Problems solved by technology

[0003] In the process of automobile production or post-maintenance process, it is necessary to detect the defects of the automobile paint surface, so as to repair the defects of the automobile paint surface. The work of automatic detection not only seriously affects the work efficiency, but also increases the work intensity of the staff; at the same time, the automobile paint surface defect detection device in the prior art cannot be applied to the paint surface defect detection of automobiles of different sizes, and the detection The accuracy is low, and there is a problem of frequent missed inspections; in addition, the car paint surface defect detection device in the prior art has the problem that the staff cannot understand its working status in real time, often because the staff does not understand its working status It affects the smooth development of the detection of car paint surface defects, and also leads to low work efficiency

Embodiment 1

[0045] Such as Figure 1-Figure 2 As shown, a vehicle paint surface defect detection device based on intelligent sensing and machine vision includes a square hollow base 1, a gantry-shaped fixing frame 2, a transmission mechanism 3, two sets of side detection mechanisms 5, a top detection mechanism 6, two A set of lighting mechanism 7 and control mechanism 4, the square hollow base 1 is arranged horizontally, and a square through groove 10 is reserved in the center on the top wall of the square hollow base 1, and the gantry-shaped fixing frame 2 is vertically and fixedly Installed on the top of the square hollow base 1, and the gantry-shaped fixing frame 2 is set across the square slot 10, the transmission mechanism 3 is fixedly installed inside the square hollow base 1, and the transmission The upper part of the mechanism 3 runs through the square channel 10 and is arranged flush with the upper surface of the top wall of the square hollow base 1, and two sets of side detectio...

Embodiment 2

[0054] The difference from Example 1 is that a protective layer is also provided on the surface of the square hollow base 1, and the protective layer is prepared by the following method:

[0055] Take the following raw materials and weigh them by weight: 20-30 parts of epoxy resin, 10-12 parts of talc powder, 11-13 parts of aluminum oxide powder, 11-13 parts of chromium trioxide powder, 11-13 parts of phenolic resin, 8-10 parts of cobalt naphthenate, 3-5 parts of DMP-30 accelerator and 35-55 parts of water;

[0056] S1, adding epoxy resin, talcum powder, aluminum oxide powder, chromium oxide powder and phenolic resin into a ball mill for grinding until the particle diameter is not greater than 100nm, so as to prepare a mixed powder material;

[0057] S2. Add the mixed powder material prepared in step S1, cobalt naphthenate, DMP-30 accelerator and water into the reaction kettle and stir for 25-35min, the stirring speed is 800-1000r / min, and the temperature is 80-100°C , when t...

Abstract

The invention discloses a vehicle paint surface defect detection device based on intelligent sensing and machine vision. The device comprises a square hollow base, a gantry-shaped fixing frame, a conveying mechanism, two sets of side detection mechanisms, a top detection mechanism, two sets of illumination mechanisms and a control mechanism. The square hollow base is horizontally arranged, whereina square through groove is reserved in the middle of the top wall of the square hollow base, the gantry-shaped fixing frame is vertically and fixedly installed at the top of the square hollow base, the gantry-shaped fixing frame stretches across the square through groove, and the conveying mechanism is fixedly installed in the square hollow base. The automobile paint surface flaw detection devicecan be used to complete automatic detection of automobile paint surface flaws, working efficiency can be greatly improved, working intensity of workers can be effectively reduced, the device can be suitable for paint surface flaw detection of automobiles of different sizes, detection accuracy can be ensured, and missing detection can be effectively missed.

Description

technical field [0001] The invention relates to the technical field of automobile paint surface detection, in particular to a vehicle paint surface flaw detection device based on intelligent sensing and machine vision. Background technique [0002] my country's latest national standard "Terms and Definitions of Vehicles and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-loaded vehicle driven by power with 4 or more wheels, mainly used Used for: carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. [0003] In the process of automobile production or post-maintenance process, it is necessary to detect the defects of the automobile paint surface, so as to repair the defects of the automobile paint surface. The work of automatic detection not only seriously affects the work efficiency, but also increases the work intensity of the staff; at the same time, the automobile paint surface defect detec...
