Description

Technical Field

[0001] This application relates to the technical field of galvanizing equipment, and in particular to a dual robotic arm processing system for galvanized guardrail panels. Background Technology

[0002] A dual-robotic arm processing system for galvanized guardrail panels is an automated system for galvanizing guardrail panels. It is widely used in the production and manufacturing of guardrail panels for transportation infrastructure such as highways, railways, and bridges. It can effectively improve the corrosion resistance of guardrail panels and extend their service life. In the existing galvanizing process for guardrail panels, the stacked guardrail panels are usually manually moved one by one to the feeding conveyor belt. The conveyor belt transports the guardrail panels to a designated position above the galvanizing tank. Then, a single robotic arm moves to the guardrail panel, clamps it, and immerses it in the galvanizing tank. After galvanizing is completed, the single robotic arm must first remove the guardrail panel from the galvanizing tank and move it above the transfer conveyor belt. Then, it releases the clamp and places the panel on the conveyor belt to be transported away from the galvanizing area. When using existing galvanizing processes for guardrail panels, a single robotic arm needs to complete the entire process of picking up the panels from the feed conveyor belt, immersing them in the galvanizing bath, removing them, and placing them on the transfer conveyor belt. There are time intervals between these processes, which affects the efficiency of galvanizing the guardrail panels. Summary of the Invention

The first chain conveyor is installed on the ground, and guardrail panels are placed on it, with corrugated pads placed on the guardrail panels. The mounting frame is vertically arranged, and a controller is installed on one side of the mounting frame, electrically connected to the first chain conveyor. The galvanizing box is vertically arranged on one side of the mounting frame, with an inlet on the side near the mounting frame and an outlet on the other side. A galvanizing tank is fixedly installed inside the galvanizing box; the feeding assembly is located on the mounting frame and is used to drive the guardrail panel body to move into the galvanizing box through the feed port; the collecting assembly is located on one side of the mounting frame and is used to collect the corrugated pads on the guardrail panel body; the clamping assembly is located inside the galvanizing box and is used to clamp the guardrail panel body into the galvanizing tank; the transfer assembly is located inside the galvanizing box and is used to transfer the galvanized guardrail panel body to the outside of the galvanizing box through the discharge port; the air drying assembly is located inside the galvanizing box and is used to dry the galvanized guardrail panel body.

[0007] By adopting the above technical solution, during use, the operator drives the movable end of the feeding hydraulic cylinder to extend via the controller. The movable end of the feeding hydraulic cylinder drives the electromagnetic chuck to move synchronously.

The controller controls the electromagnetic chuck to attract the guardrail body, the controller controls the movable end of the feeding hydraulic cylinder to retract, and the controller controls the linear motor to work.

[0009] By adopting the above technical solution, when the second chain conveyor transports the guardrail body, the operator controls the flipping motor to work through the controller. The flipping motor drives the flipping frame to rotate, and the flipping frame drives the guardrail body on the second chain conveyor to flip 180 degrees, making the corrugated pads on the guardrail body easy to fall off. The collection unit collects the fallen corrugated pads, making the corrugated pads easy to reuse.

[0010] Optionally, the collecting section includes a guide plate and a collecting vehicle; the guide plate is inclined and fixedly connected to the top of the connecting frame; the collecting vehicle is vertically arranged and located on the side of the guide plate away from the second chain conveyor.

[0011] By adopting the above technical solution, when the tilting frame drives the guardrail body on the second chain conveyor to rotate 180 degrees, the corrugated pad on the guardrail body falls onto the guide plate, and the corrugated pad slides down the guide plate into the collection vehicle, completing the collection of the corrugated pad, making the corrugated pad easy to reuse.

[0015] By adopting the above technical solution, during use, the operator uses the controller to drive the movable ends of the first and second clamping hydraulic cylinders to extend. The first clamping hydraulic cylinder drives the first clamping rod and the first limiting rod to limit the guardrail body to be galvanized, and the second clamping hydraulic cylinder drives the second clamping rod and the second limiting rod to limit the guardrail body after galvanization.

Below the guardrail body; the operator drives the movable ends of the first and second drive cylinders to retract via the controller, causing the guardrail body to be galvanized to move above the second limit frame. After galvanizing, the guardrail body moves to the transfer assembly. The controller controls the second clamping hydraulic cylinder to place the galvanized guardrail body at the transfer assembly, and simultaneously controls the first clamping hydraulic cylinder to place the guardrail body to be galvanized onto the second limit frame.

