Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment technology, and in particular to a fully automated fiber laser processing equipment. Background Technology

[0002] Ceramic materials are widely used in the manufacturing of electronic components, structural parts, and precision devices due to their high hardness, good wear resistance, and excellent insulation properties. Traditional mechanical cutting methods often result in chipping and cracking when processing ceramic materials, which not only affects product quality but also reduces production efficiency. With the rapid development of laser processing technology, fiber laser cutting has gradually become an important means of processing ceramic materials due to its advantages such as non-contact operation, high energy density, and high precision.

[0003] Despite this, existing fiber laser processing equipment still faces several pressing issues. First, the loading and unloading of workpieces largely rely on manual operation, resulting in low efficiency. Furthermore, manual placement or removal can easily lead to inaccurate workpiece positioning, affecting subsequent cutting accuracy and consistency. Second, existing equipment lacks automated detection and monitoring during loading and unloading, failing to effectively determine if a workpiece is already on the platform or whether the stacked quantity meets requirements, leading to uncertainties and management blind spots in the production process. Third, the cutting process generates a large amount of dust, which, if not promptly removed, can easily adhere to the workpiece surface, affecting cutting quality and potentially contaminating optical components, shortening the equipment's lifespan. Fourth, some equipment's processing platforms can only move along a single axis, unable to achieve precise movement in both horizontal and vertical directions, limiting the realization of complex processing paths and multi-station processing, severely restricting the equipment's flexibility and applicability.

[0004] Based on the above situation, it can be seen that existing fiber laser processing equipment has shortcomings in terms of automated loading and unloading, workpiece inspection and stacking management, dust control during the cutting process, and two-dimensional movement of the stage. Therefore, there is an urgent need to propose a fully automated fiber laser processing equipment that can achieve automatic loading and unloading, has workpiece inspection and stacking sensing functions, can perform synchronous dust removal during the cutting process, and can move precisely in the horizontal and vertical directions, in order to solve the problems existing in the current technology and improve processing efficiency and quality. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a fully automatic fiber laser processing equipment, which aims to solve the problems in the existing technology such as reliance on manual loading and unloading of workpieces, lack of workpiece inspection and stacking management, untimely dust cleaning during the cutting process, and limited movement of the processing platform.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a fully automatic fiber laser processing equipment, including a machine base, a sliding processing platform mounted on the machine base, a cutting and imaging device mounted on the machine base and located above the sliding processing platform, and an automatic loading and unloading device mounted on the machine base and located on one side of the sliding processing platform. The automatic loading and unloading device includes a loading platform, a unloading platform, a first guide rail column and a second guide rail column respectively mounted at the front and rear of the machine base, a transverse slide plate, and a first mechanical clamping assembly and a second mechanical clamping assembly respectively mounted below the transverse slide plate. The loading platform and the unloading platform are arranged side by side on the machine base. The first mechanical clamping assembly and the second mechanical clamping assembly are located above the loading platform and the unloading platform, respectively. One end of the transverse slide plate is slidably engaged with the guide rail on the first guide rail column and driven by a driving device, and the other end is slidably engaged with the guide rail on the second guide rail column.

[0007] Based on the above structural design, the beneficial effects of this utility model are as follows: By setting an automatic loading and unloading device on one side of the machine tool, and using a transverse slider to drive the first and second mechanical clamping components to move between the loading platform, the sliding processing platform, and the unloading platform, the automated transfer of workpieces is achieved, avoiding the inefficiency and positioning errors caused by manual loading and unloading, and significantly improving production efficiency and processing consistency. Both the loading platform and the unloading platform are equipped with product placement areas enclosed by limit plates, and are used in conjunction with sensors and stacking sensors. This not only detects whether there are workpieces in the placement area, but also judges the stacking status of the workpieces, thereby realizing intelligent monitoring of the loading and unloading status, which helps to ensure the production process. Continuity and stability are ensured by the laser cutting head and camera integrated into the cutting and imaging device. This allows for precise cutting of workpieces and real-time monitoring of the processing. A dust extraction device located below the device simultaneously cleans up dust generated during cutting, effectively preventing dust from affecting workpiece quality and optical components. This improves the cleanliness of the processing environment and cutting accuracy. The sliding processing stage employs a superimposed design of transverse and longitudinal guide rail components, enabling precise movement in both the transverse and longitudinal directions. This expands workpiece processing beyond a single direction, enhancing flexibility and adaptability, and meeting the needs of complex graphic cutting and multi-station processing.

