DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The terms "including" and "having" and any variations thereof mentioned in the embodiments of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0021] The embodiment of the present invention provides a device for detecting wheel hub defects, such as Figure 1 As shown, it includes an annular conveyor belt 1, a wheel hub detection fixing seat 2, a wheel hub 3, a distance measuring sensor 4, a telescopic rod 5, a CCD industrial camera 6, a rotating motor 7, a circulating track 8, a detection support frame 9, a wheel hub input conveyor belt 10, a No. 1 wheel hub handling robot 11, a wheel hub output conveyor belt 12, and a No. 2 wheel hub handling robot 13.

[0022] The wheel hub 3 is installed on the circular conveyor belt 1 during the detection process, and plays the role of moving the wheel hub 3; the wheel hub detection fixing seat 2 is evenly installed on the circular conveyor belt 1, and plays the role of fixing the wheel hub 3 for detection; the circulating track 8 is installed above the circular conveyor belt 1, and plays a guiding role; the telescopic rod 5 is installed on the rotating motor 7, and plays a telescopic role; the rotating motor 7 is installed on the circulating track 8, and plays the role of rotating the telescopic rod 5 and circulating detection and movement; the distance measurement sensor 4 and the CCD industrial camera 6 are respectively installed on both sides of the detection support frame 9, and play the role of wheel hub 3 defect detection; the wheel hub input conveyor belt 10 and the wheel hub output conveyor belt 12 are respectively installed on the left and right sides of the circular conveyor belt 1, and play the role of wheel hub 3 transmission; the No. 1 wheel hub handling robot 11 and the No. 2 wheel hub handling robot 13 are respectively installed on both sides of the wheel hub input conveyor belt 10 and the wheel hub output conveyor belt 12, and play the role of handling the wheel hub 3.

[0023] In a possible implementation, the circulating track 8 can realize follow-up detection of defects of the wheel hub 3 .

[0024] In a possible implementation, the annular conveyor belt 1 can realize a secondary replacement re-inspection of the wheel hub 3 to avoid misdetection of defects of the wheel hub 3 due to damage to the detection equipment, etc., and can improve the accuracy of defect detection of the wheel hub 3. At the same time, the detection equipment can be self-checked for damage by replacement detection, and damage to the detection equipment can be discovered at the first time to avoid large economic losses.

[0025] The working principle of the detection method of the device applied to wheel hub defect detection includes the following steps:

[0026] (a) Normal inspection of wheel hub 3: During normal inspection, that is, when the inspection device does not detect defects in wheel hub 3, the working process of the wheel hub 3 defect inspection device is as follows. When the wheel hub 3 is transmitted to the bottom of wheel hub handling robot 11 through the wheel hub input conveyor belt 10, the wheel hub handling robot 11 transports the wheel hub 3 to the wheel hub inspection fixed seat 2 on the circular conveyor belt 1, and performs inspection operations on three wheel hubs 3 at a time on the circular conveyor belt 1. When the wheel hub 3 is fixed to the wheel hub inspection fixed seat 2, the circular track 8 drives the rotating motor 7 to move, moves to the fixed position of the wheel hub 3 and moves at the same speed as the wheel hub 3 to perform follow-up inspection of the wheel hub 3. When the inspection of the three wheel hubs 3 is completed and the inspection is determined to be defective, the wheel hub 3 is inspected according to Figure 2 When the wheel hub 3 is transported to the junction of the annular conveyor belt 1 and the hub output conveyor belt 12, the No. 2 hub transport robot 13 transports the inspected hub 3 to the hub output conveyor belt 12 for subsequent palletizing. When the hub 3 is inspected normally, the hub 3 inspection method is shown in Figure 3 The three detection devices ABC sequentially detect the No. 1-2-3 wheel hubs 3 fixed on the wheel hub detection fixing seat 2 until the detection is completed.

[0027] (b) Re-inspection of wheel hub 3 defects: When the detection device detects that at least one of the three wheel hubs 3 has a defect, the re-inspection procedure will be started, and the detection device and the wheel hub 3 will be exchanged for detection, and the wheel hub 3 will be re-identified to see if it has the detected defect, so as to confirm the defective wheel hub 3 again and avoid misdetection due to damage to the detection device. The re-inspection process is as follows: When the detection device detects that the wheel hub 3 has a defect, the movement path of the wheel hub 3 will be changed according to Figure 4 The circular conveyor belt 1 drives the hub 3 to move faster, and the C detection device quickly moves from the detection head end to the detection end through the circular track 8. The hub 3 will be re-checked by changing the machine. Figure 5The three CAB inspection devices inspect wheel hubs 3 No. 1-2-3 respectively in the inspection sequence, realizing the re-inspection operation of wheel hub 3. The re-inspection operation performs secondary defect inspection on wheel hub 3 to improve the inspection accuracy, and at the same time, the damage assessment of the inspection equipment can be carried out to find out whether the inspection equipment is damaged in the first time, thereby reducing economic losses.

[0028] (c) Specific implementation of wheel hub 3 defect detection: When the wheel hub 3 is fixed on the wheel hub detection fixing seat 2 on the ring conveyor 1, the detection equipment will run at the same speed as the wheel hub 3. After the telescopic rod 5 starts to stretch and descend to reach the specified detection position, the rotating motor 7 starts to run, driving the distance measuring sensor 5 and the CCD industrial camera 6 to rotate around the wheel hub 3 to be detected, so as to detect the coaxiality and surface defect degree of the wheel hub 3.
