Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, and in particular to a laser cutting device and an operating method for processing English labels on steel structures. Background Art

[0002] The laser cutting device for processing English signage on steel structures is an efficient and precise processing equipment. It uses the high energy density characteristics of the laser beam to perform non-contact cutting processing on steel structure materials. It is particularly suitable for making fine parts such as English signage. The laser cutting device generates a high energy density laser beam through a laser, which is focused by an optical system and irradiated onto the surface of the material. After the energy of the laser beam is absorbed by the material, it is quickly converted into heat energy, causing the material to partially melt or vaporize. At the same time, the slag is blown away with the help of high-speed airflow, thereby achieving cutting processing; When engraving English signs on the surface of steel structures, laser cutting does not directly use "tools" in the traditional sense, because laser cutting uses a high-energy laser beam to directly act on the surface of the material to melt, vaporize or reach the ignition point of the material, thereby achieving the purpose of cutting. However, in actual operation, the local surface of the steel structure is often adhered to oil stains due to storage, transportation and other reasons. These oil stains adhered to the surface of the steel structure will affect the effect of laser cutting, making the processed English signs prone to slag. The appearance of slag will affect the processing quality of the English signs. For this reason, we propose a laser cutting device and operation method for processing English signs on steel structures. Summary of the invention

[0013] An operating method of a laser cutting device for processing English signboards on steel structures specifically comprises the following steps: S1. The cutting machine processes the English label on the steel structure on the machine tool. First, the cutting machine drives the connection part to move synchronously by rotating the sleeve, and the detection sleeve on the connection part moves synchronously with it. During the movement, the detection rod frame drives the oil detection element to move synchronously. The oil detection element can be used to know the oil condition on the surface of the steel structure; S2. When encountering an arc-shaped curved steel structure plate, the arc baffle will first contact the raised area, and then the raised area of ​​the steel structure plate will first act on the arc baffle. The arc baffle is acted upon by a force so that the extended shaft moves toward the inside of the oil detection element. The sensing element is triggered, and once the electric magnetic group is energized, an attractive force is generated on the annular magnetic plate, so that the detection rod frame performs a directional upward movement inside the detection sleeve to change the position of the oil detection element. S3, the cleaning agent spraying unit sprays the cleaning agent on the oily area, the servo motor starts, and the reciprocating screw and the rotating shaft body rotate under the action of the chain transmission mechanism. When the reciprocating screw rotates, the extension rod frame on it will perform lifting movement, and the extension rod frame will drive the connecting panel to move synchronously. The connecting panel will drive the connecting shaft body to drive the cleaning cotton cylinder to move synchronously through the hinged rod. The cleaning cotton cylinder contacts the surface of the steel structure. Due to the rotational connection between the hinged rod and the rotating panel, the cleaning cotton cylinder will perform a directional wiping action on the surface of the steel structure; S4. Under the action of the chain transmission mechanism, the rotating shaft body rotates synchronously with it, and the threaded groove body on the rotating shaft body acts on the telescopic shaft body, so that the sliding sleeve is lowered under the action of the telescopic shaft body, and the rubber scraper at the bottom of the sliding sleeve is synchronously lowered with it and contacts with the surface of the steel structure, and the rubber scraper removes the cleaning agent and absorbs the cleaning agent by the suction part on the rubber scraper; S5. The rolling ball will pass by the English label. If there is slag at the English label, the rolling ball will be affected by the slag and the retractable rod frame will adjust its position inside the support sleeve. During the position adjustment process, the retractable rod frame will act on the button. The button controls the electromagnet group 2 and the solenoid valve. The solenoid valve controls the outflow of the marking liquid in the tube body so that the marking liquid marks the slag area. When encountering an arc-shaped steel structure, the electromagnet group 2 can be controlled to be energized so that the electromagnet group 2 generates an attractive force on the magnetic surface of the moving mechanism, and the moving mechanism performs an upward motion to drive multiple support sleeves to perform synchronous upward motion, thereby changing the position of the retractable rod frame and the rolling ball.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes the cleaning part to spread and wipe the cleaning agent on the oily area, thereby achieving the purpose of cleaning the oily area. In order to prevent the cleaning agent from affecting the laser cutting work, the cleaning agent is also recovered by the cleaning agent collecting part.

