Description

Technical Field

[0001] This application relates to the field of laser heads, and more specifically, to a laser head dustproof component and a laser head. Background Technology

[0002] In the design of laser heads, component contamination is a critical and unavoidable issue. For example, the cleanliness of the lens, a core component for laser emission and focusing, directly affects the performance and stability of the laser head. However, lenses are highly susceptible to contaminants such as dust and particles. Once these contaminants adhere to the lens surface, they cause laser scattering and energy loss, thus affecting the accuracy and efficiency of the laser head.

[0003] Currently, cavity sealing is commonly used to prevent dust from entering the lens mounting area, which effectively isolates external contaminants to a certain extent. However, existing transmission component designs present a significant technical challenge: achieving a complete seal between the motor drive cavity and the lens mounting cavity is difficult. Because the motor requires heat dissipation and a certain amount of movement space during operation, the sealing design of the drive cavity becomes exceptionally complex. If the seal is inadequate, dust and particles can penetrate the lens mounting area through tiny gaps, contaminating the lens and affecting the overall performance of the laser head. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a laser head dustproof component and a laser head, which can improve the dustproof effect of the laser head dustproof component.

[0005] In a first aspect, embodiments of this application provide a laser head dustproof assembly, including: a dustproof cover, a transmission element, and a dustproof sleeve; the transmission element penetrates two opposite surfaces of the dustproof cover; the transmission element extends from both ends of the dustproof cover and connects to an external drive structure; the dustproof sleeve is disposed outside the dustproof cover and is fitted onto the outer surface of the transmission element; wherein, the interior of the dustproof cover is configured to accommodate a target element, and the dustproof cover and the dustproof sleeve are configured to isolate the target element from the external space of the dustproof cover by cooperation.

[0006] In the above implementation process, the dust cover is used to provide a sealed space for the target component, and the dust sleeve is used to block the gap between the transmission component and the dust cover. By setting the dust sleeve and dust cover together, the target component can be completely isolated from the external space of the dust cover, reducing the risk of dust and other impurities entering the dust cover and improving the dustproof effect of the laser head dustproof component.

[0007] In one embodiment, it further includes: a transmission sleeve; the transmission element passes through the target element; the transmission sleeve is disposed outside the target element; the transmission sleeve is sleeved on the outer surface of the transmission element; wherein the transmission sleeve is configured to fix the target element onto the transmission element.

[0008] In the above implementation process, by using a transmission sleeve to fix the target component to the transmission component, compared with the traditional fixing method of screws, bolts and other methods, the generation of impurities can be reduced and the cleanliness inside the dust cover can be improved.

[0009] In one embodiment, the transmission element has a stepped structure; the transmission element includes a large-diameter portion and a small-diameter portion, and the large-diameter portion and the small-diameter portion are fixedly connected; the small-diameter portion passes through the target element; the large-diameter portion is located on one side of the target element; the transmission sleeve is fitted onto the outer surface of the small-diameter portion of the transmission element.

[0010] In the above implementation process, by setting the transmission element as a stepped structure, the transmission sleeve is fitted onto the outer surface of the transmission element. The target element is fixed to the transmission element through the cooperation of the transmission sleeve and the large-diameter portion of the transmission element. On the one hand, compared to traditional fixing methods using screws and bolts, this reduces the generation of impurities and improves the cleanliness inside the dust cover. On the other hand, the cooperation between the large-diameter portion of the transmission element and the transmission sleeve reduces the design and installation difficulty of the transmission sleeve, improving the installation efficiency.

[0011] In one embodiment, it further includes: a transmission plate; the transmission plate includes a bottom surface, a top surface, and a side surface; the two ends of the side surface are respectively connected to the bottom surface and the top surface; the two ends of the transmission element extending out of the dust cover are respectively connected to the bottom surface and the top surface; and a drive assembly is connected to the side of the top surface of the transmission plate away from the bottom surface.

[0012] In the above implementation process, by setting the transmission element to connect with the bottom and top surfaces of the transmission plate, the dust cover can be further isolated from the external space through the top and bottom surfaces of the transmission plate, thereby improving the dustproof performance of the laser head dustproof assembly.

[0013] In one embodiment, it further includes: a fixing cover; the fixing cover is disposed at the connection between the transmission element and the transmission plate; wherein the fixing cover is configured to fix the transmission element and the transmission plate.

[0014] In the above implementation process, by setting a fixed cover, the connection between the transmission element and the transmission plate is blocked, thereby preventing impurities generated by the connection between the transmission element and the transmission plate from falling into the dust cover, thus improving the dustproof capability of the laser head dustproof assembly.

