Description

Technical Field

[0001] This invention relates to the field of industrial scanning and imaging technology, and in particular to a three-way translation stage for controlling lens zoom. Background Technology

[0002] In the field of industrial scanning and imaging technology, the common operating procedure for photographing multiple objects distributed in a plane is to photograph each object one by one, with the camera lens focus manually adjusted before each shot. However, under the current technological framework, the photographing of objects relies primarily on manual labor, with focus adjustments performed simultaneously during the process. This traditional method has significant drawbacks: extremely low shooting efficiency, a lengthy and time-consuming process, and consequently, a substantial increase in shooting costs. Therefore, given this existing technological situation, there is an urgent need to develop an innovative solution to overcome these limitations. Summary of the Invention

[0003] The purpose of this invention is to overcome the problems of low shooting efficiency and long shooting process when shooting multiple objects distributed in a plane in the prior art, and to provide a three-way translation worktable for controlling lens zoom.

[0004] This invention provides a three-way translation stage for controlling lens zoom, comprising: A base plate, on which two columns are provided; A first linear guide rail is mounted on the base plate and located between the two columns. A carrying plate is mounted on the first linear guide rail and can move along the first linear guide rail. The second linear guide rail has its two ends connected to the tops of the two columns respectively, and the axis of the second linear guide rail is perpendicular to the axis of the first linear guide rail. The third linear guide rail is mounted on the second linear guide rail via a bracket. The axial direction of the third linear guide rail is parallel to the axial direction of the column. The bracket can drive the third linear guide rail to move along the second linear guide rail. A camera mount is mounted on the third linear guide rail and can move along the third linear guide rail. The camera mount is used to fix a camera. The camera mount includes a motor, which can drive the zoom ring of the camera lens to rotate through a transmission mechanism.

[0005] This invention provides a three-way translation stage for controlling lens zoom. The base plate serves as a fundamental support component, fixing two columns and a first linear guide rail, providing stable support for the entire stage. The first linear guide rail drives the worktable to move horizontally along a straight line. The worktable is used to place or fix the object to be scanned and photographed. The two columns are vertically mounted on the base plate, supporting the second linear guide rail. The second linear guide rail drives the support base to move horizontally along a straight line. Since the third linear guide rail is mounted on the second linear guide rail via the support base, the support base can further drive the third linear guide rail to move axially along the second linear guide rail. The third linear guide rail drives the camera mount to move vertically. Because the axial direction of the second linear guide rail is perpendicular to the axial direction of the first linear guide rail, the movement directions of the worktable, the third linear guide rail, and the camera mount are mutually perpendicular in three-dimensional space, achieving a three-way translation function between the worktable and the camera. The camera mount is used to mount the camera. The motor is connected to the zoom ring of the camera through the transmission mechanism. By driving the zoom ring to rotate, the focal length of the lens can be automatically controlled.

[0006] This invention provides a three-way translation stage for controlling lens zoom. Through the coordinated movement of the first, second, and third linear guide rails, the relative position of the object on the carrier plate and the camera can be flexibly adjusted, enabling precise positioning and shooting of objects at different locations. Simultaneously, by controlling the zoom ring of the lens via a motor, the focal length can be quickly adjusted according to shooting requirements, ensuring the clarity of the captured image. This design allows the stage to perform batch scanning and photography, greatly improving shooting efficiency and effectively shortening shooting time.

[0007] Preferably, the camera mount includes a base plate, a first fixing plate, and a second fixing plate. The first fixing plate and the second fixing plate are arranged side by side on the base plate. The first fixing plate and the second fixing plate are used to mount the lens, and the motor is connected to the second fixing plate. In this design, the base plate is used to fix the first fixing plate and the second fixing plate. The first fixing plate and the second fixing plate cooperate with each other to provide a mounting position for the lens, ensuring that the lens can be stably mounted and fixed. The motor is connected to the second fixing plate to ensure that the motor and the lens maintain a relative positional relationship.

[0008] The transmission mechanism can be a gear drive, belt drive, or worm gear drive.

[0009] Preferably, the transmission mechanism includes a first pulley, a second pulley, and a belt. The first pulley is fitted onto the zoom ring of the lens, the second pulley is connected to the motor shaft, and the belt connects the first pulley and the second pulley. The second pulley can drive the first pulley to rotate via the belt, thereby driving the zoom ring to rotate. In this configuration, the motor drives the second pulley to rotate, and the belt acts as a transmission between the first and second pulleys, thus driving the first pulley to rotate. Since the first pulley is fitted onto the zoom ring, its rotation can drive the zoom ring to rotate. Ultimately, by driving the second pulley with the motor, and then driving the first pulley via the belt, the rotation of the zoom ring is controlled, achieving the purpose of adjusting the lens focal length.

[0010] Preferably, the system further includes a third fixing plate and a fourth fixing plate, which are connected to the base plate. Both the third and fourth fixing plates have U-shaped cross-sections, and their openings are arranged opposite to each other to form a cavity. The first pulley is located within this cavity. In this design, the cavity formed by the third and fourth fixing plates completely encloses the first pulley, leaving only one opening for the belt to pass through, thus reducing the entry of external dust and debris into the cavity. Simultaneously, the third and fourth fixing plates provide some protection for the first pulley, reducing the risk of damage from accidental collisions, scratches, and other external forces, ensuring the stable and reliable operation of the first pulley.

