Description

Technical Field

[0001] This utility model relates to the field of air conditioner panel processing, and in particular to an air conditioner panel laser engraving machine. Background Technology

[0002] Air conditioner panels require laser engraving machines to achieve high-precision and durable markings, ensuring clear functionality and aesthetics. Laser engraving machines can also be used to process areas on the panel that require hollowing out.

[0003] Laser engraving machines generate a large amount of smoke and fine, flying particles during processing. This smoke not only affects the transmission efficiency of laser energy but also contaminates and corrodes internal components, shortening the equipment's lifespan. Furthermore, the smoke contains harmful gases that pose a threat to the health of operators. Current solutions mainly involve placing air purifiers near the engraving machine or operating a fresh air system in the workshop. However, the process from the generation of the smoke until it enters the treatment system still causes damage to the surrounding environment and the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a laser engraving machine for air conditioner panels, which solves the problem that the smoke generated during laser processing can damage the internal components of the equipment and pollute the processing environment. Furthermore, the grease and particles in the smoke can also contaminate the laser head lens and affect the focusing efficiency.

[0005] To solve the problems of the existing technology, the technical solution of this utility model is as follows: an air conditioner panel laser engraving machine includes a machine frame and a laser head set in the machine frame. The bottom of the machine frame near the laser head is provided with a connecting pipe for connecting an external receiving and collecting device. A blocking ring is provided at the end of the connecting pipe. Several through holes are evenly opened at the bottom of the blocking ring. A collecting pipe is provided at the bottom of the connecting pipe. Reinforcing ribs are provided on both sides of the surface of the collecting pipe. A clearance groove is opened at the end of the collecting pipe. A resistance baffle is provided on the side of the blocking ring near the connecting pipe.

[0006] Furthermore, the equipment frame is divided into a frame body and a connecting part located on the outside of the frame body. The laser head is located on the surface of the connecting part, and the connecting pipe is located at the bottom of the connecting part and extends to the output end of the laser head, ensuring that the connecting pipe can move with the laser head and always maintain a constant relative position.

[0007] Furthermore, the barrier ring is an annular pipe surrounding the laser head. The connecting pipe extends into the annular pipe and leaves a gap between it and the pipe wall. A resistance baffle is set at the end of the connecting pipe, so that the laser head is blocked by the barrier ring. External air needs to pass through the barrier ring before contacting the laser head, and the internal gas flow is restricted by the connecting pipe.

[0008] Furthermore, the resistance baffle is a plate-shaped structure with perforations symmetrically opened on both sides, and the upper and lower sides of the resistance baffle are connected to the inner wall of the barrier ring, thereby limiting the gas flow rate inside the barrier ring.

[0009] Furthermore, the through holes at the bottom of the barrier ring are inclinedly arranged on the surface of the barrier ring, and several through holes are radially distributed to increase the air intake range of the through holes and ensure that the air intake range of each through hole has an overlapping part.

[0010] Furthermore, the collecting tube is L-shaped overall, with the vertical portion connected to the connecting tube and the horizontal portion extending to the output end of the laser head and aligned vertically.

[0011] Furthermore, the reinforcing ribs on the surface of the collecting tube are provided in the vertical portion and extend to the bend, and the diameter of the reinforcing ribs gradually decreases from the vertical portion to the bend, so that the collecting tube can deform at any time under pressure while maintaining sufficient strength, and recover after deformation.

[0012] Furthermore, the top of the end of the connecting pipe with the clearance groove extends outward to cover the bottom, increasing the coverage area of ​​the connecting pipe.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention uses a barrier ring to absorb smoke near the laser head. Due to the restriction of the connecting pipe and the resistance baffle inside the barrier ring, gas flow is limited. Therefore, when the connecting pipe generates suction, the suction force generated by the collecting pipe is greater than that of the barrier ring. This ensures that the collecting pipe can quickly and effectively absorb the smoke generated at the processing location. At the same time, the smoke diffused in the air will be sucked into the barrier ring when it approaches the laser head, ensuring that the smoke will not come into contact with the laser head and its internal components, causing pollution and damage. Meanwhile, the suction force of the barrier ring is relatively small, so it will not bypass the collecting pipe and directly absorb the smoke, causing the smoke to quickly approach the laser head.

