Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and specifically relates to a powder collection device for metal laser marking. Background Technology

[0002] Metal laser marking is a processing method that uses laser technology to scratch the surface of metal. A high-energy-density laser beam is released and focused on the metal surface, which is rapidly melted or even vaporized, thereby forming tiny pits or marks on the metal surface.

[0003] When laser scribing is performed on metal, the molten and vaporized metal on its surface leaves the scribing area and rapidly cools and solidifies in the surrounding environment, forming fine metal powder. When the laser acts on the metal surface, it generates a certain impact force, which may cause some tiny particles on the metal surface to be impacted and detached from the metal body, splashing out in the form of powder.

[0004] In existing technologies, metal powder is generally sucked up by a dust collection device to avoid the metal powder affecting the processing quality. However, the metal powder particles are small and easily accumulate on the filter screen of the dust collection device. With prolonged use, the filter screen will gradually become clogged, which will lead to poor ventilation and affect the working efficiency of the dust collection device.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a powder collection device for metal laser marking, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a powder collection device for metal laser marking, comprising a housing:

[0009] The housing is respectively provided with an exhaust assembly, a collection assembly, a filter assembly, a drive assembly, and a cleaning assembly;

[0010] The exhaust assembly has its exhaust end connected to the interior of the collection assembly, so that the exhaust assembly can extract the air from the interior of the collection assembly for the collection assembly to collect the metal powder in the air.

[0011] The filter assembly is fixedly installed on its outer surface and inside the collection assembly so that the filter assembly can filter the metal powder entering the collection assembly.

[0012] The drive assembly has its output end connected to the internal thread of the cleaning assembly, so that the drive assembly drives the cleaning assembly to clean the metal powder adhering to the surface of the filter assembly.

[0013] Furthermore, the exhaust assembly includes an exhaust fan and a collection pipe. The bottom end of the exhaust fan is fixedly installed inside the housing, and a connecting pipe is fixedly installed at the exhaust end of the exhaust fan. One end of the connecting pipe is connected to the inside of the collection assembly.

[0014] The outer surface of the collecting tube is fixedly installed to the inside of the housing, and one end of the collecting tube is connected to the inside of the collecting assembly.

[0015] Furthermore, the collection assembly includes a support frame, the bottom end of which is fixedly installed inside the housing, a collection box is fixedly installed at the top end of the support frame, the bottom end of the collection box is fixedly installed at one end of the connecting pipe, and one side of the collection box is fixedly installed at one end of the collection pipe.

[0016] The inside of the collection box is fixedly connected to a partition, a guide plate is fixedly connected to one side of the partition, and a collection box is slidably disposed on one side of the partition.

[0017] Furthermore, the filter assembly includes a mounting groove, which is formed at the top of the partition. A filter screen is installed inside the mounting groove, and a protrusion is fixedly connected to one side of the filter screen.

[0018] Furthermore, the drive assembly includes a motor, one side of which is fixedly mounted to one side of the collection box, and a threaded rod is fixedly mounted on the output end of the motor.

[0019] Furthermore, the cleaning assembly includes a sliding rod, both ends of which are fixedly connected to the inner wall of the collection box. An mounting block is slidably disposed on the outer surface of the sliding rod. The interior of the mounting block is threadedly connected to the threaded surface of the threaded rod. A brush is fixedly connected to one side of the mounting block, and one side of the brush is in contact with one side of the filter screen.

[0020] Furthermore, the cleaning assembly also includes a striker, the outer surface of which is slidably disposed with the interior of the mounting block, one end of which is fixedly connected to a connecting plate, one side of which is fixedly connected to a tension spring, one end of which is fixedly connected to one side of the mounting block, and the outer surface of the striker is in contact with the outer surface of the protrusion.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model drives the cleaning component connected to the output end of the drive component to reciprocate, so that it can clean the metal powder attached to one side of the filter component during the movement, and collect it through the collection component to avoid the metal powder from clogging the filter component, thereby ensuring that the exhaust component can normally and stably suck the metal powder into the inside of the collection component.

[0023] 2. This utility model uses a starting motor to drive the threaded rod to rotate, which in turn causes the threaded mounting block connected to the threaded surface to move along the direction of the sliding rod. This causes the fixed brush on one side to clean the metal powder filtered on one side of the filter screen, thus preventing the metal powder from accumulating on one side of the filter screen.

