Further, when the orthographic projection of the dust collection joint 300 on the product surface 100 is a circle, the radius range of the circle is different according to the type of the product. For example, when the product is an optical electronic product such as a lens of VR glasses, the radius of the circle may be set to 45mm to 55 mm. When the product size is larger, the radius of the circle may also increase accordingly, such as 5cm to 10 cm.

According to the dust collection method provided by the embodiment of the application, the guide surface of the dust collection joint is arranged opposite to the surface of a product, and particles on the surface of the product are uniformly guided to the dust collection channel by the guide surface, so that the particles on the surface of the product are collected. And because the guiding surface comprises the profiling part, the shape of the profiling part is the same as that of the surface of the product, so that a negative pressure area with the same shape as that of the product is formed above the surface of the product, particles on the surface of the product are uniformly sucked away, and a good dust collecting effect is achieved.
In some embodiments, the dust collecting method is used for collecting particles generated by laser cutting during the laser cutting process of the laser cutting device, so that the surface of a product after laser cutting can keep high cleanliness.
FIG. 4 shows a block flow diagram of a dust collection method in an embodiment of the present application.
Referring to fig. 4, in one embodiment, the laser cutting process includes the steps of:
step S1, moving the product to be cut to the lower part of the dust collecting joint of the dust collecting device;
step S2, lowering the dust collecting joint to a preset position;
step S3, starting a negative pressure mechanism;
step S4, starting the laser cutting device until the cutting is finished;
step S5, closing the negative pressure mechanism;
step S6, the dust collecting joint is lifted to the initial position.
The particles generated in the laser cutting process are collected through the dust collecting device, and the particles are prevented from falling to the surface of a product to influence the cleanliness of the surface of the product or influence the performance of the product.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
