Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a double-station laser cutting machine. Background Art

[0002] Laser cutting machine is a device that uses laser beam for cutting. It has become a common industrial equipment due to its precision and efficiency.

[0003] At present, laser cutting machines are generally divided into two types: 1. Continuous cutting machine, which has a high degree of automation and high continuous operation efficiency, but its cost is high and its precision control requirements are very high, resulting in high production and use costs; 2. Intermittent cutting machine, which performs cutting operations when stationary. After cutting, the laser head stops working and starts cutting again after the material is transported away and new material is delivered. The cutting head of this type of cutting machine is frequently idle, which will greatly reduce the cutting efficiency;

[0004] In addition, the laser cutting machine uses a high-power laser beam to cut materials. During the cutting process, the laser beam heats the material to a high temperature state, causing it to melt, evaporate or gasify, thereby achieving the purpose of cutting. In this process, high-temperature debris will be generated. The high-temperature debris may adhere to or scatter on the conveyor table. Although the staff will clean the conveyor table regularly, due to the continuity of the operation of the production equipment, the debris will still accumulate during the use of the conveyor table, resulting in the workpiece being unable to be placed flat when being transported on the conveyor table, affecting the accuracy of the cutting.

[0005] Therefore, a double-station laser cutting machine is proposed to solve the above problems. Summary of the invention

[0012] Preferably, a connecting frame is fixedly connected to the bottom of the adjustment plate, an L-shaped stop block is fixedly connected to the bottom of the connecting frame, one side of the lower end of the L-shaped stop block is set as an inclined surface, and a push rod is fixedly connected to one side of the rotating shaft.

[0013] Preferably, the adjustment adaptation mechanism includes a support block, the support block is fixedly connected to one side of the adjustment plate, an adjustment screw is threadedly connected to one side of the support block, a sliding push block is slidably connected to one side of the adjustment plate, the adjustment screw is rotatably connected to the sliding push block, and a connecting plug is fixedly connected to one side of the sliding push block.

[0014] Preferably, one side of the adjustment plate is symmetrically rotatably connected to a torsion spring shaft, an outer surface of the torsion spring shaft is fixedly connected to a linkage clamping plate, and an opposite side of the linkage clamping plate is equidistantly fixedly connected to a locking ball.

[0015] Preferably, a groove is provided on one side of the U-shaped slideway, the locking ball is engaged with the groove, a mounting groove is provided on one side of the mounting plate, a guide column is symmetrically fixedly connected in the mounting groove, and a synchronization rod is slidably connected to the outer surface of the guide column.

[0016] Preferably, both ends of the synchronization rod are provided with slots, the connecting blocks are plugged into the slots, the sliding push block is arranged in an arc shape near the linkage clamping plate, and both ends of the synchronization rod pass through the U-shaped slideway.

[0017] Compared with the prior art, the present invention provides a dual-station laser cutting machine, which has the following beneficial effects:

[0018] 1. Through the setting of the material anti-tilt mechanism, the symmetrically arranged connecting frame and L-shaped block rotate toward the material direction at the same time, which can push the material, so that the material will move to the middle of the two connecting frames after being pushed by the two sides. When the cutting platform conveys materials due to parts wear or system errors, the conveying position will have too much or too little displacement. Through the pushing of the symmetrically arranged connecting frame, the material can be centered. At the same time, through the setting of the inclined surface at the lower end of the L-shaped block, the lower end of the L-shaped block contacts the top of the cutting platform when rotating and is inserted into the lower part of the material. Then, through the cooperation between the extrusion force generated by the rotation of the L-shaped block and the inclined surface, the bottom of the material is located at the uppermost end of the inclined surface, and the two sides of the material are aligned with the connecting frame. The connecting frame is in contact with the L-shaped stop block, and then the material is separated from the cutting platform, which can reduce the impact of cutting debris generated on the top of the cutting platform, avoid the uneven placement of the material due to the presence of cutting debris on the top of the cutting platform, and improve the accuracy of material cutting. At the same time, the material is located at the center between the connecting frame and the L-shaped stop block through clamping and pushing by the connecting frame and the L-shaped stop block, which improves the positioning effect with the laser cutting head. At the same time, the material can be clamped and supported by the connecting frame and the L-shaped stop block to improve the stability of the material during cutting, prevent the material from shaking during cutting due to external force, and further improve the accuracy of material cutting and the quality after cutting.

