Description

Technical Field

[0001] This utility model relates to the field of optical system technology, and in particular to a glass slide rotating frame. Background Technology

[0002] Time-lapse imaging is a technique that records the changes of an object over time by continuously capturing images at set time intervals, and the slide rotation mechanism is a crucial component in this process. However, existing slide rotation mechanisms suffer from the drawback that the slide continues to rotate at a certain angle due to inertia after a power outage or when the motor stops. Although the rotation angle is small, this rotation affects the accuracy of the camera and the image. Furthermore, when rotating the slide again, the angle shifts, making it difficult to accurately control the rotation precision. Utility Model Content

[0003] This invention provides a glass slide rotation holder to overcome the shortcomings of the prior art, solve the problem of the influence of rotational inertia on precise control, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A slide rotation holder includes a base with a mounting groove at its upper end. A mounting plate is fixed to the mounting groove by screws. A DC servo motor is mounted on the mounting plate. A bearing is fitted onto the output shaft of the DC servo motor, and the outer ring of the bearing is fixed to the mounting plate. A drive gear is connected to the output shaft of the DC servo motor, and the drive gear has multiple alignment holes. An inductive switch is mounted on the mounting plate, and the drive gear has alignment holes. In the event of a power failure, the inductive switch and alignment holes enable automatic repositioning to improve control accuracy. Furthermore, to further enhance control accuracy, an absolute encoder is connected to the output shaft of the DC servo motor to provide feedback on the rotation angle of the drive gear, thereby improving rotation control precision.

[0006] The drive gear meshes with the driven gear, and the driven gear is connected and fixed to the end tube. The inner tube is located inside the end tube, and the outer diameter of the inner tube is larger than that of the end tube. The inner tube passes through the lower end of the base and is fitted with a pair of driven bearings. The outer ring of the driven bearings is fixed inside the lower end of the base. The use of two driven bearings can improve the flexibility of the inner tube rotation and ensure that the glass slide and the inner tube have a high degree of overlap when rotating.

[0007] The inner tube has an annular groove formed on its inner circumference at the other end. A glass slide is provided on the inner side of the annular groove. An inner tube is inserted through the annular groove. A fixing ring is formed on the outer side of the inner tube. The fixing ring is installed on the end of the inner tube by screws. This fixing method is convenient for fixing and the fixed glass slide is located inside the inner tube, thus avoiding the glass slide from being exposed and easily damaged.

[0008] Furthermore, a spacer ring is provided on the outer circumference of the inner tube, and the driven bearings are located at both ends of the spacer ring. The spacer ring separates the two driven bearings to facilitate assembly and assembly operations.

[0009] Furthermore, to promptly lock the state of the inner tube after a power outage, a pair of middle blocks are installed on the base. These middle blocks are distributed on the upper and lower sides of the inner tube, with connecting pins threaded to both ends. The outer ends of the connecting pins are fitted with end caps, and the inner ends are fitted with springs. Clamping plates are fitted onto the connecting pins on the same side. The outer ends of the springs contact the inner walls of the clamping plates, and the inner ends of the springs contact the outer ends of the middle blocks. The inner end faces of the clamping plates are tightly pressed against the outer circumference of the inner tube. A boss is formed on the inner wall of the clamping plates, and a top wheel is tangent to the outer wall of the boss. A top plate rotates on the top wheel, and a hinge screw passes through the top plate. The hinge screw is threaded to the base. On the body, a horizontal hole is opened at the outer end of the top plate, and an actuating rod passes through the horizontal hole. A concave part is welded to the outer end of the actuating rod. A waist-shaped hole is opened in the vertical section of the concave part, and a limiting screw passes through the waist-shaped hole. The limiting screw is connected to the base body by screws. A pair of protrusions are welded on the horizontal section of the concave part. A strong magnetic rod is threaded onto the protrusions. A coil is sleeved on the strong magnetic rod. A concave insulating plate is placed on the coil. The concave insulating plate is installed on the base body by screws. The coil here can be powered by an independent power supply system. When the system loses power, the system can start to supply power to clamp the inner tube through two clamps to prevent the inner tube from continuing to rotate. Alternatively, a downward compression spring can be set on the concave part. When the inner tube rotates, the downward compression spring is in a compressed state. At this time, the coil is powered by the system and continuously generates a constant magnetic field. If a power failure occurs, the disappearance of the current in the coil will cause the concave part to move downward under the action of the downward compression spring, and the clamps will constrain and limit the inner tube.

[0010] Furthermore, the inner end face of the clamping plate is provided with a concave arc groove, which is coaxial with the inner tube. This design can increase the contact area between the clamping plate and the outer periphery of the inner tube, thereby improving the locking effect.

[0011] Furthermore, the outer side and outer side of the boss are both concave arc-shaped structures. When the top plate rotates, this arc-shaped surface improves its flexibility during rotation.

[0012] Furthermore, a guide is fitted onto the vertical section of the concave part, and a guide groove is provided on the outer side of the guide. The vertical section of the concave part is located in the guide groove. The stability of the lifting and moving of the concave part is improved by the provided guide and guide groove.

[0013] Furthermore, in order to limit the rotation of the top plate, a constraint pin is contacted on the upper side of the top plate. The constraint pin is located on the base and inside the hinge screw to prevent the top plate from rotating excessively.

