Description

Technical Field

[0001] The utility model relates to the technical field of engraving devices, in particular to a movable needle-type engraving device. Background Art

[0002] Die-casting products are mass-produced due to factors such as the cost-effectiveness of mass production. Therefore, product information management and identification of multiple varieties of products are particularly important. After the die-casting products are taken out of the die-casting machine, they must first be engraved with a unique identification code on the product using an engraving device before the next step of processing. However, a die-casting machine can often produce different types of products based on different molds. In this case, the engraving device also needs to meet the needs of flexible production so that it can correspond to multiple types of die-casting products.

[0003] A Chinese patent (authorization number CN112658492A) discloses a laser marking device. Although it realizes the effect of quickly clamping the workpiece by placing the sliding block along the active groove distributed in a cross shape and sliding and adjusting the position of the clamping assembly according to the shape of the special-shaped part, and then raising the relative height of the pressing sheet relative to the base according to the thickness of the special-shaped part, it does not solve the method of fixed-point marking generally used in the industry. When this method is used, the laser marking machine is marking the workpiece, and the downward movement position of the laser marking machine depends entirely on the experience of the workers, which can easily cause the laser marking machine to collide with the workpiece, thereby causing damage to the laser marking machine or the workpiece, further affecting the efficiency of workpiece marking; at the same time, it is not convenient to accurately mark the workpiece, thereby affecting the effect of workpiece marking; therefore, the above problems need to be solved.