[0008] Furthermore, both the first mechanical clamping assembly and the second mechanical clamping assembly include a mounting base disposed on the transverse sliding plate, a cylinder disposed on the mounting base, and a clamping assembly driven by the cylinder, the clamping assembly being used to clamp and release the workpiece.

[0009] Based on the above, the opening and closing action of the clamping component is realized by using a cylinder drive, thereby achieving stable clamping and reliable release during the workpiece handling process. The clamping component is fixed on the transverse slide by the mounting base, so that it can move with the transverse slide between the loading, processing and unloading positions, ensuring the accurate transfer of the workpiece between each process. This structure not only reduces manual intervention and improves the automation level of clamping and handling, but also effectively ensures the workpiece positioning accuracy and the stability of the processing process.

[0010] Furthermore, the clamping assembly includes a connecting block disposed at the cylinder output end, an adjusting frame evenly disposed at the four corners of the connecting block, and a gripper mounted on the adjusting frame. The gripper slides along the slide rail of the adjusting frame to adjust the spacing, thereby adapting to workpieces of different sizes.

[0011] Based on the above, the spacing between the grippers can be flexibly adjusted by the slide rail structure of the adjustment frame, making the clamping assembly suitable for clamping workpieces of various specifications. This significantly improves the compatibility and adaptability of the equipment. The sliding cooperation of the grippers within the adjustment frame not only ensures stable clamping of workpieces of different sizes, but also reduces the cost and operational complexity of frequently adjusting or replacing fixtures due to workpiece changes, thereby further improving processing efficiency and automation level.

[0012] Furthermore, both the loading platform and the unloading platform include a support platform, a lifting cylinder disposed below the support platform, several guide columns arranged circumferentially around the lifting cylinder, and several limiting plates arranged circumferentially on the support platform. The area enclosed by the several limiting plates forms a product placement area. A sensor is provided in the product placement area to detect whether there are products. A stacking sensor is provided at the upper end of the limiting plate to detect whether the products in the product placement area are fully stacked.

[0013] Based on the above, the lifting and adjustment of the workpiece is achieved by driving the bearing platform with a lifting electric cylinder, and the stability and positioning accuracy of the lifting process are ensured by the guide column. The product placement area enclosed by the limit plate can effectively limit the placement position of the workpiece and avoid deviation during handling or cutting. The setting of sensors and stacking sensors can not only detect the presence of products in real time, but also monitor the stacking status to avoid jamming or process disorder caused by excessive stacking, thereby improving the intelligence level of the loading and unloading process and the continuity and stability of the production process.

[0014] Furthermore, the cutting and shooting device includes a lifting motor, a cutter mounting bracket fixedly connected to the lifting motor, a laser cutter mounted on the cutter mounting bracket, a camera mounting bracket mounted on the cutter mounting bracket, and a camera mounted in the camera mounting bracket.

[0015] Based on the above, the vertical adjustment of the laser cutter mounting bracket, driven by a lifting motor, allows the laser cutter to be positioned appropriately according to the workpiece height and processing requirements, ensuring cutting accuracy and adaptability. A camera, mounted in a separate camera mounting bracket, can capture images of the workpiece before processing and feed these images back to the control system. After analysis, a cutting path is generated, which is then executed by the laser cutter. This structure not only achieves automatic identification and precise control of the cutting path but also effectively reduces manual intervention, improving the automation level of the equipment and the yield rate of finished products.

