Description

Technical Field

[0001] This invention relates to the field of profile steel processing, specifically to a profile steel loading and unloading device and a profile steel laser cutting equipment. Background Technology

[0002] Electromagnets can attract magnetic materials, and taking advantage of this property, electromagnet feeding devices are often used for handling structural steel.

[0003] Existing electromagnet feeding devices, as described in patent application number CN201210580711.1, use electromagnets to attract steel profiles and then move them to a designated position. However, in actual use, the steel profiles are prone to being placed at an angle, making it difficult for the electromagnets to adhere to them and thus hindering successful attraction.

[0004] Therefore, how to make the magnetic suction component adhere to and attract the tilted steel profile is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and to propose a steel section loading and unloading device and a steel section laser cutting equipment, thereby solving the technical problem that magnetic suction components are difficult to attach and pick up tilted steel sections in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a steel section loading and unloading device, comprising: The truss has a loading area, an exchange and processing area, and an unloading area arranged side by side below it. The loading assembly includes a first magnetic suction component, a first robotic arm, and a limiting component. The first magnetic suction component is used to attract structural steel. One end of the first robotic arm is connected to the truss, and the other end has a swingable component connected to the first magnetic suction component, which drives the first magnetic suction component to reciprocate between the loading area and the processing area. The limiting component is mounted on the first robotic arm and has a first state of pressing against the first magnetic suction component to prevent the first magnetic suction component from rotating relative to the first robotic arm, and a second state of disengaging from the first magnetic suction component to allow the first magnetic suction component to rotate relative to the first robotic arm. The unloading assembly includes a second magnetic suction component and a second robotic arm. The second magnetic suction component is used to attract steel profiles. One end of the second robotic arm is connected to the frame, and the other end is connected to the second magnetic suction component. The robotic arm drives the second magnetic suction component to reciprocate between the unloading area and the processing area.

[0007] In some embodiments, the first magnetic suction member includes a first base, a first electromagnet, and a first telescopic drive member. The first base is rotatably mounted on the first robotic arm, the first electromagnet is slidably disposed on the first base, and the first telescopic drive member is throttle-connected to the first electromagnet, thereby causing the first electromagnet to slide relative to the first base.

[0008] In some embodiments, the first base includes a base and a sub-base. The base is rotatably mounted on the first robotic arm, and the sub-base is rotatably mounted on the base, with the rotation axis of the sub-base perpendicular to the rotation axis of the base. The first electromagnet is slidably disposed on the sub-base.

[0009] In some embodiments, the limiting member includes a first pressing seat, a first limiting cylinder, a second pressing seat, and a second limiting cylinder. The first pressing seat is slidably disposed on the first robotic arm. The first limiting cylinder is throttle-connected to the first pressing seat, which drives the first pressing seat to disengage from or press against the base. The second pressing seat is slidably disposed on the base. The second limiting cylinder is throttle-connected to the second pressing seat, which drives the second pressing seat to disengage from or press against the sub-seat.

[0010] In some embodiments, there are two first magnetic suction members, which are arranged side by side on the first robotic arm. There are also two limiting members, and each of the two limiting members corresponds to one of the two first magnetic suction members.

[0011] In some embodiments, the second magnetic attractor includes two opposing magnetic attracting portions, both of which are slidably disposed on the magnetic attracting portion so that the two magnetic attracting portions move closer and further away from each other, and the magnetic attracting portion has the magnetic force to attract steel.

[0012] In some embodiments, the magnetic attraction part includes a support frame, a second electromagnet, and an elastic unit. The support frame is slidably disposed on the second robotic arm, the second electromagnet is slidably disposed on the support frame, and the two ends of the elastic unit are respectively connected to the second electromagnet and the support frame. The elastic unit has an elastic force that pushes the second electromagnet away from the support frame.

[0013] In some embodiments, the second electromagnet is a bar electromagnet.

[0014] In some embodiments, the magnetic suction part further includes a plurality of supporting claws and a plurality of supporting cylinders. The plurality of supporting claws are arranged along the length direction of the support frame, and one end of each supporting claw is rotatably mounted on the support frame. The plurality of supporting cylinders correspond one-to-one with the plurality of supporting claws. The cylinder body of the supporting cylinder is hinged to the support frame, and the piston rod of the supporting cylinder is hinged to the supporting claw. The supporting cylinder drives the supporting claw to rotate so that the supporting claw supports or moves away from the bottom of the profile steel.

