Description

TECHNICAL FIELD

[0001] The utility model relates to laser equipment technical field, concretely relates to a laser protection cover and laser. BACKGROUND

[0002] In the automatic production line, often use laser equipment to mark or do cleaning, because laser itself power is high, high risk, the smoke waste gas produced in laser work is harmful to human body, so need to increase the protection cover and dust collection equipment, the traditional protection cover and dust collection equipment generally suck dust from one side or top of laser working surface, when the laser working surface is larger, the dust collection effect is poor, cannot effectively suck away harmful laser smoke, harms the health of operating personnel, simultaneously, the residual smoke is easy to adhere on the laser lens, pollutes the laser lens, influences the effect of laser processing. SUMMARY

[0003] In order to overcome the defects in the prior art, the utility model embodiment provides a laser protection cover and laser, can promote dust collection effect, prevent laser smoke from adhering to laser lens.

[0004] To achieve the above object, the utility model adopts the technical scheme that is:

[0005] The utility model discloses a laser protection cover, the laser protection cover is equipped between laser lens and laser working surface, and includes:

[0006] Shell, the shell top is equipped with the port, the port is communicated with laser lens, at least one blow -off port is equipped on the shell, and the shell outside gas source is communicated with the shell inside through at least one blow -off port, and the outside gas source blows gas towards the laser lens surface through at least one blow -off port;

[0007] Partition, the partition is equipped in the shell interior, the partition one side is surrounded and is formed with the first passageway communicated with laser working surface in laser working surface periphery, the cross section of first passageway gradually reduces from the one end close to laser working surface to the one end close to laser lens, the other side of the partition forms second passageway with the shell, the first passageway and second passageway are communicated with external dust collection equipment, and the cross section of second passageway gradually increases from the one end close to laser working surface to the one end close to laser lens.

[0008] The above technical solution, by setting an air blowing port on the protective housing, allows an external air source to blow air onto the laser lens when the laser is working, effectively preventing laser smoke from adhering to the laser lens and reducing the frequency of laser lens maintenance. At the same time, the cross-section of the second channel formed inside the housing gradually increases towards the end closer to the laser lens, so that the suction port of the dust collection equipment surrounds the periphery of the laser working surface, achieving better dust collection effect when using the same dust collection equipment.

[0009] Furthermore, the at least one air outlet is equipped with an air-blowing block, which has air-blowing holes. One end of each air-blowing hole is connected to an external air source, and the other end faces the laser lens. This allows the external air source to effectively blow air onto the laser lens through the air-blowing holes, preventing the smoke generated by the laser from adhering to the laser lens.

[0010] Furthermore, the air-blowing block is positioned near the top of the housing, and the pressure of the external air source connected to the air-blowing block is adjustable. The air-blowing block's proximity to the top of the housing and its closer proximity to the laser lens enhances the blowing effect of the external air source, while the adjustable external air source pressure more effectively prevents laser smoke.

[0011] Furthermore, the partition includes a first partition arranged laterally along the inner periphery of the housing and a second partition arranged axially along the channel. The second partition is connected to the first partition and located below the first partition. The formation of an independent suction channel by the first and second partitions improves suction performance.

[0012] Furthermore, the end of the second partition closest to the laser's working surface forms an angle with the housing. This results in a smaller cross-section of the formed first channel near the laser lens, without obstructing the laser beam.

[0013] Furthermore, the second partition has an inverted right-angled triangle shape on its side, with the right-angled side connected to the inner wall of the housing and the hypotenuse facing the channel. This shape of the second partition ensures a stable connection between the partition and the housing while also guaranteeing that the cross-section of the second channel gradually increases towards the laser lens, thus improving dust collection efficiency while maintaining channel stability.

[0014] Furthermore, both the side of the housing and the partition are provided with at least one interface, and the external vacuum cleaner is disposed on the side of the housing through communication with at least one interface. The vacuum cleaner is disposed on the side of the partition, so that the air intake of the vacuum cleaner surrounds the periphery of the laser working surface.

[0015] Furthermore, a cover plate is provided on the top of the housing, which abuts against the laser, and the port is located near the center of the cover plate. The cover plate's tight contact with the laser prevents light leakage during operation, reducing the laser's potential harm to the human body.

[0016] The second aspect of this utility model discloses a laser that uses a laser shield as described in any one of the first aspects.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] 1. This application provides an air blowing port on the protective housing. When the laser is working, an external air source can blow air onto the laser lens through the air blowing port, which can effectively prevent laser smoke from adhering to the laser lens and reduce the number of times the laser lens needs maintenance.

[0019] 2. This application forms a second channel inside the housing through a partition, and the cross-section of the second channel gradually increases towards the end closer to the laser lens, so that the suction port of the dust collection device surrounds the working surface of the laser. Under the condition of using the same dust collection device, a better dust collection effect can be achieved.

[0029] Reference Figures 1-3 This application provides a laser protective cover, which is disposed between the laser lens 2 and the laser working surface, and includes:

[0030] The housing 3 has a shape and size that can be flexibly set. The housing 3 is used to seal the space between the laser lens 2 and the laser working surface, so that the dust and smoke in the space can be extracted by the dust collection device 8.

[0031] In the embodiments of this application, the housing 3 is generally rectangular, and the interior of the housing 3 is a hollow cavity, such as... Figure 2 and Figure 3 As shown, the top of the housing 3 is provided with a cover plate 4, which abuts against the laser 1. The cover plate 4 is provided with a port, which is connected to the laser lens 2. The port is located near the middle of the cover plate 4, and the bottom of the housing 3 is located near the working surface of the laser.