[0015] In one embodiment, the transmission element is a shaft; and / or the target element is a mirror mount.

[0016] In the above implementation process, due to the advantages of shafts such as simple structure, easy maintenance, and strong load-bearing capacity, setting the transmission element as a shaft can simplify the structure of the transmission element, reduce the maintenance difficulty of the transmission element, and improve the load-bearing capacity of the transmission element. Furthermore, in the operation of the laser head, the cleanliness of the lens is a crucial factor affecting the lens's working performance. By setting the target element as the lens mount, the laser head dustproof component provides a clean environment for the lens mount, ensuring the lens remains in a clean environment and thus improving the lens's working performance.

[0017] Secondly, embodiments of this application also provide a laser head, including: a dustproof component and a driving component as described in the first aspect or any one of the first aspects; the dustproof component is connected to the driving component; wherein the driving component is configured to drive some or all of the components inside the dustproof component.

[0018] In the above implementation process, the dust cover provides a sealed space for the target component, and the dust sleeve covers the gap between the transmission component and the dust cover. By using the dust sleeve and dust cover together, the target component can be completely isolated from the external space of the dust cover, reducing the risk of dust and other impurities entering the dust cover and improving the dustproof effect of the laser head dustproof assembly. In addition, by connecting the drive component to the dustproof assembly, the force or torque generated by the drive component can be transmitted to the internal components of the dustproof assembly, thereby adjusting the position of the target component inside the dustproof assembly and improving the adjustment flexibility of the target component.

[0019] In one embodiment, the driving assembly includes: a driving element, a slider, and a guide rail; the slider is disposed on the guide rail; the driving element is connected to the slider; wherein the driving element is configured to drive the slider to move on the guide rail.

[0020] In the above implementation process, by setting up sliding parts and guide rails, the power or torque generated by the drive component can be transmitted to the dustproof component through the sliding parts, thereby improving the driving force of the drive component.

[0021] In one embodiment, the driving component further includes: a limiting member; the limiting member is disposed on the guide rail; wherein the limiting member is configured to limit the sliding member.

[0022] In the above implementation process, by setting a limiting component on the guide rail, the sliding position of the slider can be restricted by the limiting component, thereby improving the sliding accuracy of the slider.

[0023] In one embodiment, it further includes: a device housing; both the dustproof assembly and the drive assembly are disposed inside the device housing; the device housing is provided with a through hole; and the portion of the target element in the dustproof assembly located at the opening of the dustproof cover is disposed outside the device housing through the through hole.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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.

[0035] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] In the description of this application, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed when in use.

Therefore, they should not be construed as limitations of this application.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] Laser heads typically contain multiple precision components, such as lenses, mirrors, and reflectors, which need to be precisely mounted in specific positions to ensure correct transmission and focusing of the laser beam. These lenses are usually made of high-purity materials, such as silicon dioxide or zinc selenide crystals, which have high refractive index and low scattering rate to ensure effective focusing and diffusion of the laser beam. However, these lenses are very sensitive to the external environment; dust, impurities, or moisture can damage or contaminate them, affecting the laser's performance and stability. Therefore, it is necessary to design the lenses and mounting cavity to be completely sealed to protect them from external environmental damage.

[0039] However, in practical applications, the seal between the lens and the cavity is often affected by a variety of factors. For example, temperature changes may cause a mismatch in the coefficients of thermal expansion between the lens and the cavity, resulting in gaps; dust, moisture, and other contaminants may also enter the cavity through tiny gaps, affecting the performance and stability of the laser.

[0040] In view of this, this application proposes a laser head dustproof assembly. In this assembly, the dust cover is used to provide a sealed space for the target component, and the dust sleeve is used to block the gap between the transmission component and the dust cover. By setting the dust sleeve and the dust cover together, the target component can be completely isolated from the external space of the dust cover, reducing the risk of dust and other impurities entering the dust cover and improving the dustproof effect of the laser head dustproof assembly.

[0041] like Figure 1 The diagram shown is a schematic of a laser head dustproof assembly provided in an embodiment of this application, including: a dust cover 100, a transmission element 200, and a dust sleeve 300.

[0042] The transmission element 200 passes through the two opposite surfaces of the dust cover 100; the transmission element 200 extends out of the two ends of the dust cover 100 and connects to the external drive structure; the dust cover 300 is disposed outside the dust cover 100 and is fitted on the outer surface of the transmission element 200.

[0043] The interior of the dust cover 100 is configured to accommodate the target component 20, and the dust cover 100 and the dust sleeve 300 are configured to isolate the target component 20 from the external space of the dust cover 100 by means of cooperation.

