Description

Technical Field

[0001] The utility model relates to the field of laser processing, and in particular to a laser marking device for an electric toothbrush. Background Art

[0002] During the production process, electric toothbrushes require a laser marking machine to apply anti-counterfeiting markings to their surfaces. Laser marking for electric toothbrushes is a high-precision marking technology widely used in the production process. This system uses a laser beam to mark the toothbrush surface, thereby engraving product information such as the brand logo, model, production date, and barcode. Laser marking can effectively improve production efficiency, reduce error rates, and enhance the product's brand value and market competitiveness.

[0003] However, most of the laser marking devices used for electric toothbrushes currently have the following problems:

[0004] 1. Existing laser marking devices for electric toothbrushes are mostly installed and limited by bolts to facilitate the stability of the laser marking machine body during use. After the equipment is used for a long time, the laser will malfunction. When replacing or repairing and maintaining it, it is troublesome to disassemble it, making it inconvenient to disassemble and install the laser marking machine body conveniently.

[0005] Second, in existing laser marking devices for electric toothbrushes, during processing operations, the limiting mold is mostly installed and fixed at the conveying equipment. The mold of the toothbrush will have grooves opened according to the model. When producing different models of toothbrushes, it is inconvenient to install and replace the limiting mold.

[0006] Therefore, we have made improvements to this and proposed a laser marking device for electric toothbrushes. Utility Model Content

[0036] Example 2:

[0037] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0038] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the first spring 4 is symmetrically distributed on the left and right sides of the fixed box 3, and the first spring 4 corresponds one-to-one with the first clamping block 6 through the limiting plate 5, which can ensure that the first clamping blocks 6 on both sides are engaged in the positioning plate 8, and can be smoothly limited and installed.
