Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology, specifically a laser cutting head device for an integrated laser grooving and cutting processing equipment. Background Technology

[0002] Laser cutting machines are typically efficient, precise, and can cut relatively thin layers. They work by focusing a laser beam emitted from a laser source into a high-power-density beam through an optical system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal. Laser cutting uses an invisible beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save materials, smooth cuts, and low processing costs.

[0003] Laser cutting machines easily generate sparks during laser cutting, and when products are subjected to laser cutting, waste residue is easily produced. If not cleaned in time, the waste residue will remain on the product, causing defects or scrap. Conventionally, a nozzle is added to the focusing laser cutting head. However, when the nozzle sprays the product for cleaning, it easily generates sparks, which poses certain safety hazards. At the same time, existing laser cutting machines cannot remove and collect the molten metal slag generated during cutting. However, it is difficult to remove the molten metal slag after it has cooled down. Therefore, there is an urgent need to design a laser cutting head device for integrated laser grooving and cutting processing equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a laser cutting head device for an integrated laser grooving and cutting processing equipment, which solves the problems mentioned above, such as the easy generation of waste slag during laser cutting, which will cause waste slag residue and affect product quality if not cleaned in time, the problem of sparks flying when the nozzle sprays the product for cleaning, which poses certain safety hazards, and the problem that existing laser cutting machines cannot remove and collect the generated metal slag during cutting, and that the metal slag is difficult to remove after cooling.

[0005] To solve the above-mentioned technical problems, this utility model provides a laser cutting head device for an integrated laser grooving and cutting processing equipment, including a sliding mechanism and a cutting head mechanism disposed on the sliding mechanism. The cutting head mechanism includes a housing, a connecting plate, several brushes, and several lifting cylinders. The housing is connected to the sliding mechanism, which drives the housing to move up and down. A fixed plate is connected to the bottom of the housing. Several lifting cylinders are disposed inside the housing, and their fixed ends are respectively fixed to the two side walls of the fixed plate. The bottom of the output end of each lifting cylinder is connected to the top of the connecting plate. A baffle is provided on the connecting plate, and several connecting posts for connecting the fixed baffle are connected to the side wall of the output end of each lifting cylinder. The upper ends of several brushes are respectively connected to the four sides of the connecting plate.

[0006] A focusing laser cutting head is mounted on the fixed plate. The lower part of the focusing laser cutting head passes through the fixed plate and the connecting plate and extends outward, and is located inside several brushes. Several nozzles are mounted on the bottom of the connecting plate. Several first gas delivery pipes for supplying gas to each nozzle are provided inside the connecting plate. One end of the first gas delivery pipe passes through the connecting plate and the housing and is connected to a second gas pipe. The other end passes through the connecting plate and is connected to the nozzle. The nozzles are oriented towards the focusing laser cutting head.

[0007] Furthermore, the number of brushes is four, and the four brushes are respectively connected to the lower perimeter of the connecting plate.

[0008] Furthermore, the vertical cross-section of the fixing plate is U-shaped, and there are two lifting cylinders. The fixed ends of the two lifting cylinders are respectively fixed to the two side walls of the fixing plate, and the bottom of their output ends are connected to the four edges of the connecting plate.

[0009] Furthermore, the sliding mechanism is equipped with a driving mechanism.

[0010] Furthermore, the sliding mechanism includes a fixed guide rail and a sliding sleeve, the sliding sleeve being slidably disposed on the fixed guide rail and fixedly connected to the housing.

[0011] Furthermore, the connecting plate has a through hole in the middle for the focusing laser cutting head to pass through, and there is a gap between the through hole and the connecting plate.

[0012] Furthermore, the number of the first gas delivery pipes, the number of the second gas delivery pipes, and the number of the nozzles are equal, and there are four of each. Each second gas pipe is connected to a solenoid valve, and the inlet end of the second gas pipe is connected to a gas storage system. Each inlet end of the first gas delivery pipe is equipped with a gas pipe connector for docking with the second gas pipe.