[0015] The present invention utilizes a rolling ball to detect the slag condition of the English sign. The rolling ball will be affected by the slag to make the telescopic rod frame adjust its position inside the supporting sleeve. During the position adjustment process, the telescopic rod frame will act on a button. The button controls the electromagnet group 2 and the solenoid valve. The solenoid valve controls the outflow of the marking liquid in the tube body, so that the marking liquid marks the slag area, thereby facilitating the staff to subsequently handle the slag area.

[0016] The present invention utilizes a rubber scraper to remove the cleaning agent, and utilizes an air suction portion on the rubber scraper to absorb the cleaning agent, thereby preventing the cleaning agent from affecting the laser cutting work. BRIEF DESCRIPTION OF THE DRAWINGS

If there is oil stain in a local area of ​​the steel structure plate, the cleaning agent spraying unit 6 will spray the corresponding cleaning agent (such as gasoline, alcohol, etc., and be careful to avoid using solvents that may cause surface corrosion) to the area. Then the cleaning unit 7 will spread the cleaning agent in the area and wipe the oily area, so as to achieve the purpose of cleaning the oil stains. In order to avoid the cleaning agent from affecting the laser cutting work, the cleaning agent is also recovered by the cleaning agent collecting unit 8. Then the cutting machine 2 processes the English signboard on the steel structure, but the processed English signboard may still have slag due to other factors. In order to ensure the processing quality of the English signboard, the present invention also carries out the following designs: An annular sleeve 41 is also fixedly installed on the connecting portion 4, wherein a moving mechanism 42 is installed inside the annular sleeve 41 and is slidably connected to its inner wall, one end of the moving mechanism 42 is a magnetic surface, and the other end of the moving mechanism 42 penetrates the inner wall of the bottom of the annular sleeve 41 and extends to the outside, and an electric magnetic group 43 is fixedly installed on the inner wall of the top of the annular sleeve 41, and the electric magnetic group 43 is energized to generate an attractive force on the magnetic surface of the moving mechanism 42, and a spring body 44 is connected between the moving mechanism 42 and the bottom of the annular sleeve 41, wherein the end of the moving mechanism 42 located outside the annular sleeve 41 is installed with A plurality of support sleeves 45 are provided, each of which is provided with a retractable rod frame 46. One end of the retractable rod frame 46 passes through the support sleeve 45 and is provided with a rolling ball 47. The rolling ball 47 is fitted with the surface of the steel structure to detect the slag condition. A button 48 is also fixedly provided inside the support sleeve 45. The button 48 is located on the movement track of the retractable rod frame 46. A tube body 49 filled with a marking liquid is also fixedly provided on the support sleeve 45.

