Description

Technical Field

[0001] The invention relates to the technical field of table tennis racket processing equipment, and in particular to a double-stage table tennis racket labeling device and a labeling method. Background Art

[0002] In the prior art, table tennis is a widely used sport, and a good table tennis racket is particularly important in table tennis. Table tennis rackets are mostly made of wooden materials. After they are manufactured, they need to be labeled for easy identification. The existing labeling methods of table tennis rackets all adopt traditional manual labeling methods. Due to the limitations of labor costs, efficiency and accuracy, they can no longer meet the needs of modern industrial production. In the process of manual labeling of table tennis rackets, workers need to operate each product one by one, which is not only time-consuming and labor-intensive, but also due to the interference of human factors, it is easy to distort the label and affect the aesthetics of the product, resulting in the product quality of table tennis rackets that are manually labeled being difficult to effectively guarantee.

[0003] The Chinese invention patent with application number: 202410464352.6 discloses an automatic labeling mechanism, which includes: a feeding module, including a material collection and unloading component and a lower visual component, the material collection and unloading component includes a feeding negative pressure platform, a reeling roller, a plurality of tension rollers, and a reeling roller, the feeding negative pressure platform is provided with a hole for connecting a vacuum device, and the other end thereof forms an acute angle, and a plurality of tension rollers are used to make the coil close to the acute angle, and the lower visual component includes a lower camera for photographing and positioning the label above it that has escaped from the coil; a three-axis labeling module, including an X-axis component, a Y-axis component, a Z-axis component, a material picking component, and an upper visual component, the material picking component includes a material suction plate, a slide cylinder that drives the material suction plate to move along the Z-axis direction, and a rotating motor that drives the material suction plate to rotate along the R-axis, and the upper visual component includes an upper camera for photographing and positioning the label below it that has escaped from the coil. However, this type of automatic labeling mechanism can only label flat products. Since a table tennis racket is a three-dimensional structure, the thickness of the grip is inconsistent with the thickness of the racket surface. Therefore, this type of automatic labeling mechanism cannot automatically label a table tennis racket. This type of automatic labeling mechanism does not have a buffer structure, which causes deep marks on the product when it is labeled, affecting the product quality. In addition, this type of labeling mechanism cannot meet the double-sided labeling requirements of the product. Summary of the invention
