Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an automatic sheet metal loading and unloading mechanism and its laser cutting machine. Background Technology

[0002] In laser cutting equipment applications, the efficiency of sheet material loading and unloading directly affects the overall processing cycle and production efficiency of the machine. Although existing laser cutting machines are generally equipped with automated cutting control systems, efficiency bottlenecks still exist in the sheet material loading and unloading process. The common method is to use forklifts or manual labor to move entire stacks of sheets to the cutting machine, and then use suction cup robots or clamping devices to load them one by one. This type of operation is highly dependent on manual intervention, labor-intensive, and requires frequent adjustments during the gripping process, resulting in excessively long loading times for individual sheets, making it difficult to meet the demands of high-cycle, continuous cutting.

[0003] Meanwhile, due to the lack of efficient coordination with the loading and unloading mechanisms, the sheet material transfer process often relies on forklifts or manual labor to frequently travel between the material storage area and the cutting station. This increases energy consumption, slows down the handling cycle, and further reduces overall production efficiency. Especially in some production lines equipped with multiple laser cutting machines, the existing loading and unloading mechanisms are limited by gripping accuracy and motion control logic, often making it difficult to complete the rapid switching between multiple machine positions in a timely manner, resulting in the equipment utilization rate not being fully realized. Utility Model Content

[0004] In order to overcome the defects of the prior art, the present invention provides an automatic loading and unloading mechanism for sheet metal and its laser cutting machine, which can effectively meet the working needs of multiple laser cutting machines, reduce material transfer links, reduce energy consumption, and improve the coordination efficiency between the material system and the cutting station.

[0005] The technical solution adopted by this utility model to solve its problem is: An automatic board loading and unloading mechanism includes: A frame, on which a load-bearing beam is provided, and a first guide rail and a rack are provided along the length direction on the load-bearing beam; The slide block is slidably connected to the load-bearing beam and slides in cooperation with the first guide rail via the first slider. A first drive motor is mounted on the slide block, and its output end is provided with a gear that meshes with the rack to drive the slide block to reciprocate along the length of the load-bearing beam; A support bracket is slidably connected to the slide block. The support bracket is equipped with a gripping assembly for loading and unloading materials. The gripping assembly includes a claw assembly for gripping the sheet metal and a suction cup.

[0006] Furthermore, the slide block is provided with a second slider, and the bearing bracket is provided with a second guide rail at a corresponding position that slides with the second slider; The slide block is also provided with a driving component, the output end of which is connected to the support bracket and is used to drive the support bracket to move up and down in the vertical direction.

[0007] Furthermore, a second drive motor is provided on the support bracket, and the output shaft of the second drive motor is provided with a transmission chain; The gripper assembly includes a first gripper and a second gripper, the first gripper and the second gripper being slidably connected to both ends of the support bracket and both being connected to the transmission chain; When the second drive motor drives the transmission chain to move, it causes the first gripper and the second gripper to move closer or further apart, so as to clamp or release the plate.

[0008] Furthermore, the first gripper includes a first gripper frame and a plurality of first insert rods disposed on the first gripper frame, the plurality of first insert rods being arranged at intervals along the length of the first gripper frame; The second gripper includes a second gripper frame and a plurality of second insert rods disposed on the second gripper frame, the plurality of second insert rods being arranged at intervals along the length of the second gripper frame.

[0009] Furthermore, one end of the support bracket is provided with a third slider, and the other end is provided with a fourth slider; The first gripper holder is provided with a third guide rail that slides in cooperation with the third slider, and the second gripper holder is provided with a fourth guide rail that slides in cooperation with the fourth slider.

[0010] Furthermore, it also includes a workpiece carrying platform, of which two are provided, one for carrying unprocessed sheet metal and the other for carrying processed sheet metal.

[0011] Furthermore, the bottom of the workpiece platform is provided with multiple casters for movement.

[0012] Furthermore, multiple suction cups are provided, and the multiple suction cups are arranged at intervals at the bottom of the support bracket.

[0013] Furthermore, the frame includes a plurality of support columns spaced apart along the length of the load-bearing beam.

[0014] A laser cutting machine includes the aforementioned automatic loading and unloading mechanism for sheet metal.

[0015] In summary, this utility model has the following technical effects: 1. This utility model relates to an automatic sheet metal loading and unloading mechanism and its laser cutting machine. By installing a guide rail and rack-and-pinion structure on the support beam of the frame, and equipping the slide with a first drive motor, the reciprocating movement of the slide along the support beam is achieved through the meshing of the gear and rack at the motor's output end. This ensures stable horizontal movement of the support frame, avoiding the problem of inaccurate position control during traditional manual or forklift handling. Simultaneously, the support frame integrates suction cups and gripper assemblies, allowing for flexible selection of suction or clamping methods based on the different sizes and materials of the sheet metal. This not only improves the reliability of sheet metal gripping but also shortens the loading time for a single sheet, enabling rapid clamping and release, and significantly improving loading and unloading efficiency.

