Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and more particularly to a laser processing head with an integrated homogenizer. Background Technology

[0002] Laser processing equipment is widely used in precision machining processes such as cutting, marking, and welding, and the laser processing head is its core working component.

[0003] In existing technologies, conventional laser processing heads have a single structural function and most do not integrate a dedicated dust collection and fume extraction mechanism. During laser processing, the material is vaporized and melted at high temperatures, generating a large amount of pollutants such as metal dust and volatile harmful fumes. Relying solely on external fixed dust collection equipment in the workshop is difficult to adapt to the dynamic working conditions of the processing head. External dust collection equipment has a fixed dust collection range and cannot move synchronously with the processing point, resulting in blind spots and low dust collection coverage. A large amount of fine dust can easily diffuse and escape. Such dust not only adheres to the surface of the laser processing head lens, contaminating optical components and reducing laser transmission accuracy and processing quality, but also endangers the health of operators and pollutes the working environment. At the same time, the adsorbed dust impurities are difficult and inefficient to clean and maintain later.

[0004] In summary, existing laser processing heads suffer from incomplete dust adsorption and poor dust removal and cleaning convenience, and urgently need optimization and improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a laser processing head with an integrated homogenizer to solve the technical problems of existing laser processing heads lacking an integrated dedicated dust collection mechanism, external dust removal equipment being unable to follow the dynamic operation of the processing point, resulting in blind spots in dust collection, low dust collection coverage, and easy diffusion and escape of fine dust. This invention achieves synchronous and full-coverage dust collection at the laser processing point, completely eliminating dust collection dead zones and effectively preventing the spread of dust during processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser processing head with an integrated homogenizer includes a homogenizing laser processing head, wherein an air inlet filter mechanism is provided on the outer side wall of the homogenizing laser processing head;

[0008] A dust collection mechanism is provided on the outside of the uniform laser processing head and above the air intake filter mechanism.

[0009] A rotary drive mechanism is provided on one side of the uniform laser processing head;

[0010] The air intake filtration mechanism includes a collection plate, which is a circular ring structure with an open upper surface and a hollow interior. The collection plate is sleeved on the outside of the uniform laser processing head. The lower surface of the collection plate, located outside the output end of the uniform laser processing head, is connected to multiple air intake nozzles via a rotating shaft. A filter screen is provided on the inner side of the collection plate, and a toothed ring is fixed on the outer side of the collection plate.

[0011] Furthermore, an abutment is fixed to the outer wall of the uniform laser processing head and below the collection plate, and an upper abutment spring is fixed to the upper surface of the abutment plate, with the top end of the upper abutment spring abutting against the bottom of the collection plate.

[0012] Furthermore, a plurality of support columns are fixed on the inner lower surface of the collection tray, and the tops of the plurality of support columns abut against the lower surface of the filter screen.

[0013] Furthermore, a plurality of pull rings are fixed to the lower surface of the collection tray, and a sponge pad is fixed to the inner side of the pull rings.

[0014] Furthermore, the dust collection mechanism includes a mounting base, one side of which is fixedly connected to the outer wall of the uniform light laser processing head, and a dust pump is fixedly mounted on the other side of the mounting base. The bottom end of the input end of the dust pump is fixedly connected to an air suction pipe, and the bottom end of the air suction pipe is fixedly connected to a sealing ring. The inner side of the sealing ring is fixedly connected to the outer side of the uniform light laser processing head, and the bottom of the sealing ring is in contact with the top of the collection tray.

[0015] Furthermore, two guide seats are fixed on the upper surface of the sealing ring, and an L-shaped striking rod is slidably installed on the inner side of the guide seat. The bottom end of the L-shaped striking rod is integrally formed with a tooth, which meshes with the toothed ring. A return spring is provided between the L-shaped striking rod and the guide seat. A striking plate is fixed on the upper surface of the sealing ring at the opposite ends of the two L-shaped striking rods.

[0016] Furthermore, the rotary drive mechanism includes a mounting plate, one side of which is fixedly connected to the outer wall of the uniform laser processing head. A motor is fixed to the lower surface of the mounting plate, and a second gear is fixed to the bottom end of the output shaft of the motor. The second gear meshes with the first gear ring.

[0017] Furthermore, the lower surface of the sealing ring is integrally formed with multiple limiting blocks, and the upper surface of the filter screen is provided with limiting holes that are adapted to the multiple limiting blocks, and the multiple limiting blocks are inserted into the inner side of the limiting holes.

[0018] Furthermore, a gear one is fixed to the top of the outer wall of the air inlet, and a gear ring two is rotatably mounted on the lower surface of the collection plate and outside the plurality of gears one via a rotating shaft. The gear one meshes with the inner wall of the gear ring two.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention overcomes the drawback of traditional external fixed dust removal equipment that cannot follow the processing operation. By setting a rotatable dust collection and air intake structure, it can achieve 360-degree dust adsorption around the laser processing point without dead angles, greatly expand the dust collection coverage area, and completely eliminate dust collection blind spots.