Figure 2 , Attachment Fig.11 , Attachment Fig.12 and attached Figure 3As shown, after the laser cutting of the cutting machine 2, the mechanical parts on the annular sleeve 41 will be inspected; and then when the English label is processed, the rolling ball 47 will pass by the English label. Assuming that there is slag at the English label, the rolling ball 47 will be affected by the slag so that the telescopic rod frame 46 will adjust its position inside the supporting sleeve 45. During the position adjustment process, the telescopic rod frame 46 will act on the button 48, and the button 48 controls the operation of the electric magnetic group 2 43 and the electromagnetic valve 40. It should be noted that the button 48 is electrically connected to the electric magnetic group 2 43, and the electromagnetic valve 40 controls the pipe body 4 9, the marking liquid in the marking device 42 flows out, so that the marking liquid marks the slag hanging area; when encountering an arc-shaped steel structure, in order to prevent the telescopic rod frame 46 and the rolling ball 47 from colliding with the surface of the arc-shaped steel structure, the electric magnetic group 43 can be controlled to be energized, so that the electric magnetic group 43 generates an attractive force on the magnetic surface of the moving mechanism 42, and the moving mechanism 42 performs an upward movement to drive the multiple support sleeves 45 to perform a synchronous upward movement, thereby changing the positions of the telescopic rod frame 46 and the rolling ball 47, thereby preventing the telescopic rod frame 46 and the rolling ball 47 from colliding with the surface of the raised area of ​​the arc-shaped steel structure; The oil stain detection part 5 includes a detection sleeve 51 fixedly mounted on the connecting part 4, and a detection rod frame 52 slidably connected to the inner wall of the detection sleeve 51 is installed inside the detection sleeve 51, wherein the end of the detection rod frame 52 passes through the inner wall at the bottom of the detection sleeve 51 and extends to the outside, and an oil stain detection element 53 is fixedly mounted on one end of the detection rod frame 52 located outside the detection sleeve 51. In the present invention, the oil stain detection element 53 is a non-contact oil stain detection probe, and the non-contact oil stain detection probe is a device that uses non-contact technology to detect oil stains. It can measure the presence and degree of oil stains through specific physical or chemical effects without directly contacting the object to be detected; an annular magnetic plate 54 is also fixedly mounted on one end of the detection rod frame 52 located inside the detection sleeve 51, and an electric magnetic group 55 is fixedly mounted on the inner wall of the top of the detection sleeve 51. When the electric magnetic group 55 is energized, it generates an attractive force on the annular magnetic plate 54, wherein the annular magnetic plate A return spring 56 is connected between 54 and the inner wall of the bottom of the detection sleeve 51, and a plurality of arc-shaped baffles 57 are arranged outside the oil detection element 53, and an extension shaft 58 is fixedly installed on the arc-shaped baffle 57, and one end of the extension shaft 58 is located inside the oil detection element 53 and is slidably connected thereto, and a spring mechanism 59 is connected between the arc-shaped baffle 57 and the outer wall of the oil detection element 53, and a sensing element 50 is also fixedly installed inside the oil detection element 53, and the sensing element 50 is located on the movement trajectory of the extension shaft 58, wherein the sensing element 50 is electrically connected to the electric magnetic group 1 55. It should be noted that under normal circumstances, the spring body 44 is in a compressed state, so that when there is a concave condition on the surface of the steel structure plate, under the action of the spring body 44, the moving mechanism 42 can drive the plurality of supporting sleeves 45 to descend, and then the telescopic rod frame 46 and the rolling ball 47 can always be in contact with the surface of the steel structure plate; In the actual production process, not all steel structure plates are flat. Occasionally, there are steel structure plates with curved surfaces. During the oil detection process on such steel structure plates, the surface of the oil detection element 53 is prone to collide with the upward protruding area of ​​the steel structure, which can easily cause damage to the oil detection element 53. When the present invention encounters this situation, the cutting machine 2 can drive the connecting part 4 to move synchronously by rotating the sleeve 3, and the detection sleeve 51 on the connecting part 4 moves synchronously with it. During the movement, the detection rod frame 52 drives the oil detection element 53 to move synchronously. The oil condition on the surface of the steel structure can be known through the oil detection element 53. When encountering an arc-shaped curve When the oil detection element 53 is close to the raised area of ​​the steel structure plate, the arc baffle 57 will first contact the raised area, and then the raised area of ​​the steel structure plate will first act on the arc baffle 57, and the arc baffle 57 is acted upon to make the extension shaft 58 move toward the inside of the oil detection element 53, the spring mechanism 59 is in a compressed state, and the