Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, and in particular to a blanking mechanism of laser cutting equipment. Background Art

[0002] Laser cutting technology has become a core processing method in metal processing, sheet metal manufacturing, automotive parts, aerospace and other fields with its advantages of high precision, high speed and high flexibility. With the rapid development of industrial automation, the processing efficiency of laser cutting equipment continues to improve. A single cut can complete batch processing of multiple workpieces. The separation, transfer and collection of workpieces and waste after cutting have become key links affecting overall production efficiency and workpiece quality. The unloading mechanism is an important part of laser cutting equipment. First, it safely removes the cut workpiece from the nail bed to avoid the workpiece being retained and affecting the next round of cutting. Second, it effectively separates the workpiece from the waste generated by cutting to ensure that the workpiece surface is free of damage and impurities, meeting the quality requirements of subsequent processing.

[0003] In the existing technology, traditional manual unloading relies on operators to manually carry workpieces, which is labor-intensive and difficult to match the high-speed processing rhythm of laser cutting equipment. This results in long equipment standby times, affecting processing efficiency. When unloading with semi-automatic methods, the workpiece and waste are not completely separated. After cutting, the workpiece and waste are often connected due to partial uncut parts or burrs, forming a jam. When unloading, the two are easily pushed onto the conveyor belt together, resulting in the mixing of workpieces and waste. Subsequent manual sorting is required, which increases additional working hours and reduces overall processing efficiency. How to invent a unloading mechanism for laser cutting equipment to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1, refer to Figures 1-9 A material unloading mechanism of a laser cutting device includes a cutting table 1 and a vibration assembly 2 and a cutting assembly 3 arranged on the cutting table 1. A material unloading chute 11 and a debris chute 12 are respectively formed on the outer walls of both sides of the cutting table 1. A screen plate 17 and a cleaning plate 18 are respectively installed on the inner wall of the cutting table 1. A conveying assembly is installed on the cutting table 1, and the conveying assembly includes an ear plate 13, a motor 14, a conveying wheel 15, a transmission belt 16, and a nail plate 161. The cutting assembly 3 includes a slide rail 31, a controller 32, a slide 33 and a cutting head 34. The two slide rails 31 are respectively installed on both sides of the cutting table 1; The vibration assembly 2 includes a sprocket 21 , an adjusting wheel 212 , a chain 22 and a toothed belt 23 .

[0023] Furthermore, the opening of the feed chute 11 is higher than the opening of the debris chute 12, and the outer wall of the cutting table 1 near the feed chute 11 is fixedly connected to the collection frame 111, and the outer wall of the cutting table 1 near the debris chute 12 is fixedly connected to the debris frame 121. The sieve plate 17 is installed above the cleaning plate 18, and the sieve plate 17 and the cleaning plate 18 are both inclined. The high end of the cleaning plate 18 is close to the lower end of the sieve plate 17, and the two ends of the slide 33 slide on the slide rail 31, and the cutting head 34 is moved on the slide 33. The controller 32 slides, and the driving components of the cutting head 34 and the slide 33 are electrically connected. Four ear plates 13 are arranged in pairs at both ends of the cutting table 1. The motor 14 is installed on the side wall of an ear plate 13. The two ends of the conveying wheel 15 are rotatably connected to the inner wall of the ear plate 13 of the same group. The output end of the motor 14 is fixedly connected to one end of the conveying wheel 15. Several nail plates 161 are equidistantly fixedly connected to the side walls of the two transmission belts 16. The inner side walls at both ends of the transmission belt 16 are transmission-connected to the conveying wheel 15.

[0024] It should be noted that: when cutting, the plate is placed on the cutting table 1 above several nail plates 161, the cutting path is set in advance by the controller 32, and then the workpiece is cut by the movement of the slide 33 and the cutting head 34 (the working process of the cutting component 3 is the existing technology), the spacing between the nail plates 161 outside the transmission belt 16 is set according to the size of the workpiece to be cut, if the plate needs to be cut as a whole to obtain the workpiece, the part separated from the plate during the cutting process is waste, and at this time the waste falls through the gap between the nail plates 161 under the action of gravity onto the screen plate 17 below, and the screen plate 17 The reason for the inclined design is to enable the waste to slide into the collecting frame 111 on one side under the action of gravity. After that, the motor 14 is started to drive the conveyor wheel 15 to operate, thereby driving the outer transmission belt 16 to move, thereby driving the nail plate 161 on the transmission belt 16 to lift the plate and move it until the plate passes one end of the cutting table 1 and falls off for collection. At this time, the plate can be unloaded, so that the workpiece and waste after cutting can be collected separately, and the operation of manually unloading the workpiece and waste is abandoned, thereby improving the efficiency of unloading and further improving the overall efficiency of workpiece processing. If the plate is a base material and workpieces of different shapes need to be cut from it, the cut plate is waste material and is transported to one end of the cutting table 1 for recycling through the nail plate 161, and the required workpiece falls onto the screen plate 17 through the gap between the nail plates 161. At the same time, the debris generated during the cutting process falls onto the cleaning plate 18 below through the sieve holes on the screen plate 17. Then, the workpiece slides into the collecting frame 111 on one side, and the debris falls onto the cleaning plate 18 below, and slides into the debris frame 121 on the other side under the action of gravity, thereby achieving separation between the workpiece and the debris, avoiding the mixed collection of the debris and the workpiece, resulting in During the subsequent transfer process, the surface of the workpiece is scratched due to friction and collision, thereby affecting the overall quality. At the same time, the separated debris can be collected and recovered. In the subsequent processing process, it can be processed by melting to achieve reuse, thereby reducing the cost of raw materials. In addition, the screen plate 17 and the cleaning plate 18 are made of wear-resistant steel. This material has a good wear-resistant effect and can avoid the wear of the surface caused by long-term impact of debris and workpieces, ensuring the smoothness of the surface and improving the sliding effect of the workpiece. At the same time, the surface is polished to reduce the friction between the workpiece and the debris, further improving the falling collection effect of the workpiece.

