Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical adjustment technology, and more specifically, to an adjustment mechanism and an optical processing head. Background Technology
[0002] In commonly used adjustment mechanisms, the adjustment of the target adjustment component is mainly achieved by pushing the target adjustment component to change its position, and by using the elasticity of elastic components such as compression springs or tension springs to restore the position of the target adjustment component.
[0003] However, elastic elements such as springs or tension springs usually have a certain length in the direction of their elastic force, which makes these elastic elements occupy too much space in the adjustment mechanism. Utility Model Content
[0004] The purpose of this application is to provide an adjustment mechanism and an optical processing head, which can reduce the space occupied in the adjustment mechanism by using a sheet-like elastic element.
[0005] In a first aspect, this application provides an adjustment mechanism, including a main body, a target adjustment member, a sheet-like elastic member, and a first pushing member; the main body is provided with a receiving chamber and a first adjustment hole; the target adjustment member is disposed in the receiving chamber and is movable along the bottom wall of the receiving chamber; both ends of the sheet-like elastic member are connected to the side walls of the receiving chamber; the middle section of the sheet-like elastic member abuts against the target adjustment member; the first adjustment hole extends into the receiving chamber; the first pushing member is disposed in the first adjustment hole and is movable along the axial direction of the first adjustment hole; the first pushing member is configured to push the target adjustment member to move along the bottom wall of the receiving chamber and squeeze the sheet-like elastic member; or release the target adjustment member.
[0006] The aforementioned adjustment mechanism uses sheet-like elastic elements as the elastic elements required in the adjustment mechanism. Compared with elastic elements such as springs and tension springs, the elastic force of sheet-like elastic elements is not in the direction of their length or width. Therefore, while achieving the adjustment of the target adjustment element in the adjustment mechanism through elastic force, the elastic element occupies less space, which makes it easier to arrange the internal space of the adjustment mechanism and reduce the size of the adjustment mechanism.
[0007] In conjunction with the first aspect, optionally, at least one end of the sheet-like elastic member is movably connected to the side wall of the receiving chamber; wherein the movable direction of the end of the sheet-like elastic member is parallel to the plane of the bottom wall of the receiving chamber.
[0008] In the aforementioned adjustment mechanism, where at least one end of the sheet-like elastic element is movably connected to the side wall of the receiving chamber, the sheet-like elastic element can specifically be a metal sheet that does not exhibit significant expansion or contraction. Compared to plastic sheets such as silicone, this type of metal sheet has a longer service life, meaning it can maintain its elastic coefficient for a longer period. This ensures the adjustment accuracy of the mechanism over a longer time and extends its service life.
[0009] In conjunction with the first aspect, optionally, the mechanism further includes at least one locking pin; the side wall of the receiving chamber is provided with a locking pin hole; wherein the axial direction of the locking pin hole intersects with the plane containing the bottom wall of the receiving chamber; the locking pin is located in the locking pin hole; the end of the sheet-like elastic element is located in the gap between the side of the locking pin and the side wall of the receiving chamber.
[0010] The aforementioned adjustment mechanism simplifies the movable connection of the end of the sheet-like elastic element by using a locking pin to press the end of the sheet-like elastic element against the side wall of the receiving chamber, thereby simplifying the structure of the adjustment mechanism.
[0011] In conjunction with the first aspect, optionally, the sheet-like elastic element includes a spring sheet.
[0012] The aforementioned adjustment mechanism uses metal springs or other non-expanding springs as the specific sheet-like springs, which have stronger fatigue resistance, thereby ensuring that the adjustment mechanism maintains a consistent reset force throughout its service life, guaranteeing long-term adjustment accuracy and reliability.
[0013] In conjunction with the first aspect, optionally, the side wall of the receiving chamber is provided with a groove; the projection of the sheet-like elastic element on the side wall along the direction of movement of the target adjusting element is located within the groove.
[0014] In the aforementioned adjustment mechanism, during the process of the sheet-like elastic element being pushed against by the target adjustment element, the middle section of the sheet-like elastic element usually moves towards the side wall of the receiving chamber. Therefore, to avoid the middle section of the sheet-like elastic element being restricted by the side wall of the receiving chamber, a groove is provided on the side wall as a clearance space, thereby expanding the adjustable range of the adjustment mechanism.
