Description

Technical Field

[0001] This utility model relates to the field of guardrail processing technology, specifically to a dual-robotic arm automatic galvanizing device. Background Technology

[0002] Guardrails are semi-rigid safety facilities used for protection on roads. They mainly absorb collision energy through the deformation of corrugated beams, posts, and soil base, guiding out-of-control vehicles to change direction and reduce accident losses.

[0003] Currently, some of our single-robotic-arm galvanizing production lines have many problems that restrict economic efficiency.

[0004] First, the single robotic arm production mode results in insufficient production capacity, making it difficult to meet the production demand for powder-coated guardrail panels, which in turn limits the expansion of the overall production scale. The single robotic arm production line cannot adapt to the high-efficiency and precision requirements of modern production.

[0005] Secondly, the galvanizing production line requires a large workforce. Currently, our galvanizing production line, as well as most galvanizing production lines on the market, are difficult to fully automate and generally require manual intervention. For example, during material loading, manual assistance is needed to install the guardrail panels onto the hoisting equipment, which then completes the automated galvanizing process. After galvanizing, manual assistance is still needed to unload the materials, resulting in low production efficiency. Employees need to frequently operate the equipment, leading to high labor intensity. Furthermore, human factors have a significant impact on product quality during the production process, which is not conducive to the stable improvement of product quality. Utility Model Content

[0006] This invention provides a dual-robotic-arm automatic galvanizing device to solve the technical problems of difficulty in achieving fully automated operation and low galvanizing efficiency in existing galvanizing production lines.

[0007] To solve the above problems, the dual-arm automatic galvanizing device provided by this utility model adopts the following technical solution: it includes a receiving and positioning mechanism, which is set on one side of the zinc pot. The receiving and positioning mechanism is used to receive the guardrail plate discharged from the feeding mechanism and position the guardrail plate.

[0008] Material racks are installed inside the zinc pot to fix the guardrail panels. The material racks have several material slots for accommodating the guardrail panels, and there are at least two material racks.

[0009] A driving device is provided above the zinc pot. The driving device includes a translation mechanism for driving the guardrail to move horizontally and a lifting mechanism for driving the guardrail to rise and fall.

[0010] The gripping mechanism is used to grip the guardrail panel and is connected to the lifting mechanism; both the drive unit and the gripping mechanism are equipped with two sets, which work alternately to improve work efficiency.

[0011] The discharge mechanism is located on the side of the zinc pot away from the receiving and positioning mechanism. The discharge mechanism is used to transport the galvanized guardrail panels.

[0012] As a further improvement, the receiving and positioning mechanism has an integrally formed arc-shaped receiving structure on the side near the feeding mechanism, so that the guardrail plate falls into the receiving and positioning mechanism along the arc-shaped receiving structure and remains vertical, so that the gripping mechanism can grasp it.

[0013] As a further improvement, the gripping mechanism includes a rotatable limiting rod and a cooperating rod that cooperates with the cooperating rod to fix the guardrail plate. The bottom of the limiting rod is provided with a limiting structure for limiting the guardrail plate.

[0014] The limit bar has a working position and a clearance position during its rotation stroke. When the limit bar is in the working position, the limiting structure at the bottom of the limit bar is close to the cooperating bar to achieve the gripping of the guardrail. When the limit bar is in the clearance position, the limiting structure at the bottom of the limit bar is far away from the cooperating bar to provide clearance for gripping or release the gripping of the guardrail.

[0015] As a further improvement, the limiting rod is connected to the lifting mechanism via a rotating structure.

[0016] As a further improvement, the discharge mechanism includes several discharge rollers, which are connected to the bearing housing via bearings, and are also connected to an external motor drive.

[0017] As a further improvement, the discharge roller is a tapered roller to position the guardrail during conveying.

[0018] As a further improvement, a buffer mechanism for receiving guardrail plates is provided between adjacent discharge rollers. The buffer structure includes a wedge frame and a drive cylinder for driving the wedge frame to rotate.

[0019] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0020] 1. This utility model solves the problem of receiving and positioning guardrail panels at a very low cost by setting up a receiving and positioning mechanism, which facilitates the subsequent gripping mechanism to grip them.

[0021] 2. This utility model significantly improves work efficiency by setting up two sets of gripping mechanisms to work alternately. One set of gripping mechanisms is responsible for gripping the guardrail panels, while the other set of gripping mechanisms is responsible for gripping the galvanized guardrail panels to the discharge mechanism. Compared with existing automatic galvanizing equipment, this greatly improves work efficiency.

