Description

Technical Field

[0001] The present invention relates to a detection device and method for the outer contour of a razor, belonging to the technical field of automatic detection. Background Art

[0002] As a daily necessity, the appearance quality of a razor directly affects the user experience. The appearance detection of traditional manual razors mainly relies on manual visual inspection or simple tool measurement. For example, tools such as vernier calipers are used to locally measure the blade thickness and the cutter head size. However, such methods are inefficient and cannot comprehensively evaluate the accuracy of complex structures (such as the fit between the blade and the protective rubber strip, etc.). Especially as the design of manual razors becomes increasingly complex, such as the multi-link structure with an adjustable cutter head angle, the special-shaped handle with a fluorescent mark, and the embedded design of the blade and the skin protection soft rubber, traditional detection means are difficult to quantitatively analyze their spatial parameters and dynamic adaptability. In addition, the correlation between the sharpness of the blade and the external dimensions has not been systematically detected. For example, micron-level errors in the blade edge may lead to a decrease in shaving efficiency or skin scratches, while traditional methods only focus on macroscopic dimensions and ignore the automated evaluation of microscopic topography, making it difficult to meet the requirements of modern production. Machine vision technology has the advantages of non-contact, high precision, high efficiency, etc., and is gradually applied to the field of industrial detection. Summary of the Invention

[0003] The present invention discloses a detection device and method for the outer contour of a razor, aiming to solve the problems of low efficiency and strong subjectivity of traditional manual detection methods.

A hole matching with the main shaft of the stepping motor is opened in the first fixing block. The top of the Z-shaped bracket is connected to the first fixing block through a pin shaft, and a displacement sensor is inserted at the top of the Z-shaped bracket. A chuck mechanism is provided on the upper part of the sliding block.

[0005] Further, the chuck mechanism further includes a chuck base and two groups of symmetric chucks. A limiting block is inserted into the chuck, clamping grooves are provided on both sides inside the chuck, and inserting blocks are provided on both sides outside the limiting block.