[0015] In conjunction with the first aspect, optionally, the number of the sheet-like elastic elements is two or more; the arrangement direction of the two or more sheet-like elastic elements intersects with the plane of the bottom wall of the receiving chamber.
[0016] The aforementioned adjustment mechanism, by incorporating at least two sheet-like elastic elements, increases the number of contact points between each element and the target adjustment element. This ensures that the direction of the target adjustment element's movement is more controllable by applying elastic force to the sheet-like elastic elements. Ultimately, this further improves the reliability and adjustment accuracy of the adjustment mechanism.
[0017] In conjunction with the first aspect, optionally, the mechanism further includes a second pushing member; the main body is also provided with a second adjusting hole; the second adjusting hole communicates with the receiving chamber; the second pushing member is disposed in the second adjusting hole and is movable along the axial direction of the second adjusting hole; the second pushing member is configured to push the target adjusting member to move along the bottom wall of the receiving chamber and squeeze the sheet-like elastic member; or release the target adjusting member; wherein the axial direction of the first adjusting hole intersects the axial direction of the second adjusting hole.
[0018] The aforementioned adjustment mechanism, by adding a second pusher and a second adjustment hole on top of the first pusher and the first adjustment hole, enables the target adjustment component to be adjusted in two directions within the plane of the bottom wall of the receiving compartment. This expands the adjustable range of the adjustment mechanism and further improves its applicability and convenience.
[0019] In conjunction with the first aspect, optionally, the axial direction of the first adjusting hole is perpendicular to the axial direction of the second adjusting hole.
[0020] The aforementioned adjustment mechanism, with its design where the axis of the first adjustment hole is perpendicular to the axis of the second adjustment hole, allows for a more intuitive determination of whether to adjust the target adjustment component alone or in combination, based on the target adjustment component's position relative to the main body. This further enhances the ease of use of the adjustment mechanism.
[0021] In conjunction with the first aspect, optionally, the inner wall of the first adjusting hole is provided with a first internal thread, and the first pushing member is provided with an external thread adapted to the first internal thread; and / or the inner wall of the second adjusting hole is provided with a second internal thread, and the second pushing member is provided with an external thread adapted to the second internal thread.
[0022] The aforementioned adjustment mechanism, when adjusting the target adjusting component, can rotate the first and / or second pushing components to move them forward or backward, converting a large amount of operation into a small amount of displacement for the first and / or second pushing components, thereby improving the adjustment accuracy of the mechanism. Furthermore, the fit between the internal and external threads allows the first and / or second pushing components to achieve self-locking in any position.
[0023] In conjunction with the first aspect, optionally, the target adjustment member includes a body and a connecting portion; the connecting portion extends outward from the side of the body near the sheet-like elastic member in a direction toward the sheet-like elastic member; the connecting portion is provided with a waist hole; the axial direction of the waist hole is perpendicular to the plane of the bottom wall of the receiving compartment, and when the sheet-like elastic member does not deform, the guiding direction of the waist hole is parallel to the angle bisector of the angle between the axial direction of the first adjustment hole and the axial direction of the second adjustment hole; the mechanism further includes a connecting pin; the side wall of the receiving compartment is provided with a connecting pin hole whose axial direction is parallel to the axial direction of the waist hole; the connecting pin is located in the waist hole and the connecting pin hole.
[0024] The aforementioned adjustment mechanism connects to the side wall of the receiving compartment through the waist hole on the target adjustment component, limiting controllable tilting, rotation, or jamming when the target adjustment component is pushed, thereby ensuring that the adjustment process proceeds as expected, which also improves the reliability of the adjustment mechanism.
[0025] In conjunction with the first aspect, optionally, the main body includes a base and a side cover; the base includes the bottom wall of the receiving compartment; both ends of the sheet-like elastic member are connected to the inner wall of the side cover; the side cover and the base are detachably connected.
