Description

Technical Field

[0001] This invention relates to the field of anchor bolt processing technology, specifically to an anti-corrosion spraying device for anchor bolt processing. Background Technology

[0002] Anchor bolt processing is a complete manufacturing technology system encompassing the entire process from raw materials to finished products. It covers four key stages: raw material selection, forming and processing, precision treatment, and corrosion protection. High-strength carbon steel or stainless steel is primarily used as raw material, with wire drawing processes optimizing the material's mechanical properties. The forming stage mainly utilizes cold heading, employing a multi-station cold heading machine to achieve integrated forming of the anchor bolt head and shank. Subsequent thread rolling ensures complete thread profile and precise fit. Precision treatment involves using CNC lathes or grinding machines to finely machine the shank end face and head flatness. In some high-precision applications, heat treatment is also required to improve the overall hardness and toughness of the anchor bolt. Corrosion protection is the core technology ensuring the quality of anchor bolt processing; common processes include hot-dip galvanizing, electro-galvanizing, powder coating, and special anti-corrosion paint spraying.

[0003] Existing technical solutions for anti-corrosion spraying of anchor bolts suffer from low automation. They require manual intervention in steps such as workpiece transfer, spraying angle adjustment, and touch-up spraying. This not only relies on skilled workers, but human error can also easily lead to inaccurate positioning and uneven spraying thickness. Furthermore, direct contact with the anti-corrosion coating poses health risks to personnel. In terms of spraying precision, it is difficult to effectively cover the gaps in the anchor bolt threads, resulting in a high rate of missed spraying in critical areas. Areas that are clamped or covered require subsequent manual touch-up spraying, which can easily lead to coating overlay or localized oxidation, causing anchor bolt corrosion.

[0013] Preferably, the workpiece fixing component further includes: a limiting slide rail assembly, a clamping seat, a rotating disk, connecting rods, and a sixth motor; the limiting slide rail assembly consists of two sets, with two assemblies in each set, and the two sets of limiting slide rail assemblies are respectively installed on the front and rear sides of the top center of the mounting base; the clamping seat consists of two sets, and the two clamping seats are respectively installed on the top of the limiting ends of the front and rear sets of limiting slide rail assemblies; the rotating disk is rotatably connected to the top of the mounting base via bearings and is located inside the front and rear sets of limiting slide rail assemblies; the connecting rod consists of two sets, with one end of each connecting rod rotatably installed on the left and right sides of the bottom end of the rotating disk via a rotating shaft, and the other end of each connecting rod rotatably connected to the bottom ends of the front and rear clamping seats via a rotating shaft; the sixth motor is installed above the rotating disk, the rotating end of the rotating disk is fixedly connected to the axis of the rotating disk, and the sixth motor is electrically connected to the controller.

[0014] Preferably, the sixth motor drives the rotating disk to rotate clockwise. When the rotating disk rotates, one end of the connecting rod on the left and right sides of its bottom end moves inward with the rotating disk, and the other end pulls the front and rear clamping seats through the rotating shaft. Since the clamping seats clamp the bottom end of the outer wall of the anchor bolt under the limit of the limiting slide rail assembly, the workpiece is fixed.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The workpiece on its surface is conveyed from back to front by an electric conveyor belt to the gripping position below the handling robot arm. After the handling robot arm grips the workpiece on the surface of the electric conveyor belt, it is transferred by the transfer component and placed inside the workpiece fixing component. The sixth motor drives the rotating disk to rotate, causing the rotating disk to drive one end of the front and rear connecting rods to move inward, which in turn drives the corresponding clamping seat on the front and rear connecting rods to move inward under the limiting action of the limiting slide rail assembly. The front and rear clamping seats clamp the bottom end of the outer wall of the workpiece for fixation. The first motor drives the gear in the ring gear set to rotate, causing the gear in the ring gear set to move circumferentially along the outer side of the ring half gear, and driving the roller moving platform to move in an arc along the top of the slide rail to the designated position outside the workpiece fixing component. Two electric telescopic rods extend to drive the moving robotic arm above the mounting platform to approach the workpiece. The moving robotic arm drives the storage tank to move in three axes, so that the double-end rotating module drives the nozzle to rotate to a specified angle, aligning the nozzle with the workpiece. The supply pump pumps the anti-corrosion paint stored in the storage tank into the nozzle. The nozzle performs a large-scale anti-corrosion paint spraying operation on the outside of the workpiece. The double-end rotating module drives the connecting pipe head to rotate to a specified position. The micro motor drives the gear in the second ring gear set to rotate, so that the ring gear in the second ring gear set drives the nozzle to rotate along the inclined surface of the connecting pipe head, thereby rotating the nozzle to a specified tilt angle position. The supply pump pumps the anti-corrosion paint stored in the storage tank into the connecting pipe head, and the nozzle sprays it into the inside of the workpiece's threaded gaps at a specified angle.