[0015] The outward extension of the collection tube at the end of this invention can cover the processing area. The smoke and particles generated in the processing area are covered and cannot move directly upward, which slows down the drift speed of pollutants and limits their drift direction, while not blocking the normal processing of the laser head emitting laser light.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1-5 As shown, an air conditioner panel laser engraving machine includes a frame 1 and a laser head 2 disposed within the frame 1. A connecting pipe 3 for connecting an external receiving device is disposed at the bottom of the frame 1 near the laser head 2. The frame 1 is divided into a frame body and a connecting part disposed on the outside of the frame body. The laser head 2 is disposed on the surface of the connecting part, and the connecting pipe 3 is disposed at the bottom of the connecting part and extends to the output end of the laser head 2, ensuring that the connecting pipe 3 can move with the laser head 2 and always maintains a constant relative position.

[0024] A blocking ring 4 is provided at the end of the connecting pipe 3. Several through holes 5 are evenly opened at the bottom of the blocking ring 4. The through holes 5 at the bottom of the blocking ring 4 are inclined and radially distributed to increase the air intake range of the through holes 5 and ensure that the air intake range of each through hole 5 has an overlapping part. A collecting pipe 6 is provided at the bottom of the connecting pipe 3. The collecting pipe 6 is L-shaped. The vertical part is connected to the connecting pipe 3, and the horizontal part extends to the output end of the laser head 2 and is vertically aligned. Reinforcing ribs 7 are provided on both sides of the surface of the collecting pipe 6. The reinforcing ribs 7 on the surface of the collecting pipe 6 are set at the vertical part and extend to the bend. The diameter of the reinforcing ribs 7 gradually decreases from the vertical part to the bend, so that the collecting pipe 6 can deform at any time when under pressure while maintaining sufficient strength and recover after deformation. A relief groove 8 is provided at the end of the collecting pipe 6. The top of the end of the connecting pipe 3 with the relief groove 8 extends outward to cover the bottom, increasing the coverage area of ​​the connecting pipe 3.

[0025] A baffle 9 is provided on the side of the barrier ring 4 near the connecting pipe 3. The barrier ring 4 is an annular pipe that surrounds the laser head 2. The connecting pipe 3 extends into the annular pipe and leaves a gap between it and the pipe wall. The baffle 9 is located at the end of the connecting pipe 3, so that the laser head 2 is blocked by the barrier ring 4. External air needs to pass through the barrier ring 4 before contacting the laser head 2. The internal gas flow of the barrier ring 4 is restricted by the connecting pipe 3. The baffle 9 is a plate-shaped structure with perforations symmetrically opened on both sides. The upper and lower sides of the baffle 9 are connected to the inner wall of the barrier ring 4. The gas flow rate inside the barrier ring 4 is restricted by the baffle 9.

[0026] Working principle explanation: First, during processing, the external receiving and collecting device generates suction through the connecting pipe 3. The suction acts on the blocking ring 4 and the collecting pipe 6 through the connecting pipe 3. At this time, the blocking ring 4 is restricted by the resistance baffle 9, so the gas movement resistance is relatively large. However, the collecting pipe 6 is unobstructed, so the suction generated by the collecting pipe 6 is greater than that of the blocking ring 4. When the laser head 2 is processing, the laser comes into contact with the workpiece through the relief groove 8 and generates smoke. At this time, the smoke is quickly sucked into the collecting pipe 6 with greater suction. Some of the drifting gas moves in the air and passes through the blocking ring 4 when it approaches the laser head 2. Under the action of suction, the through holes 5 on the surface of the blocking ring 4 collect these drifting gases. After being sucked in, the gas enters the collecting equipment through the connecting pipe 3 for subsequent harmless treatment. In addition, the splashing particles generated during the processing are blocked by the relief groove 8 at one end of the collecting pipe 6 and will not directly contact the laser head 2.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