[0025] For example 2, please refer to Figures 8-11 , based on the first embodiment, in order to avoid the gap between the cut workpiece and the waste being too small to cause the jamming and affect the separation; Furthermore, one end side wall of the sieve plate 17 is fixedly connected to a rotating shaft 171 rotatably connected to the inner wall of the cutting table 1, and the inner wall below the end of the cutting table 1 close to the high end of the sieve plate 17 is fixedly connected to two fixed plates 19, and a spring 191 is fixedly connected to the upper end of the fixed plate 19. The upper end side wall of the spring 191 contacts the bottom side of the sieve plate 17, and a number of sprockets 21 are equidistantly arranged on the outer walls of both sides of the cutting table 1. One end of the sprocket 21 is rotatably connected to the inner wall of the cutting table 1, and the sprockets 21 on the same side rotate synchronously through the chain 22 One end of one of the lateral sprockets 21 is fixedly connected to the second toothed pulley 211, and one end of a conveying wheel 15 close to the second toothed pulley 211 is fixedly connected to the first toothed pulley 151. The first toothed pulley 151 and the second toothed pulley 211 are connected via a toothed belt 23. The adjusting wheel 212 is fixedly connected to one end of the sprocket 21 close to the inner wall of the cutting table 1. The adjusting wheel 212 is an elliptical cylinder. A reciprocating screw rod 41 is fixedly connected between the two sets of mirrored adjusting wheels 212 close to the two ends of the cutting table 1.

