Description

Technical Field

[0001] This invention relates to the field of plasma cutting technology for die-cast parts, and more particularly to a plasma cutting station for die-cast parts based on 3D vision guidance. Background Technology

[0002] In recent years, plasma cutting technology has become an important means of cleaning up gating gates, flash, and burrs in the die casting production process due to its advantages such as fast cutting speed, smooth cut, and small heat-affected zone. At the same time, with the continuous maturation of industrial robot technology and the continuous improvement of the cutting accuracy requirements of die casting scrap, 3D vision-guided plasma cutting devices have emerged. This device uses a 3D industrial camera to collect the three-dimensional contour information of the die casting and plans the cutting trajectory according to the identified workpiece position and posture, guiding the robot to complete high-precision automated cutting, thereby solving the problems of low efficiency, high labor intensity, and unstable cutting quality of traditional manual operation. However, automated cutting devices still face significant shortcomings in dust removal during practical use. On the one hand, the high-temperature fumes generated during the cutting of die-cast parts by plasma cutting devices can easily contaminate the 3D camera lens, shortening the imaging accuracy and lifespan of its vision system. On the other hand, most existing dust removal structures are fixed, making it difficult to keep them aligned with the source of fumes when the robotic arm is making complex spatial movements, resulting in difficulty in ensuring the efficiency of fumes collection. Therefore, a 3D vision-guided plasma cutting station for die-cast parts is proposed to solve the above problems. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figures 1-17A plasma cutting station for die casting based on 3D vision guidance includes a main body 1 and a cutting gun 10. A robotic arm 2 is fixedly installed on the bottom wall of the main body 1. A support rod 6 is fixedly installed at the end of the robotic arm 2. A bracket 11 is fixedly installed on the support rod 6. A camera 12 is fixedly installed on the bracket 11. A blocking component 8 for blocking the lens of the camera 12 is provided on the robotic arm 2. A gathering component 9 for gathering and collecting cutting fumes is provided on the support rod 6.

[0018] The sealing assembly 8 includes a rotating shaft 84 rotatably mounted on the camera 12, a sealing plate 88 fixedly mounted on the rotating shaft 84, a torsion spring 87 fixedly mounted between the sealing plate 88 and the camera 12, and a drive mechanism mounted on the rotating shaft 84.

[0019] The drive mechanism includes a conduit 81 that passes through and is fixedly installed on the bracket 11. A conduit 81 is fixedly connected to a contraction tube 82. One end of a rotating shaft 84 is sealed through and rotatably installed on the contraction tube 82. A connecting pipe 83 is fixedly connected between the contraction tube 82 and the support rod 6. A baffle 85 is fixedly installed on the rotating shaft 84 and is rotatably installed inside the contraction tube 82. A stop block 86 is fixedly installed on the inner wall of the contraction tube 82. An air supply component is installed on the robotic arm 2.

[0020] The air supply components include a fan 4 fixedly installed on the robotic arm 2 (the fan 4 is a conventional product, and its specific working principle and internal components are well known in the art, so they will not be described in detail here). An air supply pipe 5 is fixedly connected to the fan 4, and one end of the air supply pipe 5 is connected to the conduit 81.

[0021] When the device is needed to cut die-cast parts, the die-cast parts are first transported to the bottom of the robotic arm 2 using the existing conveying equipment on the main body 1. Then, the robotic arm 2 and camera 12 are started simultaneously. After the camera 12 and robotic arm 2 work together to scan and collect the contour and position information of the die-cast parts, the collected data information is transmitted to the existing control system on the main body 1 (the conveying equipment and control system are existing technologies and are not the contents to be protected by this invention, so they will not be described in detail here). The control system will automatically plan the cutting path of the robotic arm 2 according to the received three-dimensional contour data, and control the robotic arm 2 to drive the cutting gun 10 to move according to the planned cutting trajectory, and start the plasma cutting operation on the die-cast parts.

