Description

Technical Field

[0001] This invention relates to the field of slag removal technology for sheet metal coating, and in particular to an automatic slag removal device for sheet metal coating processes used in new energy vehicles. Background Technology

[0002] Hot-dip galvanized steel sheets are widely used in the bodies of new energy vehicles. The production process includes ironmaking, steelmaking, hot rolling, pickling, cold rolling, followed by annealing and continuous hot-dip galvanizing or alloying treatment to ultimately produce various automotive steel sheet products. However, residual iron powder on the surface of the steel strip during galvanizing reacts with molten zinc to form Fe-Zn intermetallic compounds (zinc slag), severely affecting coating quality, causing surface defects, and increasing zinc consumption costs. Due to space limitations in the zinc pot, manual slag removal is still the primary method, posing multiple risks: splashing of high-temperature molten metal can easily cause burns; zinc oxide aerosols volatilized at 580-610℃ are harmful to human health; and the efficiency and cleanliness of manual slag removal are unstable, easily leading to defects such as pinholes and slag marks in the coating, reducing product qualification rates and increasing production costs.

[0003] In existing technologies, there are several solutions for slag removal from hot-dip galvanized zinc pots. One method uses a slag-scraping plate structure, where a first slag-scraping plate scrapes the zinc slag to both sides, and a second slag-scraping plate removes it along the length. However, this structure is difficult to adjust, and improper amplitude control can cause the zinc slag to drift with the molten zinc, making automated operation challenging. Other robotic slag-removing devices employ either dual-guide-cylinder clamping or tail-mounted dual-claw gripping, automatically changing slag-removing tools according to site conditions, effectively reducing manual workload. However, these designs primarily focus on the clamping structure and automatic tool changing, without addressing the overall solution for automatically removing floating zinc slag from the zinc pot. Another method uses a centrifugal slag-suction cylinder in conjunction with a slag-removing robot, operating in tandem with the suction robot. This achieves online slag removal through centrifugal suction, slag removal, and slag discharge cycles, reducing the entrainment of metallic zinc in the slag. However, because molten zinc is temperature-sensitive at high temperatures, temperature fluctuations below the melting point can cause the molten zinc and zinc slag to solidify and clog the pump, resulting in low efficiency.

[0004] To address this, an automatic slag removal device for the coating process of sheet metal for new energy vehicles is proposed. Summary of the Invention

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-8 This invention provides an automatic slag removal device for the coating process of sheet metal for new energy vehicles, comprising: A worktable base, on which a driven turntable 203 is rotatably connected; A rotary drive mechanism is mounted on the worktable base and is used to drive the driven turntable 203 to rotate. The radial movement mechanism includes a radial translation component and a tilt drive component. The radial translation component is mounted on the driven turntable 203, and the tilt drive component is mounted on the moving end of the radial translation component. The slag removal mechanism includes a self-heating trough assembly and an automatic scooping bucket assembly; the self-heating trough assembly is installed at the output end of the tilting drive assembly, and the automatic scooping bucket assembly is installed at one end of the self-heating trough assembly. The zinc slag recycling mechanism is located at the end of the self-heating trough assembly away from the automatic scoop assembly, and a heating element is installed inside the zinc slag recycling mechanism. With this configuration, the present invention achieves fully automated slag removal from the zinc molten metal surface through the coordinated operation of the rotary drive mechanism, radial movement mechanism, slag removal mechanism, and zinc slag recovery mechanism, eliminating the need for manual slag removal. The rotary drive mechanism drives the driven turntable 203 to rotate, which in turn drives the radial movement mechanism and slag removal mechanism to rotate synchronously, achieving full coverage slag removal in the zinc pot. The radial translation component can drive the slag removal mechanism to move radially, and the tilt drive component can adjust the tilt angle of the self-heating material tank component, adjust the posture of the automatic slag removal bucket component, and quickly guide the zinc slag removed by the automatic slag removal bucket component into the zinc slag recovery mechanism. Compared with traditional manual slag removal, this invention significantly improves slag removal efficiency, completely frees up manpower, reduces the labor intensity of operators, avoids direct contact between operators and high-temperature zinc molten metal, and improves operational safety. This invention uses a self-heating feed tank assembly to heat and keep the collected zinc dross warm, preventing the zinc dross from cooling, clumping, and sticking to the feed tank or hopper, ensuring smooth transport of the zinc dross. The automatic hopper assembly can accurately remove the floating dross from the surface of the zinc liquid. With the precise control of the rotary drive mechanism and the radial movement mechanism, it can achieve all-round, no-dead-angle removal of zinc dross from the surface of the zinc liquid, avoiding excessive accumulation of zinc dross that sticks to the coating surface of the sheet metal. This effectively reduces coating defects, bubbles, inclusions, and other quality problems, improves the smoothness, density, and gloss of the coating surface of the sheet metal used in new energy vehicles, and ensures that the coating quality of the sheet metal meets the requirements. This invention uses heating elements installed within the recycling mechanism to keep zinc dross warm, preventing it from cooling and solidifying. This facilitates the secondary recycling of zinc dross, reduces waste of zinc resources, and lowers the raw material costs of sheet coating production. This invention can efficiently and accurately remove dross from the zinc bath surface, greatly improving the dross removal efficiency in the zinc pot, reducing labor intensity, increasing production efficiency, and preventing excessive zinc dross from adhering to the sheet coating, thereby reducing the quality of the sheet coating.