[0016] Furthermore, a dust collection device is also provided below the cutting and shooting device. The dust collection device includes a dust collection head and a connecting frame. One end of the connecting frame is fixedly installed at the lower end of the lifting motor, and the other end of the connecting frame is provided with a dust collection head. The dust collection head is connected to an external vacuum pump through a pipeline.

[0017] Based on the above, dust generated in the cutting area during laser cutting is simultaneously removed to prevent dust accumulation on the workpiece surface from affecting cutting quality. This also reduces dust contamination of optical components, thus ensuring cutting stability and processing accuracy. By fixing the dust suction head to the lower end of the lifting motor and moving it with it, the suction head is always kept close to the cutting position, improving the targeting and effectiveness of dust removal. This structure not only improves the cleanliness of the processing environment but also extends the service life of key equipment components, further enhancing the overall reliability and applicability of the equipment.

[0018] Furthermore, the sliding machining stage includes a machining stage, a transverse guide rail assembly, and a longitudinal guide rail assembly. The transverse guide rail assembly is mounted on the machine base, the longitudinal guide rail assembly is mounted on the transverse guide rail assembly, and the machining stage is mounted on the longitudinal guide rail assembly.

[0019] Based on the above, the superimposed structure of the transverse guide rail assembly and the longitudinal guide rail assembly enables the processing stage to move precisely in both the transverse and longitudinal directions, thus breaking through the limitation of existing equipment that can only move in a single axis. This structure not only improves the flexibility and diversity of the processing path, enabling the equipment to complete the cutting of complex graphics, but also realizes multi-station processing, further improving the applicability and production efficiency of the processing.

[0020] Furthermore, the transverse guide rail assembly includes a transverse linear guide rail and a transverse sliding seat. The longitudinal guide rail assembly is mounted on the transverse sliding seat. The longitudinal guide rail assembly includes a longitudinal linear guide rail and a longitudinal sliding seat. The processing stage slides with the longitudinal linear guide rail via the longitudinal sliding seat. The transverse guide rail assembly and the longitudinal guide rail assembly are driven by drive motors.

[0021] Based on the above, the cooperation of the transverse guide rail assembly and the longitudinal guide rail assembly enables the processing stage to move precisely in both the transverse and longitudinal directions. This allows the workpiece to be adjusted and positioned according to a preset trajectory during cutting. The drive motors control the transverse and longitudinal movements respectively, ensuring the independence and stability of the processing stage's operation and avoiding the limitations of single-axis structures in complex machining. This design not only improves the flexibility of the equipment and the diversity of processing paths, but also enhances cutting accuracy and production efficiency, making it suitable for high-precision machining of workpieces of different shapes and sizes.

[0022] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0026] The clamping assembly 52 includes a connecting block 520 disposed at the output end of the cylinder 51, an adjusting frame 521 evenly disposed at the four corners of the connecting block 520, and a gripper 522 mounted on the adjusting frame 521.

[0027] Both the loading platform 41 and the unloading platform 42 include a carrying platform 60, a lifting cylinder 61 disposed below the carrying platform 60, a plurality of guide columns 62 arranged circumferentially around the lifting cylinder 61, and a plurality of limiting plates 63 arranged circumferentially on the carrying platform 60. The area enclosed by the plurality of limiting plates 63 forms a product placement area. A sensor is provided in the product placement area to detect whether there are products. A stacking sensor is provided at the upper end of the limiting plate 63 to detect whether the products in the product placement area are fully stacked.

[0028] The cutting and shooting device 3 includes a lifting motor 31, a cutter mounting bracket 32 ​​fixedly connected to the lifting motor 31, a laser cutter 33 mounted on the cutter mounting bracket 32, a camera mounting bracket 34 mounted on the cutter mounting bracket 32, and a camera 35 mounted in the camera mounting bracket 34.

[0029] Below the cutting and shooting device 3, a dust collection device 7 is also provided. The dust collection device 7 includes a dust collection head 70 and a connecting frame 71. One end of the connecting frame 71 is fixedly installed at the lower end of the lifting motor 31, and the other end of the connecting frame 71 is provided with a dust collection head 70. The dust collection head 70 is connected to an external vacuum pump through a pipeline.