[0017] 2. The first rotating rod at the corresponding position is driven to rotate inward by the second motor on both the front and rear sides, the rotating frame at the corresponding position is driven to rotate inward by the third motor on both the front and rear sides, and the second rotating rod at the corresponding position is driven to rotate inward by the fourth motor on both the front and rear sides. This causes the rollers on both the front and rear sides to fit against the outside of the workpiece. The sixth motor drives the rotating disk to rotate in the opposite direction, so that the clamping seats on both the front and rear sides move outward with the cooperation of the connecting rods on both sides to release the clamping and fixing of the workpiece, so that the spraying component can perform the painting operation on the original clamping position of the workpiece.

[0018] In summary, this invention enables fully automated operation of the anchor bolt anti-corrosion painting process, completing the workpiece conveying, positioning, spraying, and output without manual intervention, thereby improving production efficiency. Furthermore, addressing traditional spraying issues such as anchor bolt thread gaps and clamping obstructions, the invention achieves comprehensive coverage of critical areas through an adjustable-angle fine spraying design and dynamic clamping switching, enhancing the anchor bolt's corrosion resistance and effectively extending its service life.

On the side, the rotating ends of the two fifth motors 79 are respectively connected to the shafts of the front and rear rollers 78. The fifth motors 79 and the controller 4 are electrically connected. The fifth motors 79 are DC servo motors and drive the rollers 78 to rotate. There are two sets of limit slide rail assemblies 710, and each set of limit slide rail assemblies 710 has two components. The two sets of limit slide rail assemblies 710 are respectively installed on the front and rear sides of the top center of the mounting base 71. The limit slide rail assembly 710 adopts a miniature linear guide rail, and each one contains a guide rail and a slider. There are two clamping seats 711. The two clamping seats 711 are respectively installed on the top of the limiting ends of the front and rear sets of limit slide rail assemblies 710. The clamping seats 711 are made of MC nylon material and have a "C" shaped structure.The rotating disk 712 is rotatably connected to the top of the mounting base 71 via bearings and is located inside the front and rear sets of limit slide rail assemblies 710. There are two connecting rods 713, one end of which is rotatably mounted on the left and right sides of the bottom of the rotating disk 712 via a rotating shaft. The other ends of the two connecting rods 713 are rotatably connected to the bottom of the front and rear clamping seats 711 via rotating shafts. A sixth motor 714 is mounted above the rotating disk 712. The rotating end of the rotating disk 712 is fixedly connected to its shaft. The sixth motor 714 is electrically connected to the controller 4. The sixth motor 714 is a stepper motor with a brake. The sixth motor 714 drives the rotating disk 712 to rotate, and the controller 4 controls the rotation angle via pulse signals to achieve precise opening and closing of the clamping seats 711.

[0033] The working principle is as follows:

[0034] Step 1: The upstream production line conveyor smoothly transfers the anchor bolt workpieces to be processed onto the surface of the electric conveyor belt 1. The controller 4, according to a preset program, synchronously starts the electric conveyor belt 1, the handling robotic arm 2, the top housing 32, the three-axis moving platform 52, the first electric telescopic rod 56, and the clamping module 55. The electric conveyor belt 1 transports the anchor bolts from back to front at a set speed until the workpiece is delivered to the designated gripping position below the handling robotic arm 2. Simultaneously, the handling robotic arm 2 grips the anchor bolts on the electric conveyor belt 1 using its end gripper. At the same time, the inner sealing door of the top housing 32 automatically opens, and the three-axis moving platform 52 of the transfer component 5 drives the L-shaped frame 53, moving the clamping module 55 below to the workpiece transfer position. The first electric telescopic rod 56 shortens, and the workpiece is transferred via a rotating mechanism. The shaft drives the rotating seat 54 to rotate counterclockwise inside the L-shaped frame 53, thereby causing the clamping module 55 at the bottom of the rotating seat 54 to rotate 90° counterclockwise from the downward position to the right position to wait for the workpiece. The transport robot arm 2 passes through the sealed door of the top shell 32 and accurately places the workpiece into the inside of the clamping module 55 of the transfer component 5. The clamping module 55 clamps the outer wall of the anchor bolt. The transport robot arm 2 releases the clamp, moves out of the top shell 32 and returns to the initial position to reset. The sealed door of the top shell 32 automatically closes, forming a closed spraying space. The three-axis moving platform 52 of the transfer component 5 starts again, driving the clamping module 55 to move directly above the workpiece fixing component 7. The anchor bolt is slowly lowered and placed stably on the designated fixing position of the workpiece fixing component 7, completing the workpiece entry process.