[0026] The aforementioned adjustment mechanism, through a detachable connection between the base and the side cover, allows the receiving compartment to be opened, enabling the replacement of the target adjustment component within the compartment while it is open. For example, when the target adjustment component is specifically an optical lens and a lens mount, optical lenses with different parameters can be replaced as needed.
[0027] Secondly, embodiments of this application provide an optical processing head, including the adjustment mechanism described above; wherein, the target adjustment component of the adjustment mechanism includes an optical lens assembly; the light-transmitting surface of the optical lens assembly is parallel to the plane of the bottom wall of the receiving chamber of the adjustment mechanism.
[0028] The aforementioned optical processing head has the same beneficial effects as the first aspect or any optional embodiment of the first aspect, which will not be repeated here. Attached Figure Description

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0034] It should be noted that similar labels 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.
[0035] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "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 commonly used when the utility model product is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element 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 this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0036] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" 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 of 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] Please refer to Figure 1 and Figure 2 , Figure 1 This is a perspective view of the adjustment mechanism 100 provided in the embodiments of this application; Figure 2 This is an exploded view of the adjustment mechanism 100 provided in the embodiments of this application. The adjustment mechanism 100 provided in the embodiments of this application includes a main body 110, a target adjustment member 120, a sheet-like elastic member 130, and a first pushing member 140.
[0039] The main body 110 is provided with a receiving chamber and a first adjustment hole 1111. A target adjustment component 120 is disposed in the receiving chamber and can move along the bottom wall of the receiving chamber. The target adjustment component 120 can specifically be an optical lens and mount, a displacement sensor, or a valve, etc. The fact that the target adjustment component 120 can move along the bottom wall of the receiving chamber means that its position is adjustable within the plane of the bottom wall of the receiving chamber.
[0040] The two ends of the sheet-like elastic element 130 are connected to the side walls of the receiving chamber. The middle section of the sheet-like elastic element 130 abuts against the target adjustment element 120. The sheet-like elastic element 130 can be a metal sheet or a flexible plastic sheet such as silicone. The metal sheet mainly generates elasticity based on its own bending, while the flexible plastic sheet mainly generates elasticity based on its stretching. When the target adjustment element 120 pushes against the sheet-like elastic element 130 by movement, the sheet-like elastic element 130 can generate an elastic force to reset the target adjustment element 120. When the sheet-like elastic element 130 is specifically a metal sheet, since metal sheets are generally difficult to stretch, at least one end of the sheet-like elastic element 130 needs to be movably connected to the side wall of the receiving chamber. When the sheet-like elastic element 130 is pushed and deformed, one or both movably connected ends of the sheet-like elastic element 130 will be displaced. When the sheet elastic element 130 is specifically a flexible plastic sheet such as silicone, both ends of the sheet elastic element 130 can be fixedly connected to the side wall of the receiving chamber. When the sheet elastic element 130 is pushed and deformed, since both ends of the sheet elastic element 130 are fixedly connected, the sheet elastic element 130 will be stretched, thereby generating elastic force.
[0041] The first adjusting hole 1111 extends into the receiving chamber. The first pushing member 140 is disposed in the first adjusting hole 1111 and can move along the axial direction of the first adjusting hole 1111. Specifically, the first adjusting hole 1111 can be a through hole provided on the main body 110, and its axial direction can be parallel to the plane of the bottom wall of the receiving chamber or form an acute angle with the plane of the bottom wall of the receiving chamber. The first adjusting hole 1111 is located on the side of the main body 110 away from where the sheet-like elastic member 130 is disposed. The inner wall of the first adjusting hole 1111 can be smooth, and correspondingly, the first pushing member 140 can also be smooth. The first pushing member 140 can directly translate within the first adjusting hole 1111. The inner wall of the first adjusting hole 1111 can also be provided with internal threads, and correspondingly, the outer surface of the first pushing member 140 can be provided with external threads. The first pushing member 140 achieves translation along the axial direction of the first adjusting hole 1111 by rotating within the first adjusting hole 1111.
