Description

Technical Field

[0001] The present invention relates to the field of laser automatic cutting and processing equipment, and particularly to a workpiece batch processing device, an automatic processing system and a batch processing method. Background Art

[0002] Laser cutting machines are widely used in the cutting and processing of metal, non-metal plates and profiles, and have the advantages of high processing efficiency, high processing accuracy and wide adaptability.

[0003] In the automotive manufacturing industry, automobiles require a large number of metal parts, and these metal parts are required to have low weight and high bending strength requirements. The raw materials for producing these metal parts are high-strength steel plates. The processing method is generally to heat the high-strength plate and then use a punching machine to form it, and then perform fine secondary processing, such as punching holes, slotting and cutting off redundant edges, to ensure processing efficiency and processing accuracy. Now, it is necessary to automatically and continuously mass-produce automotive parts, and requirements for product accuracy are also put forward. General three-axis laser cutting machines have low use costs, but can only process workpieces in a plane, while multi-axis laser cutting machines can perform complex processing, but have high use costs.

[0004] A patent with the publication number CN206869318U discloses a loading and unloading device for a laser cutting machine, including a frame and a laser cutting machine. The exchange workbench of the laser cutting machine is arranged in the frame. A loading and unloading robot is connected to the upper side of the frame. In the width direction, a double-layer loading and unloading mechanism is also arranged in the frame. The loading and unloading robot includes a crossbeam moving mechanism that can move back and forth along the frame. A fork material mechanism that can be opened and closed and lifted is connected to the crossbeam moving mechanism. A material suction mechanism that can be lifted is connected to the fork material mechanism. The material suction mechanism includes a material suction frame, and a number of fixed suction cups for sucking workpieces are arranged on the material suction frame. Before the material suction mechanism descends, the material suction mechanism is above the fork material mechanism. The loading and unloading device of this laser cutting machine has a large volume for the loading and unloading mechanism, and cannot cooperate with the action of the laser cutting head to adjust the direction of the workpiece on the workbench after loading, and can only be used for plane processing. The loading mechanism needs to move horizontally on the track, resulting in poor continuity of loading. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a workpiece batch processing device, which solves the problems of low batch processing efficiency of laser cutting machines and the inability of the workbench to cooperate with the laser cutting head for movement.

[0012] The tumbling device further includes a dragging mechanism, which is slidably connected to the carriage along the direction of the first rotating ring axis. The dragging mechanism includes a hook and a first cylinder. The hook is arranged at one end of the first cylinder, and the other end of the first cylinder is connected to the first rotating ring, and is used to push the material-carrying platform for loading and unloading materials.

[0013] The material-carrying platform includes a tray and a plurality of limit buckles, which are arranged on the tray at intervals in sequence, and are used to fix the workpieces to be processed, and can load multiple workpieces at one time, improving the processing efficiency of the workpieces.

[0041] 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 of the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] Embodiment 1

[0043] As Figures 1-8 shown, a workpiece batch processing device includes a laser cutting machine 1, a tumbling device 2 and a material-carrying platform 3. The tumbling device 2 is rotatably connected to the laser cutting machine 1 and can rotate circumferentially around an axis parallel to the ground to expand the processing range of the laser cutting machine 1. The material-carrying platform 3 is detachably and slidably connected to the tumbling device 2. The tumbling device 2 includes a first swivel ring 21 and a slide carriage 22. The first swivel ring 21 is rotatably connected to the laser cutting machine 1, and one end of the slide carriage 22 is arranged on the end face of the first swivel ring 21 along the axis direction of the first swivel ring 21.

[0044] Preferably, the laser cutting machine 1 includes a machine body 11 and a first driving device 13. The first driving device 13 is arranged on the machine body 11. The first driving device 13 includes a reduction motor 131, a transmission shaft 132 and a transmission sprocket 133. The reduction motor 131 is arranged on the side wall of the machine body 11. The transmission shaft 132 is connected to the reduction motor 131. The transmission sprocket 133 is arranged at one end of the machine body 11. The first rotating ring 21 includes an outer ring tooth 211 and a rolling groove 212. The outer ring tooth 211 is arranged on the outer wall of the first rotating ring 21. The rolling groove 212 is arranged on the outer wall of the first rotating ring 21 and is arranged side by side with the outer ring tooth 211. The transmission shaft 132 drives the transmission sprocket 133 to rotate through a chain. The transmission sprocket 133 drives the first rotating ring 21 to rotate through a chain. The laser cutting machine 1 can be selected according to the complexity of the workpiece 5 to be processed. If the workpiece 5 only has an inclined plane around one axis, a three-axis laser cutting machine that moves in a plane can be used for processing. If the workpiece 5 is more complex, a multi-axis laser cutting machine can be selected for processing to reduce the equipment cost.