[0019] In addition, through the effect of the ladder frame, when one side of the ladder frame pushes the symmetrically arranged push rod, the lateral surface of the ladder first contacts and pushes the horizontal push rod, and after the push rod rotates to a certain angle, the inclined surface of the ladder frame contacts and pushes the inclined push rod. This contact method provides a smooth pushing process with a relatively large contact area, thereby dispersing the thrust, reducing the impact and vibration when the push rod rotates, reducing wear, extending the service life of the ladder frame and the push rod, and improving the stability during pushing.

[0020] 2. By adjusting the setting of the adaptation mechanism, the adjustment plate slides on the U-shaped slideway to adjust the distance between the adjustment plates when clamping the material, so that the material anti-tilt mechanism can fix and prevent skew operations on materials of different specifications, thereby improving the application range of the material anti-tilt mechanism. At the same time, through the cooperation of the sliding push block, the torsion spring shaft and the linkage clamping plate, when the adjusting screw is rotated, the fixing or disengagement work of the connecting plug block and the synchronous rod, and the fixing or disengagement work of the card ball and the groove can be completed at the same time, saving additional operations and improving the efficiency of adjusting the adjustment plate. At the same time, through the setting of the connecting plug block and the synchronous rod, when the adjustment plate is adjusted, the synchronous rod can synchronously adjust the adjustment plates on both sides by inserting the connecting plug block, so that the adjustment plates on both sides slide synchronously for distance adjustment, which not only improves the adjustment efficiency, but also avoids the situation that the sliding distance of the adjustment plates on both sides are inconsistent when sliding separately through synchronous sliding, thereby improving the accuracy of adjusting the adjustment plate and ensuring the subsequent centering effect of the connecting frame and the L-shaped block on the material.

[0021] 3. The dual-station laser cutting machine adopts a dual-station design and is modified on the basis of the original laser cutting machine. The modification cost is low, which makes up for the defect of the cutting head of the traditional intermittent cutting machine that frequently stops working, so that the cutting head can work uninterruptedly, greatly improving the working efficiency. The cutting range of the cutting area can be flexibly adjusted according to the width of the material to meet the cutting needs of coatings of different widths, and has a wide range of applications.

[0041] The material enters the leveling machine 2 after being released by the coiling machine 1, and then enters the cutting platform 3 after being leveled by the leveling machine 2. The support bars 8 arranged in parallel on the cutting platform 3 can be driven by a servo motor to move relative to or toward each other, so as to accurately adjust the support width of the cutting platform 3. It should be supplemented that the relative or toward movement of the support bars 8 on the cutting platform 3 can be driven by any driving form such as cylinder drive, ball screw drive, etc., and its structure and working principle are prior art and will not be described in detail here.

[0042] The two workstations can work alternately or independently. The system can set a processing quantity limit or set the coil length to ensure the safety and integrity of the cycle processing. When the system is working alternately, when the material in any processing area is used up, the system will terminate the cycle and issue a relevant alarm. The user can manually change to the single processing mode to continue processing.

[0043] The material anti-tilt mechanism includes a mounting plate 3011, which is fixedly connected to the top of the cutting platform 3. An inverted L-shaped rod 3012 is symmetrically fixedly connected to one side of the four-axis motion platform 7. The inverted L-shaped rod 3012 is fixed to the outer shell of the horizontal sliding member of the four-axis motion platform 7. The inverted L-shaped rod 3012 is driven to slide horizontally reciprocatingly by the four-axis motion platform 7, and when the laser cutting head 6 is driven to rise and fall, it will not affect the inverted L-shaped rod 3012. A ladder frame 3013 is fixedly connected to the bottom of the inverted L-shaped rod 3012. One side of the mounting plate 3011 is symmetrically rotatably connected to the rotating shaft 30 14.

[0044] In the prior art, continuous cutting machines are highly automated and have high continuous operation efficiency. However, they are expensive and have very high requirements for precision control, resulting in high production and use costs. Intermittent cutting machines are used for cutting when they are stationary. After cutting, the laser head stops working and waits for the material to be transported away and new material to be delivered before starting cutting. The cutting head of this type of cutting machine is frequently idle, which greatly reduces the cutting efficiency. During the cutting process, the laser beam heats the material to a high temperature, causing it to melt, evaporate or gasify, thereby achieving the purpose of cutting. During this process, high-temperature slag is generated, which may adhere to or scatter on the conveyor table, resulting in the workpiece being transported on the conveyor table without any The method of placing the material flat affects the precision of cutting. Compared with the prior art, the implementation of this embodiment, the double-station laser cutting machine adopts a double-station design, which is modified on the basis of the original laser cutting machine. The modification cost is low, which makes up for the defect that the cutting head of the traditional intermittent cutting machine frequently stops working, so that the cutting head can work uninterruptedly, greatly improving the working efficiency. The cutting range of the cutting area can be flexibly adjusted according to the material width to meet the cutting requirements of coatings of different widths. It has a wide range of applications. By making the material separate from the contact with the cutting platform 3, the influence of the cutting debris generated on the top of the cutting platform 3 can be reduced, avoiding the phenomenon that the material is placed unevenly due to the presence of cutting debris on the top of the cutting platform 3, and improving the precision of material cutting.