[0015] Secondly, the present invention also provides a laser cutting device for profile steel, which is equipped with the above-mentioned profile steel loading and unloading device.

[0016] Compared with the prior art, the steel section loading and unloading device provided by the present invention has the following advantages: The loading area is used to place the steel sections to be processed, the processing area is used to process the steel sections, and the unloading area is used to place the processed steel sections. First, the first robotic arm moves the first magnetic suction device to the loading area, bringing it close to the steel section to be processed. Since the first magnetic suction device can rotate relative to the first robotic arm, it can adhere to the inclined steel section. After the first magnetic suction device picks up the steel section, the first robotic arm lifts it. Then, the limiting device can be switched from the second state to the first state, thus restricting the rotation of the first magnetic suction device and preventing the steel section from swaying during lifting. The steel section is then placed in the processing area. After processing, the second magnetic suction device and the second robotic arm can be used to move the processed steel section from the processing area to the unloading area. This steel section loading and unloading device ensures that the first magnetic suction device adheres to the inclined steel section, guaranteeing smooth suction for subsequent steel section handling.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] To address the technical problem that magnetic components have difficulty adhering to and picking up tilted steel profiles, this invention provides a steel profile loading and unloading device, wherein the magnetic components can rotate, allowing the magnetic components to adhere to the steel profiles and ensuring that the magnetic components can successfully pick up the steel profiles.

[0020] It should be noted that the steel loading and unloading device of the present invention is used in, but not limited to, steel laser cutting equipment. For ease of explanation, this invention will only use the application of the steel loading and unloading device in steel laser cutting equipment as an example. The principle of the steel loading and unloading device in other types of devices is essentially the same as that in steel laser cutting equipment, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1This is a schematic diagram of the steel section loading and unloading device in one embodiment of the present invention. The steel section loading and unloading device includes a truss 100, a loading assembly 200, and a unloading assembly 300. A loading area 110, an exchange processing area 120, and an unloading area 130 are arranged side-by-side below the truss 100. The loading assembly 200 includes a first magnetic suction component 210, a first robotic arm 220, and a limiting component 230. The first magnetic suction component 210 is used to attract the steel section. One end of the first robotic arm 220 is connected to the truss 100, and its other end has a swingable component connected to the first magnetic suction component 210, which drives the first magnetic suction component 210 to reciprocate between the loading area 110 and the processing area 120. The limiting component 230... The component 230 is mounted on the first robotic arm 220, and the limiting component 230 has a first state of pressing against the first magnetic 210 to prevent the first magnetic 210 from rotating relative to the first robotic arm 220, and a second state of disengaging from the first magnetic 210 to allow the first magnetic 210 to rotate relative to the first robotic arm 220. The unloading assembly 300 includes a second magnetic 310 and a second robotic arm 320. The second magnetic 310 is used to attract steel profiles. One end of the second robotic arm 320 is connected to the truss 100, and the other end is connected to the second magnetic 310. It drives the second magnetic 310 to reciprocate between the unloading area 130 and the processing area 120.

[0022] In this embodiment, the loading area 110 is used to place the steel section to be processed, the processing area 120 is used to process the steel section, and the unloading area 130 is used to place the processed steel section. First, the first robotic arm 220 moves the first magnetic suction member 210 to the loading area 110, bringing it close to the steel section to be processed. Since the first magnetic suction member 210 can rotate relative to the first robotic arm 220, it can adhere to the inclined steel section. After the first magnetic suction member 210 picks up the steel section, the first robotic arm 220 lifts it. Then, the limiting member 230 can be switched from the second state to the first state, thereby restricting the rotation of the first magnetic suction member 210 and preventing the steel section from swaying during lifting. The steel section is placed in the processing area 120. After processing is completed, the second magnetic suction member 310 and the second robotic arm 320 can be used to move the processed steel section from the processing area 120 to the unloading area 130. The above-mentioned steel loading and unloading device allows the first magnetic suction component 210 to adhere to the inclined steel section, ensuring that the first magnetic suction component 210 can smoothly attract the steel section, which facilitates subsequent steel section handling.