[0044] Optionally, the target element 20 can be one or more components in the laser head that require dust protection. For example, lenses, lens mounts, etc. The target element 20 can be selected according to the actual situation.

[0045] The aforementioned transmission element 200 refers to an element used to transmit power or torque. Examples include drive shafts and drive wheels.

[0046] Optionally, the dust cover 100 can be a fully enclosed structure or a semi-enclosed structure. The dust cover 100 can be a hollow cube, a hollow cuboid, a hollow cylinder, or other structures, and the structure of the dust cover 100 can be selected according to the actual situation.

[0047] Understandably, when the transmission element 200 penetrates two opposite surfaces of the dust cover 100, the outer surface of the transmission element 200 contacts the inner surface of the hole on the surface of the dust cover 100 through which it penetrates, so as to reduce the gap between the transmission element 200 and the corresponding surface of the dust cover 100 and improve the dustproof effect.

[0048] In one embodiment, the dust cover 300 is disposed on the portion of the transmission element 200 that extends out of the dust cover 100.

[0049] It should be understood that although the outer diameter of the transmission element 200 can be set to be equal to the inner diameter of the hole through the surface of the dust cover 100, or the outer diameter of the transmission element 200 can be slightly larger than the inner diameter of the hole through the surface of the dust cover 100, due to machining errors or calculation errors, gaps may exist between the transmission element 200 and the hole on the surface of the dust cover 100. Dust and other impurities from outside the dust cover 100 may enter the interior of the dust cover 100 through these gaps. By fitting a dust cover 300 over the portion of the transmission element 200 extending beyond the dust cover 100, the dust cover 300 can effectively block the gap between the surfaces of the transmission element 200 and the dust cover 100, further improving the dustproof effect of the dust cover 300.

[0050] Optionally, the dust cover 300 can be made of rubber, plastic, silicone, etc., and the material of the dust cover 300 can be selected according to the actual situation.

[0051] In the above implementation process, the dust cover 100 is used to provide a sealed space for the target component 20, and the dust sleeve 300 is used to cover the gap between the transmission component 200 and the dust cover 100. By setting the dust sleeve 300 and the dust cover 100 together, the target component 20 can be completely isolated from the external space of the dust cover 100, reducing the risk of dust and other impurities entering the inside of the dust cover 100 and improving the dustproof effect of the laser head dustproof assembly.

[0052] In one possible implementation, such as Figure 2 As shown, the laser head dustproof assembly also includes a transmission sleeve 400.

[0053] The transmission element 200 penetrates the target element 20; the transmission sleeve 400 is disposed on the outside of the target element 20; the transmission sleeve 400 is sleeved on the outer surface of the transmission element 200.

[0054] Understandably, after the transmission element 200 passes through the target element 20, the target element 20 needs to be fixed to the transmission element 200. If screws, bolts or other fixing methods are used, metal impurities may be generated during the fixing or loosening process. These metal impurities may fall onto the target element 20, thereby affecting the working effect of the target element 20.

[0055] A transmission sleeve 400 is provided, which is disposed outside the target element 20 and sleeved on the outer surface of the transmission element 200. The transmission sleeve 400 can be configured to fix the target element 20 to the transmission element.

[0056] Specifically, if the transmission element 200 has a uniform thickness, two transmission sleeves 400 can be provided, with the length of each sleeve being the length from the outer surface of the target element 20 to its corresponding end. The target element 20 is fixed at the set position of the transmission element 200 by the interaction force between the two sleeves 400.

[0057] If the transmission element 200 has a non-uniform diameter structure, such as a stepped structure, a transmission sleeve 400 can be provided. This transmission sleeve 400 is located at the end of the transmission element 200 with a relatively smaller diameter, and its length is the length from the outer surface of the target element 20 extending to the corresponding end of the target element 20 at the smaller diameter end. The target element 20 is fixed at the direct boundary between the sizes of the transmission element 200 and the transmission element 200 by the transmission sleeve 400 and the larger diameter portion 210 of the target element 200.

[0058] The above-described configuration of the transmission sleeve 400 is merely exemplary, and the configuration of the transmission sleeve 400 can be selected according to the actual situation.

[0059] Optionally, the material of the transmission sleeve 400 can be rubber, plastic, silicone, metal, etc., and the material of the transmission sleeve 400 can be selected according to the actual situation.

[0060] In the above implementation process, by using the transmission sleeve 400 to fix the target element 20 onto the transmission element 200, compared with the traditional fixing method using screws, bolts, etc., the generation of impurities can be reduced and the cleanliness inside the dust cover 100 can be improved.