[0035] Step 2: Controller 4 starts the paint supply equipment 33. The paint supply equipment 33, through its built-in pump, pressurizes and pumps the anti-corrosion paint it stores into the storage tank 69 of the spraying component 6. The storage tank 69 temporarily stores the paint to provide a continuous supply for subsequent spraying. Controller 4 starts the sixth motor 714, the first motor 64, the second electric telescopic rod 67, the moving robotic arm 68, the double-end rotating module 612, the supply pump 610, the spray nozzle 613, and the micro motor 616. The sixth motor 714 drives the rotating disk 712 to rotate clockwise. When the rotating disk 712 rotates, one end of the connecting rod 713 on the left and right sides of its bottom rotates with it. The disc moves inward, while the other end pulls the two clamping seats 711 at the front and rear via the rotating shaft. Because the clamping seats 711 are clamped to the bottom end of the anchor bolt's outer wall under the limiting slide rail assembly 710, the workpiece is fixed. The first motor 64 drives the gears in the ring gear set 62 to rotate. Since the arc-shaped rack of the ring gear set 62 is fixed along the inner side of the top of the slide rail 61, the gears move circumferentially along the arc-shaped rack, thereby driving the roller moving platform 63 to move along the arc-shaped trajectory of the slide rail 61, precisely delivering the spraying component to the designated spraying position outside the workpiece fixing component 7. The second electric telescopic rod 67 extends. The installation platform 66 is pushed inward towards the workpiece under the limiting action of the guide rail limiting component 65, so that the moving robotic arm 68 on the installation platform 66 is closer to the anchor bolt. The moving robotic arm 68 drives the storage tank 69 to move. The mounting bracket 611 below the storage tank 69 drives the double-end rotating module 612 to move slowly along the outside of the anchor bolt. One rotating end of the double-end rotating module 612 drives the nozzle 613 to rotate to a specified angle aligned with the outer surface of the anchor bolt. The supply pump 610 is started, pressurizing and pumping the anti-corrosion paint in the storage tank 69 into the nozzle 613. The nozzle 613 begins to spray the large areas of the outer surface of the anchor bolt, such as the rod and head. The anti-corrosion paint is sprayed over a large area to complete the spraying operation. While the large area is being sprayed, the other rotating end of the double-ended rotating module 612 drives the connecting pipe head 614 to rotate to align with the thread gap of the anchor bolt. The micro motor 616 starts and drives the gear in the second ring gear set 617 to rotate, which in turn drives the ring gear fixed to the outer wall of the nozzle 615 to rotate. This causes the nozzle 615 to rotate along the inclined surface of the connecting pipe head 614 to a specified position that fits the angle of the thread gap. The supply pump 610 pumps the anti-corrosion paint into the connecting pipe head 614, and then sprays it precisely into the thread gap of the anchor bolt through the nozzle 615 to avoid missing the gap.

[0036] Step 3: Since the workpiece is fixed by clamping its bottom end through the clamping seat 711, the area where the bottom end of the anchor bolt contacts the clamping seat will be blocked, preventing spraying. The controller 4 activates the second motor 72, third motor 74, fourth motor 76, and fifth motor 79 of the workpiece fixing component 7. The second motor 72 on both the front and rear sides drives the first rotating rod 73 at the corresponding position to rotate inward, the third motor 74 on both the front and rear sides drives the rotating frame 75 at the corresponding position to rotate inward, and the fourth motor 76 on both the front and rear sides drives the second rotating rod 77 at the corresponding position to rotate inward. The coordinated action of the second motor 72, the third motor 74, and the fourth motor 76 causes the rollers 78 on both the front and rear sides to move closer to the anchor bolt and fit tightly against the outer wall of the anchor bolt. The sixth motor 714 starts and drives the rotating disk 712 to rotate in the opposite direction. The rotating disk 712 drives one end of the connecting rod 713 on both the front and rear sides to move outward, thereby pulling the two clamping seats 711 on the front and rear sides to move outward along the limiting slide rail assembly 710, releasing the original clamping fixation and releasing the original clamping position. The moving robotic arm 68 drives the spray head 613 or nozzle 615 to move to the area of ​​the original clamping position of the anchor bolt and sprays the area.

[0037] Step 4: After the anchor bolt is fully coated, the sealed door of the top shell 32 automatically opens again. The handling robot arm 2 starts and extends into the top shell 32, moving to the workpiece transfer position to receive the workpiece. The three-axis moving platform 52 of the transfer component 5 drives the clamping module 55 to move above the coated anchor bolt. The clamping module 55 clamps the outer wall of the anchor bolt. The relevant structure of the workpiece fixing component 7 releases the anchor bolt. The three-axis moving platform 52 moves the clamping module 55 and the workpiece to the transfer position. The end clamp of the handling robot arm 2 clamps the anchor bolt on the clamping module 55, and at the same time the clamping module 55 is released, completing the transfer of the workpiece. The handling robot arm 2, carrying the coated anchor bolt, moves out of the top shell 32 and places the anchor bolt on the surface of the electric conveyor belt 1. The electric conveyor belt 1 starts and transports the coated anchor bolt from back to front until it is sent to the downstream process, thus completing the entire process of anchor bolt anti-corrosion spraying.