When the galvanized guardrail body falls onto the transfer roller, the controller controls the movable end of the second drive cylinder to reset, and the movable end of the second drive cylinder squeezes the airbag. The air in the airbag flows into the drying chamber through the connecting pipe and the first one-way valve. At the same time, the transfer roller transfers the guardrail body to the drying chamber.

A first wave-shaped clearance hole 811 is provided on one side of the drying chamber 81, and a second wave-shaped clearance hole 812 is provided on the side of the drying chamber 81 away from the first wave-shaped clearance hole 811. The placement plate 82 is vertically installed at the top of the galvanized box 3 and is rectangular in shape. The placement plate 82 is fixedly connected to the galvanized box 3. The air bladder 83 is horizontally installed at one end of the placement plate 82 near the second drive cylinder 621 and is fixedly connected to the placement plate 82. The air bladder 83 abuts against two sets of second clamping hydraulic cylinders 622. The air bladder 83 is hollow inside and filled with air. The connecting pipe 84 is a circular tube, with both ends connected to the inside of the airbag 83 and the drying chamber 81, respectively. A first one-way valve 841 is installed on the connecting pipe 84. The reset pipe 85 is a circular tube located at the top of the airbag 83. One end of the reset pipe 85 is connected to the inside of the airbag 83, and the other end is connected to the outside. A second one-way valve 851 is installed on the reset pipe 85.

[0045] In use, the galvanized guardrail body 11 falls onto the transfer roller 72. The controller 21 controls the transfer motor 73 to work, and the transfer motor 73 drives the transfer roller 72 to rotate. The transfer roller 72 drives the galvanized guardrail body 11 to move towards the discharge port 32. At the same time, the controller 21 controls the movable end of the second drive cylinder 621 to reset. The movable end of the second drive cylinder 621 squeezes the air bag 83. The air in the air bag 83 flows into the drying chamber 81 through the connecting pipe 84 and the first one-way valve 841. The transfer roller 72 transfers the guardrail body 11 to the drying chamber 81. The guardrail body 11 passes through the first wave relief hole 811 and the second wave relief hole 812 into the drying chamber 81. Air enters the drying chamber 81 and blows air onto the surface of the guardrail body 11 to dry it.

[0046] The implementation principle of the dual robotic arm processing system for galvanized guardrail panels in this application embodiment is as follows: When the guardrail body 11 is galvanized, the operator drives the movable end of the feeding hydraulic cylinder 42 to extend through the controller 21. The controller 21 controls the electromagnetic chuck 43 to attract the guardrail body 11. The controller 21 controls the movable end of the feeding hydraulic cylinder 42 to retract. The controller 21 controls the linear motor 41 to work. When the electromagnetic chuck 43 moves above the second chain conveyor 44, the controller 21 controls the electromagnetic chuck 43 to stop working, and the guardrail body 11 attracted by the electromagnetic chuck 43 falls onto the second chain conveyor 44.

[0047] When the guardrail body 11 on the second chain conveyor 44 is transferred, the controller 21 controls the flipping motor 521 to work. The flipping motor 521 drives the flipping frame 522 to rotate. The flipping frame 522 drives the guardrail body 11 on the second chain conveyor 44 to flip 180 degrees. The corrugated pad 12 on the guardrail body 11 falls onto the guide plate 531. The corrugated pad 12 slides along the guide plate 531 into the collection vehicle 532, completing the collection of the corrugated pad 12.

[0048] Controller 21 controls the second chain conveyor 44 to continue operating, and the guardrail body 11 moves above the first limiting frame 33. The baffle 34 guides the sliding direction of the guardrail body 11, and the guardrail body 11 slides onto the first limiting frame 33. Controller 21 drives the first robotic arm 61 to clamp the guardrail body 11 to be galvanized and move it onto the second limiting frame 351. The second robotic arm 62 clamps the galvanized guardrail body 11 and moves it onto the transfer roller 72. Controller 21 controls the transfer motor 73 to operate, and the transfer motor 73 drives the galvanized guardrail body 11 to be transferred outside the galvanizing box 3 via the transfer roller 72.

[0049] At the same time, the controller 21 controls the movable end of the second drive cylinder 621 to reset. The movable end of the second drive cylinder 621 squeezes the airbag 83. The air in the airbag 83 flows into the drying chamber 81 through the connecting pipe 84 and the first one-way valve 841. The guardrail body 11 passes through the drying chamber 81 through the first waveform clearance hole 811 and the second waveform clearance hole 812. The air enters the drying chamber 81 and blows air to dry the surface of the guardrail body 11.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
