Technical Field
[0001] This utility model belongs to the field of hot-dip galvanizing technology, and in particular relates to a novel robotic hot-dip galvanizing device. Background Technology
[0002] Hot-dip galvanizing is a surface treatment process in which a metal workpiece is immersed in molten zinc to form a zinc layer. This process not only creates a strong alloy layer between the steel substrate and the zinc coating, but also ensures a good bond between the iron and the pure zinc layer. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and long service life.
[0003] Chinese utility model patent CN221501207U discloses a hot-dip galvanizing device that can not only fix steel pipes of different lengths, but is also safer.
[0004] A search revealed that the hot-dip galvanizing equipment proposed in the aforementioned comparative documents still has some defects and shortcomings in practical use: it can only hot-dip galvanize a single steel pipe at a time, resulting in low efficiency; moreover, excess zinc remains on the surface of the steel pipe after it is lifted from the galvanizing bath, and slag and impurities appear on the surface of the galvanizing bath, which significantly affects the galvanizing quality. Therefore, there is an urgent need to improve the existing hot-dip galvanizing equipment and provide a new type of robotic hot-dip galvanizing device. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a novel robotic hot-dip galvanizing device that is reasonably designed, simple in structure, and has high galvanizing efficiency and quality, thereby solving the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel robotic hot-dip galvanizing device includes a galvanizing tank, a controller, a galvanizing robotic arm, and positioning rods. The controller is fixedly installed at the front left of the galvanizing tank, and a cleaning component is provided at the right end of the galvanizing tank. The galvanizing robotic arm is located behind the galvanizing tank and is equipped with a vibration component. A mounting plate is located directly below the vibration component. Vertical shafts are symmetrically arranged on the upper surface of the mounting plate. A servo motor is fixedly installed on the outer left side of the mounting plate. A sliding groove is formed in the middle of the bottom surface of the mounting plate. A bidirectional lead screw is mounted on a bearing in the sliding groove. The left end of the bidirectional lead screw is fixedly connected to the output shaft of the servo motor. Clamping rods are threaded onto both ends of the bidirectional lead screw. The top ends of the two clamping rods are engaged and slidably located within the sliding groove. The cleaning component, the galvanizing robotic arm, the vibration component, and the servo motor are all electrically connected to the controller via connecting wires.
[0008] In a preferred embodiment, the impurity removal assembly includes an electric slide rail, an electric slider, a fixing block, a positioning bolt, a support rod, and a scraper. The electric slide rail is fixedly installed on the outer wall of the top rear of the galvanizing tank. An electric slider is slidably fitted onto the outer side of the electric slide rail. A fixing block is fixed to the outer wall of the rear end of the electric slider. A positioning bolt is threaded to the middle of the outer wall of the fixing block. A support rod is provided on the upper right side of the galvanizing tank. The support rod includes a vertical section and a horizontal section. A scraper is fixedly connected to the lower part of the horizontal section.
[0009] In a preferred embodiment, the vertical section of the support rod is slidably connected to the fixing block, and the length of the scraper is less than the internal width of the galvanizing tank.
[0010] In a preferred embodiment, the vibration assembly includes a housing, a drive motor, a disc, a protruding post, and a T-shaped rod. The housing is fixedly mounted on a galvanized robotic arm. The drive motor is fixedly mounted on the inner wall of the housing. The output end of the drive motor is fixedly connected to the disc. A protruding post is fixedly provided at the outer edge of the front end face of the disc. A T-shaped rod is provided on the outer side of the protruding post. The bottom end of the T-shaped rod is welded and fixed to the mounting plate.
[0011] In a preferred embodiment, the outer walls of the left and right sides of the housing are symmetrically provided with protrusions, and the two protrusions are slidably sleeved on the outside of the two vertical shafts respectively.
[0012] In a preferred embodiment, a through groove structure is provided inside the top end of the T-shaped rod, and the end of the protrusion away from the disk is guided and slidably located in the through groove structure at the top of the T-shaped rod.