[0014] The advantages of the above technical solution are:

[0015] This invention can perform a locking operation in a timely manner after power failure to prevent excessive and uncontrollable rotation of the glass slide. In addition, if excessive rotation occurs, it can perform a return operation after power is restored to ensure control accuracy. Attached Figure Description

[0022] Figure 6 The three-dimensional structure of the constraint mechanism is shown. Figure 2 . Detailed Implementation

[0023] like Figures 1-4 As shown, a glass slide rotating holder includes a base 1 with a mounting groove at the upper end. A mounting plate 10 is fixed to the mounting groove by screws. A DC servo motor 2 is mounted on the mounting plate 10. A bearing is sleeved on the output shaft of the DC servo motor 2, and the outer ring of the bearing is fixed to the mounting plate 10. A drive gear 3 is connected to the output shaft of the DC servo motor 2. The drive gear 3 has multiple alignment holes 31. An inductive switch 30 is mounted on the mounting plate 10.

[0024] A drive gear 3 meshes with a driven gear 32. An end tube 33 is fixedly connected to the driven gear 32. An inner tube 34 extends from the inner end of the end tube 33, with an outer diameter larger than that of the end tube 33. The inner tube 34 passes through the lower end of the base 1. A pair of driven bearings 40 are fitted onto the inner tube 34, with their outer rings fixed to the interior of the lower end of the base 1. A spacer ring 35 is provided on the outer circumference of the inner tube 34, with the driven bearings 40 located at both ends of the spacer ring 35. An annular groove is formed on the inner circumference of the other end of the inner tube 34. A glass slide 37 is provided on the inner end of the annular groove, and an inner tube 38 passes through the annular groove. A fixing ring 39 is formed on the outer end of the inner tube 38, and the fixing ring 39 is installed on the end of the inner tube 34 by screws.

[0025] In this embodiment, the DC servo motor 2 drives the drive gear 3 to rotate, and the rotation angle of the drive gear is measured and fed back in a timely manner by an absolute encoder. As the drive gear 3 rotates, it will drive the driven gear 32 to rotate, and the driven gear 32 will drive the inner tube 34 to rotate, thereby achieving the purpose of adjusting the rotation angle of the glass slide 37.

[0026] If the DC servo motor 2 loses power, the driven gear 32 will rotate at a certain angle due to its initial velocity. After power is restored, the DC servo motor 2 will start and drive the drive gear 3 to rotate. During this process, when the induction switch 30 and the alignment hole 31 are aligned, the automatic repositioning operation of the glass slide 37 is completed.

[0027] In some embodiments, such as Figures 5-6As shown, a pair of middle blocks 5 are installed on the base 1, distributed on the upper and lower sides of the inner tube 34. The two ends of the middle blocks 5 are connected by connecting pins 50 through threads. The outer end of the connecting pin 50 is provided with an end cap, and the inner end of the connecting pin 50 is fitted with a spring 51. A clamping plate 52 is fitted on the connecting pin 50 on the same side. The outer end of the spring 51 contacts the inner wall of the clamping plate 52, and the inner end of the spring 51 contacts the outer end of the middle block 5. The inner end face of the clamping plate 52 is in close contact with the outer periphery of the inner tube 34. The inner end face of the clamping plate 52 is provided with a concave arc groove, which is coaxial with the inner tube 34. The inner wall of the clamping plate 52 is formed with a boss 53, and the outer side and outer side of the boss 53 are both concave. The structure is arc-shaped. A top wheel 54 is tangent to the outer wall of the boss 53. A top plate 57 is rotatably mounted on the top wheel 54. A hinge screw 56 passes through the top plate 57 and is threaded to the base 1. A horizontal hole 58 is opened at the outer end of the top plate 57. An actuating rod 62 passes through the horizontal hole 58. A concave part 59 is welded to the outer end of the actuating rod 62. A waist-shaped hole 60 is opened in the vertical section of the concave part 59. A limiting screw 61 passes through the waist-shaped hole 60 and is screwed to the base 1. A guide 73 is sleeved on the vertical section of the concave part 59. A guide groove is opened on the outer side of the guide 73, and the vertical section of the concave part 59 is located in the guide groove. A pair of protrusions 63 are welded to the horizontal section of the concave part 59. A strong magnetic rod 64 is threaded onto the protrusion 63. A coil 66 is sleeved on the strong magnetic rod 64. A concave insulating plate 65 is provided on the coil 66. The concave insulating plate 65 is installed on the base 1 by screws. A constraint pin 7 is in contact with the upper side of the top plate 57. The constraint pin 7 is provided on the base 1.

[0028] In some embodiments, the coil 66 is powered by a battery, which can supply power to the coil 66 in the event of a power outage.

[0029] In this embodiment, if a power failure occurs, the system stops supplying power, and the battery supplies power to the coil 66. At this time, the coil 66 generates a stable magnetic field, which causes the strong magnetic rod 64 to move outward. As the strong magnetic rod 64 moves outward, the concave part 59 moves downward. The downward movement of the concave part 59 causes the actuating rod 62 to act on the transverse hole 58, which causes the outer end of the top plate 57 to rotate downward and the inner end to rotate upward. During the rotation, the top wheel 54 at the inner end acts on the outer side of the boss 53, which causes the clamping plate 52 to move towards the periphery of the inner tube 34, thereby locking the inner tube 34 and preventing the inner tube 34 from continuing to rotate.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