induction element 50 is triggered, the electric magnetic group 1 55 is energized, and an attractive force is generated on the annular magnetic plate 54, so that the detection rod frame 52 performs a directional upward movement inside the detection sleeve 51, so as to change the position of the oil detection element 53, and avoid the oil detection element 53 from contacting and colliding with the arc raised area; As a further limitation of the present invention, the cleaning portion 7 includes a fixed sleeve 71 fixedly mounted on the connecting portion 4, and a connecting panel 72 is arranged below the fixed sleeve 71, and a plurality of rotating portions 73 rotatably connected thereto are installed on the connecting panel 72, a cleaning cotton cylinder 74 is installed on the rotating portion 73, and a transmission portion 75 for driving the lifting movement of the connecting panel 72 is arranged inside the fixed sleeve 71, the cleaning agent spraying portion 6 sprays the cleaning agent for cleaning the oil stains, and the connecting panel 72 acts on the transmission portion 75 The rotating part 73 drives the cleaning cotton cylinder 74 to spread the cleaning agent and treat the oil stains on the surface of the steel structure. The transmission part 75 includes a reciprocating screw rod 751 rotatably connected to the fixed sleeve 71, and one end of the reciprocating screw rod 751 is fixed to the top of the sleeve 71 and extends to the outside, wherein an extension rod frame 752 is installed on the reciprocating screw rod 751, and the end of the extension rod frame 752 passes through the inner wall of the bottom of the fixed sleeve 71, and the extension rod frame 752 is slidably connected to the inner wall of the fixed sleeve 71, and one end of the extension rod frame 752 is connected to the connecting The panel 72 is fixedly connected; the rotating part 73 is a hinged rod 731, and a connecting shaft 741 is fixedly installed on the top of the cleaning cotton cylinder 74, and the connecting shaft 741 is rollingly connected to the bottom of the hinged rod 731. A limiting sleeve 81 is also fixedly installed on the connecting part 4, and the limiting sleeve 81 and the fixed sleeve 71 are fixedly connected through a supporting plate frame 91. A rotating shaft 82 rotatably connected to the inner wall of the limiting sleeve 81 is installed inside the limiting sleeve 81, and the end of the rotating shaft 82 passes through the inner wall of the top of the limiting sleeve 81 and extends to the outside. The rotating shaft 82 is provided with a sliding sleeve 821 which is slidably connected with the inner wall of the limiting sleeve 81, wherein the rotating shaft 82 is provided with a threaded groove 83, an annular groove 84 and a guide plate frame 85, the annular groove 84 and the threaded groove 83 are in a communicating state, a telescopic shaft 822 is fixedly installed on the inner wall of the sliding sleeve 821, and the telescopic shaft 822 slides in the limit position of the annular groove 84 and the threaded groove 83, and the guide plate frame 85 is fixedly installed at the intersection of the annular groove 84 and the threaded groove 83, and the guide plate frame 85 is fixedly installed at the intersection of the annular groove 84 and the threaded groove 83. Fig. 9As shown, the side of the guide plate frame 85 located at the intersection of the threaded groove body 83 and the annular groove body 84 is a right-angled surface, and the side of the annular groove body 84 is an inclined surface, wherein a servo motor 9 is fixedly installed on the support plate frame 91, and the output end of the servo motor 9 is connected to the reciprocating screw rod 751 and the rotating shaft body 82 through a chain transmission mechanism 92. In the present invention, when the servo motor 9 rotates forward, the rotating shaft body 82 rotates forward synchronously with it. At this time, the telescopic shaft body 822 will contact the inclined surface of the guide plate frame 85 during the movement, and the telescopic shaft body 822 will shrink under the action of the inclined surface of the guide plate frame 85. When the servo motor 9 reverses, the telescopic shaft body 822 will enter the threaded groove body 83 along the trajectory of the annular groove body 84 under the action of the right-angled surface of the guide plate frame 85; wherein a rubber scraper 823 for concentrating the cleaning agent is fixedly installed at one end of the sliding sleeve 821, and an air suction part 824 is fixedly installed on the rubber scraper 823; During the actual processing, the forward position of the cutting machine 2 usually changes. In order to detect and process the oil pollution on the surface of the steel structure, the oil pollution detection part 5, the cleaning agent spraying part 6, the cleaning part 7, the cleaning agent collecting part 8 and the annular sleeve 41 in the present invention need to be replaced. In the present invention, a driving motor 21 is fixedly installed on the cutting machine 2, and a meshing gear 22 is fixedly installed on the output end of the driving motor 21, and an annular gear row 31 meshing with the meshing gear 22 is fixedly installed on the outer wall of the rotating sleeve 3. The meshing gear 22 is controlled to rotate by the driving motor 21, so that the meshing gear 22 meshes with the annular gear row 31 to drive the rotating sleeve 3 to rotate, thereby making the connecting part 4 on the rotating sleeve 3 perform corresponding position adjustment.

