Description

Technical Field

[0001] This invention relates to the field of wheel hub sorting equipment technology, and in particular to an automatic sorting device for wheel hub inspection. Background Technology

[0002] After the wheel hub is formed, one or more inspection / testing devices will be set up at subsequent processing nodes, such as helium detectors, dynamic balancing detectors, fluorescence detectors, and surface defect visual inspection machines. Each inspection process will divide the wheel hubs into three categories: qualified products, defective products (which can be repaired), and scrap products. The traditional sorting method is to set up three conveyor lines at the output end of the inspection equipment to correspond to the three categories of products. Qualified products continue to flow down, defective products are returned to the previous process or a separate repair process for repair, and after repair, they enter the inspection again. Scrap products are sent to waste treatment equipment (usually a metal compressor or shredder).

[0003] In the inspection and rework process for defective products, missed inspections are common. A wheel hub may have multiple defects, but if only one defect is detected (especially in visual inspection), the product is stopped and sent to the rework process. This results in the returned product being found to have defects again, causing the process to waste time and production costs. Furthermore, during inspection, many defective products are not differentiated according to their severity. For example, defects on side A, side B, and side AB are all mixed together and sent to the rework process. This mixing of defects of different degrees (including quantity) prevents them from being classified for repair, hindering the rework process from allocating processing tasks as needed and severely impeding the rework process. After rework, regardless of whether the defect is on side A, side B, or side AB, it all flows into the same side A defect process, causing overlapping inspection procedures. For example, a side B defect only requires repeating the side B inspection, but in practice, it's repeated from the beginning, greatly reducing inspection efficiency. Therefore, there is an urgent need for a scientifically sound and efficient automatic sorting device for wheel hub inspection that improves inspection and rework efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic sorting device for wheel hub inspection, so as to solve the problems of program idling, program overlap and obstruction of the rework process in the existing wheel hub inspection and rework process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic sorting device for wheel hub inspection includes: A-side inspection mechanism, which is used to inspect appearance quality defects on one side of the wheel hub; B-side inspection mechanism, which is used to detect appearance quality defects on the other side of the wheel hub; A flipping and transfer machine, which flips the wheel hub of the A-side inspection mechanism and transfers it to the B-side inspection mechanism; The waste shredder mechanism is connected to the waste discharge ports of the A-side detection mechanism and the B-side detection mechanism respectively; A trimming mechanism, wherein the two feed ends of the trimming mechanism are respectively connected to the defect discharge ends of the A-side inspection mechanism and the B-side inspection mechanism, and the two discharge ends of the trimming mechanism are respectively connected to the feed ends of the A-side inspection mechanism and the B-side inspection mechanism. The packaging mechanism has its inlet end connected to the qualified outlet end of the B-side inspection mechanism.

[0006] A further technical solution is that the feeding ends of the waste crusher mechanism, the trimming mechanism, and the packaging mechanism are all equipped with a pushing component, which consists of a pushing cylinder and an arc-shaped push plate disposed on the power output end of the pushing cylinder.

[0007] A further technical solution is: the A-side inspection mechanism and the B-side inspection mechanism have the same structure, both including an inspection conveyor, a vision inspection device and a rotating gripper. The vision inspection device is set on the conveying path of the inspection conveyor, and the rotating gripper is set on one side of the vision inspection device. The rotating gripper is used to pick up and put down the hub between the inspection conveyor and the vision inspection device.

[0008] A further technical solution is as follows: the rotating gripper includes a connecting plate, a hollow shaft, a rotating air box, a rotating plate, and gripping components. The connecting plate is connected to the working end of the robot arm. The hollow shaft is vertically mounted on the connecting plate. The rotating air box and the rotating plate are interconnected and rotatably mounted on the hollow shaft. Multiple gripping components are arranged in a circular array and uniformly on the outer circumference of the rotating plate. The air inlet of the hollow shaft, the rotating air box, and the drive source of the gripping components form a one-way air path. The drive source of the gripping components is equipped with a solenoid valve that communicates with the one-way air path. A motor that drives the rotating plate is mounted on the connecting plate.

