Description

Technical Field

[0001] This utility model relates to the technical field of marking and anti-counterfeiting devices, specifically a laser marking and anti-counterfeiting device for composite frame profiles. Background Technology

[0002] In the production and distribution of composite frame profiles, laser marking is a key means of product traceability and preventing counterfeiting. Its clarity, positional accuracy, and the uniqueness of the anti-counterfeiting pattern are directly related to the market credibility of the product and the protection of corporate rights.

[0003] The anti-counterfeiting effect of traditional marking equipment is often limited by multiple factors: if dust and debris attached to the surface of the profile are not completely removed, pattern breaks or blurred edges are likely to occur during laser marking, resulting in a decrease in the recognizability of the anti-counterfeiting mark; if there is a lack of stable limiting during the profile transportation process, even a slight deviation will cause the mark position to deviate from the preset area, and the marking of products in the same batch will be significantly misaligned, affecting the brand image; the more prominent problem is that simple laser engraved patterns are easily imitated by high-precision equipment, rendering the anti-counterfeiting function ineffective and leaving an opportunity for unscrupulous merchants.

[0004] To address these issues, the industry has attempted to add manual dust removal steps, but these methods are inefficient and cannot prevent secondary pollution. Some equipment improves positioning stability by strengthening the clamping structure, but due to poor adaptability, it requires frequent adjustments when dealing with profiles of different specifications, which in turn prolongs the production cycle. As for so-called "advanced anti-counterfeiting" solutions, the complex marking process often leads to poor marking consistency, making it difficult to play a real anti-counterfeiting role in practical applications.

The telescopic ends of the two first cylinders are fixedly connected to fixing plates, which are used to fix the frame.

[0012] Preferably, a second cylinder is fixedly installed on both the left and right sides of the protective box. The second cylinder is located behind the two first cylinders, and the telescopic ends of the two second cylinders slide through into the interior of the protective box.

[0021] Please see Figure 1-4This utility model provides a new technical solution: a composite frame profile laser marking anti-counterfeiting device, including a mounting base plate 1, a protective box 4 fixedly connected to the middle position of the upper surface of the mounting base plate 1, and a first rectangular groove 13 communicating with the interior of the protective box 4 on both the front and rear surfaces. The protective box 4 is internally fixedly connected to a partition 18, on which a second rectangular groove 17 is provided. The second rectangular groove 17 and the two first rectangular grooves 13 are arranged in a front-to-back correspondence. A dust removal component is provided on the protective box 4. The dust removal component includes an air pump 10, which is fixedly installed on the rear side of the upper surface of the protective box 4. An air supply pipe 9 is fixedly connected to the air outlet of the air pump 10, and the end of the air supply pipe 9 away from the air pump 10 passes through the interior of the protective box 4.

[0022] Furthermore, one end of the gas supply pipe 9 located inside the protective box 4 is fixedly connected to a rectangular gas outlet box 15 that communicates with the inside of the protective box 4. The rectangular gas outlet box 15 is inclined forward and is fixedly connected to the inner wall of the protective box 4.

[0023] Furthermore, a dust collection assembly 12 is fixedly installed on the front side of the upper surface of the protective box 4, and a dust collection pipe 11 is fixedly connected to the dust collection port of the dust collection assembly 12.

[0024] Furthermore, the end of the suction pipe 11 away from the suction component 12 extends into the interior of the protective box 4, and the end of the suction pipe 11 located inside the protective box 4 is fixedly connected to a rectangular suction box 16 that communicates with the interior of the protective box 4. The rectangular suction box 16 is set at a backward tilt.

[0025] Furthermore, the rectangular dust collection box 16 is fixedly connected to the partition 18, which divides the interior of the protective box 4 into a dust removal area and a marking area. Both the rectangular dust collection box 16 and the rectangular air outlet box 15 are located in the dust removal area.

[0026] Furthermore, first cylinders 3 are fixedly installed on both the left and right sides of the protective box 4, and the telescopic ends of the two first cylinders 3 slide through into the interior of the protective box 4. Among them, the telescopic ends of the two first cylinders 3 are fixedly connected to the fixing plates 19, and the two fixing plates 19 are used to fix the frame.

[0027] Furthermore, a second cylinder 5 is fixedly installed on both the left and right sides of the protective box 4. The second cylinder 5 is located behind the two first cylinders 3, and the telescopic ends of the two second cylinders 5 slide through into the interior of the protective box 4.