[0021] Step a: When processing the English sign of the steel structure, the cutting machine 2 is working. First, the oil stain detection element 53 detects the oil stain on the surface of the steel structure. If there is oil stain on the surface of the steel structure, the oil stain detection unit 5 will control the cleaning agent spraying unit 6 to work in the form of an electrical signal, so that the cleaning agent in the cleaning agent spraying unit 6 is sprayed onto the surface of the steel structure. If the surface of the steel structure is curved, then when the oil stain detection element 53 is close to the raised area of ​​the steel structure plate, the arc baffle 57 will first contact the raised area, and the steel structure will be cut. The raised area of ​​the structural plate will first act on the arc baffle 57, and the arc baffle 57 is acted upon so that the extension shaft 58 moves toward the inside of the oil detection element 53, the spring mechanism 59 is in a compressed state, and the sensing element 50 is triggered, the electric magnetic group 1 55 is energized, and an attractive force is generated on the annular magnetic plate 54, so that the detection rod frame 52 performs a directional upward movement inside the detection sleeve 51, so as to change the position of the oil detection element 53, and prevent the oil detection element 53 from contacting and colliding with the arc raised area; Step b: After the cleaning agent is sprayed, the servo motor 9 is started, and the reciprocating screw rod 751 and the rotating shaft 82 are rotated under the action of the chain transmission mechanism 92. When the reciprocating screw rod 751 rotates, the extension rod frame 752 thereon will perform a lifting movement. In the present invention, in the initial state, the extension rod frame 752 performs a descending movement. When descending, the extension rod frame 752 will drive the connecting panel 72 to move synchronously, and the connecting panel 72 will drive the connecting shaft 741 to drive the cleaning cotton cylinder 74 to descend synchronously through the hinged rod 731. Due to the rotational connection between the hinged rod 731 and the connecting panel 72, the cleaning cotton cylinder 74 contacts the surface of the steel structure during the descent process. Due to the rotational connection between the hinged rod 731 and the rotating panel, the cleaning cotton cylinder 74 will wipe the surface of the steel structure, and the connecting shaft 741 is rollingly connected to the bottom of the hinged rod 731 (combined with the attached Figure 7 As shown), when the cleaning cotton cylinder 74 moves to the area with less friction on the surface of the steel structure, the cleaning cotton cylinder 74 will rotate with the axis of the connecting shaft 741 as the center line, so that the cleaning cotton cylinder 74 changes its angle, increasing the randomness during cleaning, improving the efficiency and quality of oil stain treatment, so that the oil stain on the surface of the steel structure can be effectively treated under the action of the cleaning cotton cylinder 74 and the cleaning agent; Step c: When the servo motor 9 is started, the rotating shaft 82 is synchronously rotated with it under the action of the chain transmission mechanism 92, and the threaded groove 83 on the rotating shaft 82 acts on the telescopic shaft 822, so that the sliding sleeve 821 is lowered under the action of the telescopic shaft 822, and the rubber scraper 823 at the bottom of the sliding sleeve 821 is synchronously lowered with it and contacts the surface of the steel structure. When the rubber scraper 823 contacts the surface of the steel structure, the telescopic shaft 822 is in the annular groove 84. In this process, the telescopic shaft 822 enters the annular groove through the right angle surface of the guide plate frame 85. In the annular groove 84, the servo motor 9 rotates forward, and the telescopic shaft 822 contacts the inclined surface of the guide plate frame 85 during the movement. Under the action of the inclined surface of the guide plate frame 85, the telescopic shaft 822 is retracted. When the servo motor 9 rotates reversely, the telescopic shaft 822 enters the threaded groove 83 along the trajectory of the annular groove 84 under the action of the right-angled surface of the guide plate frame 85, and finally reaches the initial end of the threaded groove 83. When the telescopic shaft 822 is at the initial end of the threaded groove 83, the extension rod frame 752 also moves to the initial position, that is, the cleaning cotton cylinder 74 and the rubber scraper 823 do