[0022] The gripping mechanism uses a rotatable limiting rod and a cooperating rod to grip the guardrail panel. During gripping, the limiting rod is first rotated to avoid the guardrail panel, causing the gripping mechanism to descend to a set position. Then, the limiting rod rotates again, positioning the limiting structure below the guardrail panel, thus achieving gripping. This gripping mechanism is easy to operate, does not require high positioning accuracy to grip materials, has relatively low cost, and is highly practical.

[0023] Compared to existing galvanizing production lines, this invention significantly increases production output, with a maximum speed of 5 pieces / minute and a single cycle time of approximately 12 seconds. The actual output per shift can reach ≥2500 pieces. After the technical upgrade to a dedicated powder coating line, the production capacity increases by more than 50%. Based on 4mm plates, the production capacity is approximately 500 tons / day, and based on 3mm plates, the production capacity is approximately 450 tons / day. This effectively solves the problem of insufficient production capacity and meets the market's demand for product quantity.

[0024] 3. This utility model incorporates a buffer mechanism to ensure the guardrail panels can be laid flat and stably. After being lowered, the guardrail panels first rest against the wedge-shaped frame to prevent direct impact on the discharge roller. Then, the wedge-shaped frame rotates, causing the guardrail panels to flip onto the discharge roller at a uniform speed. Because the discharge roller has a conical structure, the guardrail panels move towards one side during transport, achieving positioning and facilitating subsequent processes.

[0025] 4. The highly automated production process of this utility model reduces manual intervention, minimizes the impact of human factors on product quality, and improves product quality stability. During equipment operation, the stable mechanical structure results in a failure rate of less than 2‰ (excluding problems not related to the equipment's operation, such as human error or violations), reducing equipment maintenance time and costs and ensuring continuous production.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] In existing technologies, galvanizing production lines mainly suffer from low galvanizing efficiency and difficulty in achieving full automation at a relatively low cost.

[0035] Regarding the above-mentioned problems, the inventive concept of this utility model is as follows:

[0036] The first issue is the problem of loading and unloading materials. This utility model extends the feeding mechanism to one side of the zinc pot and sets up a material receiving and positioning mechanism, so that the guardrail can be directly transported to the side of the zinc pot and positioned.

[0037] The gripping mechanism uses rotatable limit rods and cooperating rods to grasp the guardrail panels, resulting in a low failure rate and minimizing damage to the main components. A material rack is installed inside the zinc pot, enabling the two gripping mechanisms to operate alternately.

[0038] Finally, the buffer mechanism ensured the smooth discharge of the guardrail panels.

[0039] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0040] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0041] Embodiment 1 of the buffer mechanism of the dual-robotic arm automatic galvanizing device provided by this utility model:

[0042] like Figures 1-4As shown, the buffer mechanism of the dual-arm automatic galvanizing device includes a feeding mechanism 1, a receiving and positioning mechanism 2, a drive device positioned above the zinc pot 7, a gripping mechanism 4 installed at the bottom of the drive device, a material rack 8 located inside the zinc pot 7, a discharge mechanism 6 located on the other side of the zinc pot 7, and a buffer mechanism 5. The length direction of the zinc pot 7 is defined as the front-to-back direction, and the width direction of the zinc pot 7 is defined as the left-to-right direction.

[0043] like Figure 1 As shown, the receiving and positioning mechanism 2 is located on the left side (opposite) of the zinc pot 7. The receiving and positioning mechanism 2 is used to receive the guardrail plate 9 discharged from the feeding mechanism 1 and position the guardrail plate 9. The receiving and positioning mechanism 2 has an integrally formed arc-shaped receiving structure on the side close to the feeding mechanism 1, so that the guardrail plate 9 falls into the receiving and positioning mechanism 2 along the arc-shaped receiving structure and remains vertical so that the gripping mechanism 4 can grip it.

[0044] like Figure 1 and Figure 3 As shown, the material rack 8 is set inside the zinc pot 7 to fix the guardrail 9. The material rack 8 has several material slots for accommodating the guardrail 9. There are two material racks 8.