[0030] The sliding machining stage 2 includes a machining stage 20, a transverse guide rail assembly 21, and a longitudinal guide rail assembly 22. The transverse guide rail assembly 21 is mounted on the machine base 1, the longitudinal guide rail assembly 22 is mounted on the transverse guide rail assembly 21, and the machining stage 20 is mounted on the longitudinal guide rail assembly 22.

[0031] The transverse guide rail assembly 21 includes a transverse linear guide rail 23 and a transverse sliding seat 24. The longitudinal guide rail assembly 22 is mounted on the transverse sliding seat 24. The longitudinal guide rail assembly 22 includes a longitudinal linear guide rail 25 and a longitudinal sliding seat 26. The processing stage 20 slides with the longitudinal linear guide rail 25 through the longitudinal sliding seat 26. The transverse guide rail assembly 21 and the longitudinal guide rail assembly 22 are driven by drive motors.

[0032] In summary, the specific embodiments of this utility model are as follows: First, the workpiece to be processed is placed on the support platform 60 of the loading platform 41 by manual labor or upstream production process. The support platform 60 can move up and down by the drive of the lifting electric cylinder 61. With the help of the circumferentially set guide column 62, the lifting is stable and the positioning accuracy is guaranteed. When the workpiece is placed in the product placement area surrounded by the limit plate 63 of the loading platform 41, the sensor can detect whether the workpiece is in place. The stacking sensor can further determine whether the workpiece is stacked to the predetermined height, thereby realizing automatic monitoring of the loading status.

[0033] Next, under the action of the drive motor, the horizontal slider 44 slides along the guide rails on the first guide rail column 43 and the second guide rail column 47, driving the first mechanical clamping assembly 45 installed below it to move above the loading platform 41. The cylinder 51 drives the clamping claw 52 to move, and after the workpiece is reliably clamped, the horizontal slider 44 continues to move. The first mechanical clamping assembly 45 transports the workpiece to the position of the sliding processing platform 2, and accurately places the workpiece on the processing platform 20 through the release action.

[0034] During the processing stage, the sliding processing stage 2, through the cooperation of the transverse guide rail assembly 21 and the longitudinal guide rail assembly 22, enables the processing stage 20 to move precisely in the transverse and longitudinal directions, allowing the workpiece to be positioned and adjusted according to the preset path. The cutting and shooting device 3 adjusts its height under the drive of the lifting motor 31. The camera 35 first takes a picture of the workpiece to be processed and feeds the image information back to the control system. After analysis, the cutting path of the workpiece is obtained and then transmitted to the laser cutter 33. The laser cutter 33 cuts the workpiece according to the preset path. The dust generated during the cutting process is simultaneously removed by the dust suction device 7 set below the cutting and shooting device 3. The dust suction head 70 is always close to the processing area, effectively ensuring the cleanliness of the cutting environment and the reliability of the optical components.

[0035] Finally, during the unloading stage, the horizontal slider 44 moves to the position of the sliding processing stage 2 under the drive of the drive motor, which drives the second mechanical clamping assembly 46 to clamp the processed workpiece and transfer it to the bearing platform 60 of the unloading stage 42. The unloading stage 42 is also equipped with sensors and stacking sensors to detect whether the processed workpieces are stacked in place and whether the predetermined quantity has been reached, thereby realizing automated unloading and stacking management.

[0036] Through the above process, this utility model realizes fully automated operation from loading, handling, processing to unloading. It not only avoids the inefficiency and positioning error caused by manual loading and unloading, but also ensures the stability and cleanliness of the processing process through the cooperation of detection and dust collection structure. At the same time, the bidirectional movement of the sliding processing platform 2 improves the flexibility of the processing path and the adaptability to complex graphics, thereby significantly improving the processing efficiency of the workpiece and the quality of the product.

[0037] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