[0042] The first pusher 140 is configured to push the target adjustment member 120 along the bottom wall of the receiving chamber and compress the sheet-like elastic member 130, or release the target adjustment member 120. When the first pusher 140 moves towards the target adjustment member 120 within the first adjustment hole 1111, the first pusher 140 abuts against the target adjustment member 120 and applies a pushing force to it. Under the action of this pushing force, the target adjustment member 120 moves towards the sheet-like elastic member 130 and compresses its middle section, thereby storing elastic potential energy in the sheet-like elastic member 130. When the first pusher 140 moves away from the target adjustment member 120 within the first adjustment hole 1111, it releases the target adjustment member 120. The sheet-like elastic member 130 also releases its elastic potential energy, causing the target adjustment member 120 to move back to its initial position.
[0043] In the above implementation process, by using a sheet-like elastic element 130 as the elastic element required in the adjustment mechanism 100, compared with elastic elements such as springs and tension springs, the elastic force direction of the sheet-like elastic element 130 is not in its length or width direction. Therefore, on the basis of realizing the adjustment of the target adjustment element 120 in the adjustment mechanism 100 by elastic force, the elastic element occupies less space, which also makes it easier to arrange the internal space of the adjustment mechanism 100 and reduce the size of the adjustment mechanism 100.
[0044] Please refer to Figure 2 and Figure 3 , Figure 3 It is along Figure 1 The first type of horizontal plane cut cross-sectional view. In some optional embodiments, at least one end of the sheet-like elastic member 130 is movably connected to the side wall of the receiving chamber. The movable direction of the end of the sheet-like elastic member 130 is parallel to the plane containing the bottom wall of the receiving chamber. For example, if the sheet-like elastic member 130 is rectangular, and the long side of the rectangle is parallel to the plane containing the bottom wall of the receiving chamber, then the movable direction of the end of the sheet-like elastic member is parallel to the plane defined by the long side of the rectangle, which is also parallel to the plane containing the bottom wall of the receiving chamber.
[0045] With at least one end of the sheet-like elastic element 130 movably connected to the side wall of the receiving chamber, in conjunction with the foregoing description, the sheet-like elastic element 130 may specifically be a metal sheet that is not normally telescopic.
[0046] In the above implementation process, when at least one end of the sheet-like elastic element 130 is movably connected to the side wall of the receiving chamber, the sheet-like elastic element 130 can specifically be a metal sheet that does not exhibit significant expansion or contraction. Compared to plastic sheets such as silicone, this type of metal sheet has a longer service life, meaning it can maintain its elastic coefficient for a longer period. This ensures the adjustment accuracy of the adjustment mechanism 100 over a longer time, thus extending its service life.
[0047] Please continue to refer to Figure 2 and Figure 3 In some optional implementations, the adjustment mechanism 100 provided in this application embodiment further includes at least one locking pin 150.
[0048] The side wall of the receiving compartment is provided with locking holes. The axial direction of the locking holes intersects the plane containing the bottom wall of the receiving compartment. Locking pin 150 is located within the locking holes. That is, when both ends of the sheet-like elastic member 130 are movably connected to the side wall of the receiving compartment, the number of locking holes can be two; when only one end of the sheet-like elastic member 130 is movably connected to the side wall of the receiving compartment, the number of locking holes can be one. As a preferred embodiment, when the side wall of the receiving compartment is perpendicular to the bottom wall of the receiving compartment, the axial direction of the locking holes is perpendicular to the plane containing the bottom wall of the receiving compartment.
[0049] The end of the sheet-like elastic member 130 is located in the gap between the side of the locking pin 150 and the side wall of the receiving chamber. That is, the end of the sheet-like elastic member 130 can be inserted into the gap between the side of the pin and the side wall of the receiving chamber, so that the end of the sheet-like elastic member 130 can move within the gap.
[0050] It is worth mentioning that, since the position of the movable end of the sheet elastic member 130 usually changes when it is compressed, that is, it will move relative to the gap between the side of the latch 150 and the side wall of the receiving chamber, in order to prevent the end of the sheet elastic member 130 from falling out of the gap, the initial position of the end of the sheet elastic member 130 can extend beyond the gap by a portion, as a margin to prevent the end of the sheet elastic member 130 from falling out of the gap during its movement.