[0045] like Figure 1 As shown, the drive device is positioned above the zinc pot 7. The drive device includes a translation mechanism 3 for driving the guardrail 9 to move horizontally and a lifting mechanism for driving the guardrail 9 to rise and fall. Since both the translation mechanism 3 and the lifting mechanism are conventional existing technologies, their specific structures will not be described in detail here. In this embodiment, because the two sets of robotic arms operate independently, a rack and pinion translation mechanism 3 can be used. The rack is mounted on the crossbeam (or frame), and the main moving trolley is slidably mounted on the crossbeam via a linear guide rail. A walking servo motor is fixedly mounted on the main moving trolley, and the walking servo motor is also connected to a gear that meshes with the rack. Two main moving trolleys are provided. Two lifting mechanisms are connected below each main moving trolley, and the two lifting mechanisms are arranged in a front-to-back direction to stably grip the guardrail 9. There are many types of lifting mechanisms; considering the working environment, this embodiment uses an electric lifting mechanism, specifically a rack and pinion type lifting mechanism, to ensure smooth and reliable operation and easy disassembly and maintenance.

[0046] like Figure 1 and Figure 2 As shown, the gripping mechanism 4 is used to grip the guardrail 9, and the gripping mechanism 4 is connected to the lifting mechanism; both the drive device and the gripping mechanism 4 are provided with two sets, and the two sets work alternately to improve work efficiency. In this embodiment, one set of robotic arms includes a main moving trolley, two lifting mechanisms and two gripping mechanisms 4; one set is mainly used to put the guardrail 9 into the zinc pot 7, and the other set is used to take out the guardrail 9 after galvanizing.

[0047] The gripping mechanism 4 includes a rotatable limiting rod 402 and a cooperating rod 403 that cooperates with the cooperating rod 403 to fix the guardrail plate 9. The bottom of the limiting rod 402 is provided with a limiting structure for limiting the guardrail plate 9.

[0048] The limiting rod 402 has a working position and a clearance position in its rotation stroke. When the limiting rod 402 is in the working position, the limiting structure at the bottom is close to the cooperating rod 403 to achieve the gripping of the guardrail plate 9. When the limiting rod 402 is in the clearance position, the limiting structure at the bottom is far away from the cooperating rod 403 to provide clearance for gripping or release the gripping of the guardrail plate 9.

[0049] In this embodiment, the limiting rod 402 is connected to the lifting mechanism via a rotating structure 401. Specifically, the rotating structure 401 includes a cylinder and a rotating rod rotatably mounted inside the cylinder. In this embodiment, the rotating rod only needs to rotate between 0-90°, and the driving structure can be a motor or pneumatic assembly. The limiting rod 402 is connected to the rotating rod by bolts, facilitating the replacement of the limiting rod 402. The mating rod 403 is bolted to the side of the cylinder.

[0050] like Figure 1 and Figure 4 As shown, the discharge mechanism 6 is located on the side of the zinc pot 7 away from the receiving and positioning mechanism 2. The discharge mechanism 6 is used to transport the galvanized guardrail 9.

[0051] The discharge mechanism 6 includes several discharge rollers, which are connected to the bearing housing via bearings and are driven by an external motor. The discharge rollers are tapered rollers to position the guardrail 9 during the conveying process.

[0052] If the guardrail 9 is overturned directly, the long-term impact can easily cause the discharge roller to deform. Therefore, in this embodiment, a buffer mechanism 5 is provided between adjacent discharge rollers to support the guardrail 9. The buffer structure includes a wedge frame and a drive cylinder for driving the wedge frame to rotate. In other embodiments, a structure such as a motor can also be used to drive the wedge frame to rotate.

[0053] The working principle of this utility model is as follows:

[0054] The guardrail panel 9 is conveyed by the feeding mechanism 1. Upon reaching the end, the guardrail panel 9 falls into the receiving and positioning mechanism 2 along its arc-shaped receiving structure and remains vertical. The robotic arm near the receiving and positioning mechanism 2 grabs the guardrail panel 9 and places it on the material rack 8 inside the zinc pot 7 for galvanizing. During the galvanizing process, the robotic arm near the receiving and positioning mechanism 2 continues to operate. After the galvanizing time is set, the robotic arm near the discharge mechanism 6 removes the guardrail panel 9. When lowering the guardrail panel 9, it first rests against the wedge frame. As the wedge frame rotates to a horizontal position, the guardrail panel 9 is laid flat on the discharge rollers and conveyed to the next process.

[0055] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
