Abstract
Description
Technical Field
[0001] The invention relates to the technical field of detecting the size and appearance of aluminum parts, and in particular to a detection device and a working method for automatically detecting aluminum parts. Background Art
[0002] The aluminum parts produced by a workshop are rectangular in shape, with multiple through holes. After a batch of aluminum parts are produced in the workshop, the process requires the inspection of the dimensions of each aluminum part, and the appearance of the aluminum parts [because there are scraps or oil stains attached to the top surface of the aluminum parts, so the appearance of the aluminum parts needs to be inspected], so as to select the finished aluminum parts whose dimensions and appearance meet the design requirements, and eliminate the unqualified aluminum parts whose dimensions or appearance do not meet the design requirements.
[0003] The method for testing aluminum parts in the workshop is: S1. A worker takes out an aluminum part to be inspected and measures the dimensions of the four sides with a caliper. After measurement, if it is found that the external dimensions of the aluminum part do not meet the design requirements, the worker determines that the aluminum part is an unqualified aluminum part and removes the unqualified aluminum part into a waste basket A; after measurement, if it is found that the external dimensions of the aluminum part meet the design requirements, the worker determines that the aluminum part is a semi-finished product; S2. The worker places the semi-finished product directly under the CCD camera, and uses the CCD lens to detect whether there is waste or oil on the top surface of the semi-finished product. After the detection, if it is found that the appearance of the semi-finished product does not meet the design requirements, the worker determines that the semi-finished product is an unqualified aluminum part, and the worker removes the unqualified aluminum part into the waste basket B; after the detection, if it is found that the appearance of the semi-finished product meets the design requirements, the worker determines that the semi-finished product is a finished aluminum part, and the worker puts the finished aluminum part into the finished product basket, thereby completing the detection of one aluminum part; S3, the worker repeats steps S1 to S2 multiple times, and can continuously inspect multiple aluminum parts; S4. After inspection, if the waste basket A contains unqualified aluminum parts whose sizes do not meet the design requirements, the workers will transfer the unqualified aluminum parts in the waste basket A to the rework process, and the workers will reprocess the unqualified aluminum parts whose sizes do not meet the design requirements; while the waste basket B contains unqualified aluminum parts whose appearance does not meet the design requirements, the workers will transfer the unqualified aluminum parts in the waste basket B to the cleaning process, and the workers will clean the unqualified aluminum parts again through cleaning equipment.
[0004] However, although the method used in the workshop can detect multiple aluminum parts, it still has the following technical defects: I. In step S1, it is necessary to use a caliper to measure the dimensions of the four sides of the aluminum part, and there are many measuring steps, which undoubtedly increases the measuring steps, thereby increasing the detection time of the aluminum part, thereby reducing the detection efficiency of the aluminum part.
[0005] II. In step S4, unqualified aluminum parts whose sizes do not meet the design requirements need to be manually removed into the waste basket A, and then the unqualified aluminum parts whose sizes do not meet the design requirements need to be manually moved to the rework process, which not only increases the work intensity of the workers, but also increases the inspection time for subsequent aluminum parts, thereby reducing the production efficiency of aluminum parts. In addition, unqualified aluminum parts whose appearance does not meet the design requirements need to be manually removed into the waste basket B, and then the unqualified aluminum parts whose appearance does not meet the design requirements need to be manually moved to the cleaning process, which not only increases the work intensity of the workers, but also increases the inspection time for subsequent aluminum parts, thereby reducing the production efficiency of aluminum parts.

Detection of the dimensions of the four sides of the aluminum part: the stepper motor is controlled to start, the stepper motor drives the turntable 2 to rotate, and the turntable 2 drives the carrier 3 to rotate synchronously. When the turntable 2 rotates to the set angle, the controller controls the stepper motor to turn off. At this time, the aluminum part just enters the detection position of the dimension detection mechanism 5, that is, the aluminum part is just under each laser displacement sensor 25 of the dimension detection mechanism 5, and the laser displacement sensor 25 measures the dimensions of the four sides of the aluminum part; After measurement, if it is found that the external dimensions of the aluminum part do not meet the design requirements, the worker will determine that the aluminum part is unqualified.