[0023] It should be noted that the selection of the first robotic arm 220 and the second robotic arm 320 is diverse. For example, the first robotic arm 220 and the second robotic arm 320 can be rotary robotic arms, spider robotic arms, etc., but in this application... Figure 1 In the embodiments shown, the first robotic arm 220 and the second robotic arm 320 are both basic three-degree-of-freedom robotic arms.

[0024] In some embodiments, the first magnetic attractor 210 includes a first base 211, a first electromagnet 212, and a first telescopic drive 213. The first base 211 is rotatably mounted on the first robotic arm 220. The first electromagnet 212 is slidably disposed on the first base 211. The first telescopic drive 213 is drively connected to the first electromagnet 212, causing the first electromagnet 212 to slide relative to the first base 211. By moving the first electromagnet 212 relative to the first base 211 via the first telescopic drive 213, the relative position of the first electromagnet 212 and the profile steel can be finely adjusted. Since the first base 211 can rotate relative to the first robotic arm 220, when the first electromagnet 212 contacts the profile steel, the first electromagnet 212 can rotate with the first base 211, allowing the first electromagnet 212 to adapt to the tilt angle of the profile steel, thereby adhering to the surface of the profile steel and ensuring that the first electromagnet 212 can successfully attract the profile steel.

[0025] In some embodiments, the first base 211 includes a base 2111 and a sub-base 2112. The base 2111 is rotatably mounted on the first robotic arm 220, and the sub-base 2112 is rotatably mounted on the base 2111, with the rotation axis of the sub-base 2112 perpendicular to the rotation axis of the base 2111. The first electromagnet 212 is slidably disposed on the sub-base 2112. Regardless of the direction in which the steel profile is tilted, the first electromagnet 212 can adhere to the steel profile.

[0026] In some embodiments, the limiting member 230 includes a first pressing seat 231, a first limiting cylinder 232, a second pressing seat 233, and a second limiting cylinder 234. The first pressing seat 231 is slidably disposed on the first robotic arm 220. The first limiting cylinder 232 is operatively connected to the first pressing seat 231, causing the first pressing seat 231 to disengage from or press against the base 2111. The second pressing seat 233 is slidably disposed on the base 2111. The second limiting cylinder 234 is operatively connected to the second pressing seat 233, causing the second pressing seat 233 to disengage from or press against the sub-seat 2112. The first limiting cylinder 232 pushes the first pressing seat 231, causing the first pressing seat 231 to press against the base 2111, thereby limiting the rotation of the base 2111. Furthermore, keeping the first pressing seat 231 horizontal forces the base 2111 to remain horizontal. Similarly, the second limiting cylinder 234 pushes the second pressing seat 233, causing the second pressing seat 233 to press against the sub-seat 2112, thereby restricting the rotation of the sub-seat 2112 and keeping the second pressing seat 233 horizontal, thus forcing the sub-seat 2112 to remain horizontal.

[0027] In some embodiments, there are two first magnetic suction members 210, arranged side by side on the first robotic arm 220. There are also two limiting members 230, each corresponding to one of the two first magnetic suction members 210. If the width of the steel profile is small, one magnetic suction member can be used to hold it in place; if the width of the steel profile is large, two magnetic suction members can be used to hold it in place, thus achieving a more secure hold.

[0028] See also Figure 4 After the steel profile is laser-cut, it becomes several small segments. If conventional electromagnets are used to attract all these segments, the smaller segments, due to their smaller size and weight, are easily flipped uncontrollably under the influence of magnetism, causing the arrangement and order of the segments to become disordered. The unloading assembly 300 is used to move the several small steel segments from the processing area 120 to the unloading area 130 as a whole.

[0029] To address the aforementioned technical problems, in some embodiments, the second magnetic suction member 310 includes two opposing magnetic suction portions 311. Both magnetic suction portions 311 are slidably disposed on the magnetic suction portion 311, allowing them to move closer and further apart. Each magnetic suction portion 311 possesses the magnetic force to attract the steel section. The two magnetic suction portions 311 are respectively disposed on both sides of several small steel sections. The two magnetic suction portions 311 work together to move each small steel section. Because the two magnetic suction portions 311 act as a limiting element, they prevent the small steel sections from moving or flipping relative to the magnetic suction portions 311, thus maintaining the neat arrangement and order of the small steel sections during the moving process.