[0023] The zinc slag recycling mechanism has been further optimized, including a slag collection trough 501, a hydraulic jack assembly 502, and a zinc slag recycling tank 503. The hydraulic jacking rod assembly 502 is mounted on the radial translation assembly. The outer wall of the slag collection trough 501 is rotatably connected to the radial translation assembly through the first rotating shaft. The bottom surface of the slag collection trough 501 is slidably connected to the first slider. The telescopic end of the hydraulic jacking rod assembly 502 is hinged to the first slider. The slag collection trough 501 is located at the end of the self-heating material trough assembly away from the automatic scooping bucket assembly. The heating element is installed at the bottom of the slag collection trough 501. The zinc slag recovery tank 503 is installed on the workbench base. The slag collection trough 501 is equipped with a guide port, which faces the zinc slag recovery tank 503. When the zinc dross accumulates to a certain amount in the dross collection trough 501, the hydraulic jack assembly 502 extends and retracts, pushing the first slider to slide and causing the dross collection trough 501 to rotate around the first rotating shaft, adjusting the tilt angle of the dross collection trough 501 to facilitate the introduction of zinc dross into the zinc dross recovery tank 503. Heating elements are installed at the bottom of the dross collection trough 501 to continuously heat and keep the falling zinc dross warm, preventing it from cooling and clumping, and avoiding blockage of the conveying channel.

[0024] Further optimization of the scheme includes the following radial translation components: The chassis 301 is mounted on the driven turntable 203, and the outer wall of the slag collection tank 501 is rotatably connected to the outer wall of the chassis 301 through the first rotating shaft. Parallel guide rail 302 is mounted on the inner wall of chassis 301; A double-stage telescopic hydraulic cylinder 303 is mounted on the outer wall of the housing 301 via a bracket. The piston end of the double-stage telescopic hydraulic cylinder 303 is equipped with a first-stage hydraulic guide rod 304 and a second-stage hydraulic guide rod 305. The first-stage hydraulic guide rod 304 is positioned close to the double-stage telescopic hydraulic cylinder 303. A hydraulic push rod assembly 502 is mounted on the bracket. The column-carrying slide plate 306 is installed at one end of the secondary hydraulic guide rod 305. The column-carrying slide plate 306 is slidably connected to the parallel guide rail 302. The tilting drive assembly is installed on the column-carrying slide plate 306. During operation, the dual-stage telescopic hydraulic cylinder 303 is activated, driving the first-stage hydraulic guide rod 304 and the second-stage hydraulic guide rod 305 to extend and retract in stages, pushing the carrier plate 306 to slide smoothly along the parallel guide rail 302, thereby driving the tilting drive component and the slag removal mechanism to move radially. The slag removal position can be precisely adjusted according to the size of the zinc pot and the distribution of zinc slag, achieving slag removal without dead angles in the radial entire area of ​​the zinc pot. At the same time, the staged telescopic structure can flexibly control the moving distance, improving the adjustment accuracy and stability.

