Description

Technical Field

[0001] This utility model relates to the field of parts marking technology, specifically to a parts surface marking device. Background Technology

[0002] Laser marking is a marking method that uses a high-energy-density laser to locally irradiate a workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Laser marking can produce various texts, symbols, and patterns, with character sizes ranging from millimeters to micrometers, which is of particular significance for the anti-counterfeiting of parts.

[0003] CN221582365U discloses a marking device with anti-displacement capability, which includes a body, a placement plate fixedly connected to the upper side of the body, an anti-displacement device to prevent the marking of parts from shifting, a horizontal moving mechanism fixedly connected to the upper side of the body, and a vertical moving mechanism, a telescopic arm, and a laser marking device arranged above the body.

[0004] However, when a laser irradiates the surface of a material, it causes the material to melt and vaporize instantly, generating a large number of smoke particles. The existing technology mentioned above cannot treat the smoke generated during laser marking of parts. If employees are exposed to this smoke for a long time, they may experience a series of respiratory symptoms. In addition to the harm to the respiratory tract, laser marking smoke may also damage the employees' skin. For example, some chemicals in the smoke may cause allergic reactions when they come into contact with the skin. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a marking device for the surface of parts, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a part surface marking device, comprising a body and a fume purifier, wherein the body is provided with a laser marking component and a clamping component for holding the part;

[0007] The smoke purifier is connected to a fan, and the fan is connected to a smoke horn via a flexible hose.

[0008] The machine body is provided with a mounting rod, and an electric telescopic rod is horizontally arranged on the mounting rod. A lifting component is provided on the output end of the electric telescopic rod, and a baffle is provided on the lifting component opposite to the smoking horn. A bidirectional electric guide rail is provided on the baffle. Sliders are provided on both sides of the output end of the bidirectional electric guide rail, and side rods are provided on the sliders. A sealing component is provided between the side rods and the baffle.

[0009] Preferably, the lifting assembly includes a fixed cover connected to the output end of the electric telescopic rod, a screw is connected to the top of the fixed cover, and an elastic device is connected to the bottom of the screw.

[0010] Preferably, the elastic device includes a slide rod mounted on the bottom of the screw via a bearing, the slide rod being slidably connected to a fixed cover, a connecting block being slidably connected to the bottom of the slide rod, and a spring being provided between the connecting block and the slide rod, a connecting rod being provided on the connecting block and connected to a baffle, and a handle being provided on the connecting rod.

[0011] Preferably, the sealing assembly includes a sealing strip, the height of which is the same as the height of the baffle and the side rod, and one side of the sealing strip contacts the baffle, while the other side of the sealing strip is connected to the side rod.

[0012] Preferably, the right side of the side rod is provided with two positioning rods that contact the front and rear sides of the sealing strip respectively.

[0013] Preferably, the baffle has beveled sections at both the front and rear ends on the left side.

[0014] This invention provides a marking device for the surface of parts. Compared with the prior art, it has the following advantages:

[0015] 1. This part surface marking equipment uses a baffle that can be adjusted both horizontally and vertically to contact the top of the part. The baffle is positioned as close as possible to the right end of the laser marking area without affecting the marking process. This brings the distance between the baffle and the fume extractor closer. Combined with adjustable side rods on both sides, the smoke generated during marking is reduced in its dispersion range by the baffle and side rods. This allows the smoke to be drawn closer to the fume extractor on the left, making it easier to remove completely. The smoke is then purified by a fume extractor, protecting the health of the workers.

[0016] 2. The marking equipment for the part surface is equipped with a lifting assembly including a screw and a spring, which allows for easy adjustment of the height and facilitates the upward movement of the baffle to remove the part; the sealing assembly prevents smoke from escaping from the gap between the side rod and the baffle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-4 This utility model provides the following two technical solutions:

[0024] First embodiment: A part surface marking device, including a body 1 and a fume purifier 2, wherein a laser marking component 3 and a clamping component 4 for holding the part are provided on the body 1;

[0025] The smoke purifier 2 is connected to a suction fan, and the suction fan is connected to a smoke horn 5 via a hose. The smoke purifier 2 is equipped with a spark filter, a dust filter, and an activated carbon filter to remove dust and odor from the smoke. When in use, the smoke horn 5 is moved via the hose to be as close as possible to the left side of the laser marking area on the part without affecting the marking, so as to absorb the smoke generated during the marking process.