[0022] When the robotic arm 2 moves and drives the cutting gun 10 to begin cutting the die-cast part, the camera 12 is stopped first, and then the fan 4 is started. The fan 4 draws outside gas into its interior, and the gas flows into the contraction tube 82 along the connection path between the gas supply pipe 5 and the conduit 81, and continues to flow to the right (along...). Figure 7(As shown in the direction), during this process, according to the Venturi effect, when the airflow passes through the contraction section of the contraction tube 82, the flow velocity will increase accordingly as the cross-sectional area decreases, and the static pressure will also decrease accordingly. The airflow will be gradually accelerated in this contraction section, and finally flow out at high speed at the right end outlet of the contraction tube 82. At this time, the driving force generated by the high-speed airflow on the baffle 85 can drive the baffle 85 to rotate clockwise around the axis 84 (along the direction shown in the figure). Figure 9 The direction shown, combined with Figure 9 It can be seen that when the gas flows continuously to the right and impacts the baffle 85, the baffle 85 can only rotate clockwise due to the obstruction of the lower right side of the baffle 85 by the block 86.

[0023] When the baffle 85 is subjected to force and rotates clockwise around the pivot 84 (along... Figure 9 (As shown in the direction), the baffle 85 will drive the sealing plate 88 to rotate synchronously through the rotating shaft 84 (when the sealing plate 88 is rotated under force, it will drive one end of the torsion spring 87 to rotate together, so that the torsion spring 87 will generate elastic torsional deformation and store elastic potential energy), until the airflow drives the baffle 85 to rotate to the lower end of the connection between the contraction tube 82 and the connecting tube 83. At this time, the airflow will flow into the interior of the connecting tube 83 along the connection between the contraction tube 82 and the connecting tube 83, realizing the air passage. At the same time, when the baffle 85 is rotated to the lower end of the connection between the contraction tube 82 and the connecting tube 83 and stops rotating, the sealing plate 88, which is linked with the rotating shaft 84, just completes the complete blocking of the lens of the camera 12. This can avoid the pollution of the lens of the camera 12 by the smoke and dust generated during the subsequent cutting of the die-casting parts, which helps to improve the imaging accuracy and service life of the overall vision system of the camera 12, as well as improve the accuracy of the continuous cooperation between the camera 12 and the robotic arm 2 in cutting the die-casting parts.

[0024] Furthermore, when the baffle 85 is rotated to the lower end of the connection between the contraction tube 82 and the connecting tube 83 and stops rotating, the airflow inside the contraction tube 82 continues to flow at high speed into the connecting tube 83. During this process, the high-speed airflow will continuously exert an impact force on the surface of the baffle 85 in the direction of the connection. The direction of this impact force is exactly opposite to the direction in which the torsion spring 87 drives the baffle 85 to reset. Since the fan 4 always maintains an air supply state during the cutting process, the impact force of the airflow continues to exist. Therefore, during the cutting of the die casting, the baffle 85 will always remain in the current position, which can ensure the blocking effect of the baffle 85, the rotating shaft 84 and the sealing plate 88 on the lens of the camera 12 during the cutting of the die casting.

[0025] Reference Figures 11-15 The gathering component 9 includes a cylinder 7 fixedly mounted on a support rod 6, a turntable 93 rotatably mounted on the cylinder 7, a force transmission component mounted on the cylinder 7, a gathering cover 94 fixedly mounted on the turntable 93, an air blowing component mounted on the gathering cover 94, and an air extraction mechanism mounted on the cylinder 7.

[0026] The power transmission component includes air outlet holes 95 that are evenly and annularly opened on the cylinder 7, and plates 96 that are evenly and annularly distributed are fixedly installed on the inner wall of the turntable 93.

[0027] The air blowing component includes an arc-shaped opening 97 evenly distributed in a ring on the turntable 93, an air blowing groove 910 on the gathering cover 94, and an arc-shaped opening 99 evenly distributed in a ring on the gathering cover 94. The arc-shaped openings 99 are all connected to the corresponding arc-shaped opening 97, and the arc-shaped openings 99 are all connected to the air blowing groove 910.

