Description

Technical Field

[0001] The utility model relates to the technical field of marking machines, in particular to a self-cleaning mechanism of a marking machine. Background Art

[0002] Marking machines use a laser generator to generate a high-energy continuous laser beam. The focused laser acts on the substrate, causing the surface material to instantly melt or even vaporize. By controlling the path of the laser on the material surface, the required graphic mark is formed. Currently, general marking machines do not have an automatic cleaning function. Part of the burned material turns into dust or vaporizes and floats in the air. Many operators ignore this type of dust because they do not understand the hazards involved. Long-term operation of the marking machine may cause physical damage.

[0003] According to the patent website's description of an easy-to-clean laser marking machine (authorization publication number: CN214641059U), "An isolation net is fixed to the bottom of the marking operation tank, a funnel is connected below the isolation net, a collection pipe is connected below the funnel, a collection box is connected below the collection pipe, and an opening and closing door is provided on the outside of the collection box."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of this utility model, since an isolation net is fixed at the bottom of the marking operation tank, a funnel is connected below the isolation net, a collection pipe is connected below the funnel, a collection box is connected below the collection pipe, and an opening and closing door is provided on the outside of the collection box, according to the specification and drawings of the utility model, this utility model cannot control dust at the position where the laser contacts the part. In actual production and manufacturing, the dust powder generated by the marking machine does not fall directly into the funnel below the isolation net, but is mixed in the air and floats away with the airflow or is inhaled into the lungs of the operator. Therefore, it is necessary to improve a self-cleaning mechanism of the marking machine to solve the above problem. Utility Model Content

[0006] In order to overcome the problem in actual production and manufacturing that the dust and powder generated by the marking machine does not fall directly into the funnel under the isolation net, but is mixed in the air and floats away with the air flow or is inhaled into the lungs of the operator.

[0007] The technical solution of the utility model is: a self-cleaning mechanism of a marking machine, comprising a marking machine, an isolation component arranged on the marking machine, a dust collection component arranged inside the marking machine and a perforated plate located between the isolation component and the dust collection component, the isolation component comprising an isolation box, an operating port being provided on the side of the isolation box, and a soft curtain component being installed on the upper side of the operating port.

[0008] Preferably, the isolation component on the marking machine can effectively isolate the dust generated by the marking machine during the marking operation, and the dust suction component inside the marking machine can suck away the dust in the isolation component. At the same time, the isolation component includes an isolation box, and an operation port is opened on the side of the isolation box for the user to place and take the parts to be marked. In order to prevent dust from overflowing from the operation port, a soft curtain component is installed on the upper side of the operation port, and the soft curtain component effectively suppresses dust overflow.

[0009] Preferably, the soft curtain assembly includes a support plate and a hanging curtain, and a mounting groove is provided on the lower side of the support plate. When the hanging curtain is inserted into the mounting groove, a long axis can pass through the hole one of the hanging curtain from the side of the mounting groove. The specific soft curtain assembly includes a support plate, a hanging curtain, and a long axis. By passing the long axis through the hole one of the hanging curtain from the side of the mounting groove, the hanging curtain can be effectively prevented from falling from the mounting groove. Thanks to the long axis, the hanging curtain can rotate around the long axis to a certain extent.

[0010] Preferably, when the soft curtain assembly is installed, the hanging curtain can completely cover the operation port. The hanging curtain needs to completely cover the operation port, which can effectively prevent dust from overflowing from the bottom side of the operation port.

[0011] Preferably, the marking machine includes a laser emission head, and the laser emission head is coaxially provided with a connecting pipe 1 facing the laser emission direction, and a flange 1 is provided at one end of the connecting pipe 1. The connecting pipe 1 is fixed to the marking machine through the flange 1, and a thread 1 is provided on the outer ring of the connecting pipe 1. The top of the isolation box is provided with a connecting port, and a connecting pipe 2 can be inserted into the connecting port. The inner wall of the connecting pipe 2 is provided with a thread 2 that can match the thread 1. When the connecting pipe 1 is connected to the connecting pipe 2, the flange 2 at the bottom of the connecting pipe 2 can fit the inner wall of the isolation box. In order to facilitate the installation and disassembly of the isolation component, the connecting pipe 1 and the connecting pipe 2 are connected to each other. When the isolation component is not needed, the connecting pipe 2 is rotated and twisted from one end of the connecting pipe to complete the disconnection of the isolation component from the marking machine. At the same time, the connection between the connecting pipe 1 and the connecting pipe 2 can effectively prevent dust from overflowing from the laser emission head.