[0061] In one possible implementation, such as Figure 3 As shown, the transmission element 200 has a stepped structure; the transmission element 200 includes a large-diameter portion 210 and a small-diameter portion 220, and the large-diameter portion 210 and the small-diameter portion 220 are fixedly connected.

[0062] The small-diameter portion 220 penetrates the target element 20; the large-diameter portion 210 is located on one side of the target element 20; and the transmission sleeve 400 is fitted onto the outer surface of the small-diameter portion 220 of the transmission element 200.

[0063] The diameter of the large-diameter portion 210 here is larger than the diameter of the through hole on the target element 20.

[0064] Understandably, the small-diameter portion 220 of the transmission element 200 passes through the target element 20, and the target element 20 is held in place by the large-diameter portion 210. In order to fix the transmission element 200 at the junction of the large-diameter portion 210 and the small-diameter portion 220, a transmission sleeve 400 can be fitted onto the outer surface of the small-diameter portion 220, and the target element 20 is fixed to the transmission element 200 by the interaction force between the transmission sleeve 400 and the large-diameter portion 210.

[0065] In the above implementation process, by setting the transmission element 200 as a stepped structure, the transmission sleeve 400 is fitted onto the outer surface of the transmission element 200. Through the cooperation between the transmission sleeve 400 and the large-diameter portion 210 of the transmission element 200, the target element 20 is fixed to the transmission element 200. On the one hand, compared to traditional fixing methods using screws, bolts, etc., this reduces the generation of impurities and improves the cleanliness inside the dust cover 100. On the other hand, the cooperation between the large-diameter portion 210 of the transmission element 200 and the transmission sleeve 400 reduces the design and installation difficulty of the transmission sleeve 400 and improves its installation efficiency.

[0066] In one possible implementation, the laser head dustproof assembly also includes a transmission plate 500.

[0067] The transmission plate 500 includes a bottom surface, a top surface, and a side surface; the two ends of the side surface are connected to the bottom surface and the top surface, respectively; the two ends of the transmission element 200 extending from the dust cover 100 are connected to the bottom surface and the top surface, respectively; the top surface of the transmission plate 500 away from the bottom surface is connected to the drive assembly.

[0068] Optionally, the side and bottom surfaces can be designed as a single unit. The side and bottom surfaces, and the side and top surfaces can be welded together, or the side and bottom surfaces, and the side and top surfaces can be connected by screws, etc. The connection method of the side and bottom surfaces can be selected according to the actual situation.

[0069] The transmission element 200 here can be connected to the transmission plate 500 by means of screws, bolts, snap-fit, welding, etc. The connection method between the transmission element 200 and the transmission plate 500 can be selected according to the actual situation.

[0070] In the above implementation process, by setting the transmission element 200 to be connected to the bottom and top surfaces of the transmission plate 500, the dust cover 100 can be further isolated from the external space through the top and bottom surfaces of the transmission plate 500, thereby improving the dustproof performance of the laser head dustproof assembly.

[0071] In one possible implementation, the laser head dustproof assembly also includes a fixing cover 600.

[0072] The fixed cover 600 is located at the connection between the transmission element 200 and the transmission plate 500.

[0073] The fixed cover 600 here is configured to fix the transmission element 200 and the transmission plate 500.

[0074] Optionally, the material of the fixing cover 600 can be rubber, metal, plastic, etc., and the material of the fixing cover 600 can be selected according to the actual situation.

[0075] In one embodiment, the fixed cover 600 is provided with a through hole, the inner diameter of which is equal to the outer diameter of the transmission element 200. The through hole is configured to allow the transmission element 200 to pass through.

[0076] The fixed cover 600 here is configured to cover the connection between the transmission element 200 and the transmission plate 500, so as to prevent impurities generated by the connection between the transmission element 200 and the transmission plate 500 from falling into the dust cover 100.

[0077] In the above implementation process, by setting a fixed cover 600, the connection between the transmission element 200 and the transmission plate 500 is blocked, thereby preventing impurities generated by the connection between the transmission element 200 and the transmission plate 500 from falling into the dust cover 100, thus improving the dustproof capability of the laser head dustproof assembly.

[0078] In one possible implementation, the transmission element 200 is a shaft; and / or the target element 20 is a mirror mount.

[0079] The lens mount here is configured to hold the lens.

[0080] Understandably, lenses play a crucial role in laser heads, such as focusing and protection. Impurities on the lenses can affect their functionality, thus impacting the laser head's performance.

[0081] The laser head dustproof component is configured to isolate the lens mount from the external environment, thus keeping the lens mount in a clean environment and preventing impurities from appearing on the lens, thereby improving the lens's performance.