[0024] 3. This utility model moves the mounting block, causing the sliding impact rod inside it to move. Since the outer surface of the impact rod is in contact with the outer surface of the protrusion, and there are multiple sets of protrusions, when the impact rod contacts the protrusion, it can push the impact rod to move, thereby moving the connecting plate fixedly connected at one end, and causing it to stretch the tension spring. When the impact rod passes a set of protrusions, the tension spring applies a pulling force to the connecting plate, causing it to drive the impact rod to impact the filter screen. The vibration helps to remove the metal powder attached to the surface of the filter screen, preventing the metal powder from clogging the filter screen.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0036] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0037] Please see Figures 1-6 As shown, this utility model is a powder collection device for metal laser marking, including a housing 1:

[0038] The housing 1 is respectively provided with an exhaust assembly 2, a collection assembly 3, a filter assembly 4, a drive assembly 5, and a cleaning assembly 6;

[0039] The exhaust assembly 2 has its exhaust end connected to the interior of the collection assembly 3, so that the exhaust assembly 2 can extract the air from the interior of the collection assembly 3 for the collection assembly 3 to collect the metal powder in the air.

[0040] The filter assembly 4 is fixedly installed on its outer surface and inside the collection assembly 3 so that the filter assembly 4 can filter the metal powder entering the collection assembly 3.

[0041] The drive component 5 has its output end connected to the internal thread of the cleaning component 6, so that the drive component 5 drives the cleaning component 6 to clean the metal powder adhering to the surface of the filter component 4.

[0042] In use, by moving the housing 1 to one side of the laser marking stage, so that the air inlet of the exhaust assembly 2 is opposite to the side of the laser marking process, the exhaust assembly 2 is activated to draw outside air into the collection assembly 3. As the air flows, metal powder in the air is drawn into the collection assembly 3 and filtered by the filter assembly 4. When the metal powder adheres to one side of the filter assembly 4 due to the air flow, the drive assembly 5 is activated to drive the cleaning assembly 6, which is threadedly connected to the output end, to reciprocate. During the movement, the cleaning assembly 6 cleans the metal powder adhering to one side of the filter assembly 4 and collects it through the collection assembly 3 for centralized processing.

[0043] This invention uses the start-up drive component 5 to drive the cleaning component 6, which is threadedly connected to the output end, to reciprocate. During the movement, the cleaning component 6 can clean the metal powder attached to one side of the filter component 4 and collect it through the collection component 3 to prevent the metal powder from clogging the filter component 4. This ensures that the exhaust component 2 can normally and stably draw the metal powder into the collection component 3.

[0044] In one embodiment, the exhaust assembly 2 includes an exhaust fan 201 and a collection pipe 202. The bottom end of the exhaust fan 201 is fixedly installed inside the housing 1. A connecting pipe 203 is fixedly installed at the exhaust end of the exhaust fan 201. One end of the connecting pipe 203 is connected to the inside of the collection assembly 3.

[0045] The outer surface of the collection tube 202 is fixedly installed inside the housing 1, and one end of the collection tube 202 is connected to the inside of the collection component 3.

[0046] By activating the exhaust fan 201 and connecting pipe 203, the air inside the collection component 3 is extracted. Since the inside of the collection component 3 is connected to the inside of the collection pipe 202, and one end of the collection pipe 202 corresponds to the side where the laser marking is processed, when the air inside the collection component 3 is extracted, it can work with the collection pipe 202 to draw outside air into the inside of the collection component 3. Thus, with the flow of air, the metal powder generated by the laser marking can be drawn into the inside of the collection component 3.

[0047] In one embodiment, the collection component 3 includes a support frame 301, the bottom end of which is fixedly installed inside the housing 1, a collection box 302 is fixedly installed at the top end of the support frame 301, the bottom end of the collection box 302 is fixedly installed at one end of the connecting pipe 203, and one side of the collection box 302 is fixedly installed at one end of the collection pipe 202.

[0048] A partition 303 is fixedly connected inside the collection box 302. A guide plate 304 is fixedly connected to one side of the partition 303. A collection box 305 is slidably disposed on one side of the partition 303.

[0049] By activating the exhaust fan 201 and connecting pipe 203, air is extracted from the inside of the collection box 302 to create a negative pressure. This allows the exhaust fan, in conjunction with the collection pipe 202, to draw outside air into the collection box 302, causing the metal powder to enter the collection box 302. Under its own gravity, the metal powder falls to one side of the partition 303 and slides along the guide plate 304 fixed to one side of the partition 303 into the collection box 305, facilitating the collection and centralized processing of the metal powder.

