Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and in particular to a laser marking dust extraction tube. Background Technology

[0002] During the manufacturing process of metal products, QR codes or barcodes containing production information need to be affixed to the bottom. Since laser marking mechanisms emit laser light upwards from below the product, dust is generated on the parts of the product that are etched away by the laser during the marking process. Over time, this dust accumulates on the surface of the laser marking mechanism, affecting laser emission, marking, and ultimately, product manufacturing. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a laser marking dust extraction tube, which solves the problem that excessive dust accumulation during the laser marking process can affect the optical path of the laser.

[0004] To achieve the above objectives, the technical solution of this utility model is a laser-marked dust extraction tube, comprising a dust extraction tube body for extracting dust, a dust extraction section formed at the front end of the dust extraction tube body, a dust extraction section for connecting to a dust extraction mechanism at the rear end of the dust extraction tube body, a dust extraction chamber inside the dust extraction section, the dust extraction chamber communicating with the interior of the dust extraction tube body, a through hole in the middle of the dust extraction section to facilitate laser penetration, and a notch communicating with the dust extraction chamber on the inner wall of the through hole.

[0005] Preferably, the top of the dust collection part extends radially outward to form a dust collection part, and the upper surface of the dust collection part is recessed from the outer periphery to the middle of the through hole.

[0006] Preferably, the dust collection part has a plurality of small holes communicating with the dust suction chamber, and the plurality of small holes are distributed around the through hole.

[0007] Preferably, the dust collection part is provided with a dust separator inside, and the through hole extends from the lower end of the dust separator to the dust collection part.

[0008] Preferably, the diameter of the through hole gradually decreases from bottom to top.

[0009] Preferably, the top of the dust separator does not contact the dust collection section to form the notch.

[0010] Preferably, the dust suction chamber is provided with reinforcing ribs, which surround the dust separator.

[0011] Preferably, a T-shaped tube is connected to the rear end of the main body of the suction pipe.

[0012] Its advantages over existing technologies are:

[0013] In this invention, when the laser marking mechanism marks the bottom of a product, the laser passes through the through hole in the middle of the dust collection part. The dust generated during the marking process is sucked into the through hole, then through the notch on the inner wall of the through hole into the dust collection chamber, and then into the dust collection pipe body through the dust collection chamber, and finally into the dust removal pipe. This prevents dust from accumulating on the surface of the laser marking mechanism after long-term marking work, which would affect the laser's optical path and impact the production and processing of the product.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] like Figures 1-3 As shown, a preferred embodiment of this utility model proposes a laser marking dust extraction tube, which mainly includes a dust extraction tube body 1, which is a circular tube. A dust extraction section 2 is located at the front end of the dust extraction tube, allowing dust to be extracted without affecting the upward passage of the laser beam through the dust extraction section 2. The rear end of the dust extraction tube is connected to a dust extraction mechanism, which draws air outward, creating a negative pressure inside the dust extraction tube body 1 to extract the dust.

[0021] In this embodiment, the rear end of the vacuum cleaner body 1 is connected to a T-shaped tube 3 so as to connect with other vacuum cleaner pipes.

[0022] like Figure 1 , Figure 4 As shown, the suction unit 2 has a suction chamber 21 inside, which is connected to the inner wall of the suction pipe body 1. A dust collection unit 4 is provided at the top of the suction unit 2. The dust collection unit 4 is formed by extending radially outward and is used to collect dust. The upper surface of the dust collection unit 4 is a dust collection surface 401, which is a curved surface that is concave from the outer periphery to the center.

[0023] A dust-separating cylinder 5 is provided inside the dust-collecting section 2. The dust-separating cylinder 5 has a through hole 201 in the center, extending from the lower end of the dust-collecting section 2 to the center of the dust-collecting section 4. The dust-separating cylinder 5 serves as the inner wall of the through hole 201, separating it from the dust-collecting chamber 21. The top of the dust-separating section does not contact the bottom of the dust-collecting section; the two are separated. A ring-shaped notch 501 is formed between them, connecting the through hole 201 and the dust-collecting chamber 21. When a negative pressure is generated inside the dust-collecting chamber 21, dust will enter the dust-collecting chamber 21 through the notch 501.

[0024] In other technical solutions, the top of the dust collector 5 can also be connected to the bottom of the dust collection part 4. Multiple notches 501 need to be provided around the top of the dust collector 5 so that dust can enter the dust collection chamber 21.

[0025] In the suction chamber 21, a reinforcing rib 6 is provided on the periphery of the dust separator 5 to strengthen the connection between the dust separator 5 and the suction unit 2.

[0026] like Figure 3 , Figure 4 As shown, the diameter of the through hole 201 gradually decreases from bottom to top. Therefore, when a negative pressure is generated in the dust collection chamber 21, the air flow rate at the upper end of the through hole 201 is the fastest, which easily draws the dust on the surface of the dust collection part 4 into the dust collection chamber 21 and is then drawn away by the main body of the dust collection pipe 1.

[0027] like Figure 1 , Figure 2 As shown, in this embodiment, eight small holes 402 are provided on the dust collection part 4. The eight small holes 402 are distributed around the through hole 201 in sequence, and the diameter of the small holes 402 is much smaller than the upper diameter of the through hole 201. Each small hole 402 is connected to the dust suction chamber 21.

[0028] Product 7 is generally placed above the dust collection section 4, and the laser marking mechanism 8 is generally placed below the dust collection section 2. The laser emitted by the laser marking mechanism 8 will pass upward through the through hole 201 and mark the bottom of product 7. The dust generated during the marking process will accumulate on the dust collection surface 401 of the dust collection section 4.

[0029] like Figure 4As shown, when the main body of the suction pipe 1 draws air outward, a negative pressure is generated in the suction chamber 21. At this time, dust enters through the through hole 201 and then enters the suction chamber 21 through the notch 501. Since the dust collection surface 401 is curved and the central through hole 201 is concave, the small holes 402 dispersed around the through hole 201 will generate eddies, which will attract the dust on the dust collection surface 401 near the outer periphery (i.e., away from the through hole 201) and draw it into the through hole 201 along the curved surface, thus preventing dust from accumulating on the laser marking mechanism 8.

[0030] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