[0011] Preferably, the motor is connected to the second fixing plate via a bracket plate. The bracket plate has an L-shaped structure, comprising a first flat plate and a second flat plate. The first flat plate of the bracket plate is connected to the second fixing plate, and the second flat plate of the bracket plate is connected to the motor. In this design, the bracket plate reliably fixes the motor to the second fixing plate, ensuring a stable connection between the motor and the second fixing plate.

[0012] Preferably, the motor's mounting position can be adjusted in a direction away from or near the base plate. Since the motor and the first pulley are connected via a belt, designing the motor to be adjustable in this direction offers significant advantages. In practical applications, the tension and length of belts of different specifications or after a period of use may change. By adjusting the motor's position, it is possible to flexibly adapt to belts in various states. When installing the belt, the motor's position can be adjusted to ensure the belt is in an ideal taut state. This taut state effectively reduces belt slippage during transmission, lowers energy loss, and improves transmission efficiency, thereby ensuring better transmission performance for the entire transmission system.

[0013] The motor can be moved and fixed in one of the following ways: the motor is fixed on a slider, the support plate has a corresponding groove, and the slider can drive the motor to move along the groove; or the motor can be fixed on a transition plate, the transition plate has an elongated hole, the transition plate can slide along the second plate of the support plate, and is fixed by bolts passing through the elongated hole and the second plate of the support plate.

[0014] Preferably, the second plate of the support plate is provided with a first strip-shaped hole, and a transition plate is provided between the second plate of the support plate and the motor. The transition plate is provided with a through hole and a second strip-shaped hole. The rotating shaft of the motor passes through the first strip-shaped hole and the through hole. The motor is fixedly connected to the transition plate, and the transition plate is connected to the second plate of the support plate by bolts through the second strip-shaped hole.

[0015] In this design, the length directions of both the first and second strip-shaped holes are parallel to the line connecting the motor and the base plate. Since the motor is fixedly connected to the transition plate, there is no relative movement between the motor's shaft and the through hole. The first strip-shaped hole provides a certain amount of space for the motor's shaft to move, ensuring it doesn't obstruct movement when adjustment is needed. The second strip-shaped hole allows for a certain range of adjustment in the relative position between the transition plate and the second flat plate of the support plate. This adjustment allows for changes in the relative position of the motor and the support plate, ultimately enabling the motor's mounting position to be adjusted towards or away from the base plate.

[0016] Preferably, the base plate is further provided with two guide rails, which are located on both sides of the first linear guide rail and are parallel to the axis of the first linear guide rail. The bottom of the carrying plate is provided with two support legs, which are connected to the two guide rails by sliders. The sliders can move along the corresponding guide rails.

[0017] In this design, the carrying plate is supported not only by the first linear guide rail but also by two legs supported by sliders on the two guide rails. This multi-support structure effectively increases the number of support points for the carrying plate during movement, distributing the weight of the carrying plate and the object it carries, thereby improving the stability of the carrying plate during movement.

[0018] Preferably, a first cable chain is provided on one side of the second linear guide rail. The first cable chain is installed in a first cable chain groove, which is arranged side by side with the second linear guide rail. One end of the first cable chain is connected to the bracket seat through a first connecting plate. The first cable chain is used to install the power cord of the third linear guide rail.

[0019] In this design, the first cable chain groove is used to accommodate and place the first cable chain. One end of the first cable chain is connected to the bracket seat via the first connecting plate to ensure that this end of the first cable chain can move together with the bracket seat. By installing the power cord of the third linear guide rail inside the first cable chain, the connection of the power cord can be made neater and more orderly, avoiding tangled situations; on the other hand, it can prevent the power cord from being interfered with or damaged during the movement of the third linear guide rail, thereby ensuring that the third linear guide rail can move normally and smoothly.

[0020] Preferably, a second cable chain is provided on one side of the third linear guide rail. The second cable chain is installed in a second cable chain groove, which is arranged side by side with the third linear guide rail. One end of the second cable chain is connected to the camera mounting base through a second connecting plate. The second cable chain is used to install the power cords of the camera and the motor.

[0021] In this design, the second cable chain groove is used to accommodate and place the second cable chain. One end of the second cable chain is connected to the camera mount via the second connecting plate, ensuring that this end of the second cable chain can move along with the camera mount. By installing the motor's power cable inside the second cable chain, on the one hand, the connection of the motor's power cable can be made neater and more orderly, avoiding tangled situations; on the other hand, it can prevent the motor's power cable from being interfered with or damaged during the movement of the camera mount, thereby ensuring that the camera mount can move normally and smoothly.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a three-way translation stage for controlling lens zoom. Through the coordinated movement of the first, second, and third linear guide rails, the relative position of the object on the carrier plate and the camera can be flexibly adjusted, enabling precise positioning and shooting of objects at different locations. Simultaneously, by controlling the zoom ring of the lens via a motor, the focal length can be quickly adjusted according to shooting requirements, ensuring the clarity of the captured image. This design allows the stage to perform batch scanning and photography, greatly improving shooting efficiency and effectively shortening shooting time. Attached Figure Description

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0040] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0041] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0042] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0043] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0044] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
