Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, specifically to an automatic post-treatment device for hot-dip galvanizing of bolts. Background Technology

[0002] Hot-dip galvanizing is one of the commonly used anti-corrosion treatment methods for fasteners, especially suitable for fasteners such as bolts that need to withstand large tensile and shear forces. However, traditional hot-dip galvanizing post-treatment equipment for bolts still has certain defects. Existing equipment is highly dependent on manual operation, resulting in low production efficiency and difficulty in controlling the uniformity and thickness of the galvanized layer. At the same time, the traditional post-treatment process has a low degree of automation and mostly relies on manual labor, resulting in low output capacity. Furthermore, traditional equipment consumes a lot of energy during the post-treatment process. Therefore, an automatic hot-dip galvanizing post-treatment equipment for bolts is proposed. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic post-treatment device for hot-dip galvanizing of bolts to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic post-processing device for hot-dip galvanizing of bolts, comprising a robotic arm for gripping, a centrifuge for removing excess zinc liquid, and a gantry robot. The robotic arm and the centrifuge are both located on one side of the gantry robot, and the robotic arm is located behind the centrifuge. A cooling tank, a passivation tank, and a feeding conveyor are respectively installed below the gantry robot, and the passivation tank is located on the side adjacent to the cooling tank and the feeding conveyor.

[0005] It also includes a galvanized basket for holding the workpiece, the outer diameter of which is smaller than the inner diameter of the centrifuge.

[0006] As a further preferred embodiment of this technical solution: the galvanized basket that has completed galvanizing is quickly grabbed by a robotic arm and transferred to the centrifuge station, and accurately placed into the centrifuge. The centrifuge then removes excess molten zinc from the surface of the workpiece, ensuring that the galvanized layer on the workpiece is uniform and of appropriate thickness.

[0007] As a further preferred embodiment of this technical solution: the gantry manipulator includes a frame, a translation mechanism is installed on the top of the frame, a lifting mechanism is installed on one side of the translation mechanism, and a gripper is installed at the bottom of the lifting mechanism.

[0008] As a further preferred embodiment of this technical solution: the frame provides stable support for the overall operation of the gantry robot, the translation mechanism is used for horizontal movement on the frame, and efficient collaborative operation is achieved through the frame, while the translation mechanism drives the lifting mechanism and the gripper installed on it to move horizontally.

[0009] As a further preferred embodiment of this technical solution: the lifting mechanism is used for vertical movement, and the gripper is used for picking up or putting down the galvanized basket. The lifting mechanism drives the gripper to move vertically, and the gripper drives the galvanized basket.

[0010] As a further preferred embodiment of this technical solution: both the cooling pool and the passivation pool are equipped with multiple workstations, and each of the multiple workstations is equipped with a lifting frame. The multiple workstations effectively prevent cross-contamination of the processing liquids between different processes, while the lifting frame drives the galvanizing basket to descend or rise.

[0011] As a further preferred embodiment of this technical solution: the cooling pool is used to terminate the coating reaction, and the passivation pool is used to enhance the surface quality of the coating and the wear resistance of the material. The surface quality of the workpiece is enhanced by the cooling pool, thereby effectively reducing the risk of high-temperature deformation, and the service life of the workpiece is extended by the passivation pool.

[0012] As a further preferred embodiment of this technical solution: the size of the conveyor chain of the unloading conveyor is adapted to the size of the galvanized basket, and the unloading conveyor transports the workpiece after the post-processing to the discharge position.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses automated equipment such as robotic arms, gantry robots and unloading conveyors to achieve seamless integration of bolt hot-dip galvanizing post-processing equipment, thereby effectively improving the overall automation level of the device. This greatly reduces manual operation and avoids the situation of low production efficiency and low capacity caused by manual operation.

[0015] 2. In this utility model, the centrifuge is set up to remove excess zinc liquid from the surface of the workpiece, thereby ensuring the uniformity and appropriate thickness of the zinc coating on the workpiece and ensuring the quality of the zinc coating on the bolt. This effectively solves the problem of difficulty in controlling the uniformity and thickness of the zinc coating after the traditional equipment is in operation.

[0016] 3. This utility model can effectively improve production efficiency by replacing manual operation with automated equipment, which greatly shortens the processing time, thereby increasing the processing capacity of a single batch of workpieces and greatly improving the production capacity, which can reach more than three times that of traditional production lines.

[0017] 4. In this utility model, the lifting frame carries the galvanized basket for cooling and passivation, and then raises the drain liquid, which can effectively prevent cross-contamination of the processing liquid between each process. Furthermore, the corresponding workstations and lifting frame can prevent the galvanized basket from carrying excess passivation liquid to the next process, thereby effectively achieving the requirements of energy conservation and environmental protection.