[0025] Further optimization of the scheme: the tilting drive component includes a first hydraulic lifting column 307 and a second hydraulic lifting column 308; the first hydraulic lifting column 307 and the second hydraulic lifting column 308 are installed side by side on the column-carrying slide plate 306; the piston end of the first hydraulic lifting column 307 is hinged to the bottom surface of the self-heating material tank assembly; the piston end of the second hydraulic lifting column 308 is hinged to a trapezoidal slider 407; the trapezoidal slider 407 is slidably connected to the bottom surface of the self-heating material tank assembly. The first hydraulic lifting column 307 and the second hydraulic lifting column 308 extend and retract independently. By sliding the trapezoidal slider 407 on the bottom surface of the self-heating trough assembly, the tilt angle of the self-heating trough assembly can be flexibly adjusted, the posture of the automatic scooping bucket assembly can be adjusted, and the zinc slag can be smoothly slid into the slag collection tank 501 under the action of gravity, so as to avoid the zinc slag from accumulating in the trough and improve the slag removal efficiency.

[0026] Further optimization of the design includes the following self-heating feed tank assembly: The insulation tank 408 has a trapezoidal guide rail 406 installed on its bottom surface. The trapezoidal slider 407 is slidably connected to the trapezoidal guide rail 406. The piston end of the first hydraulic lifting column 307 is hinged to the bottom surface of the insulation tank 408. The top cover 410 of the heat insulation tank has two side wings installed on both sides of its top surface. The top cover 410 of the heat insulation tank is installed on the top surface of the heat insulation tank 408. The first heating coil 409 is installed on the bottom wall of the heat preservation tank 408. The automatic scooping bucket assembly is installed at one end of the insulation tank 408, and the slag collection tank 501 is located at the end of the insulation tank 408 away from the automatic scooping bucket assembly. The two insulation tank covers 410 effectively reduce heat loss within the insulation tank 408, improving insulation performance while preventing zinc dross from splashing and contaminating the production environment. The first heating coil 409 is continuously energized during operation, heating and maintaining the zinc dross falling into the insulation tank 408. This keeps the zinc dross temperature within a reasonable range, preventing it from cooling, solidifying, or clumping and adhering to the inner wall of the insulation tank 408 or the automatic scoop assembly.

[0027] Further optimization of the solution includes the following automatic scooping bucket components: Hydraulic cylinder 405 is installed on the bottom surface of the heat preservation tank 408, and hydraulic push rod 404 is installed on the piston end of hydraulic cylinder 405. Crank 402 is connected to hydraulic push rod 404 via connecting rod 403; The bucket body 401 has a crank 402 mounted on one end away from the connecting rod 403. The bucket body 401 is rotatably connected to the heat preservation tank 408 via a second rotating shaft. An arc-shaped leak is installed on one end of the bucket body 401 near the heat preservation tank 408. An arc-shaped leak is provided on the side of the heat preservation tank 408 away from the bucket body 401, and an arc-shaped leak is provided at the end of the bucket body 401. During operation, hydraulic cylinder 405 is activated, pushing hydraulic push rod 404 to extend and retract. This, via connecting rod 403, drives crank 402 to rotate around the second shaft, thereby causing the bucket body 401 to flip up and down. When the bucket body 401 flips downward, it precisely fits against the surface of the molten zinc, scooping up the slag on the surface. After scooping, hydraulic cylinder 405 extends and retracts in the opposite direction, causing the bucket body 401 to flip upward. When it flips to the appropriate angle, the zinc slag inside the bucket body 401 falls smoothly into the insulation tank 408 through the arc-shaped nozzle, achieving precise slag scooping and conveying. The structure is flexible, the scooping efficiency is high, and the drawbacks of manual slag scooping are avoided.

[0028] The scheme is further optimized. The rotary drive mechanism includes a rotary drive motor 201 mounted on the workbench base. A drive gear 202 is mounted on the output shaft of the rotary drive motor 201. A gear ring is mounted on the outer side wall of the driven turntable 203. The gear ring meshes with the drive gear 202 for transmission. After the operation is started, the rotary drive motor 201 is powered on and runs, driving the drive gear 202 to rotate at a constant speed. Through gear meshing, the driven turntable 203 is driven to rotate smoothly on the annular track 101 of the workbench base. The speed can be precisely adjusted according to the slag removal requirements. When the driven turntable 203 rotates, it drives the radial moving mechanism, tilting drive assembly, slag removal mechanism and zinc slag recovery mechanism installed on it to rotate synchronously, so that the slag removal mechanism rotates around the center of the zinc pot, covering the entire area of ​​the zinc pot and avoiding dead corners in slag removal.