[0021] 2. It can collect dust synchronously with the laser processing head during dynamic operation, effectively preventing the diffusion and escape of metal dust and volatile harmful fumes. This not only optimizes the workshop working environment and eliminates the harm to the health of operators caused by harmful fumes, but also prevents dust from floating and adhering to the surface of laser processing optical devices, effectively ensuring the laser transmission accuracy and greatly improving the quality of finished products from precision processing such as laser cutting, marking, and welding.

[0022] 3. This invention integrates a self-cleaning filter structure. Relying on the rotational power of the rotating dust collection structure, it can drive the striking structure to continuously reciprocate, periodically vibrating and striking the dust collection structure. This can promptly shake off the dust and impurities adsorbed on the filter surface, effectively preventing filter pore blockage, continuously stabilizing the dust collection and filtration performance of the equipment, ensuring that the dust removal efficiency does not decrease during long-term operation, eliminating the need for frequent manual shutdowns for disassembly and cleaning, greatly reducing the workload and difficulty of equipment cleaning and maintenance, and improving the continuous operation capability and ease of operation and maintenance of the equipment.

[0023] 4. The present invention features an elastic top-tight sealing structure, which ensures that the dust collection structure and the dust suction structure always remain in close contact, effectively improving the overall sealing performance of the equipment, preventing dust leakage from structural joints, further guaranteeing the dust collection effect, and ensuring that the collection tray can be pulled down and opened for easy disassembly and replacement of the filter screen, as well as cleaning of dust and impurities inside the collection tray.

[0024] 5. In this invention, multiple air inlets are driven by gear one and gear ring two, so that by rotating a single air inlet, multiple air inlets can be rotated to adjust the bottom suction direction, thereby adjusting the dust collection range as needed. Attached Figure Description

[0034] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example

[0036] like Figure 1 and Figure 2 As shown, a laser processing head with an integrated homogenizer is provided, including a homogenizing laser processing head 1. A backing plate 5 is fixed on the outer wall of the homogenizing laser processing head 1 and below the collecting plate 201. An upper abutment spring 6 is fixed on the upper surface of the backing plate 5, and the top end of the upper abutment spring 6 abuts against the bottom of the collecting plate 201.

[0037] In use, the abutment plate 5 provides a fixed support base for the upper abutment spring 6. The upper abutment spring 6 always applies an upward elastic pushing force to the collection plate 201, so that the top of the collection plate 201 is always tightly attached to the bottom of the sealing ring 304, ensuring the sealing of the connection between the two and effectively preventing smoke and dust from escaping and spreading from the connection gap. The collection plate 201 can also be manually slid down to squeeze the upper abutment spring 6 to retract and move away from the sealing ring 304, so that the collection plate 201 can be opened for easy cleaning.

[0038] like Figure 3 As shown, an air intake filter mechanism 2 is provided on the outer wall of the uniform laser processing head 1. The air intake filter mechanism 2 includes a collection plate 201, which is a circular ring structure with an open upper surface and a hollow interior. The collection plate 201 is sleeved on the outer side of the uniform laser processing head 1. Multiple air intake nozzles 202 are rotatably connected to the lower surface of the collection plate 201 and located outside the output end of the uniform laser processing head 1 via a rotating shaft. A filter screen 203 is provided on the inner side of the collection plate 201. A toothed ring 204 is fixed on the outer side of the collection plate 201. Multiple support columns 205 are fixed on the lower inner surface of the collection plate 201, and the tops of the multiple support columns 205 are in contact with the lower surface of the filter screen 203. Multiple pull rings 206 are fixed on the lower surface of the collection plate 201. A sponge pad 207 is fixed to the inner side of the pull ring 206; a gear 208 is fixed to the top of the outer wall of the air inlet 202; a gear ring 209 is mounted on the lower surface of the collection tray 201 and outside the multiple gears 208 via a rotating shaft; the outer wall of the gear 208 meshes with the inner wall of the gear ring 209; during laser processing, metal dust and harmful fumes generated at the processing point are sucked into the collection tray 201 through the multiple air inlets 202, achieving preliminary collection of dust throughout the entire area; during this process, the support column 205 provides full support for the filter screen 203; the filter screen 203 can intercept and filter the sucked dust impurities, preventing fine dust from entering the dust collection pipe and avoiding pipe blockage and internal equipment pollution.

[0039] When the filter screen 203 needs to be cleaned or replaced, the operator can hold the pull ring 206 with the sponge pad 207 and pull the collection tray 201 downwards. Overcoming the elasticity of the upper spring 6, the collection tray 201 can be moved down and removed. The sponge pad 207 can improve the grip comfort, prevent slipping and bumping, and facilitate the cleaning and replacement of the filter screen, reducing the difficulty of equipment maintenance.