[0026] It also includes a galvanized basket 3 for holding workpieces, the outer diameter of which is smaller than the inner diameter of the centrifuge 2.

[0027] In this embodiment, specifically: the robotic arm 1 quickly grabs the galvanized basket 3 that has completed galvanizing and transfers it to the centrifuge station, accurately placing it into the centrifuge 2. The centrifuge 2 then removes excess molten zinc from the surface of the workpiece, ensuring that the galvanized layer on the workpiece is uniform and of appropriate thickness.

[0028] Centrifuge 2 can process a maximum of 50kg of workpieces at a time, and its centrifugal speed is adjustable by frequency conversion.

[0029] In this embodiment, specifically, the galvanized basket 3 is configured with a suitable specification based on the different diameters and lengths of workpieces (bolts or screws) used in actual use.

[0030] In this embodiment, specifically: the gantry robot 4 includes a frame 41, a translation mechanism 42 is installed on the top of the frame 41, a lifting mechanism 43 is installed on one side of the translation mechanism 42, and a gripper 44 is installed at the bottom of the lifting mechanism 43.

[0031] In this embodiment, specifically: the frame 41 provides stable support for the overall operation of the gantry robot 4, and the translation mechanism 42 is used to perform horizontal movement on the frame 41. Efficient collaborative operation is achieved through the frame 41, and the translation mechanism 42 drives the lifting mechanism 43 and the gripper 44 installed on it to perform horizontal movement.

[0032] In this embodiment, specifically: the lifting mechanism 43 is used for vertical movement, and the gripper 44 is used for picking up or putting down the galvanized basket 3. The lifting mechanism 43 can drive the gripper 44 to move vertically, and the gripper 44 is used to drive the galvanized basket 3.

[0033] Example 2

[0034] An automatic post-treatment equipment for hot-dip galvanizing of bolts is provided, with multiple workstations in both the cooling tank 5 and the passivation tank 6, and each workstation is equipped with a lifting frame 7. The multiple workstations can effectively prevent cross-contamination of the treatment liquids between different processes, and the lifting frame 7 is used to drive the galvanizing basket 3 to descend or rise.

[0035] In this embodiment, specifically: the cooling pool 5 is used to terminate the coating reaction, and the passivation pool 6 is used to enhance the surface quality of the coating and the wear resistance of the material. The cooling pool 5 is used to enhance the surface quality of the workpiece, thereby effectively reducing the risk of high-temperature deformation, while the passivation pool 6 is used to extend the service life of the workpiece.

[0036] In this embodiment, specifically: the size of the conveyor chain of the unloading conveyor 8 is adapted to the size of the galvanized basket 3, and the unloading conveyor 8 is used to transport the workpiece after the post-processing to the discharge position.

[0037] Working principle: During operation, the system first selects the appropriate galvanizing basket 3 according to the different diameters and lengths of the workpieces used, and loads the workpieces into the galvanizing basket 3. The galvanizing operation is completed in the zinc pot. Then, the robotic arm 1 quickly grabs the galvanized basket 3 and transfers it to the centrifuge station, and accurately places it into the centrifuge 2. The centrifuge 2 drives the galvanizing basket 3 to rotate at high speed, which removes excess zinc liquid from the surface of the workpiece, ensuring that the galvanized layer of the workpiece is uniform and of appropriate thickness.

[0038] The lifting mechanism 43 and gripper 44 in the gantry robot 4 quickly grab and remove the galvanized basket 3 that has completed the centrifugation process. At the same time, the translation mechanism 42 drives the galvanized basket 3 to move horizontally on the frame 41, and the cooling and passivation processes are completed in the cooling pool 5 and the passivation pool 6 in sequence.

[0039] To achieve high-speed flow of post-processing, the cooling tank 5 is equipped with multiple workstations, each with a lifting frame 7. The gantry robot 4 places the galvanizing basket 3 on the lifting frame 7, and the lifting frame 7 lowers the galvanizing basket 3 into the cooling tank 5 to complete the cooling of the workpiece. Then the drain liquid is raised, which can effectively prevent cross-contamination of the processing liquid between processes. At the same time, the passivation tank 6 is also equipped with corresponding workstations and lifting frames 7 to prevent the galvanizing basket 3 from carrying excess passivation liquid to the next process, thereby effectively achieving the requirements of energy saving and environmental protection.

[0040] Finally, the gantry robot 4 picks up the galvanized basket 3 that has completed cooling and passivation and places it onto the unloading conveyor 8. The size of the conveyor chain of the unloading conveyor 8 is adapted to the size of the galvanized basket 3. The unloading conveyor 8 transports the workpiece after the post-processing to the discharge position, completing all the processes.
