Technical Field

The invention belongs to the technical field of automobile parts, and particularly relates to a visual detection system for assembling an automobile fuse box.

Background

An automobile fuse box, also called a fuse box, is a box for installing automobile fuses, and if an engine is compared with the heart of an automobile, the automobile fuse box is the central nerve of the automobile. The automobile fuse box is responsible for transmitting driving information to each part of an automobile body, is a key part in an automobile electronic control element, and is also one of parts which have higher technical content and strict technological requirements in the automobile body.

The automobile fuse box can involve the installation of the rupture discs and the relays with different specifications and different colors in the assembling process, and the specifications and the number of the rupture discs and the relays are more. In addition, each fuse in the automobile fuse box has the function of protecting a corresponding circuit, and fuses with current values matched with loads are installed on each path according to actual conditions, so that the fuses at corresponding positions cannot be inserted in a staggered mode, otherwise, devices are burnt, or some functions cannot be used normally. Therefore, after the components in the automobile safety box are installed, strict detection is required to prevent the installation area from being neglected and misassembled.

The existing detection modes mainly comprise manual detection and automatic detection; manual detection is that detection is carried out in a manual mode; the automatic detection is carried out in an image identification mode, and the principle is that a standard image is set in advance, and after the image of the fuse box to be detected is collected, whether the fuse box is assembled correctly is judged in an image analysis and comparison mode.

However, the fuse box has various types, and even if the shells are the same, the installation modes of the internal elements of the fuse box have no small difference. When a plurality of fuse boxes need to be detected in a short time, fatigue and errors easily occur in manual detection, and the detection effect is not ideal. And automatic detection needs to be frequently set for the system to match with distribution boxes of different models, so that the efficiency is low.

Therefore, a visual inspection system for automobile fuse box assembly is needed, which can inspect fuse boxes with various specifications in a short time and with high efficiency.

Disclosure of Invention

The invention aims to provide a visual detection system for assembling automobile fuse boxes, which can detect fuse boxes with various specifications in a short time with high efficiency.

The basic scheme provided by the invention is as follows:

a visual inspection system for an automotive fuse block assembly, comprising:

the label unit is used for marking a type label on the fuse box, and the content of the type label comprises a type number;

the storage unit is used for storing standard images of various types of numbered fuse boxes;

the identity acquisition unit is used for acquiring the type number of the fuse box through the type label and matching the corresponding standard image according to the type number;

the acquisition unit is used for acquiring image information of the fuse box;

the processing unit is used for carrying out graphic analysis on the acquired image information according to the matched standard image;

and the display unit is used for displaying the analysis result.

Description of the nouns: the standard image, i.e., the image when all components inside the fuse box are properly installed.

Basic scheme theory of operation and beneficial effect:

the type label is marked on the fuse box through the label unit, and the type of the fuse box and the installation mode of the internal elements are determined in advance. On one hand, the standard image is convenient to match when the fuse box is detected after the fuse box is installed, and on the other hand, the type of the fuse box can be known by workers conveniently.

After the internal element of the fuse box is installed, the identity obtaining unit obtains the type number of the fuse box through the identity type label on the fuse box, and matches a corresponding standard graph from the storage unit according to the type number. And then, the acquisition unit acquires the image information of the fuse box, and the processing unit performs graphic analysis on the acquired image information according to the matched standard image to judge whether the internal elements of the fuse box are completely installed correctly.

Compared with the prior art, the system can detect the fuse boxes with various specifications in a short time with higher efficiency.

Further, the processing unit is also used for marking the abnormal area with color when the analysis result is that the abnormal area exists.

After the color marking, the worker can visually know the abnormal area conveniently.

Further, when the processing unit marks the abnormal region with a color, the color of the mark is red.

Compared with other colors, the red color is more striking, so that the worker can quickly and accurately know the abnormal installation area.

Further, the safe box printing device further comprises a printing unit used for printing the safe box image after the color marking.

When the abnormal area is larger/more, the worker can print the detection result after the color marking through the printing unit, and then the correction is carried out in contrast, so that the correction effect is ensured.

And the processing unit is used for analyzing the abnormal condition of the object to be detected and sending a prompt to the user.

When the safety box is abnormally installed, the attention of workers can be aroused through the prompt of the prompt unit, and the internal installation structure of the safety box is timely modified.

Furthermore, the processing unit is also used for carrying out quantity statistical analysis, and the prompting unit is also used for sending out an alarm when the detected quantity is greater than N and the abnormal ratio is greater than M.

If the abnormal ratio is larger than M, the ratio of the abnormal conditions (such as wrong loading and missing loading) is higher, and the detection number is larger than N, the detection base number is ensured, and the condition of invalid alarm caused by less statistical number is prevented. Thus, when the number of detections is greater than N and the abnormal ratio is greater than M, it is described that the detected fuse box does have a problem in terms of installation, and therefore an alarm is given to prompt a manager to pay attention to the situation and strengthen quality supervision of installation. The specific values of M and N can be set by those skilled in the art according to the production scale and the severity of the inspection.

Further, the storage unit is also used for storing the detection result; the device also comprises a statistical analysis unit used for carrying out statistical analysis on the detection result.

Due to the arrangement, the worker can perform statistical analysis on the fuse box model which is easy to install wrongly, the position area which is easy to install wrongly and the like, can pay more attention during subsequent installation, and reduces the subsequent correction amount.

Further, the content of the type tag also includes a processing group; the identity acquisition unit is also used for acquiring processing group information; the storage unit stores the detection result and the processing group in an information-related manner.

The content of the type tag also includes a tooling team, such that after the manufacturing plan, the tooling team for the fuse box can be designated while the fuse box is being classified. The storage unit stores the detection result and the processing groups in an associated mode, so that on one hand, responsibility tracing is facilitated, the processing groups can correct the fuse boxes with the abnormal conditions, and on the other hand, performance statistics can be conveniently performed on the processing groups.

Further, the type label is a two-dimensional code type label.

The technology of the two-dimensional code type label is mature, and the identification mode is simple. Compared with RFID and other types of tags, the two-dimensional code type tag is lower in cost.