[0050] In one embodiment, the filter assembly 4 includes a mounting groove 401, which is located at the top of the partition 303. A filter screen 402 is installed inside the mounting groove 401, and a protrusion 403 is fixedly connected to one side of the filter screen 402.

[0051] When metal powder enters the collection box 302 with the airflow, it first comes into contact with the filter screen 402 to filter the metal powder carried by the airflow. Since the filter screen 402 is installed inside the partition 303 with the mounting groove 401, the filtered metal powder can be blocked on one side of the partition 303 to facilitate the collection of metal powder.

[0052] In one embodiment, the drive assembly 5 includes a motor 501, one side of which is fixedly installed on one side of the collection box 302, and a threaded rod 502 is fixedly installed on the output end of the motor 501.

[0053] The threaded rod 502 installed at the output end is driven by the starting motor 501 to rotate. Since the motor 501 is a forward and reverse motor, it can drive the threaded rod 502 to rotate alternately in the forward and reverse directions.

[0054] In one embodiment, the cleaning component 6 includes a sliding rod 601, both ends of which are fixedly connected to the inner wall of the collection box 302. An mounting block 602 is slidably disposed on the outer surface of the sliding rod 601. The interior of the mounting block 602 is threadedly connected to the threaded surface of the threaded rod 502. A brush 603 is fixedly connected to one side of the mounting block 602, and one side of the brush 603 is in contact with one side of the filter screen 402.

[0055] By starting the motor 501 to drive the threaded rod 502 to rotate, it causes the threaded mounting block 602 to move along the direction of the sliding rod 601, thereby causing the fixed brush 603 on one side to clean the metal powder filtered on one side of the filter screen 402, so as to prevent the metal powder from accumulating on one side of the filter screen 402.

[0056] In one embodiment, the cleaning component 6 further includes a striker 604, the outer surface of which is slidably disposed with the interior of the mounting block 602. One end of the striker 604 is fixedly connected to a connecting plate 605, and one side of the connecting plate 605 is fixedly connected to a tension spring 606. One end of the tension spring 606 is fixedly connected to one side of the mounting block 602, and the outer surface of the striker 604 is in contact with the outer surface of the protrusion 403.

[0057] When the mounting block 602 moves with the rotation of the threaded rod 502, it can drive the sliding impact rod 604 inside it to move. Since the outer surface of the impact rod 604 is in contact with the outer surface of the protrusion 403, and there are multiple sets of protrusions 403, when the impact rod 604 contacts the protrusion 403, it can push the impact rod 604 to move, so that it drives the connecting plate 605 fixedly connected at one end to move, and drives the tension spring 606 to stretch. When the impact rod 604 passes a set of protrusions 403, the tension spring 606 applies a pulling force to the connecting plate 605, so that it drives the impact rod 604 to impact the filter screen 402. The vibration helps to remove the metal powder attached to the surface of the filter screen 402, and avoids the metal powder from clogging the filter screen 402.

[0058] Through the above technical solution, 1. The cleaning component 6 connected to the output end by the start drive component 5 is driven to reciprocate, so that it can clean the metal powder attached to one side of the filter component 4 during the movement, and collect it through the collection component 3, so as to avoid the metal powder from clogging the filter component 4, thereby ensuring that the exhaust component 2 can normally and stably suck the metal powder into the interior of the collection component 3.

[0059] 2. By starting the motor 501, the threaded rod 502 is driven to rotate, so that it drives the threaded mounting block 602 connected to the threaded surface to move along the direction of the sliding rod 601, thereby driving the fixed brush 603 on one side to clean the metal powder filtered on one side of the filter screen 402, so as to avoid the accumulation of metal powder on one side of the filter screen 402.

[0060] 3. The movement of the mounting block 602 causes the sliding impact rod 604 inside it to move. Since the outer surface of the impact rod 604 is in contact with the outer surface of the protrusion 403, and there are multiple sets of protrusions 403, when the impact rod 604 contacts the protrusion 403, it can push the impact rod 604 to move, so that it drives the connecting plate 605 fixedly connected at one end to move, and drives the tension spring 606 to stretch. When the impact rod 604 passes a set of protrusions 403, the tension spring 606 applies a pulling force to the connecting plate 605, so that it drives the impact rod 604 to impact the filter screen 402. The vibration helps to remove the metal powder attached to the surface of the filter screen 402, and avoids the metal powder from clogging the filter screen 402.