[0028] After the gas continues to flow along the inner wall of the connecting pipe 83 and enters the inner cavity of the support rod 6, the airflow will continue to flow to the right along the connection path between the support rod 6 and the cylinder 7 (along...). Figure 11 (As shown in the direction), the gas is finally ejected at high speed from the narrowed air outlet 95 and enters the interior of the turntable 93. The gas entering the interior of the turntable 93 continues to flow along the connecting channel formed by the adjacent arc-shaped opening 97 and arc-shaped opening 99, into the air-blowing groove 910 on the gathering cover 94, and finally ejected from the left end of the air-blowing groove 910. During this process, combined with Figure 14 and Figure 15 As can be seen, due to the narrow overall width of the air blowing groove 910, its flow cross-sectional area is much smaller than that of the front flow channel. Based on the principle of fluid continuity and the Venturi effect, the gas is further compressed and accelerated when flowing through the narrow channel, so that the airflow ejected from the outlet of the air blowing groove 910 is a flat high-speed jet, forming a flat and high-speed annular air curtain around the cutting gun 10. This annular air curtain can effectively cover the cutting area and can gather the high-temperature smoke and dust generated during the cutting of the die casting by the cutting gun 10 into the air curtain, preventing it from spreading outward and creating favorable conditions for subsequent centralized dust extraction.

[0029] And combined Figure 13 As can be seen, the air outlets of multiple air outlets 95 are all tilted to one side of the corresponding plate 96. When the air outlet 95 with a narrower air diameter is ejected at high speed, the tilted air outlet of the air outlet 95 will guide the high-speed airflow to impact the surface of the plate 96 at an angle. At this time, the airflow impact force generates a tangential component force on the plate 96, which will form a driving torque relative to the rotation center of the turntable 93, thereby driving the plate 96 together with the turntable 93 to rotate continuously around the axis of the cylinder 7.

[0030] When the turntable 93 is driven by force to rotate the gathering cover 94 synchronously, the annular air curtain ejected from the air blowing groove 910 will produce a dynamic rotation effect around the cutting gun 10. This helps to improve the stability and uniformity of the annular air curtain, and improve the gathering effect of the air curtain on the smoke and dust generated during the cutting process. At the same time, since the air curtain is always rotating, even if the smoke and dust generated during the cutting of the die-casting part collide with the air curtain outward under the action of high thermal expansion force, the rotating airflow can continuously guide and gather the smoke and dust towards the center of the cutting area, reducing the local accumulation and penetration of smoke and dust in the air curtain. This helps to further improve the gathering effect of the device on smoke and dust, and improve the subsequent capture effect of the device on smoke and dust.

[0031] Reference Figures 4-17 The air extraction mechanism includes a ring 91 fixedly installed on a cylinder 7. A conical cylinder 92 is fixedly installed between the ring 91 and the cylinder 7. The cylinder 7 has air inlets 98 evenly distributed in a ring shape, and all air inlets 98 are connected to the conical cylinder 92. A transmission component is installed on the cylinder 7, and an air suction component is installed inside the ring 91.

[0032] The transmission component includes a rotating rod 913 that is sealed through and rotatably mounted on a cylinder 7, and the rotating rod 913 is sealed through and rotatably mounted on a ring 91. A ring-shaped blade 914 is fixedly mounted on the rotating rod 913, and two eccentric wheels 915 are fixedly mounted on the rotating rod 913.

[0033] The intake component includes a one-way exhaust pipe 911 and two one-way intake pipes 912 fixedly connected to the ring 91. The ring 91 is fixedly connected to two one-way intake pipes 912. The main body 1 of the device is fixedly installed with a purifier 3 that cooperates with the one-way exhaust pipe 911 (the purifier 3 is a conventional product, and its specific working principle and internal components are well known in the art. It is not shown in detail in the accompanying drawings of the specification, so it will not be described in detail here. At the same time, one end of the one-way exhaust pipe 911 is connected to the purifier 3). Two compression springs 916 are fixedly installed on the inner wall of the ring 91. A sealing plate 917 that cooperates with two eccentric wheels 915 is fixedly installed between the two compression springs 916, and the sealing plate 917 is slidably installed on the inner wall of the ring 91.