[0016] 2. The automatic loading and unloading mechanism for sheet metal and its laser cutting machine of this utility model adopts a sliding connection between the support bracket and the slide and is controlled by a drive component, which can realize the lifting action of the support bracket, so that the gripping component can be flexibly switched between different heights.

It solves the problems of low sheet metal loading efficiency and strong reliance on manual labor in the prior art, and also improves the overall continuity and stability of automated processing. It has the advantages of reasonable structure, high efficiency of operation and wide applicability. Attached Figure Description

[0020] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] like Figure 1-3 The automatic sheet metal loading and unloading mechanism and its laser cutting machine shown include a frame 1, a slide 2, a first drive motor 21, and a support bracket 3. The frame 1 is equipped with a support beam 11, which has a first guide rail 111 and a rack 112 along its length. The slide 2 is slidably connected to the support beam 11 and slides with the first guide rail 111 via a first slider 22. The first drive motor 21 is mounted on the slide 2, and its output end has a gear 211 that meshes with the rack 112 to drive the slide 2 to reciprocate along the length of the support beam 11, thereby achieving large-stroke horizontal conveying and ensuring the coverage of the loading and unloading actions. The support bracket 3 is slidably connected to the slide 2 and is equipped with a gripping component for loading and unloading. The gripping component includes a clamping jaw assembly and a suction cup 35 for gripping the sheet metal, which can select vacuum adsorption or mechanical clamping under different working conditions, improving the stability and adaptability of sheet metal handling.

[0024] This utility model's automatic sheet metal loading and unloading mechanism can effectively meet the needs of multiple laser cutting machines, avoiding frequent material transfers between storage and cutting stations, reducing energy consumption and manual intervention in handling equipment. Simultaneously, the automated handling method shortens material changeover cycles, improves the continuous processing capacity of the cutting machines, and significantly enhances overall production efficiency.

[0025] Furthermore, the slide block 2 is equipped with a second slider 24, and the support bracket 3 is equipped with a second guide rail 36 at a corresponding position that slides and engages with the second slider 24. The slide block 2 is also equipped with a driving component 23, the output end of which is connected to the support bracket 3 to drive the support bracket 3 to move up and down in the vertical direction, thereby realizing the vertical up and down movement of the sheet metal. This design not only ensures the height controllability of the sheet metal during handling, but also avoids collisions or scratches caused by inaccurate manual operation, thus improving processing accuracy and safety.

[0026] Furthermore, a second drive motor 31 is mounted on the support bracket 3, and a transmission chain 32 is mounted on the output shaft of the second drive motor 31. The gripper assembly includes a first gripper and a second gripper, which are slidably connected to both ends of the support bracket 3 and are both connected to the transmission chain 32. When the second drive motor 31 drives the transmission chain 32, it can cause the two grippers to move synchronously closer or further apart, realizing rapid clamping or release of the plate. This bidirectional synchronous clamping method not only improves the stability of the plate positioning but also effectively avoids plate deformation caused by uneven clamping.

[0027] Furthermore, the first gripper includes a first gripper frame 4 and multiple first insert rods 41 disposed thereon, the multiple first insert rods 41 being spaced apart along the length direction of the first gripper frame 4; the second gripper includes a second gripper frame 5 and multiple second insert rods 51 disposed thereon, the multiple second insert rods 51 being spaced apart along the length direction of the second gripper frame 5. The spaced arrangement of the insert rods enables uniform force support for plates of different sizes, enhancing the reliability of the gripping.

[0028] Specifically, the first gripper frame 4 is connected to the transmission chain 32 via the first connecting plate 43, and the second gripper frame 5 is connected to the transmission chain 32 via the second connecting plate 53, with the two arranged vertically offset. When the transmission chain 32 moves in a certain direction, it can drive the two gripper frames to move closer or further apart, thereby clamping or releasing the plate. This offset transmission structure not only simplifies the mechanical transmission process but also makes the gripper movement smoother and extends the service life of the mechanism.

[0029] Furthermore, one end of the support bracket 3 is provided with a third slider 33, and the other end is provided with a fourth slider 34; the first gripper frame 4 is provided with a third guide rail 42 that slides in cooperation with the third slider 33, and the second gripper frame 5 is provided with a fourth guide rail 52 that slides in cooperation with the fourth slider 34. Through the cooperation of multiple sliders and guide rails, the gripper can maintain a straight running trajectory during the driving process, avoiding swaying due to uneven force and ensuring clamping accuracy.