[0009] A further technical solution is as follows: the clamping assembly includes a swing arm, a bidirectional cylinder, and an anti-slip clamp. The swing arms are symmetrically arranged on the outer peripheral surface of the rotating plate, and one of the swing arms is rotatably connected to the outer peripheral surface of the rotating plate. The two ends of the bidirectional cylinder are respectively hinged to the two swing arms. The two air inlets of the bidirectional cylinder are connected to the air outlet of the rotating air box through the solenoid valve. The anti-slip clamp is slidably arranged on the inner side of the swing arm, and the anti-slip clamp is rotatably connected to the swing arm through a positioning pin.

[0010] A further technical solution is: the scrap crusher mechanism includes a scrap conveyor and a metal crusher, the feed end of the scrap conveyor is connected to the scrap discharge port of the A-side detection mechanism and the B-side detection mechanism, and the metal crusher is arranged on the conveying path of the scrap conveyor.

[0011] A further technical solution is: the trimming mechanism consists of a manual inspection table and a machining equipment located at the rear end of the manual inspection table, and the two feed ends of the manual inspection table are respectively connected to the defect discharge ends of the A-side inspection mechanism and the B-side inspection mechanism.

[0012] A further technical solution is as follows: the packaging mechanism includes a qualified product conveyor line, a carton conveyor line, and a material handling robot. The inlet end of the qualified product conveyor line is connected to the qualified product outlet end of the B-side inspection mechanism. The carton conveyor line is connected to the qualified product conveyor line. The material handling robot is located at the intersection of the qualified product conveyor line and the carton conveyor line.

[0013] A further technical solution is that a marking machine is provided at the defect discharge end of the A-side inspection mechanism and the B-side inspection mechanism, and at the feed end of the packaging mechanism.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes an automatic sorting device for wheel hub inspection. The device divides wheel hubs into A and B sides for inspection, categorizing the inspection results into five types: qualified, A-side defect, B-side defect, AB-side defect, and scrap. It also provides three types of defect detection, allowing for seamless conversion and program continuity between the three inspection results and rework processes. If a defect is detected on the A side, the wheel hub can proceed to the rework process or, for flow control considerations, directly to the B-side inspection process. If a defect is detected on the B side, after rework, the inspection process can continue, directly repeating the B-side inspection. This device prevents missed inspections and program idling and overlap, and by classifying and processing wheel hub A-side, B-side, and AB-side defects, it greatly improves inspection and rework efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0026] This implementation example Figure 1 As shown, an automatic sorting device for wheel hub inspection includes: A-side inspection mechanism 1 is used to inspect the appearance quality defects on one side of the wheel hub. B-side inspection mechanism 2 is used to inspect the appearance quality defects on the other side of the wheel hub. The flipping and transferring machine 3 flips the wheel hub of the A-side inspection mechanism 1 and transfers it to the B-side inspection mechanism 2; The waste crushing mechanism 4 is connected to the waste discharge ports of the A-side detection mechanism 1 and the B-side detection mechanism 2 respectively. The trimming mechanism 5 has two feed ends that are connected to the defect discharge ends of the A-side inspection mechanism 1 and the B-side inspection mechanism 2, respectively, and two discharge ends that are connected to the feed ends of the A-side inspection mechanism 1 and the B-side inspection mechanism 2, respectively. Packaging mechanism 6, the feeding end of packaging mechanism 6 is connected to the qualified discharge end of B-side inspection mechanism 2.

[0027] Taking the visual inspection process for surface defects as an example, this device addresses the issue that car wheel hubs are typically regular, flat cylinders. Considering the appearance quality of both sides of the hub, they are usually placed horizontally on visual inspection equipment for inspection. This device inspects both sides of the hub separately, refining the previously generalized defect inspection results. Figure 1The inspection process can yield five results: qualified product, A-side defect, B-side defect, AB-side defect, and scrapped product. The wheel hub first enters the A-side inspection mechanism 1, where two results are obtained: A-qualified and A-defective.

[0028] The following are methods for handling the results of the first test: A qualified wheel hubs are flipped over by the flipping and transferring machine 3 and then transported to the B-side inspection mechanism 2 for a second inspection. There are two possible results: AB qualified and B defective. AB qualified hubs proceed to the packaging mechanism 6 for packaging, while B defective hubs proceed to the repair mechanism 5. After repair mechanism 5 completes its processing, it directly reconnects to the B-side inspection mechanism 2 for re-inspection of the B-side, without having to go through both the A and B-side inspection procedures, thus avoiding process overlap.