[0045] Furthermore, the tumbling device 2 further includes a second rotating ring 25. The second rotating ring 25 is connected to the other end of the carriage 22. The first rotating ring 21, the carriage 22 and the second rotating ring 25 form a cylindrical structure. The first rotating ring 21 and the second rotating ring 25 are connected together by the carriage 22 and are simultaneously driven by the first driving device 13 on the laser cutting machine 1. Driving both ends simultaneously increases the rotation of the tumbling device 2, and the consistency of turning the workpiece 5 is good. The cylindrical tumbling device 2 has high strength and is not easily deformed, improving the precision of laser cutting and processing.

[0046] Preferably, the carriage 22 includes a cross beam 221, a first pulley 222 and a second pulley 223. One end of the cross beam 221 is connected to the first rotating ring 21, and the other end is connected to the second rotating ring 25. The first pulley 222 is arranged on the side wall of the cross beam 221. The second pulley 223 is arranged on the other side wall of the cross beam 221 adjacent to the first pulley 222. The cross beam 221 is a C-shaped cross-section beam, and the opening of the cross beam 221 faces the axis of the first rotating ring 21. The material loading platform 3 slides in the cross beam 221, and the cross beam 221 plays a role of sliding limit. The first pulley 222 is installed on the side wall of the cross beam 221, and its wheel surface protrudes from the side wall of the cross beam 221 and extends into the C-shaped groove. The side wall of the material loading platform 3 contacts the first pulley 222, playing a guiding role. The second pulley 223 is installed at the bottom of the cross beam 221, and the wheel surface of the second pulley 223 protrudes from the bottom surface of the cross beam 221 and extends into the C-shaped groove of the cross beam 221, directly contacting the material loading platform 3, used to support the material loading platform 3 and reduce the friction when the material loading platform 3 moves.

[0047] Preferably, the laser cutting machine 1 further includes a plurality of supporting wheels 14 and a positioner 23. The plurality of supporting wheels 14 are respectively arranged in pairs at both ends of the bed 11. The plurality of supporting wheels 14 are in contact with the outer rings of the first rotating ring 21 and the second rotating ring 25, and are used to support the rolling device 2 to rotate and be limited on the bed 11. The positioner 23 is arranged on the carriage 22 and is used to position the material-carrying platform 3 on the carriage 22. The paired supporting wheels 14 are in rolling cooperation with the rolling grooves 212 on the first rotating ring 21 to form a centerless rotation structure, leaving space for the workpiece 5 to be processed, and also playing a role in guiding the rolling device 2 and preventing the rolling device 2 from disengaging from the bed 11. The positioner 23 is an electromagnetic buckle, which can be locked when the load-carrying platform 3 moves in place, and can maintain a flat clamping force even in the case of power failure.

[0048] Preferably, the rolling device 2 further includes a dragging mechanism 24. The dragging mechanism 24 is slidably connected to the carriage 22 along the axial direction of the first rotating ring 21. The dragging mechanism 24 includes a hook 241 and a first cylinder 242. The first cylinder 242 is a double-acting cylinder, which can drive the hook 241 to reciprocate. The hook 241 is arranged at one end of the first cylinder 242, and the other end of the first cylinder 242 is connected to the first rotating ring 21, and is used to drag the material-carrying platform 3 to move in the feeding channel. The dragging mechanism 24 cooperates with the manipulator 4 to continuously move the workpiece 5 under the laser cutting head 12 for processing.

[0049] Preferably, the material-carrying platform 3 includes a tray 31 and a plurality of limit buckles 32. The plurality of limit buckles 32 are sequentially arranged at intervals on the tray 31 and are used to fix the workpiece 5 to be processed. The tray 31 is a frame structure, and a groove matching the shape of the workpiece 5 is provided at the end of the tray 31 for accurately positioning the workpiece 5. The limit buckles 32 are electromagnetic buckles, which can act quickly and still maintain a clamping force after power failure to prevent the workpiece 5 on the tray 31 from falling off. The limit buckles 32 are installed in pairs near the edge of the tray 31, and the paired limit buckles 32 act simultaneously. A plurality of pairs of limit buckles 32 are installed along the length direction of the tray 31 and can act separately, and are used to clamp a plurality of workpieces 5 at one time on the material-carrying platform 3. The distance between adjacent pairs of limit buckles 32 is equal, which is convenient for the laser cutting machine 1 to perform processing and positioning.

