Description

Technical Field

[0001] This utility model relates to the technical field of height detection devices, specifically to an automatic detection device for product placement height. Background Technology

[0002] In mass production scenarios in manufacturing, products are often carried, transferred, and stored using trays. During actual production, products are prone to warping, skewing, and other morphological deviations due to material characteristics and processing techniques. When multiple trays are stacked, deformed products are prone to friction and collision with the upper trays, resulting in surface abrasions and affecting product quality. At the same time, when multiple products of similar thickness are produced simultaneously, it is difficult for humans to accurately distinguish them, easily leading to material mixing problems. This not only increases subsequent sorting costs but may also cause downstream assembly failures.

[0003] The prior art discloses a patent with publication number CN219178493U. This solution includes an inclined laser scanning head that can scan the product by moving horizontally. A material transfer mechanism can move the product located on the turntable to a packaging mechanism, which can package the product. The laser detection has high accuracy and high efficiency, thereby improving the subsequent packaging quality. Furthermore, the various mechanisms cooperate with each other to achieve automatic feeding, detection, and packaging, reducing manpower and improving work efficiency and quality.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, the detection accuracy is low. Manual identification is easily affected by subjective factors, making it difficult to accurately judge the degree of product warping and material mixing, especially for products with similar thickness, where the misjudgment rate is high.

[0006] Second, the testing efficiency is low. Manual testing is time-consuming and cannot meet the high-efficiency requirements of mass production.

[0007] Third, there is the risk of product damage. During manual inspection, the product may be touched, or the product may be damaged by mutual friction due to warping when the trays are stacked, which may affect the product quality.

[0008] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