[0026] The machine body 1 is equipped with a mounting rod 9, and an electric telescopic rod 8 powered by existing technology is horizontally mounted on the mounting rod 9. A lifting component is mounted on the output end of the electric telescopic rod 8, and a baffle 6 is mounted on the lifting component opposite to the smoke horn 5. The height and horizontal position of the baffle 6 are adjustable. By having the baffle 6 contact the top of the part and positioning it as close as possible to the right end of the laser marking area without affecting the marking, the distance between the baffle 6 and the smoke horn 5 can be reduced, thus preventing smoke from escaping to the right. A bidirectional electric guide rail 10 powered by existing technology is mounted on the baffle 6. Slider 11 is mounted on both sides of the output end of the bidirectional electric guide rail 10, and side rods 12 are mounted on the sliders 11. The two side rods 12 can be moved in opposite directions to guide the smoke blocked by the baffle 6, reducing its escaping range. A sealing component is mounted between the side rods 12 and the baffle 6.

[0027] The lifting assembly includes a fixed cover 13 connected to the output end of the electric telescopic rod 8, which can drive the fixed cover 13 to move laterally. A screw 14 is connected to the top of the fixed cover 13, and an elastic device is connected to the bottom of the screw 14. The screw 14 drives the elastic device to lift and lower.

[0028] The elastic device includes a slide rod 15 mounted on the bottom of the screw 14 via a bearing. The slide rod 15 is slidably connected to the fixed cover 13. A connecting block 16 is slidably connected to the bottom of the slide rod 15, and a spring 17 is provided between the connecting block 16 and the slide rod 15. A connecting rod 7 connected to the baffle 6 is provided on the connecting block 16, and a handle 18 is provided on the connecting rod 7. By rotating the screw 14, the baffle 6 contacts the top of the part. After marking is completed, the handle 18 is moved upward, causing the connecting block 16 to slide inside the slide rod 15, thereby compressing the spring 17. This eliminates the need to rotate the screw 14, making it convenient to remove the part.

[0029] The sealing assembly includes a sealing strip 19, the height of which is the same as that of the baffle 6 and the side rod 12. One side of the sealing strip 19 contacts the baffle 6, and the other side of the sealing strip 19 is connected to the side rod 12, which can prevent smoke from escaping between the side rod 12 and the baffle 6.

[0030] The right side of the side rod 12 is provided with two positioning rods 20 that contact the front and rear sides of the sealing strip 19 respectively, to prevent misalignment during replacement.

[0031] The second implementation method differs from the first implementation method in that: both the front and rear ends of the left side of the baffle 6 are provided with inclined surfaces 21, so that after the sealing strip 19 is replaced, it can be gradually squeezed by the inclined surfaces 21 and eventually adhere to the baffle 6.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] In use, adjust the position of the baffle 6 so that its bottom contacts the part and is as close as possible to the right end of the laser marking area on the part. Then, move the smoke horn 5 as close as possible to the left end of the laser marking area on the part. The smoke generated during laser marking can be blocked by the baffle 6, and the side rods 12 on the front and rear sides can further block it. This reduces the range of smoke generated during marking by blocking it with the baffle 6 and the side rods 12, making the smoke closer to the smoke horn 5 on the left side. This allows the smoke to be completely sucked away by the smoke horn 5 and then purified by the smoke purifier 2. Finally, the part is released by the clamp assembly 4, and then the handle 18 is moved up to compress the spring 17, so that the baffle 6 no longer squeezes the part, and the part can be removed.