[0028] Furthermore, concave plates 8 are fixedly connected to the telescopic ends of the two second cylinders 5. Both concave plates 8 are located in the dust removal area, and the rear ends of both concave plates 8 extend out of the interior of the protective box 4 through the first rectangular groove 13 located on the rear side.

[0029] Furthermore, a conveying mechanism 2 is provided inside the second rectangular groove 17. The front and rear ends of the conveying mechanism 2 extend out to the inner walls of the corresponding first rectangular groove 13. The conveying mechanism 2 is fixedly connected to the mounting base plate 1.

[0030] Furthermore, L-shaped fixing plates 6 are fixedly connected to both the left and right sides of the conveying mechanism 2, and guide rods 7 are fixedly connected to the opposing surfaces of the two concave plates 8. The opposing surfaces of the two guide rods 7 slide through the outer surfaces of the corresponding L-shaped fixing plates 6. Among them, multiple connecting rods 20 are rotatably connected to the concave parts of the two concave plates 8, and auxiliary wheels 14 are fixedly sleeved on the outer walls of the multiple connecting rods 20. A marking mechanism is set inside the protective box 4, and the marking mechanism is located in the marking area.

[0031] Furthermore, when using the laser marking anti-counterfeiting device for composite frame profiles, the composite frame profile is first placed on the conveying mechanism 2, and the conveying mechanism 2 runs from back to front; Subsequently, based on the specific width of the composite frame profile, two second cylinders 5 are activated, and the telescopic ends of the two second cylinders 5 push the two concave plates 8 to move to the opposite position. When the telescopic ends of the two second cylinders 5 push the two concave plates 8 to move to a relative position, the multiple auxiliary wheels 14 at the concave part of the concave plate 8 will gradually contact the left and right sides of the composite frame profile. Since the opposing surfaces of the two concave plates 8 are slidably connected to the L-shaped fixed plate 6 through the guide rod 7, the guide rod 7 provides stable guidance for the movement of the concave plates 8, avoids deviation, and ensures that the two concave plates 8 can accurately fit the sides of the profile. The auxiliary wheels 14 limit the profile and prevent the profile from shifting left and right due to vibration during the conveying process, ensuring that it moves stably along the central axis of the conveying mechanism 2. The conveying mechanism 2 (running from back to front) drives the composite frame profile to continue moving forward and enter the dust removal area inside the protective box 4. At this time, the air pump 10 is started, and the compressed air generated by the air pump 10 is delivered to the rectangular air outlet box 15 through the air supply pipe 9. Since the rectangular air outlet box 15 is set to be tilted forward, the airflow will flow forward along the surface of the profile, effectively blowing away dust, debris and other impurities on the surface of the profile, providing a clean surface for subsequent marking. Simultaneously, the dust collection component 12 is activated, and the dust collection component 12 generates negative pressure in the rectangular dust collection box 16 through the dust collection pipe 11. The rectangular dust collection box 16 is tilted backward, opposite to the tilt direction of the rectangular air outlet box 15, forming convection, which can quickly suck in the dust blown by the airflow and collect and process it through the dust collection component 12, preventing the dust from being dispersed in the dust removal area and re-attaching to the profile, ensuring a thorough dust removal effect. The composite frame profile after dust removal enters the marking area through the second rectangular groove 17 on the partition 18; according to the width of the profile, the two first cylinders 3 are activated, and the telescopic ends of the two first cylinders 3 push the fixed plate 19 to move relative to each other until the opposing surfaces of the two fixed plates 19 firmly clamp the profile, preventing the profile from shifting due to laser impact during the marking process and ensuring accurate marking position. The marking mechanism inside the protective box 4 (located in the marking area) is activated to perform laser marking on the surface of the fixed profile to form anti-counterfeiting marks. During the marking process, the conveying mechanism 2 is suspended to ensure that the profile is stationary during marking, thereby improving the clarity and consistency of the marking. After the marking is completed, the telescopic ends of the two first cylinders 3 drive the fixed plate 19 to reset and release the clamping of the profile; the conveying mechanism 2 resumes operation and sends the marked profile out of the protective box 4 through the first rectangular groove 13 on the front side, completing the entire laser marking anti-counterfeiting process. Among them, through the limiting guidance of the concave plate 8 and the auxiliary wheel 14, the coordinated dust removal of the rectangular air outlet box 15 and the rectangular dust collection box 16, the stable clamping of the first cylinder 3, and the precise marking of the marking mechanism, the components work together to achieve efficient, clean and precise marking of the composite frame profile, thus meeting the anti-counterfeiting requirements.