[0040] Multiple air inlets 202 are driven by the meshing of gear 1 208 and gear ring 2 209, so that by rotating a single air inlet 202, multiple air inlets 202 can be rotated, thereby adjusting the bottom suction direction and adjusting the dust collection range as needed.

[0041] like Figure 4As shown, a dust collection mechanism 3 is provided on the outer side of the uniform laser processing head 1 and above the air intake filter mechanism 2. The dust collection mechanism 3 includes a mounting base 301. The left side of the mounting base 301 is fixedly connected to the right side of the outer wall of the uniform laser processing head 1. A dust collection pump 302 is fixedly fixed on the right side of the mounting base 301. The bottom end of the input end of the dust collection pump 302 is fixedly connected to a suction pipe 303. The bottom end of the suction pipe 303 is located on the outer side of the uniform laser processing head 1 and is fixedly connected to a sealing ring 304. The inner side of the sealing ring 304 is fixedly connected to the outer side of the uniform laser processing head 1, and the bottom of the sealing ring 304 is in contact with the top of the collection tray 201. Two guide seats 305 are fixed on the upper surface of the sealing ring 304. An L-shaped striking rod 306 is slidably installed on the inner side of the guide seat 305. The bottom end of the L-shaped striking rod 306 is integrally formed with a tooth 307. The tooth 307 is engaged with the toothed ring 204. A return spring 308 is provided between the L-shaped striking rod 306 and the guide seat 305. A receiving plate 309 is fixed on the upper surface of the sealing ring 304 and at the opposite ends of the two L-shaped striking rods 306. The receiving plate 309 is in contact with the opposite side of the L-shaped striking rod 306.

[0042] The lower surface of the sealing ring 304 is integrally formed with multiple limiting blocks 310, and the upper surface of the filter screen 203 is provided with limiting holes that are adapted to the multiple limiting blocks 310. The multiple limiting blocks 310 are inserted into the inner side of the limiting holes.

[0043] During operation, the mounting base 301 provides fixed support for the dust pump 302. After the dust pump 302 is started, it generates negative pressure suction through the suction pipe 303. Combined with the sealing ring 304 and the sealing fit structure of the collection tray 201, a negative pressure cavity is formed inside the collection tray 201, continuously drawing in the dust generated by laser processing from the air inlet 202 and transporting it to the dust removal equipment. When the collection tray 201 rotates, the outer toothed ring 204 rotates synchronously. Through the meshing transmission of the tooth head 307, it drives the L-shaped striking rod 306 to slide back and forth along the guide seat 305, causing the L-shaped striking rod 306 to periodically strike the striking plate 309. At the same time, the return spring 308 achieves rapid reset and reciprocating striking. The resulting vibration can be transmitted to the collection tray 201 and the filter screen 203, shaking off the dust and impurities attached to the surface of the filter screen 203, effectively preventing the filter screen pores from clogging, continuously ensuring filtration and dust collection efficiency, and eliminating the need for frequent manual cleaning.

[0044] The filter screen 203 is positioned by the limiting block 310 and the limiting hole, so that when the collection plate 201 below rotates, the filter screen 203 will not rotate with it. At this time, the multiple air inlets 202 rotate with the collection plate 201. When the air intake position is adjusted, the air outlet position relative to the filter screen 203 will also change, so that the air with dust and debris can be evenly distributed on the filter screen 203, avoiding the problem of incomplete filtration caused by partial filtration of the filter screen 203.

[0045] like Figure 5 As shown, a rotary drive mechanism 4 is provided on the left side of the uniform laser processing head 1; the rotary drive mechanism 4 includes a mounting plate 401, the right side of the mounting plate 401 is fixedly connected to the left side of the outer side wall of the uniform laser processing head 1, a motor 402 is fixed on the lower surface of the mounting plate 401, a gear 403 is fixed on the output shaft of the motor 402, and the outer side wall of the gear 403 meshes with the outer side wall of the gear ring 204.

[0046] During equipment operation, the mounting plate 401 provides stable fixed support for the motor 402. After the motor 402 is started, the output shaft of the motor 402 drives the gear 403 to rotate continuously. Through the meshing transmission between the gear 403 and the gear ring 204, the collection plate 201 is driven to rotate uniformly around the uniform laser processing head 1. During the rotation of the collection plate 201, multiple air inlets 202 follow the circumferential rotation, which can achieve 360° dust adsorption around the laser processing point without dead angles, expand the dust collection range, completely eliminate the dust collection blind spots of traditional fixed dust removal structures, and at the same time provide continuous power for the reciprocating striking action of the L-shaped striking rod 306, ensuring the continuous operation of the filter's self-cleaning function.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