[0032] In other possible embodiments, the bottom of the housing 3 may also directly cover the laser's working surface. The laser's working surface, as indicated by the arrow in the figure, is opposite to the plane where the cover plate 4 is located.

[0033] like Figure 1 As shown, the housing 3 is provided with an air blowing port, which is used to connect the external air source of the housing 3 and the inside of the housing 3. The external air source blows air toward the surface of the laser lens 2 through the air blowing port, thereby preventing the smoke generated by the laser from adhering to the laser lens 2.

[0034] In one possible embodiment, the air blowing port is provided with an air blowing block 5. The shape and size of the air blowing block 5 can be flexibly set. The air blowing block 5 is provided with an air blowing hole. One end of the air blowing hole is connected to an external air source, and the other end faces the laser lens 2, so that the external air source can blow air toward the surface of the laser lens 2 through the air blowing hole.

[0035] To enhance the blocking force, the air-blowing block 5 is positioned near the top of the housing 3, so that the end of the air-blowing hole facing the laser lens 2 is closer to the laser lens 2, and the pressure of the air source connected to the air-blowing block 5 is adjustable.

[0036] In one possible embodiment, the outer casing 3 is provided with a pipe, which is connected to the air blowing port. The compressed air connected to the outer pipe blows air towards the laser lens 2 through the air blowing block 5, forming a certain positive pressure near the laser lens 2 to prevent residual laser smoke from adhering to the laser lens 2. At the same time, the outer pipe is provided with a pressure regulating valve to adjust the airflow, thereby flexibly changing the magnitude of the positive pressure blown into the casing 3 according to the specific situation.

[0037] In other possible embodiments, the protective cover may be provided with two or more air inlets, which may be located at any position on the housing 3 near the top of the housing 3.

[0038] A partition is disposed inside the housing 3. One side of the partition forms a first channel around the laser's working surface, connecting to the laser's working surface and oriented axially towards the laser lens 2. The cross-section of the first channel gradually decreases from the end closer to the laser's working surface to the end closer to the laser lens 2. This first channel helps prevent smoke from escaping towards the laser lens 2. The other side of the partition forms a second channel with the housing. Both the first and second channels connect to an external vacuum cleaner 8. The cross-section of the second channel gradually increases from the end closer to the laser's working surface to the end closer to the laser lens 2. This structure allows the suction port of the vacuum cleaner 8 to surround the laser's working surface, resulting in stronger suction than traditional protective covers when using the same vacuum cleaner, with a more significant effect when the laser's working surface is large. It is understood that one side of the partition is opposite to the housing 3, and the other side is opposite to the housing 3.

[0039] like Figure 1 and Figure 2 As shown in the embodiment of this application, the partition is located below the air inlet and includes a first partition 6 arranged laterally along the inner periphery of the housing 3 and a second partition 7 arranged axially along the channel. The second partition 7 is connected to the first partition 6 and is located below the first partition 6.

[0040] In order to form the first channel and the second channel, as Figure 2 As shown, one side of the first partition 6 is connected to the inner wall of the housing 3, and the other side extends away from the inner wall of the housing 3 to connect with the second partition 7. The shape and size of the second partition 7 can be flexibly set so as to form the channel with the first partition 6.

[0041] In the embodiments of this application, the second partition 7 can be a rectangular plate or a prism with an inverted right-angled triangle on the side and a hollow interior. When the second partition 7 is a rectangular plate, there is an angle between the end of the second partition 7 near the working surface of the laser and the inner wall of the housing 3. The angle is set so that the degree to which the cross-section of the first channel gradually decreases will not affect the operation of the laser 1.

[0042] When the second partition 7 is a prism with an inverted right-angled triangle on the side and a hollow interior, the right-angled side of the inverted right-angled triangle is connected to the inner wall of the housing 3, the hypotenuse of the inverted right-angled triangle faces the channel, and the angle of the right-angled triangle is set so that the degree to which the cross-section of the first channel gradually decreases will not affect the operation of the laser 1.

[0043] like Figure 2 and Figure 3 Figure 3As shown, interfaces are provided on the side of the housing 3 and the second partition 7. The external vacuum cleaner 8 is connected to the interface and is located on the side of the housing 3. The first channel and the second channel are connected to the external vacuum cleaner through the interface, so as to achieve a better vacuuming effect in cooperation with the channel.

[0044] In other possible embodiments, the protective cover may be provided with two or more interfaces, which may be located at any position on the side of the housing 3 and the second partition 7.

[0045] In practical use, first install the laser protective cover described in the above embodiment below the laser lens 2, connect the air blowing block 5 to the external compressed air source, and connect the interface of the protective cover to the dust collection device 8. Before the laser 1 starts working, turn on the dust collection switch and the air blowing switch in advance. After the channel forms a stable negative pressure, the laser 1 starts working. After the laser 1 finishes working and is turned off, the dust collection device 8 needs to work for a period of time to prevent laser smoke from overflowing to the outside of the laser. During use, the airflow of the external compressed air source can be adjusted according to the actual situation through the pressure regulating valve.

[0046] The laser protective cover provided in this application embodiment has a simple structure and low cost. It can effectively prevent laser smoke from adhering to the laser lens, reduce the number of times the laser lens needs maintenance, and has a strong dust removal power. When using the same dust collection equipment, it can achieve better dust collection effect.

[0047] This application also provides a laser, which is dusted using the laser protective cover described in the above embodiments.

[0048] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