[0013] In a preferred embodiment, multiple positioning rods are fixed at equal intervals along the horizontal direction on the sides of the bottom of the two clamping rods that are close to each other, and the sliding directions of the two clamping rods are always opposite.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In the solution of this utility model:
[0016] When slag and impurities appear on the surface of the zinc liquid in the galvanizing bath, the electric slide rail can control the electric slider to drive the fixed block, support rod and scraper to move slowly and uniformly to the left. This pushes the slag and impurity layer to the left side of the galvanizing bath, making it easy to remove with existing tools, exposing the pure zinc liquid and avoiding affecting the quality of hot-dip galvanizing. In addition, the fixed block and support rod are slidably connected and the support rod is positioned by the positioning bolts, which makes it easy to adjust the height of the scraper and facilitate the pushing and cleaning of slag and impurities on the surface of the zinc liquid.
[0017] The two clamping rods are controlled by a two-way lead screw to move in opposite directions, facilitating hot-dip galvanizing of steel pipes of different lengths. Multiple positioning rods are fixed at equal intervals at the bottom of the clamping rods, allowing for simultaneous hot-dip galvanizing of multiple steel pipes, resulting in higher galvanizing efficiency and faster speed. Furthermore, when the steel pipe is raised after galvanizing, the drive motor can be activated to control the rotation of the disc and the convex column. The convex column can press against the T-shaped rod, causing the T-shaped rod to drive the mounting plate and clamping rods to stably reciprocate in small amplitudes under the action of the vertical axis, generating a vibration effect. This helps to shake off excess molten zinc from the surface of the steel pipe, saving materials and achieving cost savings. Attached Figure Description

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:
[0027] like Figure 1-5As shown, this utility model discloses a novel robotic hot-dip galvanizing device, which includes a galvanizing tank 1, a controller 2, a galvanizing robotic arm 4, and a positioning rod 12. The controller 2 is fixedly installed at the front left of the galvanizing tank 1. A cleaning component 3 is provided at the right end of the galvanizing tank 1. The galvanizing robotic arm 4 is located behind the galvanizing tank 1. A vibration component 5 is installed on the galvanizing robotic arm 4. A mounting plate 6 is provided directly below the vibration component 5. Vertical shafts 7 are symmetrically arranged on the upper surface of the mounting plate 6. A servo motor 8 is fixedly installed on the outer left side of the mounting plate 6. A sliding groove 9 is opened in the middle of the bottom surface of the mounting plate 6. A bidirectional lead screw 10 is installed in the sliding groove 9. The left end of the bidirectional lead screw 10 is fixedly connected to the output shaft of the servo motor 8. Both ends of the bidirectional lead screw 10 are threaded with clamping rods 11. The top ends of the two clamping rods 11 are engaged and slidably located in the sliding groove 9. The cleaning component 3, the galvanizing robotic arm 4, the vibration component 5, and the servo motor 8 are all electrically connected to the controller 2 through connecting wires.
[0028] Based on the above structure, the impurity removal component 3 includes an electric slide rail 31, an electric slider 32, a fixing block 33, a positioning bolt 34, a support rod 35, and a scraper 36. The electric slide rail 31 is fixedly installed on the outer wall of the top rear of the galvanizing tank 1. The electric slider 32 is engaged and slidably sleeved on the outer side of the electric slide rail 31. The fixing block 33 is fixed on the outer wall of the rear end of the electric slider 32. The positioning bolt 34 is threadedly connected to the middle of the outer wall of the fixing block 33. The support rod 35 is provided on the upper right side of the galvanizing tank 1. The support rod 35 includes a vertical section and a horizontal section. The scraper 36 is fixedly connected to the lower part of its horizontal section.
[0029] Based on the above structure, the vertical section of the support rod 35 is slidably connected to the fixing block 33, and the length of the scraper 36 is less than the internal width of the galvanizing tank 1.
[0030] In this embodiment, the electric slider 32 is slowly and uniformly moved to the left by the electric slide rail 31, so that the slag and impurity layer can be pushed to the left side of the galvanizing pool 1 by the scraper 36, and can be removed with existing tools, so as to expose the pure zinc liquid and avoid affecting the quality of hot-dip galvanizing.
