Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to a laser device with automatic flipping capability. Background Technology

[0002] Laser processing technologies, such as laser marking, engraving, cutting, and welding, are widely used in modern manufacturing due to their advantages such as high precision, high efficiency, non-contact processing, and wide applicability. In industries such as 3C electronics, automotive parts, and precision instruments, laser processing is frequently required on multiple surfaces or even entire three-dimensional curved surfaces of products.

[0003] Currently, most common laser equipment on the market uses: Fixed workpiece type: The workpiece is fixedly mounted on a platform, and the laser head moves along the X, Y, and Z axes to complete the machining. This method is effective for machining planar or simple three-dimensional contours. However, when machining the sides or bottom of the workpiece, the limited range of motion and working angle of the laser head often creates blind spots. To solve this problem, the operator must stop the machine midway and manually flip or reclamp the workpiece. This not only significantly reduces production efficiency and increases labor intensity, but also easily introduces positioning errors during multiple clamping operations, resulting in the inability to guarantee the relative positional accuracy between different machined surfaces, seriously affecting the yield rate. Summary of the Invention

[0004] The purpose of this invention is to address the problem in existing technologies where processing dead corners requires manual workpiece flipping and stopping midway, and to provide a laser equipment with automatic flipping capability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser device with automatic flipping capability, comprising: Machine tool; A laser processing mechanism, mounted on the machine base, is used to generate and output a laser beam to process the product to be processed; A workpiece clamping and flipping mechanism is set on the machine base to support and fix the product to be processed, and can adjust the spatial posture of the product during processing; The control system is electrically connected to the laser processing mechanism and the workpiece clamping and flipping mechanism, and is used to control the coordinated movement of the two. The workpiece clamping and flipping mechanism includes: The lifting module is vertically installed on the machine platform; A hollow rotating platform is installed at the output end of the lifting module to drive the product to rotate around a vertical axis; The product fixture is installed on the hollow rotating platform and is used to clamp the product to be processed.

[0006] Furthermore, the laser processing mechanism includes Lasers are used to generate the laser beams required for processing. A height adjustment mechanism is used to adjust the working height of the laser's beam-emitting focal point relative to the workpiece; A cold water tank, connected to the laser via a fluid pipeline, is used for circulating cooling of the laser.

[0007] Furthermore, the control system includes An industrial control computer, running control software, is used to process processing graphic data and generate control commands; The PLC control system operation screen is connected to the industrial control computer and is used to receive control commands and directly control the movement of the lifting module and the hollow rotating platform.

[0008] Furthermore, the product fixture includes Several limiting blocks are arranged around the outer periphery of the workpiece on the upper surface of the hollow rotating platform to radially limit the workpiece. A clamping drive device is mounted on a hollow rotating platform. Its output end acts on the workpiece to press and fix the workpiece onto the upper surface of the hollow rotating platform.

[0009] Furthermore, the product includes Mounting base; A drive motor is mounted on the mounting base; The camera body is connected to the output shaft of the drive motor and is driven by the drive motor to adjust the shooting position.

[0010] The beneficial effects of this utility model after adopting the above technical solution are as follows: Through the workpiece clamping and flipping mechanism (combining a lifting module and a hollow rotating platform), the workpiece can flexibly adjust its spatial posture during processing. This allows the laser beam to irradiate different surfaces of the workpiece at the optimal angle, including the sides, slopes, and even some recessed areas.

[0011] Overcoming the limitations of single-angle machining: Traditional equipment has a fixed workpiece, which can only process the upper surface or requires multiple manual flipping. This equipment enables multi-face machining with a single clamping, making it particularly suitable for machining workpieces with complex three-dimensional contours (such as products with cameras).

[0018] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a laser processing device with automatic rotation. This solution relates to an advanced automatic rotation laser processing device, mainly used for laser processing of precision workpieces. Through a highly integrated mechanical structure and intelligent control system 4, this device achieves automatic adjustment of the workpiece posture and precise coordination of laser processing during the processing.

[0019] The equipment mainly includes the following core components: Machine 1: Serves as the basic support platform for the entire equipment.

[0020] Laser processing mechanism 2: Installed on machine base 1, responsible for generating and outputting laser beams for processing.

[0021] Workpiece clamping and flipping mechanism 3: Set on the machine base 1, it is used to carry and fix the product 5 to be processed, and can adjust its spatial posture as needed.

[0022] Control system 4: Electrically connected to the two aforementioned mechanisms, responsible for coordinating and directing their movements.

[0023] II. Detailed Explanation of the Workpiece Clamping and Tilting Mechanism This mechanism is the core of the automatic workpiece flipping system, and its structure is as follows: Lifting module 31: Vertically mounted on machine base 1, providing vertical freedom of movement.

[0024] Hollow rotating platform 32: Installed at the output end of lifting module 31, it can be driven to rotate precisely around a vertical axis.

[0025] Product fixture 33: Mounted on the hollow rotary platform 32, specifically used for clamping and fixing the product 5 to be processed. Its specific components include: Several limiting blocks 331: arranged around the outer periphery of the workpiece to radially position the workpiece.