[0029] The scheme is further optimized. The workbench base includes a support plate 102, on which a ring track 101 is installed. The driven turntable 203 is rotatably connected to the ring track 101, and the zinc slag recovery tank 503 is installed on the support plate 102. The annular track 101 provides stable rotational support for the driven turntable 203, reducing friction during rotation and ensuring smooth, uniform rotation. This prevents jamming and misalignment, ensuring the stability of synchronous rotation of all mechanisms. The zinc slag recovery tank 503 is fixedly mounted on the support plate 102, precisely aligned with the feed inlet of the slag collection trough 501. This ensures that the zinc slag discharged from the slag collection trough 501 falls accurately into the recovery tank, achieving centralized collection of zinc slag.

[0030] The design is further optimized by using a second heating coil 504 as the heating element. When the zinc slag conveyed by the self-heating trough assembly falls into the slag collection trough 501, the second heating coil 504 is energized and heats up, continuously heating and keeping the zinc slag in the slag collection trough 501 at a molten state. This prevents the zinc slag from cooling, solidifying, and clumping onto the inner wall of the slag collection trough 501, thus avoiding blockage of the feed inlet and ensuring that the zinc slag can be smoothly discharged into the zinc slag recovery tank 503.

[0031] The design was further optimized by mounting the chassis 301 on the driven turntable 203 with several bolts, ensuring that the radial translation component is firmly connected to the driven turntable 203 and moves synchronously, thereby improving the stability and reliability of the device operation and facilitating later maintenance and repair.

[0032] The working principle of this invention is as follows: I. Preparation Status First, start the slag removal device and set it to its initial position, which is the location of the zinc slag recovery tank 503 on the edge of the zinc pot. At the same time, the hydraulic push rod assembly 502 pulls the slag collection trough 501 to a horizontal position. Determine the area where the zinc slag accumulates in the zinc pot. Then, use the rotary drive motor 201 to drive the driven turntable 203 to move the machine box 301 in a circular motion along the zinc pot, so that the machine box 301 is directly in front of the area where the zinc slag accumulates. Then, stop the rotary drive motor 201 and simultaneously start the first heating coil 409 in the heat preservation tank 408 and the second heating coil 504 in the slag collection trough 501 in the slag removal device to preheat the corresponding areas.

[0033] II. Zinc dross retrieval status First, the first-stage hydraulic guide rod 304 and the second-stage hydraulic guide rod 305 of the double-stage telescopic hydraulic cylinder 303 within the parallel guide rail 302 of the radial movement mechanism propel the entire slag removal device forward in a straight line along the parallel guide rail 302, causing the slag bucket to approach the target zinc slag accumulation area along the target direction. Then, the first hydraulic lifting column 307 within the parallel guide rail 302 lowers and the second hydraulic lifting column 308 rises, bringing the slag bucket body 401 closer to the target zinc slag accumulation area. Next, the hydraulic cylinder 405 drives the hydraulic push rod 404 to rotate the crank 402 in a linear motion, thereby causing the slag bucket body 401 to flip outward, achieving slag removal posture control of the slag bucket body 401 and obtaining the zinc slag floating on the liquid surface with a better slag removal posture. Once the scooping bucket enters the zinc molten liquid, the hydraulic cylinder 405 drives the scooping bucket body 401 to rotate inward again, thereby controlling the slag collection posture of the scooping bucket body 401 to detach from the zinc molten liquid in a better posture and ensure that the collected zinc slag does not overflow.

[0034] III. Zinc slag recovery status After the slag scooping bucket 401 scoops up the zinc slag, the first-stage hydraulic guide rod 304 and the second-stage hydraulic guide rod 305 of the double-stage telescopic hydraulic cylinder 303 in the parallel guide rail 302 push the entire slag scooping device to make a return linear motion along the parallel guide rail 302, thereby realizing the transfer of the zinc slag in the slag scooping bucket 401. When the transfer is close to the slag collection tank 501, the first hydraulic lifting column 307 in the parallel guide rail 302 performs an upward action and the second hydraulic lifting column 308 performs a downward action, so that the heat preservation tank 408 located above the slag scooping mechanism tilts towards the slag collection tank 501. Thus, the zinc slag in the slag scooping bucket 401 flows to the slag collection tank 501 through the arc-shaped nozzle and the heat preservation tank 408 under the action of gravity, and is temporarily stored in the slag collection tank 501.

[0035] When the slag collection trough 501 is full, the rotary drive motor 201 is started, causing the device to return to its initial position. At this time, the hydraulic cylinder 405 located below the slag collection trough 501 is started to rise, pushing the slag collection trough 501 to rotate towards the zinc slag recovery tank 503. The zinc slag falls into the zinc slag recovery tank 503, thereby realizing the recovery of zinc slag.
