Problems solved by technology

During production, there will be some non-technical defects on the surface of the paint film on some wheels. These defects often need to be picked manually. This work is a great challenge to the energy and physical strength of employees. The automated production stage requires a method that can be automatically detected. Device for sorting defective semi-finished wheels
[0003] The patent with the application number CN201910834797.8 discloses a detection method for the spraying quality of aluminum alloy wheels. This invention uses the principle of aluminum alloy material conduction, combined with the necessary multimeter for electrical engineering as a detection tool, to achieve the purpose of rapid detection. However, manual operation is still required, and errors are prone to occur during manual operation

Embodiment 1

[0039] The self-inspection method of the wheel coating line after painting includes the following steps: the height of the wheel is measured and the grating is used to detect the width of the wheel shape, and the wheel shape of the same height is screened for the first time in the wheel shape library;

[0040] After the detection height is completed, the width measuring grating starts to detect the width of the hub wheel type, and performs a second screening of the wheel hub wheel type with the same width in the wheel type library;

[0041] The centering mechanism centers the hub, and the server controls the lifting platform in the box to the specified height;

[0042] The camera in the box takes pictures of the wheel hub, and sends the captured image back to the server. The server detects the wheel shape by comparing with the master, and identifies the defects on the front and side of the wheel hub;

[0043] The laser scanner scans the inner cavity of the hub, and compares an...

Embodiment 2

[0046] The self-inspection method after painting of the wheel coating line includes the following steps:

[0047](1) The wheel hub enters the working area of ​​the self-inspection device, the height measuring grating detects the wheel width of the wheel hub, and the height measuring grating transmits the pulse signal to the PLC, and the PLC converts the pulse signal into a digital signal and then transmits it to the server. Width, and the wheel type of the same height hub is screened for the first time in the wheel type library;

[0048] (2) After the detection height is completed, the wheel hub enters the identification box, the PLC controls the track motor in the box to stop working, and the width measuring grating starts to detect the wheel width of the wheel hub. After being converted into a digital signal, it is transmitted to the server, and the server calculates the width of the wheel type, and performs a second screening of the wheel type with the same width in the whe...

Abstract

The invention belongs to the field of hub production equipment, and particularly relates to a self-inspection device and method after paint spraying of a hub coating line. The device comprises a track, wherein a height measuring grating, a width measuring grating, a centering mechanism, a box body, a stirring device and a code spraying device are sequentially arranged in the running direction of ahub, a camera, a laser scanner and a rotating mechanism are arranged on the inner top of the box body, a lifting table mechanism is arranged at the bottom in the box body, and the tail end of the track is divided into a qualified product track and a repair track. By means of the device and the method, wheel types are automatically screened for multiple times, the screening speed is accelerated, and the error rate is greatly reduced; meanwhile, the defects of the front face, the side face and the inner cavity are identified, and the integration level is high; and the qualified product and thedefective product are processed separately, and the rework operation is facilitated.

Description

technical field [0001] The invention belongs to the field of hub production equipment, and in particular relates to a self-inspection device and method for a hub coating line after painting. Background technique [0002] Automobile hubs need to go through multiple processes in the production process, and the painting process is one of the important components of the wheel hub production process. During production, there will be some non-technical defects on the surface of the paint film on some wheels. These defects often need to be picked manually. This work is a great challenge to the energy and physical strength of employees. The automated production stage requires a method that can be automatically detected. A device for sorting defective semi-finished wheels. [0003] The patent with the application number CN201910834797.8 discloses a detection method for the spraying quality of aluminum alloy wheels. This invention uses the principle of aluminum alloy material conduct...
