction. The fixture, located at the beginning of the first conveying mechanism 10, completes the workpiece placement process. The workpiece is then conveyed to the middle section and detected by the sensor 34. The middle section's blocking mechanism 50 stops the workpiece, and the lifting end 42 of the lifting mechanism 40 engages with the fixture, lifting it away from the first conveying mechanism 10. Driven by the first driving mechanism 30, the workpiece moves along the first direction, allowing the upper processing module 21 to sequentially mark the workpieces in the fixture. After marking, the lifting end 42 of the lifting mechanism 40 descends, causing the fixture to fall back onto the first conveying mechanism 10, separating the lifting mechanism 40 from the fixture. The blocking mechanism 50 then releases the fixture. The fixture moves to the middle section of the first conveying mechanism 10, completing the workpiece removal process.

[0049] The laser processing apparatus and equipment of this application can achieve the following technical effects:

[0050] High-efficiency positioning and improved marking efficiency: The lifting mechanism 40 and the fixture employ one-time mechanical positioning, such as a pin-limiting hole structure or a countersunk groove connection, combined with the synchronous drive of the first drive mechanism 30. This allows the fixture to directly enter the dynamic marking process after detaching from the first conveying mechanism 10. Multiple workpieces on the fixture only need to be positioned once and can move as a whole with the fixture, eliminating the need for repeated positioning of each workpiece individually, significantly reducing waiting time and improving marking efficiency by over 30%. The upper and lower clamping design of the limiting component 35 and the lifting mechanism 40 effectively constrains the inertial displacement of the fixture, ensuring its stability during marking. Simultaneously, the through-hole of the limiting component 35 and the chamfered guide design of the workpiece further eliminate workpiece gaps, achieving precise positioning and improving marking accuracy.

[0051] Structural optimization and improved space utilization: The first conveying mechanism 10 adopts a parallel double conveyor belt design, with the lifting mechanism 40 and the blocking mechanism 50 integrated between the two conveyor belts. The jig detachment / reset is achieved through the vertical extension and retraction of the lifting cylinder 41, avoiding interference with the normal operation of the conveyor belts and reducing the equipment footprint. The first drive mechanism 30 is driven by an electric cylinder, which improves the positioning accuracy by 50% compared to traditional conveyor belts. Furthermore, the vertical distribution design of the first and second mounting components enables a modular layout of the lifting mechanism 40 and the limiting component 35, facilitating maintenance and adaptation to jigs of different specifications.

[0052] Enhanced dynamic marking and process compatibility: After the fixture is lifted, it is driven by the first drive mechanism 30 to move at a uniform speed along the first direction. Combined with the fixed installation of the processing module 21, continuous dynamic marking can be performed on the workpieces on the fixture, avoiding the mechanical impact of traditional start-stop marking and extending equipment life. The height adjustment component 22 supports vertical fine-tuning of the processing module 21, adapting to workpieces of different thicknesses and ensuring that the laser focus accurately falls on the workpiece surface, improving marking clarity.

[0053] Safety and environmental adaptability optimization: The material blocking mechanism 50 adopts guide wheel-type blocking components and cylinder drive to reduce mechanical wear on the contact surface of the fixture. Combined with the negative pressure dust collection hood of the dust extraction mechanism 60, it reduces the emission of marking fumes and improves the working environment. The third and fourth conveying mechanisms realize the closed-loop circulation of the fixture, and work with the robotic arm for automatic loading and unloading, reducing manual intervention and operational safety hazards, making it suitable for high-cycle automated production lines.

[0054] Scalability and cost-effectiveness: The dual-unit side-by-side design, with two laser processing devices working in tandem, doubles marking efficiency. The staggered layout avoids spatial conflicts, increasing overall equipment capacity by over 60%. Modular structural design, such as detachable limit plates and standardized interfaces for electric cylinder drives, reduces maintenance costs and shortens equipment modification and adaptation time, making it suitable for flexible production scenarios with multiple product varieties and small batches.

[0055] The above are only some or preferred embodiments of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