[0050] Preferably, a loading guide frame 7 is further provided on the workpiece batch processing device. The loading guide frame 7 can be docked with the tumbling device 2 to form a feeding channel. The material loading platform 3 enters the carriage 22 through the feeding channel. The loading guide frame 7 is used to supply materials to the workpiece batch processing device from the outside. By extending the length of the feeding channel through the loading guide frame 7, it is convenient for the manipulator 4 to load materials or dock with other material substitution devices for loading. One material loading platform 3 can be stored in the loading guide frame 7. After the workpieces 5 in one material loading platform 3 are processed, the material loading platform 3 stored in the loading guide frame 7 can directly slide under the laser cutting head 12, with seamless connection between the two, shortening the loading time and improving the efficiency of continuous batch processing.

[0051] An automatic processing system includes a manipulator 4, a workpiece batch processing device, and a magazine 6. The manipulator 4 is installed on the side of the workpiece batch processing device, and the magazine 6 is arranged around the manipulator 4. One end of the loading guide frame 7 faces the carriage 22 directly, and the other end faces the magazine 6. The manipulator 4 can load and unload workpieces in batches for multiple workpieces in sequence to maximize the utilization rate of the equipment. In addition, the manipulator 4, the workpiece batch processing device, and the magazine 6 are taken as a unit, and multiple units can be arranged in a workshop to complete the processing of the workpieces 5. The number of arranged units can be flexibly determined by the required production capacity, making the installation flexibility of this automatic processing system high.

[0052] A workpiece batch processing method is implemented by a batch processing device, specifically including the following steps:

[0053] S1. Loading: The workpieces 5 are sequentially placed on the material loading platform 3, and the material loading platform 3 positions and locks the workpieces 5.

[0054] S2. Feeding: The material loading platform 3 slides into the carriage 22 from one end of the tumbling device 2, and the tumbling device 2 positions and locks the material loading platform 3.

[0055] S3. Tumble processing: After processing, the laser cutting machine 1 performs cutting processing on the workpieces 5, and the tumbling device 2 rotates by a certain angle to process the inclined surfaces of the workpieces 5, so that the surface of the workpieces 5 is always facing the laser cutting machine 1 directly, improving the processing accuracy.

[0056] S4. Unloading: The tumbling device 2 releases the fixation of the processed material loading platform 3 and pushes the material loading platform 3 out of the carriage 22.

[0057] S5. Steps S1 - S4 are cyclically executed to complete the batch processing of the workpieces 5.

[0058] The more specific processing process is as follows:

[0059] The tumbling device 2 rotates to align the carriage 22 with the loading guide frame 7. The loading platform 3 moves to the outer end of the loading guide frame 7 and waits for loading. The manipulator 4 sequentially picks up the workpieces 5 from the magazine 6 and places them equidistantly on the loading platform 3. The limit buckles 32 on the loading platform 3 act to clamp the workpieces 5 from both ends. After the workpieces 5 are clamped, the dragging mechanism 24 under the carriage 22 moves forward and hooks the frame of the loading platform 3. The dragging mechanism 24 retracts to drag the loading platform 3 along the feeding channel formed by the loading guide frame 7 and the carriage 22 to move under the laser cutting head 12. At this time, the positioner 23 moves downward to clamp the loading platform 3. The laser cutting machine 1 starts to perform cutting processing on the workpieces 5 in sequence. During processing, the tumbling device 2 rotates around the horizontal axis so that the inclined surface on the workpiece 5 can be perpendicular to the laser line emitted by the laser cutting head 12, enabling accurate processing of the workpiece 5. After batch processing of the workpieces 5 is completed, they can be dragged out of the loading guide frame 7 again by the dragging mechanism 24. Then, the manipulator 4 picks up the processed workpieces 5 and places them in the finished product magazine 6. The manipulator 4 then picks up the unprocessed workpieces 5 and places them on the loading platform 3. Repeating this process can complete the batch continuous processing of the workpieces 5.

[0060] Embodiment 2

[0061] As Figure 9 shown, the same features as in Embodiment 1 will not be described in detail. The differences are as follows: The automatic workpiece processing system includes a conveyor line 8 and an AGV cart 9. The conveyor line 8 is arranged close to the loading guide frame 7 of the workpiece batch processing device. The RGV cart is arranged at the other end of the workpiece batch processing device. There are two manipulators 4 on this automatic processing system, which are respectively used for loading and unloading. Multiple workpiece batch processing devices are distributed on one side of the same conveyor line 8. Loading by the conveyor line 8 is faster. Through the cooperation of the two manipulators 4 and the RGV cart 9 for unloading, after the workpieces 5 on the loading platform 3 are processed, loading and processing can be carried out again, further improving the efficiency of the entire automatic processing system.

[0062] This workpiece batch processing device can also be used for laser batch welding.