[0012] Preferably, the orifice plate includes hole two, which is a threaded hole. The threaded hole structure of hole two is beneficial for fixing the parts that need to be marked. At the same time, hole two can also serve as a dust channel, allowing the dust collection component to smoothly absorb the dust in the isolation component.

[0013] Preferably, the dust collection assembly below the orifice plate includes a dust collection tube and a vacuum cleaner. One end of the dust collection tube is connected to a bell mouth, which can fit on the bottom of the orifice plate and completely cover the hole 2 on the orifice plate. The reason why the bell mouth can completely cover the orifice plate is to prevent dust from falling out of the uncovered hole 2.

[0014] Preferably, the isolation box is made of brown transparent acrylic plates. The laser emission head can emit high-energy lasers, and the brown transparent acrylic plates can protect human eyes.

[0015] Beneficial effects of the utility model:

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figure 1-Figure 5The present utility model provides an embodiment: a self-cleaning mechanism for a marking machine, comprising a marking machine 1, an isolation assembly 2 provided on the marking machine 1, a dust collection assembly 3 provided inside the marking machine 1, and a perforated plate 11 located between the isolation assembly 2 and the dust collection assembly 3, wherein the isolation assembly 2 comprises an isolation box 21, an operation port 211 is provided on the side of the isolation box 21, and a soft curtain assembly 4 is installed on the upper side of the operation port 211. The isolation assembly 2 on the marking machine 1 can effectively isolate the dust generated by the marking machine 1 during the marking operation, while the dust collection assembly 3 inside the marking machine 1 can suck away the dust inside the isolation assembly 2. The isolation assembly 2 comprises an isolation box 21, an operation port 211 is provided on the side of the isolation box 21 for users to place and take parts to be marked, and in order to prevent dust from overflowing from the operation port 211, a soft curtain assembly 4 is installed on the upper side of the operation port 211, and the soft curtain assembly 4 effectively suppresses dust overflow.

[0026] See also Figure 1-Figure 4 ,in Figure 3 The direction of the middle arrow is the direction of laser emission. In this embodiment, the soft curtain assembly 4 includes a support plate 41 and a hanging curtain 42. A mounting groove 411 is provided on the lower side of the support plate 41. When the hanging curtain 42 is inserted into the mounting groove 411, a long axis 43 can pass through a hole 421 of the hanging curtain 42 from the side of the mounting groove 411. The specific soft curtain assembly 4 includes a support plate 41, a hanging curtain 42, and a long axis 43. By having the long axis 43 pass through the hole 421 of the hanging curtain 42 from the side of the mounting groove 411, the hanging curtain 42 can be effectively prevented from falling from the mounting groove 411. Thanks to the long axis 43, the hanging curtain 42 can rotate around the long axis 43 to a certain extent. When the soft curtain assembly 4 is installed, the hanging curtain 42 can completely cover the operating port 211. The hanging curtain 42 needs to completely cover the operating port 211, which can effectively prevent dust from overflowing from the lower side of the operating port 211. The marking machine 1 includes a laser emitting head 12, and the laser emitting head 12 is coaxially provided with a connecting pipe 22 facing the laser emitting direction. A flange 23 is provided at one end of the connecting pipe 22, and the connecting pipe 22 is fixed to the marking machine 1 through the flange 23. The outer ring of the connecting pipe 22 is provided with a thread 1, and the top of the isolation box 21 is provided with a connecting port 212, and a connecting pipe 24 can be inserted into the connecting port 212. The inner wall of the connecting pipe 24 is provided with a thread 2 that can match the thread 1. When the connecting pipe 1 22 is connected to the connecting pipe 2 24, the flange 25 at the bottom of the connecting pipe 2 24 can fit the inner wall of the isolation box 21. In order to facilitate the installation and disassembly of the isolation component 2, the connecting pipe 1 22 and the connecting pipe 2 24 are connected to each other. When the isolation component 2 is not needed, the connecting pipe 2 24 is rotated and twisted from the connecting pipe 1 22 to complete the disconnection of the isolation component 2 from the marking machine 1. At the same time, the connection between the connecting pipe 1 22 and the connecting pipe 2 24 can also effectively prevent dust from overflowing from the laser emission head 12.