[0013] The beneficial effects of this utility model are as follows: Under the driving force of the drive mechanism, the sliding mechanism of this utility model drives the cutting head mechanism to move up and down, so as to adjust the distance between the focusing laser cutting head and the workpiece to meet the cutting and laser requirements. Then, by controlling the brush and connecting plate to move downward through several lifting cylinders, the baffle moves downward at the same time, so that the baffle and brush can always be positioned around the outside of the focusing laser cutting head. This prevents the sparks generated during the grooving process from flying out of the baffle or brush when the nozzle cleans the waste residue on the product. The baffle can effectively block the metal slag and sparks generated during the grooving process, and at the same time, it does not block the direction of airflow. The brush can also be used to gather and collect the metal slag, thereby improving the multifunctionality and safety of the laser cutting equipment.

[0014] The configuration of several first gas delivery pipes within the connecting plate, the second gas delivery pipes connected to the first gas delivery pipes, and the solenoid valves on the second gas delivery pipes allows for individual control of each nozzle. This enables independent air blowing in four directions to the focusing laser cutting head, facilitating the removal of molten metal slag from the product during cutting or laser processing, reducing defective products, and improving the quality of laser cutting and product processing.

[0015] The gap between the through hole of the connecting plate and the focusing laser cutting head is designed to prevent the connecting plate from being unable to move due to interference from the connection between the focusing laser cutting head and the connecting plate when it moves up and down.

[0016] The focusing laser cutting head uses a collimated focusing cutting head, which can provide a larger focusing range to meet the cutting and laser requirements of products of different heights. Attached Figure Description

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following will describe a specific embodiment of this utility model and its appendix. Figure 1-4 This document details a laser cutting head device for an integrated laser grooving and cutting processing equipment. The device includes a sliding mechanism 1 and a cutting head mechanism 2 mounted on the sliding mechanism 1. The cutting head mechanism 2 comprises a housing 21, a connecting plate 22, several brushes 23, and several lifting cylinders 24. The housing 21 is connected to the sliding mechanism 1, which drives the housing 21 to move up and down. A fixing plate 27 is connected to the bottom of the housing 21. Several lifting cylinders 24 are disposed inside the housing 21, and their fixed ends are respectively fixed to the two side walls of the fixing plate 27. The bottom of the output end of each lifting cylinder 24... All are connected to the top of the connecting plate 22. The connecting plate 22 is provided with a baffle 28, and each lifting cylinder 24 has several connecting posts on the output end side wall for connecting and fixing the baffle 28. The upper ends of several brushes 23 are respectively connected to the four sides of the connecting plate 22. The brushes 23 are made of metal, preferably copper. The metal brushes 23 can remove the hot metal slag, so as to avoid the problem of the metal slag adhering to the product after cooling and then being removed, which would cause product defects. There are four brushes 23, and the four brushes 23 are respectively connected to the lower four sides of the outer wall of the connecting plate 22.

[0025] The vertical section of the fixed plate 27 is U-shaped. There are two lifting cylinders 24. The fixed ends of the two lifting cylinders 24 are fixed to the two side walls of the fixed plate 27 respectively, and the bottom of their output ends are connected to the four edges of the connecting plate 22.

[0026] A focusing laser cutting head 25 is mounted on the fixed plate 27. The focusing laser cutting head is a collimated focusing cutting head, which can provide a larger focusing range to meet the cutting and laser requirements of products of different heights. The lower part of the focusing laser cutting head 25 passes through the fixed plate 27 and the connecting plate 22 and extends out, and is located inside several brushes 23. Several nozzles 26 are mounted on the bottom of the connecting plate 22. Several first gas delivery pipes for supplying gas to each nozzle 26 are provided inside the connecting plate 22. One end of the first gas delivery pipe passes through the connecting plate 22 and the housing 21 and is connected to the second gas pipe. The other end passes through the connecting plate 22 and is connected to the nozzle 26. The nozzles 26 are set towards the focusing laser cutting head 25. The number of first gas delivery pipes, the number of second gas delivery pipes and the number of nozzles 26 are equal, and there are four of each. Each second gas pipe is connected to a solenoid valve. The inlet end of the second gas pipe is connected to a gas storage system. Each inlet end of the first gas delivery pipe is equipped with a gas pipe connector 29 for docking with the second gas pipe.