[0051] In the above implementation process, by using the locking pin 150 to press the end of the sheet elastic member 130 against the side wall of the receiving chamber, the movable connection of the end of the sheet elastic member 130 is achieved, which simplifies the movable connection method of the end of the sheet elastic member 130, and thus simplifies the structure of the adjustment mechanism 100.
[0052] In some alternative embodiments, the sheet-like elastic element 130 includes a spring sheet. Specifically, the spring sheet can be a metal spring sheet, etc., that does not undergo significant stretching or contraction, as mentioned above.
[0053] In the above implementation process, by using metal springs or other springs that do not undergo significant expansion and contraction as the specific sheet-like springs, the fatigue resistance is stronger, thereby ensuring that the adjustment mechanism 100 maintains a consistent reset force throughout its service life, and guaranteeing long-term adjustment accuracy and reliability.
[0054] Please continue to refer to Figure 2 and Figure 3 In some alternative embodiments, the sidewall of the receiving compartment is provided with a groove 1121. The projection of the sheet-like elastic member 130 on the sidewall along the direction of movement of the target adjustment member 120 is located within the groove 1121. That is, the groove 1121 can serve as a clearance space for the sheet-like elastic member 130.
[0055] In the above implementation process, as the sheet-like elastic member 130 is pushed against by the target adjusting member 120, the middle section of the sheet-like elastic member 130 usually moves towards the side wall of the receiving chamber. Therefore, in order to avoid the middle section of the sheet-like elastic member 130 being restricted by the side wall of the receiving chamber, a groove 1121 is provided on the side wall as a clearance space, thereby expanding the adjustable range of the adjusting mechanism 100.
[0056] Please continue to refer to Figure 2 and Figure 3 In some optional embodiments, the number of sheet-like elastic elements 130 is two or more. The arrangement direction of the two or more sheet-like elastic elements 130 intersects the plane containing the bottom wall of the receiving compartment. For example, the sheet-like elastic elements 130 are rectangular, with the long side of the rectangle parallel to the plane containing the bottom wall of the receiving compartment. Accordingly, the arrangement direction of the sheet-like elastic elements 130 can be parallel to the wide side of the rectangle. That is... Figure 2 The arrangement shown is vertical.
[0057] In the above implementation process, by setting at least two sheet-like elastic elements 130, more contact points are made between each sheet-like elastic element 130 and the target adjusting element 120, thereby ensuring that the direction of movement of the target adjusting element 120 is more controllable by applying elastic force to the sheet-like elastic elements 130. Ultimately, this further improves the reliability and adjustment accuracy of the adjusting mechanism 100.
[0058] Please continue to refer to Figure 2 and Figure 3In some optional embodiments, the adjustment mechanism 100 provided in this application further includes a second pushing member 160. The main body 110 is also provided with a second adjustment hole 1112. The second adjustment hole 1112 communicates with the receiving chamber. The second pushing member 160 is disposed in the second adjustment hole 1112 and is movable along the axial direction of the second adjustment hole 1112. The second pushing member 160 is configured to push the target adjustment member 120 to move along the bottom wall of the receiving chamber and compress the sheet-like elastic member 130, or release the target adjustment member 120. The axial direction of the first adjustment hole 1111 intersects the axial direction of the second adjustment hole 1112.
[0059] The structure of the second adjusting hole 1112 can be similar to that of the first adjusting hole 1111, and the structure of the second pushing member 160 can also be similar to that of the first pushing member 140.
[0060] In the above implementation process, by setting a second pusher 160 and a second adjustment hole 1112 on the basis of setting a first pusher 140 and a first adjustment hole 1111, the target adjustment member 120 is adjustable in two directions within the plane of the bottom wall of the receiving compartment. This expands the adjustable range of the adjustment mechanism 100 and further improves the applicability and convenience of the adjustment mechanism 100.
[0061] Please continue to refer to Figure 2 and Figure 3 In some optional embodiments, the axial direction of the first adjusting hole 1111 is perpendicular to the axial direction of the second adjusting hole 1112. As a preferred embodiment, the second adjusting hole 1112 is disposed on the base of the main body 110 on the side away from the sheet-like elastic member 130, and the elastic force of the sheet-like elastic member 130 can be parallel to the bisector of the angle between the axial direction of the second adjusting hole 1112 and the axial direction of the second adjusting hole 1112.