[0026] It should be noted that: in the process of unloading the workpiece or waste material above the nail plate 161 by driving the conveyor wheel 15 after cutting, the sprocket 21 on one side of the cutting table 1 is synchronously driven by the toothed belt wheel and the toothed belt 23 to rotate. At the same time, several sprockets 21 on the same side are rotated under the action of the chain 22, and the sprocket 21 on the other side is rotated at the same time under the action of the reciprocating screw rod 41, thereby realizing the rotation of multiple sprockets 21 on both sides. The transmission belt 16 is made of polyurethane material and has extremely high elasticity. During the rotation of the sprocket 21, the adjusting wheel 212 at one end of the inner wall of the cutting table 1 rotates synchronously. The adjusting wheel 212 is elliptical in design. When its long side wall contacts the transmission belt 16, the transmission belt 16 is in the initial state. The upper nail plate 161 can be effectively supported by the adjusting wheel 212 to avoid the transmission belt 16 below the nail plate 161 from being squeezed downward when the workpiece is heavy, thereby improving the safety during the conveying process. During the rotation of the adjusting wheel 212, when the long side wall of the elliptical adjusting wheel 212 contacts the transmission belt 16, the transmission belt 16 remains horizontal at this time. When the adjusting wheel 212 rotates, the contact area between the long side wall above it and the transmission belt 16 gradually decreases, and at the same time, the contact area between the short side wall of the adjusting wheel 212 and the transmission belt 16 gradually increases. In this process, the transmission belt 16 is pushed upward by the short side wall of the adjusting wheel 212 to deform, and at the same time, the nail plate 161 and the workpiece or waste above it are lifted upward, and when the adjusting wheel 212 continues to rotate, the contact area between the short side wall of the adjusting wheel 212 and the transmission belt 16 gradually decreases, and at the same time, the contact area between the long side wall of the adjusting wheel 212 and the transmission belt 16 gradually increases. In this process, the transmission belt 16 is pressed against the transmission belt 16 under the action of elasticity. The long side wall of the regulating wheel 212 near the bottom is restored until the transmission belt 16 returns to the horizontal level, and at the same time, the workpiece or waste material above the nail plate 161 moves downward, so that the workpiece or waste material is vibrated back and forth during the continuous rotation of the regulating wheel 212. At this time, the stress concentration point of the contact point between the waste material and the workpiece is gradually loosened due to repeated vibration, thereby achieving separation during the blanking process, abandoning the subsequent operation of manually separating the two, improving the overall separation efficiency, and at the same time, the flexible separation method of vibration is used, and the force generated by the vibration is concentrated at the clamping part, which can effectively promote the breakage of burrs and the loosening of the nested structure, thereby protecting the structure of the workpiece from damage, ensuring that the dimensional tolerance of the produced workpiece meets the requirements, and ensuring the production quality of the product; It should be noted that: if the plate is a base material and workpieces of different shapes need to be cut from it, the cut workpieces will fall onto the sieve plate 17 below together with the debris. When the sieve plate 17 is in a stable state and the long side wall of the adjusting wheel 212 is close to the sieve plate 17, there is a gap between the two. At this time, the side wall of the rotating adjusting wheel 212 will continuously press against one end of the lower sieve plate 17 during the rotation. When the short side wall of the adjusting wheel 212 abuts against the sieve plate 17, one end of the sieve plate 17 squeezes the spring 191 below and the other end bends and rotates downward through the rotating shaft 171. When the adjusting wheel 212 rotates, the sieve plate 17 and the adjusting wheel 212 are in contact from the short side wall to the long side wall at the moment of contact. The short side walls of the wheel 212 are quickly separated. At this time, the screen plate 17 bounces up quickly and vibrates under the rebound action of the spring 191. The screen plate 17 is continuously vibrated during the rotation of the adjusting wheel 212, and the debris on the surface of the workpiece is dropped by vibration. For workpieces with holes, the debris hidden in the gaps can be shaken out, thereby improving the cleaning effect of the debris on the surface of the workpiece. At the same time, the alternating force generated by the vibration breaks the friction and adsorption force between the debris, so that the debris can continuously adjust its posture and quickly pass through the sieve hole, thereby accelerating the debris to pass through the screen plate 17 and reducing blockage, thereby improving the screening effect of the debris, thereby improving the cleaning intensity of the debris and further ensuring the subsequent production quality.

[0027] For example three, please refer to Figure 5 、 Figure 12 and Figure 13 On the basis of the second embodiment, in order to prevent the debris from adhering to the side wall of the nail plate 161 and causing accumulation to affect the unloading of the workpiece.

[0028] Furthermore, a cleaning assembly 4 is installed inside the cutting table 1. The cleaning assembly 4 includes a slider 42. The two sliders 42 are respectively arranged on the outside of the two reciprocating screws 41. The outer wall of the reciprocating screw 41 is connected to the slider 42 for transmission. An air pipe 43 is fixedly connected between the two sliders 42. The upper side wall of the air pipe 43 is provided with a plurality of equidistant air holes 44. A telescopic connecting pipe 45 is fixedly connected to the inner wall of one side of the air pipe 43. An air pump 46 is installed on the outer wall of one side of the cutting table 1. The output end of the air pump 46 is fixedly connected to one end of the telescopic connecting pipe 45; It should be noted that: during the process of blanking, the adjusting wheels 212 near the two ends of the cutting table 1 are rotating, and at the same time, the two reciprocating screws 41 in the middle are driven to rotate. During the rotation of the reciprocating screw 41, the slider 42 on the outside thereof is driven to slide. At the same time, the air pipe 43 between the sliders 42 is driven to move. The design of the reciprocating screw 41 makes the air pipe 43 slide back and forth on the inner wall of the cutting table 1. At this time, the air pump 46 is started to inflate the air pipe 43 through the telescopic connecting pipe 45. After that, the gas inside the air pipe 43 is continuously ejected upward through the multiple air holes 44 opened on the upper side wall thereof. The ejected gas continuously impacts the side wall of the upper nail plate 161, removing the debris adhering to the side wall. The impact is performed to break the adsorption force between the chips and the nail plate 161, and at the same time an upward airflow channel is formed through the gap between the nail plates 161, which blows the chips hidden between the nail tips away from the surface of the nail plate 161, avoiding the accumulation of a chip layer on the surface of the nail plate 161, thereby helping the chips to break away from the nail plate 161 and reduce retention, thereby improving the efficiency of the chips falling through the gaps between the nail plates 161. At the same time, when the workpiece falls on the nail plate 161 after cutting, it may rest on the adjacent nail plate 161 due to its tilted posture. The upward airflow can slightly lift the workpiece upward, and cooperate with the vibration of the nail plate 161 to help the workpiece adjust its posture and fall through the gap between the nail plates 161, thereby reducing the probability of jamming, thereby further improving the workpiece unloading effect.

[0029] It should be noted that the specific model specifications of the electrical components need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0030] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