[0034] As the gas flows to the right along the inner wall of the support rod 6 and the cylinder 7, the force generated by the airflow contracting and accelerating through the constriction section of the cylinder 7 drives multiple blades 914 to rotate continuously around the rotating rod 913. During this rotation of the rotating rod 913 and the two eccentric wheels 915, the two eccentric wheels 915 intermittently apply an upward thrust to the sealing plate 917, and the two compression springs 916 intermittently apply a reset driving force to the sealing plate 917, causing the sealing plate 917 to move up and down reciprocally (along the...). Figure 17direction shown).

[0035] As the sealing plate 917 moves intermittently upward under force, the volume of the sealed cavity below the sealing plate 917 gradually increases, and the air pressure inside the annular ring 91 gradually decreases, forming a local negative pressure. At this time, the dust gathered inside the air curtain and the gathering hood 94 will enter the inner cavity of the annular ring 91 through the connecting path between the air inlet 98, the inner wall of the conical cylinder 92, and the one-way air inlet pipe 912 under the action of atmospheric pressure, and finally be discharged from the one-way exhaust pipe 911. In this way, the dust generated during the cutting of the die casting by the cutting gun 10 can be gathered and collected in a timely manner. This not only helps to prevent the dust from accumulating in the air curtain and breaking through the air curtain barrier to spread outward, but also ensures the clarity of the field of vision in the cutting area, helps to reduce the interference of dust on the stability of the plasma arc, improves the consistency of the cutting quality of the die casting and the reliability of the long-term operation of the device.

[0036] Meanwhile, during the cutting process of the cutting gun 10, the purifier 3 is activated. Since one end of the one-way exhaust pipe 911 is connected to the purifier 3, the dust entering the one-way exhaust pipe 911 will flow into the purifier 3 along the pipe. The purifier 3 will filter and purify the dust gas before discharging it outward. This can effectively prevent dust-laden gas from being directly discharged into the workshop environment, reducing the pollution hazards to the health of operators and the surrounding environment.

[0037] After the die casting is cut, the operation of the robotic arm 2, the cutting gun 10 and the fan 4 can be stopped, that is, the continuous air supply to the shrink tube 82 is stopped. At this time, under the elastic potential energy released by the torsion spring 87 and the gravity of the sealing plate 88, the sealing plate 88 can drive the rotating shaft 84 and the baffle 85 to move and reset, so that the camera 12 can scan and acquire the contour of the next die casting to be cut.

[0038] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0039] In this invention, before using the device to cut die-cast parts, the die-cast parts are first transported to the underside of the robotic arm 2 by the existing conveying equipment on the main body 1 of the device. Then, the robotic arm 2 and camera 12 are started. After the camera 12 and robotic arm 2 complete the contour scanning and acquisition of the die-cast parts, the operation of the camera 12 can be stopped. Based on the scan acquisition information, the robotic arm 2 is controlled to drive the cutting gun 10 to move according to the planned cutting trajectory to start the plasma cutting operation on the die-cast parts. At the same time, the fan 4 is started. During the operation of the fan 4, air is supplied into the shrink tube 82. The sealing plate 88 can be driven to rotate to block the lens of the camera 12 through the drive mechanism. This can avoid the dust generated during the subsequent cutting of the die-cast parts by the device from contaminating the lens of the camera 12. This helps to improve the imaging accuracy and service life of the overall vision system of the camera 12, as well as improve the accuracy of the continuous cooperation between the camera 12 and the robotic arm 2 in cutting the die-cast parts.

[0040] Meanwhile, through the cooperation of the blower 4 and the gathering component 9, the air outlet 910 on the gathering cover 94 can spray out a high-speed airflow, forming a high-speed air curtain around the cutting torch 10. This high-speed air curtain effectively gathers the smoke and dust generated during cutting, while the suction mechanism promptly removes the gathered smoke and dust. This not only helps to prevent the smoke and dust from accumulating in the air curtain and breaking through the air curtain barrier to spread outward, but also ensures the clarity of the field of view in the cutting area, helps to reduce the interference of smoke and dust on the stability of the plasma arc, and improves the consistency of the cutting quality of the die-casting parts and the long-term reliability of the device.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