[0027] The configuration of several first gas delivery pipes within the connecting plate 22, the second gas delivery pipes connected to the first gas delivery pipes, and the solenoid valves on the second gas delivery pipes allows for individual control of each nozzle 26. This enables independent air blowing in four directions to the focusing laser cutting head 25, facilitating the removal of molten metal slag from the product during cutting or laser processing, reducing defective products, and improving the quality of laser cutting and product processing.

[0028] The sliding mechanism 1 of this invention, driven by the driving force of the driving mechanism, moves the cutting head mechanism 2 up and down to adjust the distance between the focusing laser cutting head 25 of the cutting head mechanism 2 and the workpiece to meet the cutting and laser requirements. Then, through several lifting cylinders 24, the brush 23 and the connecting plate 22 are controlled to move downward, which in turn drives the baffle 28 to move downward at the same time. This ensures that the baffle 28 and the brush 23 are always positioned around the outside of the focusing laser cutting head 25, so that when the nozzle 26 cleans the waste on the product, the sparks generated during the grooving process will not fly out of the baffle 28 or the brush 23. The baffle 28 can effectively block the molten metal slag and sparks generated during the grooving process, and at the same time, it will not block the direction of airflow. The brush 23 can also be used to gather and collect the molten metal slag, thereby improving the multifunctionality and safety of the laser cutting equipment.

[0029] The sliding mechanism 1 is equipped with a driving mechanism. The sliding mechanism 1 includes a fixed guide rail 11 and a sliding sleeve 12. The sliding sleeve 12 is slidably disposed on the fixed guide rail 11 and is fixedly connected to the housing 21.

[0030] The connecting plate 22 has a through hole in the middle for the focusing laser cutting head 25 to pass through. There is a gap between the through hole and the connecting plate 22. The gap between the through hole and the focusing laser cutting head 25 can prevent the connecting plate 22 from being unable to move due to interference from the connection between the focusing laser cutting head 25 and the connecting plate 22 when it moves up and down.

[0031] The working process of this utility model is as follows:

[0032] When it is necessary to adjust the height of the focusing laser cutting head 25, the drive mechanism controls the sliding sleeve 12 and the housing 21 fixed on the sliding sleeve 12 to move up and down, so as to adjust the position of the sliding sleeve 2 to adjust the height of the focusing laser cutting head 25.

[0033] When the brush 23 is needed, the output ends of the two lifting cylinders 24 push the connecting plate 22 to move away from the fixed plate 27. The connecting plate 22 moves downward along the outside of the focusing laser cutting head 25. The brush 23 and the baffle 28 fixed to the lower perimeter of the connecting plate 22 move downward with the connecting plate 22. The baffle 28 can block the laser emitted by the focusing laser cutting head 25, effectively blocking the molten metal slag and sparks generated during the grooving process, without blocking the direction of airflow. It can also prevent the nozzle 26 from causing sparks and injuries to personnel when cleaning the product. At the same time, the four brushes 23 can collect the molten metal slag on the product to improve the cleanliness and quality of the product, thereby improving the overall versatility and safety of the laser cutting equipment.

[0034] When the brush 23 and baffle 28 are not needed, the output ends of the two lifting cylinders 24 retract to drive the connecting plate 22 to move closer to the fixed plate 27, so as to reset the brush 23 and baffle 28.

[0035] When it is necessary to control the number or state of the nozzles 26, the control unit controls the opening and closing of the solenoid valve on each second gas delivery pipeline to realize the opening or closing of each nozzle 26, thereby improving the versatility of the nozzles of the laser cutting equipment. The number of nozzles 26 that are open can be adjusted according to the amount of molten metal slag to reduce the waste of electrical and gas energy.

[0036] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