[0045] For further examples, please refer to Figures 1 to 9 As shown:

[0046] The adjustment and adaptation mechanism includes a support block 3111, which is fixedly connected to one side of the adjustment plate 3018, an adjustment screw 3112 is threadedly connected to one side of the support block 3111, a sliding push block 3113 is slidably connected to one side of the adjustment plate 3018, the adjustment screw 3112 is rotatably connected to the sliding push block 3113, a connecting plug 3114 is fixedly connected to one side of the sliding push block 3113, a torsion spring shaft 3115 is symmetrically rotatably connected to one side of the adjustment plate 3018, and a linkage clamp 311 is fixedly connected to the outer surface of the torsion spring shaft 3115 6. A card ball 3117 is equidistantly fixedly connected to the opposite side of the linkage clamping plate 3116, a groove 3118 is provided on one side of the U-shaped slide 3017, and the card ball 3117 is engaged with the groove 3118. A mounting groove is provided on one side of the mounting plate 3011, and guide columns 3119 are symmetrically fixedly connected in the mounting groove. A synchronization rod 3120 is slidably connected to the outer surface of the guide column 3119. Slots are provided at both ends of the synchronization rod 3120, and the connecting block 3114 is plugged into the slot. The sliding push block 3113 is set to an arc shape near the side of the linkage clamping plate 3116.

[0047] Wherein: both ends of the synchronization rod 3120 pass through the middle of the U-shaped slide 3017, so that when the rotating plate 3015 drives the U-shaped slide 3017 to rotate, the synchronization rod 3120 will not block the U-shaped slide 3017.

[0048] The implementation of this embodiment enables the material anti-tilt mechanism to fix and prevent materials of different specifications, thereby improving the application scope of the material anti-tilt mechanism, improving the efficiency of adjusting the adjustment plate 3018, improving the accuracy of adjusting the adjustment plate 3018, and ensuring the subsequent centering effect of the connecting frame 3019 and the L-shaped block 3020 on the material.

[0049] Everything in the above example works like this:

[0050] In the initial state, the torsion spring shaft 3115 is in a torsion state, and the end of the linkage clamping plate 3116 close to the support block 3111 abuts against the sliding push block 3113, and at this time, the locking ball 3117 is locked with the groove 3118;

[0051] During operation: the material to be cut is placed on the coiler 1, and is slowly transferred to the cutting platform 3 after being leveled and pulled by the leveler 2. When one group of materials reaches the designated cutting position, the laser cutting head 6 starts cutting. While the laser cutting head 6 is cutting, another group of materials arranged in parallel reaches the designated position and waits for cutting. After the first group of materials is cut, the laser cutting head 6 directly moves horizontally to the top of the other group of materials for cutting. The cut materials are transferred to the conveyor line 4 at the tail end and taken away for storage. At the same time, the incoming materials that have not yet been cut are positioned again and wait for cutting, which can ensure the continuous operation of the laser cutting head 6.

[0052] The dual-station laser cutting machine adopts a dual-station design and is modified on the basis of the original laser cutting machine. The modification cost is low and it makes up for the defect of the cutting head of the traditional intermittent cutting machine that frequently stops working, so that the cutting head can work uninterruptedly, greatly improving the working efficiency. The cutting range of the cutting area can be flexibly adjusted according to the width of the material to meet the cutting needs of coatings of different widths, and has a wide range of applications.