[0030] Furthermore, it also includes a workpiece carrier 6, of which there are two, one for holding unprocessed sheet metal and the other for holding processed sheet metal. This partitioned design ensures that the loading and unloading processes do not interfere with each other, thereby reducing waiting time at the cutting station and improving the overall processing continuity of the machine.

[0031] Furthermore, the bottom of the workpiece platform 6 is equipped with multiple casters 61 for support and overall movement and position adjustment. This design allows the workpiece platform 6 to be flexibly moved in or out when unprocessed sheet metal needs to be added or processed sheet metal removed, significantly improving operational convenience and equipment adaptability, reducing the intensity of manual handling, and ensuring the safety and efficiency of sheet metal transfer. In other embodiments, drive motors can be installed on the casters 61 to achieve active drive control of the casters 61, enabling the workpiece platform 6 to automatically complete displacement operations, further improving the system's automation level and overall collaborative efficiency.

[0032] Furthermore, multiple suction cups 35 are provided and spaced apart at the bottom of the support bracket 3, which can evenly distribute the suction force when picking up the board, preventing large-sized boards from warping or slipping, and improving the stability of board handling.

[0033] Furthermore, the frame 1 includes multiple support columns 12 spaced apart along the length of the load-bearing beam 11 to enhance the overall rigidity and stability of the load-bearing beam 11 and ensure that the large-format panels do not vibrate or shift during handling.

[0034] In addition, this utility model also provides a laser cutting machine, including the aforementioned automatic sheet metal loading and unloading mechanism. During operation, the mechanism and the laser cutting machine 7 can be uniformly controlled via a controller. During the loading process, the first drive motor 21 drives the slide 2 to move above the workpiece platform 6 of the unprocessed sheet material, the second drive motor 31 drives the transmission chain 32 to move the two grippers away, and at the same time the drive component 23 drives the support bracket 3 to descend, so that the suction cup 35 contacts the sheet material and adsorbs the top layer of sheet material; then the drive component 23 rises, and the two grippers move closer again to strengthen the fixation of the sheet material; then, the first drive motor 21 drives the slide 2 to send the sheet material to the loading area of ​​the laser cutting machine 7 to realize automatic loading.

[0035] During the unloading process, the process is executed in reverse, ultimately transferring the processed sheet metal to the workpiece platform 6 that carries the processed sheet metal. Through the above coordinated actions, the machine can continuously complete the automatic loading and unloading of sheet metal, greatly reducing manual intervention and improving the level of production automation and overall processing efficiency.

[0036] In summary, the automatic sheet metal loading and unloading mechanism and its laser cutting machine of this utility model, by setting a guide rail and rack 112 cooperating structure on the bearing beam 11 of the frame 1, and configuring a first drive motor 21 on the slide 2, utilizes the meshing of the gear 211 at the output end of the motor with the rack 112 to realize the reciprocating movement of the slide 2 along the bearing beam 11, thereby ensuring the stable movement of the bearing support 3 in the horizontal direction and avoiding the problem of difficult precise position control during traditional manual or forklift handling. At the same time, the bearing support 3 integrates a suction cup 35 and a gripper assembly, which can flexibly select the adsorption or clamping method according to the different sizes and materials of the sheet metal. This not only improves the reliability of sheet metal gripping, but also shortens the loading time of a single sheet metal, realizes rapid clamping and release, and significantly improves loading and unloading efficiency.

[0037] The present invention relates to an automatic loading and unloading mechanism for sheet metal and its laser cutting machine. The support bracket 3 and the slide 2 are slidably connected and controlled by a drive component 23, which can realize the lifting and lowering action of the support bracket 3. This allows the gripping component to flexibly switch between different heights, effectively meeting the working needs of multiple laser cutting machines 7, reducing material transfer links, lowering energy consumption, and improving the coordination efficiency between the material system and the cutting station.

[0038] This utility model relates to an automatic sheet metal loading and unloading mechanism and its laser cutting machine. Under the coordinated action of the slide block 2 drive and the gripping component, it can achieve rapid switching between multiple laser cutting machines, avoiding switching delays caused by insufficient gripping accuracy or complex control logic. This improves equipment utilization and production cycle time, solves the problems of low sheet metal loading efficiency and high manual dependence in the prior art, and also enhances the overall continuity and stability of automated processing. It has the advantages of reasonable structure, high efficiency of operation and wide applicability.