[0082] In the above implementation process, since shafts have advantages such as simple structure, easy maintenance, and strong load-bearing capacity, setting the transmission element 200 as a shaft can simplify the structure of the transmission element 200, reduce the maintenance difficulty of the transmission element 200, and improve the load-bearing capacity of the transmission element 200. Furthermore, in the operation of the laser head, the cleanliness of the lens is a crucial factor affecting the lens's working performance. By setting the target element 20 as a lens mount, the laser head dustproof assembly provides a clean environment for the lens mount, ensuring the lens remains in a clean environment and thus improving the lens's working performance.

[0083] like Figure 4 The diagram shown is a schematic diagram of a laser head provided in an embodiment of this application, including: the dustproof component and the driving component in the above embodiment.

[0084] The dustproof component is connected to the drive component.

[0085] The drive component here is configured to drive some or all of the components inside the dustproof assembly. For example, the drive component can be a lead screw motor, driver, stepper motor, etc. The drive component can be selected according to the actual situation.

[0086] Understandably, the drive assembly is connected to the transmission element 200 in the dustproof assembly, and transmits power or torque through the transmission element 200 to drive the target element 20 located in the dustproof assembly to move.

[0087] The aforementioned drive assembly is configured to adjust the position of the target element 20 by transmitting power or torque to the target element 20.

[0088] For example, if the target element 20 is a lens mount, the drive assembly is configured to adjust the position of the lens mount by transmitting power or torque to the lens mount, thereby adjusting the focal length of the lens mounted on the lens mount.

[0089] In the above implementation process, the dust cover 100 provides a sealed space for the target component 20, and the dust sleeve 300 covers the gap between the transmission component 200 and the dust cover 100. By setting the dust sleeve 300 and the dust cover 100 together, the target component 20 can be completely isolated from the external space of the dust cover 100, reducing the risk of dust and other impurities entering the dust cover 100 and improving the dustproof effect of the laser head dustproof assembly. In addition, by connecting the drive assembly to the dustproof assembly, the force or torque generated by the drive assembly can be transmitted to the internal components of the dustproof assembly, thereby adjusting the position of the target component 20 inside the dustproof assembly and improving the adjustment flexibility of the target component 20.

[0090] In one possible implementation, such as Figure 4 As shown, the drive assembly includes: a drive element 710, a slider 720, and a guide rail 730.

[0091] The slider 720 is mounted on the guide rail 730; the drive element 710 is connected to the slider 720.

[0092] In one embodiment, the guide rail 730 is provided with a plane for mounting the drive element 710. The guide rail 730 is a linear guide rail 730.

[0093] The slider 720 here is a component that can slide on the guide rail 730. For example, a slider, pulley, etc. The slider 720 can be selected according to the actual situation.

[0094] The aforementioned driving element 710 is configured to drive the slider 720 to move on the guide rail 730.

[0095] Understandably, the drive element 710 is connected to the dustproof assembly via the slider 720.

[0096] In the above implementation process, by setting the slider 720 and the guide rail 730, the power or torque generated by the drive component can be transmitted to the dustproof component through the slider 720, thereby improving the driving force of the drive component.

[0097] In one possible implementation, the driving component also includes a limiting element.

[0098] The limiting component is located on the guide rail 730.

[0099] The limiting component here is configured to limit the sliding component 720.

[0100] Optionally, the limiting element can be a proximity switch, limit switch, or other similar component, and the limiting element can be selected according to the actual situation.

[0101] It should be understood that by setting the limiting member on the guide rail 730, when the slider 720 slides on the guide rail 730, the limiting member can limit the slider 720 to control the sliding position of the slider 720.

[0102] In the above implementation process, by setting a limiting member on the guide rail 730, the sliding position of the slider 720 can be restricted by the limiting member, thereby improving the sliding accuracy of the slider 720.

[0103] In one possible implementation, such as Figure 5 As shown, the laser head also includes: a device housing 40.

[0104] The dustproof component and the drive component are both located inside the device housing 40; the device housing 40 is provided with a through hole; the portion of the target element 20 in the dustproof component located at the opening of the dust cover 100 is located outside the device housing 40 through the through hole.

[0105] The structure of the target element 20 in the dustproof assembly extends outside the device housing 40 through a through hole, which allows for the installation or removal of components or parts in the target element 20, thus improving the flexibility of loading and unloading the target element 20.

[0106] In the above implementation process, by providing a through hole on the device housing 40, the portion of the target element 20 in the dustproof assembly located at the opening of the dust cover 100 is located outside the device housing 40 through the through hole. The components or parts in the target element 20 can be installed or removed through the through hole, thereby improving the flexibility of loading and unloading the components or parts in the target element 20.