[0031] Based on the above structure, the vibration assembly 5 includes a housing 51, a drive motor 52, a disc 53, a protruding post 54, and a T-shaped rod 55. The housing 51 is fixedly mounted on the galvanized robotic arm 4. The drive motor 52 is fixedly mounted on the inner wall of the housing 51. The output end of the drive motor 52 is fixedly connected to the disc 53. The protruding post 54 is fixedly provided at the outer edge of the front end face of the disc 53. The T-shaped rod 55 is provided on the outer side of the protruding post 54. The bottom end of the T-shaped rod 55 is welded and fixed to the mounting plate 6.
[0032] Based on the above structure, the outer walls of the left and right sides of the shell 51 are symmetrically provided with protrusions, and the two protrusions are slidably sleeved on the outside of the two vertical shafts 7 respectively.
[0033] In this embodiment, the vertical shaft 7 is used to improve the stability of the mounting plate 6 during small-amplitude lifting and vibration caused by the T-shaped rod 55.
[0034] Based on the above structure, a through groove structure is provided inside the top of the T-shaped rod 55, and the end of the protruding post 54 away from the disk 53 is guided and slidably located in the through groove structure at the top of the T-shaped rod 55.
[0035] In this embodiment, when the drive motor 52 is started to control the rotation of the disc 53 and the protruding post 54, the protruding post 54 can squeeze the T-shaped rod 55 with a through groove structure on the top, so that the T-shaped rod 55 can drive the mounting plate 6 and the clamping rod 11 to move up and down steadily in a small amplitude, producing a vibration effect, which makes it easier to shake off the excess zinc liquid on the surface of the steel pipe.
[0036] Based on the above structure, multiple positioning rods 12 are fixed at equal intervals along the horizontal direction on the side of the bottom of the two clamping rods 11 that are close to each other, and the sliding directions of the two clamping rods 11 are always opposite.
[0037] In this embodiment, the two clamping rods 11 are controlled to move in opposite directions by the bidirectional lead screw 10, which facilitates the clamping of steel pipes of different lengths. Furthermore, multiple positioning rods 12 are fixed at equal intervals at the bottom of the clamping rods 11, which facilitates the simultaneous hot-dip galvanizing of multiple steel pipes, resulting in higher galvanizing efficiency and faster speed.
[0038] The working principle of this utility model is as follows:
[0039] In use, multiple positioning rods 12, which are equidistantly arranged at the bottom of clamping rod 11, are used to install multiple steel pipes to be galvanized in sequence. The servo motor 8 is started to control the rotation of the bidirectional lead screw 10, which drives the two clamping rods 11 to move in opposite directions and move closer to each other, so that the steel pipes can be stably clamped. Then, the galvanizing robotic arm 4 is used to control the clamping rods 11 to send the steel pipes into the galvanizing bath 1 and make the steel pipes completely immersed in the zinc liquid for galvanizing. When the galvanizing is completed and the steel pipes are lifted, the drive motor 52 can also be started to control the rotation of the disc 53 and the protruding column 54. When the protruding column 54 rotates, it can squeeze the T-shaped rod 55, which has a through groove structure at the top, so that the T-shaped rod 55 drives the mounting plate 6 and the clamping rod 11 to stably reciprocate with small amplitudes under the action of the vertical shaft 7, which can produce a vibration effect, so as to shake off the excess zinc liquid on the surface of the steel pipe, thereby achieving the purpose of saving materials and saving costs.
[0040] When slag and impurities appear on the surface of the zinc liquid in the galvanizing tank 1, the electric slider 32 can be slowly and uniformly moved to the left by the electric slide rail 31. The slag and impurity layer can be pushed to the left side of the galvanizing tank 1 by the scraper 36, and then removed and cleaned with existing tools. This makes it easy to expose the pure zinc liquid and avoid affecting the quality of hot-dip galvanizing. In addition, the fixing block 33 and the support rod 35 are slidably connected, and the positioning bolt 34 makes it easy to position the support rod 35 against the ground. This makes it easy to adjust the height of the scraper 36 and push and clean the slag and impurities on the surface of the zinc liquid.
[0041] It should be noted that the galvanizing tank 1, controller 2, electric slide rail 31, electric slider 32, galvanizing robotic arm 4, drive motor 52 and servo motor 8 are all existing products and equipment, powered by an external power supply. Their specific working methods and control methods are all mature existing technologies and have been disclosed, so they will not be described in detail in this article.
[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