[0026] Clamping drive device 332: Its output end acts on the workpiece, firmly pressing the workpiece onto the upper surface of the hollow rotating platform 32.

[0027] Through the combined movement of the lifting module 31 and the hollow rotating platform 32, the mechanism can flexibly adjust the spatial position and angle of the clamped workpiece.

[0028] III. Detailed Explanation of Laser Processing Mechanism 2 This organization is responsible for performing laser processing tasks, including: Laser 21: The core light-emitting component that generates the laser beam required for processing.

[0029] Height adjustment mechanism 22: used to finely adjust the working distance between the laser beam focus of laser 21 and the workpiece surface to ensure optimal processing results.

[0030] Cold water tank 23: It is connected to the laser 21 through a fluid pipeline to form a circulating cooling system to ensure the stable operation of the laser 21 during long-term operation.

[0031] IV. Detailed Explanation of Control System 4 Control system 4 is the "brain" of the equipment, enabling automated processing: Industrial Control Computer 41: Runs professional control software, responsible for processing complex machining graphic data and generating corresponding control commands.

[0032] PLC control system operation panel 42: It is connected to the industrial control computer 41 and, after receiving instructions, directly drives and controls the lifting module 31 and the hollow rotating platform 32 in the workpiece clamping and flipping mechanism 3 to perform precise actions.

[0033] V. Description of Products to be Processed The target product 5 processed by this equipment is a camera module with adjustable shooting direction, and its typical structure includes: Mounting base 51: Provides a fixed foundation.

[0034] Drive motor 52: mounted on mounting base 51.

[0035] Camera body 53: connected to the output shaft of drive motor 52, and can be driven by drive motor 52 to change its shooting position.

[0036] The first stage of the working principle of this utility model: preparation and clamping Program preparation The operator imports the 3D model or processing graphic data of the product to be processed 5 into the control software of the industrial control computer 41.

[0037] The software can automatically or manually plan the laser processing path and the synchronized workpiece flipping trajectory. For example, the program will set up to process surface A first, then the workpiece needs to be flipped by a certain degree to process surface B, and then raised and rotated by a certain amount to process surface C.

[0038] All these motion commands and processing parameters (such as laser power and speed) are integrated into a complete processing program.

[0039] Workpiece clamping The product to be processed 5 (such as a camera module) is placed in the product fixture 33 on the hollow rotating platform 32.

[0040] The limiting blocks 331 of the product fixture 33 will ensure the basic radial positioning of the workpiece.

[0041] Start the clamping drive device 332 (such as a cylinder or electric pressure arm) to firmly press the workpiece onto the fixture base surface, ensuring that it will not loosen during subsequent flipping and high-speed movement.

[0042] Phase Two: Automated Processing Start processing: The operator presses the start button on the PLC control system control panel 42. The control system 4 then begins executing the pre-programmed machining program.

[0043] Coordinating movement and processing: The entire process is no longer the traditional "laser head moving alone", but rather the linkage between the "laser head" and the "workpiece clamping and flipping mechanism 3".

[0044] Machining the front side: The program first controls the lifting module 31 to rise, sending the workpiece to a suitable working height. Then, the laser 21 emits a laser beam, which processes the upper surface (front side) of the workpiece according to a predetermined path. At this time, the hollow rotary platform 32 may also rotate slowly to assist in completing the machining of the annular area on the upper surface.

[0045] Flipping and processing the side: After the front processing is completed, the laser 21 will temporarily shut off or move to a safe position. Next, the control system 4 commands the hollow rotary platform 32 to rotate precisely by an angle (e.g., 90°) to align the side of the workpiece with the laser head. Simultaneously, the lifting module 31 may fine-tune its height to ensure the laser focus falls on the correct position on the side. Once adjusted, the laser 21 emits light again to process the side.

[0046] Complex posture adjustment: For more complex curved surfaces or structures (such as the spherical surface of the camera body 53), the lifting module 31 and the hollow rotating platform 32 will perform continuous, interpolated coordinated movements. This means that the workpiece is dynamically adjusting its posture during processing, always keeping the point being processed at the optimal processing angle with the laser beam, thereby achieving three-dimensional engraving or marking.

[0047] Process monitoring and cooling: Throughout the entire processing, the cold water tank 23 continuously circulates and cools the laser 21 to ensure stable power and long lifespan.

[0048] The PLC monitors the status of each actuator in real time to ensure precise motion.

[0049] Phase 3: Processing Completion and Material Unloading Reset and release: When the program detects that all processing steps have been completed, the laser 21 stops emitting light.

[0050] The workpiece clamping and flipping mechanism 3 will move the workpiece to an initial posture that is convenient for unloading (e.g., rotate back to the 0° position, and the lifting module 31 descends to the low position).

[0051] The clamping drive device 332 is released, thus releasing the workpiece from its fixation.

[0052] Material preparation: Operators or accompanying automated robotic arms remove the finished product 5.

[0053] Then, the next product to be processed can be clamped immediately, and a new cycle can begin, greatly reducing equipment waiting time.

[0054] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