[0053] The following is the working process of the material anti-tilt mechanism:

[0054] When the four-axis motion platform 7 drives the laser cutting head 6 to move back and forth horizontally and continuously cuts the material on the cutting platform 3, the four-axis motion platform 7 moves horizontally. Since the inverted L-shaped rod 3012 and the ladder frame 3013 are symmetrically fixedly connected to the outer side of the shell of the four-axis motion platform 7, when it moves, the ladder frame 3013 can be moved closer to the push rod 3021. Since the rotating shaft 3014 is rotatably connected to the mounting plate 3011, the push rod 3021 is fixedly connected to the rotating shaft 3014, so that One side of the ladder frame 3013 pushes the symmetrical push rod 3021 to rotate with the rotating shaft 3014, and the rotation angle is 90°. At the same time, under the push of the ladder frame 3013, the symmetrical push rod 3021 drives the symmetrical rotating shaft 3014 to rotate 90°, and then drives the rotating plate 3015, the U-shaped slide 3017 and the adjusting plate 3018 to rotate 90° through the rotating shaft 3014, so that the connecting frame 3019 and the L-shaped block 3020 rotate in the direction of conveying the material above the cutting platform 3;

[0055] By simultaneously rotating the symmetrically arranged connecting frame 3019 and the L-shaped stop block 3020 in the direction of the material, a pushing effect can be exerted on the material, so that after being pushed by the two sides, the material will move to the middle of the two connecting frames 3019. If the cutting platform 3 conveys material at too many or too few conveying positions due to parts wear or system errors, the symmetrically arranged connecting frame 3019 can push the material to the center. At the same time, through the setting of the inclined surface at the lower end of the L-shaped stop block 3020, the lower end of the L-shaped stop block 3020 contacts the top of the cutting platform 3 during rotation and inserts into the lower part of the material. Then, through the cooperation between the extrusion force generated by the rotation of the L-shaped stop block 3020 and the inclined surface, the symmetrically arranged L-shaped stop block 3020 inclined surface can generate an upward force on the bottom of the material when pushing the material, thereby causing the material to move upward and break away from the contact with the top of the cutting platform 3. Finally, under the guidance of the inclined surface, the bottom of the material is located at the uppermost end of the inclined surface. At this time, The material clamped by the connecting frame 3019 and the L-shaped block 3020 can be cut by the laser cutting head 6, and the two sides of the material are in contact with the connecting frame 3019 and the L-shaped block 3020, so that the material is separated from the contact with the cutting platform 3, and the influence of the cutting debris generated on the top of the cutting platform 3 can be reduced, thereby avoiding the uneven placement of the material due to the cutting debris on the top of the cutting platform 3, and improving the accuracy of material cutting. At the same time, the material is clamped and pushed by the connecting frame 3019 and the L-shaped block 3020, so that the material is located at the center between the connecting frame 3019 and the L-shaped block 3020, thereby improving the positioning effect with the laser cutting head 6. At the same time, the clamping support of the connecting frame 3019 and the L-shaped block 3020 can improve the stability of the material during cutting, and prevent the material from shaking during cutting due to external force, thereby further improving the accuracy of material cutting and the quality after cutting.

[0056] In addition, through the effect of the trapezoidal shape of the ladder frame 3013, when one side of the ladder frame 3013 pushes the symmetrically arranged push rod 3021, the lateral surface of the trapezoid first contacts and pushes the horizontal push rod 3021, and after the push rod 3021 rotates to a certain angle, the inclined surface of the ladder frame 3013 contacts and pushes the inclined push rod 3021. This contact method provides a smooth pushing process with a relatively large contact area, thereby dispersing the thrust, reducing the impact and vibration of the push rod 3021 when it rotates, reducing wear, and extending the service life of the ladder frame 3013 and the push rod 3021, while improving the stability during pushing.

[0057] And through the cooperation of the ladder frame 3013, the push rod 3021, the rotating shaft 3014, the rotating plate 3015 and the connecting frame 3019, when the four-axis motion platform 7 drives the laser cutting head 6 to approach the material, the push of the ladder frame 3013 will cause the connecting frame 3019 to rotate and clamp and suspend the material. When the material is cut, the laser cutting head 6 is away from the cut material, that is, when the four-axis motion platform 7 drives the laser cutting head 6 to approach the material on the other side, the connecting frame 3019 can cancel the push of the push rod 3021 on this side. At this time, under the torsional force of the reset torsion spring 3016, the adjusting plate 3018 can be driven to rotate and reset, so that it is no longer located above the cutting platform 3, which ensures The centering and suspended leveling operations of the material will not affect the normal conveying of the material. Compared with the prior art, the entire process is completed by utilizing the power of the four-axis motion platform 7, avoiding the installation and use of an additional driving source, saving energy, and improving the utilization rate of the mechanical kinetic energy of the four-axis motion platform 7. The connecting frame 3019 and the L-shaped block 3020 are both vertically arranged, and the bottom inclined surface of the L-shaped block 3020 is arranged, so that the debris generated by the cutting is not easy to stay and adhere to the side of the connecting frame 3019 and the L-shaped block 3020 that clamps and squeezes the material, saving the time for cleaning the connecting frame 3019 and the L-shaped block 3020, and at the same time improving the reliability of the connecting frame 3019 and the L-shaped block 3020 when in use.