not contact the surface of the steel structure. When the rubber scraper 823 contacts the surface of the steel structure, the rubber scraper 823 will scrape off the cleaning agent, and use the suction part 824 on the rubber scraper 823 to absorb the cleaning agent to avoid the cleaning agent from affecting the laser cutting work. After the English sign is processed, the rolling ball 47 will pass through the English sign. If there is slag at the English sign, the rolling ball 47 will be affected by the slag and make the telescopic rod frame 46 adjust its position inside the support sleeve 45. During the position adjustment process, the telescopic rod frame 46 will act on the button 48, and the button 48 controls the electromagnet group 43 and the solenoid valve 40. The solenoid valve 40 controls the outflow of the marking liquid in the tube 49, so that the marking liquid marks the slag area. An operating method of a laser cutting device for processing English signboards on steel structures specifically comprises the following steps: S1, the cutting machine 2 processes the English label on the steel structure on the machine tool 1. First, the cutting machine 2 drives the connecting part 4 to move synchronously by rotating the sleeve 3, and the detection sleeve 51 on the connecting part 4 moves synchronously with it. During the movement, the detection rod frame 52 drives the oil detection element 53 to move synchronously, and the oil pollution condition on the surface of the steel structure can be known through the oil pollution detection element 53; S2. When encountering an arc-shaped curved steel structure plate, the arc baffle 57 will first contact the raised area, and then the raised area of ​​the steel structure plate will first act on the arc baffle 57. The arc baffle 57 is acted upon by a force so that the extension shaft 58 moves toward the inside of the oil detection element 53. The sensing element 50 is triggered, and the electric magnetic group 1 55 is energized to generate an attractive force on the annular magnetic plate 54, so that the detection rod frame 52 performs a directional upward movement inside the detection sleeve 51 to change the position of the oil detection element 53. S3, the cleaning agent spraying unit 6 sprays the cleaning agent on the oily area, the servo motor 9 is started, and the reciprocating screw 751 and the rotating shaft 82 are rotated under the action of the chain transmission mechanism 92. When the reciprocating screw 751 rotates, the extension rod frame 752 thereon will perform a lifting movement, and the extension rod frame 752 will drive the connecting panel 72 to move synchronously. The connecting panel 72 will drive the connecting shaft 741 to drive the cleaning cotton cylinder 74 to move synchronously through the hinged rod 731. The cleaning cotton cylinder 74 contacts the surface of the steel structure. Due to the rotational connection between the hinged rod 731 and the rotating panel, the cleaning cotton cylinder 74 will perform a directional wiping action on the surface of the steel structure; S4. Under the action of the chain transmission mechanism 92, the rotating shaft 82 rotates synchronously therewith, and the threaded groove 83 on the rotating shaft 82 acts on the telescopic shaft 822, so that the sliding sleeve 821 descends under the action of the telescopic shaft 822, and the rubber scraper 823 at the bottom of the sliding sleeve 821 descends synchronously therewith and contacts with the surface of the steel structure, and the rubber scraper 823 removes the cleaning agent, and uses the suction part 824 on the rubber scraper 823 to absorb the cleaning agent; S5. The rolling ball 47 will pass by the English label. If there is slag at the English label, the rolling ball 47 will be affected by the slag and the telescopic rod frame 46 will be adjusted in position inside the support sleeve 45. During the position adjustment process, the telescopic rod frame 46 will act on the button 48. The button 48 controls the electromagnet group 2 43 and the solenoid valve 40. The solenoid valve 40 controls the outflow of the marking liquid in the tube 49 so that the marking liquid marks the slag area. When encountering an arc-shaped steel structure, the electromagnet group 2 43 can be controlled to be energized so that the electromagnet group 2 43 generates an attractive force on the magnetic surface of the moving mechanism 42, and the moving mechanism 42 performs an upward movement to drive multiple support sleeves 45 to perform synchronous upward movement, thereby changing the position of the telescopic rod frame 46 and the rolling ball 47.