[0027] See also Figure 5 In this embodiment, the orifice plate 11 includes a second hole 111, which is a threaded hole. The threaded hole structure of the second hole 111 facilitates securing the parts to be marked. It also serves as a dust channel, allowing the dust collection assembly 3 to smoothly absorb dust within the isolation assembly 2. The dust collection assembly 3 below the orifice plate 11 includes a dust collection tube 31 and a dust collector 32. One end of the dust collection tube 31 is connected to a bell mouth 311, which fits snugly against the bottom of the orifice plate 11 and completely covers the second hole 111 on the orifice plate 11. The bell mouth 311 completely covers the orifice plate 11 to prevent dust from escaping from the uncovered second hole 111. The isolation box 21 is constructed from brown, transparent acrylic panels. The laser emitter 12 can emit high-energy laser light, and the brown, transparent acrylic panels provide eye protection.

[0028] When working, the operator first prepares the parts to be marked, lifts the hanging curtain 42 in front of any operating port 211 of the isolation box 21, and uses the second hole 111 to fix the part on the orifice plate 11. Here, the operator can make different fixing parts according to the characteristics of the part, fix the fixing parts on the second hole 111 to clamp the part. In the case that the part itself has a hole, the bolt can be directly used to pass through the hole of the part itself and cooperate with the second hole 111 to fix it on the orifice plate 11. When the fixation is completed, the hand is taken out from the operating port 211, and the hanging curtain 42 falls under gravity, completely covering the operating port 211 to prevent dust from overflowing. Then the operator starts the marking machine 1, operates the marking program, and starts marking. The laser engraving generates dust on the surface of the part, and the dust suction component 3 under the marking machine 1 absorbs the dust in the isolation component 2. The specific method is that the vacuum cleaner 32 starts to work. The vacuum cleaner 32 here is a prior art, and its working principle is no longer described here. The vacuum cleaner 32 is connected Connect the dust suction pipe 31, and the bell mouth 311 of the dust suction pipe 31 is attached to the bottom of the orifice plate 11. The dust in the isolation assembly 2 is discharged from the second hole 111 to the dust collector 32, thus achieving the purpose of cleaning the inside of the isolation assembly 2. The advantage of using the soft curtain assembly 4 here is that the dust collector 32 absorbs dust, and a negative pressure will be formed in the isolation assembly 2. The hanging curtain 42 can swing slightly to allow the gas outside the isolation assembly 2 to enter and achieve air pressure balance. When facing parts of different heights, there is also a need to adjust the height of the laser transmitter head 12. Here, the threads between the connecting pipe 1 22 and the connecting pipe 2 24 can be twisted to make the isolation assembly 2 adaptable to different laser transmitter head 12 heights. When encountering large non-standard parts, the isolation assembly 2 can be completely removed. Here, the connecting pipe 2 24 is separated from the connecting pipe 1 22, and then the connecting pipe 2 24 is removed from the operation port 211, and then the isolation box 21 is picked up and moved away, thus completing the removal of the isolation assembly 2.

[0029] Through the above steps, the isolation component 2 on the marking machine 1 can effectively isolate the dust generated by the marking machine 1 during the marking operation. At the same time, the dust suction component 3 inside the marking machine 1 can suck away the dust in the isolation component 2. At the same time, the isolation component 2 includes an isolation box 21. An operation port 211 is opened on the side of the isolation box 21 for the user to place and take the parts to be marked. In order to prevent dust from overflowing from the operation port 211, a soft curtain component 4 is installed on the upper side of the operation port 211. The soft curtain component 4 effectively suppresses dust overflow to solve the problem that in actual production and manufacturing, the dust powder generated by the marking machine 1 does not fall directly into the funnel below the isolation net but is mixed in the air and floats away with the airflow or is inhaled into the lungs of the operator.