[0029] For wheel hubs with defect A, there are two possible flow paths based on the site conditions. If the rework process is not under significant pressure, the defective wheel hub is directly transferred to the finishing mechanism 5. After rework, it re-enters the A-side inspection mechanism 1 for further inspection. Conversely, if the defective wheel hub continues to the B-side inspection mechanism 2, both A and B sides are inspected, resulting in two possible inspection results: AB-side defect or A-side defect. Both A-side and AB-side defects require rework. At this point, the handling depends on the actual situation. A-side defects are easier to rework and take less time, so they can be processed first. After processing, they re-enter the A-side inspection mechanism 1 for further inspection. Once the A-side is defect-free, it is considered a qualified product, which helps to quickly increase the number of qualified products. AB-side defects are time-consuming and difficult to rework, so they can be considered as an exception to normal operations and processed uniformly during off-peak periods. This scientific and reasonable handling method prevents process idling and overlap, as well as inefficiencies caused by unreasonable defect classification and unscientific rework arrangements. The aim is to improve process efficiency and reduce costs.

[0030] Preferably, the feeding ends of the waste crusher mechanism 4, the trimming mechanism 5 and the packaging mechanism 6 are all provided with a pushing component 7, which consists of a pushing cylinder and an arc-shaped push plate provided on the power output end of the pushing cylinder.

The rotating gripper 13 is used to pick up and put down the hub between the inspection conveyor 1 and the vision inspection device 12.

[0033] The rotating gripper 13 has three stations, corresponding to the two ends of the inspection conveyor 1 and the inspection station of the vision inspection device 12, respectively, so as to achieve a coordinated and continuous wheel hub picking and placing and transferring effect. Example

[0034] Based on the above embodiments, this embodiment, for example Figure 2 and Figure 3 As shown, the rotating gripper 13 includes a connecting plate 131, a hollow shaft 132, a rotating air box 133, a rotating plate 134, and a gripping assembly 135. The connecting plate 131 is connected to the working end of the robot arm. The hollow shaft 132 is vertically mounted on the connecting plate 131. The rotating air box 133 and the rotating plate 134 are interconnected and rotatably mounted on the hollow shaft 132. Multiple gripping assemblies 135 are arranged in a circular array and evenly distributed on the outer circumference of the rotating plate 134. The air inlet of the hollow shaft 132, the rotating air box 133, and the drive source of the gripping assembly 135 form a unidirectional air path. The drive source of the gripping assembly 135 is equipped with a solenoid valve that communicates with the unidirectional air path. The connecting plate 131 is equipped with a motor that drives the rotating plate 134.

[0035] The motor drives the rotary air box 133 and the rotary plate 134 to rotate.

It is used to inspect the hubs at both ends of the conveyor 1 and the inspection station of the vision inspection equipment 12 for picking up and placing. An external air source supplies compressed air to the hollow shaft 132. The rotary air box 133 and the hollow shaft 132 are sealed and rotated together by a rotary dynamic seal. The compressed air of the hollow shaft 132 passes through the rotary air box 133 and supplies air to the drive source of the clamping components 135 without affecting the rotation of the clamping components 135.

It uses compressed air to generate pressure in both directions to achieve the reciprocating motion of the piston, and is widely used in industrial automation, mechanical control, and other fields. External air enters the double-acting cylinder 1352 through the hollow shaft 132 and the rotating air box 133. The double-acting cylinder 1352, along with two swing arms 1351, unfolds or merges to achieve the operation of loosening and releasing the wheel hub.

[0039] Wheel hubs with major quality problems exceeding the defects on side A or side B (scrap products) can be pushed onto the scrap conveyor 41 by the pusher assembly 7, and then transported to the metal crusher 42 (such as a hydraulic crusher or jaw crusher) for crushing, so as to facilitate remelting and recasting.

[0041] Minor defects in the wheel hub or problems that are inconvenient to repair by machine can be repaired manually on the manual inspection table 51, which is convenient and quick. If it cannot be handled manually or is more suitable for machine handling, it can be directly sent to the machining equipment 52 for processing and repair.