[0030] Based on the above embodiments, in some embodiments, the magnetic suction part 311 includes a support frame 3111, a second electromagnet 3112, and an elastic unit 3113. The support frame 3111 is slidably disposed on the second robotic arm 320, and the second electromagnet 3112 is slidably disposed on the support frame 3111. The two ends of the elastic unit 3113 are respectively connected to the second electromagnet 3112 and the support frame 3111. The elastic unit 3113 has a spring force that pushes the second electromagnet 3112 away from the support frame 3111. Since the elastic unit 3113 has a spring force that pushes the second electromagnet 3112 away from the support frame 3111, when the support frame 3111 pushes the electromagnet to contact the small section of steel, it will overcome the spring force of the elastic unit 3113, causing the second electromagnet 3112 to move closer to the support frame 3111, thus avoiding excessive pressure applied by the second electromagnet 3112 to the small section of steel and preventing the small section of steel from being deformed under pressure.

[0031] In some embodiments, the second electromagnet 3112 is a bar electromagnet, which allows the second electromagnet 3112 to simultaneously attract all the small sections of steel.

[0032] In some embodiments, the magnetic suction unit 311 further includes a plurality of supporting claws 3114 and a plurality of supporting cylinders 3115. The plurality of supporting claws 3114 are arranged along the length of the support frame 3111, and one end of each supporting claw 3114 is rotatably mounted on the support frame 3111. The plurality of supporting cylinders 3115 correspond one-to-one with the plurality of supporting claws 3114. The cylinder body of the supporting cylinder 3115 is hinged to the support frame 3111, and the piston rod of the supporting cylinder 3115 is hinged to the supporting claw 3114. The supporting cylinder 3115 drives the supporting claws 3114 to rotate, so that the supporting claws 3114 support or move away from the bottom of the steel section. The supporting cylinders 3115 drive the supporting claws 3114 to rotate. During the process of handling each small section of steel, the supporting cylinders 3115 can drive the supporting claws 3114 to support each small section of steel, thereby preventing the small sections of steel from falling off during the handling process.

[0033] Secondly, the present invention also provides a laser cutting device for profile steel, which is equipped with the above-mentioned profile steel loading and unloading device.

[0034] To better understand this invention, the following is combined with... Figures 1 to 4 The technical solution of the present invention will be described in detail below: The loading area 110 is used to place the steel profiles to be processed, the processing area 120 is used to process the steel profiles, and the unloading area 130 is used to place the processed steel profiles. First, the first robotic arm 220 drives the first magnetic suction component 210 to move to the loading area 110, so that the first magnetic suction component 210 is close to the steel profile to be processed. Since the first magnetic suction component 210 can rotate relative to the first robotic arm 220, when the first electromagnet 212 contacts the steel profile, the first electromagnet 212 can rotate with the first base 211, so that the first electromagnet 212 can adapt to the tilt angle of the steel profile, and thus adhere to the surface of the steel profile, ensuring that the first electromagnet 212 can successfully attract the steel profile. After the first electromagnet 212 attracts the steel section, the first robotic arm 220 lifts the steel section. Then, the limiting member 230 is switched from the second state to the first state, causing the first pressing seat 231 to press against the base 2111, thus limiting the rotation of the base 2111. The second pressing seat 233 presses against the dividing seat 2112, thus limiting the rotation of the dividing seat 2112. This restricts the rotation of the first electromagnet 212, preventing the steel section from swaying during lifting. The steel section is placed in the processing area 120. After processing, two magnetic suction parts 311 are respectively positioned on both sides of several small steel sections. The two magnetic suction parts 311 work together to move each small steel section. Because the two magnetic suction parts 311 act as limiting parts, they prevent the small steel sections from moving or flipping relative to the magnetic suction parts 311, thus maintaining the neatness of the placement and order of the small steel sections during the moving process. The cut steel sections are smoothly transferred from the processing area 120 to the unloading area 130. The steel loading and unloading device allows the first magnetic suction component 210 to adhere to the tilted steel section, ensuring smooth magnetic attraction and facilitating subsequent handling. Furthermore, after cutting, the entire steel section can be moved as a whole, maintaining its neat arrangement and order during transport.