[0062] In the above implementation process, the design of the axis of the first adjustment hole 1111 being perpendicular to the axis of the second adjustment hole 1112 allows for a more intuitive determination of whether to adjust the target adjustment member 120 individually or by using the first push member 140 and the second push member 160 in conjunction with the target adjustment member 120, based on the position of the target adjustment member 120 relative to the main body 110. This further improves the applicability and convenience of the adjustment mechanism 100.
[0063] In some alternative embodiments, the inner wall of the first adjusting hole 1111 is provided with a first internal thread, and the first pusher 140 is provided with an external thread adapted to the first internal thread; and / or the inner wall of the second adjusting hole 1112 is provided with a second internal thread, and the second pusher 160 is provided with an external thread adapted to the second internal thread.
[0064] In the above-described process, when adjusting the target adjusting member 120 via the adjusting mechanism 100, the first pushing member 140 and / or the second pushing member 160 can be rotated to move them forward or backward, converting a large amount of operation into a small amount of displacement for the first pushing member 140 and / or the second pushing member 160, thereby improving the adjustment accuracy of the adjusting mechanism 100. Furthermore, through the adaptation between the internal and external threads, the first pushing member 140 and / or the second pushing member 160 can achieve self-locking in any position.
[0065] Please refer to Figure 2 and Figure 4 , Figure 4 It is along Figure 1 The second type of horizontal plane cut cross-sectional view. In some alternative embodiments, the target adjustment member 120 includes a body 121 and a connecting portion 122. The connecting portion 122 extends outward from the side of the body 121 near the sheet-like elastic member 130 in a direction toward the sheet-like elastic member 130.
[0066] A waist hole 1221 is provided on the connecting part 122. The axial direction of the waist hole 1221 is perpendicular to the plane of the bottom wall of the receiving compartment. When the sheet-like elastic member 130 does not deform, the guiding direction of the waist hole 1221 is parallel to the angle bisector of the angle between the axial direction of the first adjusting hole 1111 and the axial direction of the second adjusting hole 1112. In other words, the guiding direction of the waist hole 1221 can be parallel to the direction of the elastic force applied by the sheet-like elastic member 130 to the target adjusting member 120.
[0067] The adjustment mechanism 100 provided in this embodiment further includes a connecting pin 170. The side wall of the receiving compartment is provided with a connecting pin 170 hole whose axial direction is parallel to the axial direction of the waist hole 1221. The connecting pin 170 is located between the waist hole 1221 and the connecting pin 170 hole.
[0068] In the above implementation process, the waist hole 1221 on the target adjustment component 120 is connected to the side wall of the receiving chamber, which restricts the controllable tilting, rotation or jamming when the target adjustment component 120 is pushed, thereby ensuring that the adjustment process is carried out as expected, which also improves the reliability of the adjustment mechanism 100.
[0069] Please continue to refer to Figure 2 and Figure 3In some alternative embodiments, the main body 110 includes a seat 111 and a side cover 112. The seat 111 includes a bottom wall for receiving a compartment. The two ends of a sheet-like elastic member 130 are connected to the inner wall of the side cover 112. The side cover 112 is detachably connected to the seat 111.
[0070] For example, the side cover 112 can function as a drawer, and can be pulled out to be connected or separated from the seat 111.
[0071] In the above implementation process, the detachable connection between the base 111 and the side cover 112 allows the receiving compartment to be opened, thereby allowing the target adjustment component 120 inside the receiving compartment to be replaced when the receiving compartment is open. For example, when the target adjustment component 120 is specifically an optical lens and a lens mount, optical lenses with different parameters can be replaced as needed.
[0072] Based on the same concept, this application provides an optical processing head, including the adjustment mechanism 100 described above. The target adjustment element 120 of the adjustment mechanism 100 includes an optical lens assembly. Specifically, the optical lens assembly may include a lens mount and an optical lens.