[0058] Please refer to the above working process Figures 1 to 9 .

[0059] The following is the working process of the adjustment and adaptation mechanism:

[0060] When laser cutting is performed on materials, when materials of different specifications need to be cut, the length of the materials changes, because the distance between the two connecting frames 3019 and the L-shaped stop block 3020 needs to be adjusted by adjusting the adaption mechanism;

[0061] When adjusting, the adjusting screws 3112 on both sides can be rotated respectively. Since the adjusting screws 3112 are threadedly connected to the supporting block 3111 and are rotatably connected to the sliding push block 3113, and the sliding push block 3113 is slidably connected to the adjusting plate 3018, when the adjusting screws 3112 are rotated, the adjusting screws 3112 can push the sliding push block 3113 toward the U-shaped slideway 3017, and then push the connecting plug blocks 3114 at both ends to be inserted into the slots at both ends of the synchronization rod 3120. At the same time, when the sliding push block 3113 slides toward the card ball 3117, the sliding push block 3113 cancels the thrust on the linkage splint 3116. At this time, the torsion spring shaft 3115 enters the normal state from the torsion state, thereby driving the linkage splint 3116 to rotate clockwise at the end close to the groove 3118. Figure 8 As shown, the ball 3117 is disengaged from the groove 3118. At this time, since the connecting blocks 3114 on both sides are inserted into the slots of the synchronization rod 3120, the synchronization rod 3120 can be directly pulled or pushed, so that the synchronization rod 3120 drives the adjustment plates 3018 on both sides to slide through the connecting blocks 3114 and the sliding push blocks 3113, so that the adjustment plates 3018 slide on the U-shaped slide 3017 and complete the adjustment. After the adjustment is completed, the adjusting screw 3112 can be rotated in the opposite direction, and the sliding push blocks 3113 can be driven to slide in the direction away from the U-shaped slide 3017, so that the connecting blocks 3114 are disengaged from the synchronization rod. 3120, and at the same time, the arc surface of the sliding push block 3113 squeezes one end of the linkage clamping plate 3116, so that the linkage clamping plate 3116 is close to the groove 3118 and rotates toward the groove 3118, so that the locking ball 3117 is re-engaged with the groove 3118. At this time, under the thrust of the sliding push block 3113 on one end of the linkage clamping plate 3116, a mutual abutment force is formed between the locking ball 3117 and the groove 3118, thereby completing the fixation of the adjustment plate 3018, and because the connecting plug block 3114 is separated from the synchronization rod 3120, when the adjustment plate 3018 rotates, the synchronization rod 3120 will not interfere with the adjustment plate 3018;

[0062] The adjustment plates 3018 slide on the U-shaped slideways 3017 to adjust the distance between the adjustment plates 3018 when clamping the materials, so that the material anti-tilt mechanism can fix and prevent skew operations on materials of different specifications, thereby improving the application range of the material anti-tilt mechanism. At the same time, through the cooperation of the sliding push block 3113, the torsion spring shaft 3115 and the linkage clamping plate 3116, when the adjusting screw 3112 is rotated, the connection block 3114 and the synchronization rod 3120 can be fixed or disengaged, and the card ball 3117 and the groove 3118 can be fixed or disengaged at the same time, thereby saving extra operations, simplifying the operation process, reducing the operation steps and the required tools, reducing the operation difficulty and error rate, and improving the efficiency of adjusting the adjustment plates 3018. The setting of the block 3114 and the synchronization rod 3120 allows the synchronization rod 3120 to synchronously adjust the adjustment plates 3018 on both sides by inserting the connecting plug block 3114 when the adjustment plate 3018 is adjusted, so that the adjustment plates 3018 on both sides slide synchronously to adjust the distance, which not only improves the efficiency of adjustment, but also avoids the situation that the sliding distances of the adjustment plates 3018 on both sides are inconsistent when sliding separately through synchronous sliding, thereby improving the adjustment accuracy of the adjustment plates 3018, and also avoids shaking or instability caused by inconsistent sliding of the adjustment plates 3018 on both sides, thereby ensuring the safety of materials during processing or transportation, and also ensuring the subsequent centering effect of the connecting frame 3019 and the L-shaped block 3020 on the materials.
