Description

Technical Field

[0001] This invention belongs to the field of freeze-dried microsphere technology, specifically relating to an optical lens holder for a freeze-dried microsphere preparation and detection device. Background Technology

[0002] The production of freeze-dried microspheres involves mixing bioactive substances or drugs with polymer materials to form microspheres, freezing them, and then heating them under vacuum to sublimate the water to obtain the product. However, the size of microspheres prepared manually is uneven, which limits large-scale production. Therefore, freeze-dried microsphere preparation equipment has emerged, which greatly reduces the labor intensity of manual production and improves production efficiency and product quality.

[0003] Before testing, the freeze-dried microsphere preparation device needs to set up optical lenses between the camera and the light source according to the testing requirements. The optical lenses are used to improve the shooting accuracy of the camera. Since the camera and the optical lens need to be precisely matched, it is necessary to adjust the relative angle between the optical lens and the camera. The optical lens is generally mounted on an optical lens bracket. Existing optical lens brackets require multiple adjustment mechanisms to achieve full-range angle adjustment when adjusting the angle of the optical lens, which is cumbersome. Moreover, after the angle is adjusted, a locking mechanism is required to lock it, which greatly increases the complexity of the optical bracket.

[0004] Therefore, an optical lens holder for a detection device for the preparation of freeze-dried microspheres is proposed. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Reference Figure 1 , 2 and Figure 7This invention provides an optical lens holder for a freeze-dried microsphere preparation and detection device, comprising a lens holder body 1. The lens holder body 1 includes a base 11, a side plate 12 and a guide post 13 disposed on the top of the base 11. The side plate 12 is located on one side of the guide post 13. A servo motor 14 is disposed on the top of the side plate 12. A lead screw 15 is fixedly connected to the output end of the servo motor 14 through one side. A moving stage 16 is fixedly connected to the screw nut seat on the lead screw 15. A guide platform 17 is sleeved on the outer side wall of the guide post 13. Both the guide post 13 and the side plate 12 are perpendicular to the base 11. 1. The guide column 13 passes through the guide table 17, the moving table 16 and the side plate 12 are slidably connected, the side plate 12 has an L-shaped structure, and the bottom end of the lead screw 15 is rotatably connected to the base 11. Under the vertical guidance of the guide column 13 and the side plate 12, the moving table 16 and the guide table 17 can move in the vertical direction, ensuring the stability of the height adjustment of the moving table 16 and the guide table 17. The stability of the rotation of the lead screw 15 can be ensured through the base 11. A fixing ring 18 is provided between the moving table 16 and the guide table 17, and a lens adjustment table 19 is provided on the inner side of the fixing ring 18. A lens slot 191 is provided at the center of one side outer wall of the lens adjustment platform 19, and a lens retaining ring 192 is provided on the outer side of one side outer wall of the lens adjustment platform 19 near the lens slot 191. A through hole is provided at the center of one side outer wall of the lens adjustment platform 19. The outer diameter of the lens retaining ring 192 is larger than the outer diameter of the lens slot 191. Through the size difference between the lens retaining ring 192 and the lens slot 191, the lens retaining ring 192 can cover the lens slot 191, thereby limiting the optical lens embedded in the lens slot 191 and ensuring that the optical lens is installed stably and securely. A lens deflection active component 2, a lens deflection driven component 3, a lens tilt active component 4, and a lens tilt driven component 5 are provided between the fixed ring 18 and the lens adjustment platform 19. The lens deflection active component 2, the lens deflection driven component 3, the lens tilt active component 4, and the lens tilt driven component 5 are arranged sequentially below, to the left, above, and to the right of the lens adjustment platform 19. In order to test the prepared freeze-dried microspheres and adjust the position of the optical angle according to the requirements, in this embodiment, the suitable optical lens is first placed into the lens slot 191 opened on the lens adjustment stage 19, and the lens retainer 192 is covered on one side of the optical lens and fixed. After the installation of the optical lens is completed, the angle of the optical lens is adjusted according to the required angle. The horizontal deflection angle and the vertical tilt angle of the optical lens are adjusted by the lens deflection active component 2, the lens deflection driven component 3, the lens tilt active component 4 and the lens tilt driven component 5, respectively.

[0021] Reference Figure 2-4The lens deflection active assembly 2 includes an active lower rotating rod 21 that rotates at the bottom of the inner wall of the fixed ring 18. A turbine 22 is provided on the outer wall of the active lower rotating rod 21, and a sliding cover 23 is provided at the top of the active lower rotating rod 21. A sliding groove 24 is provided at the top of the sliding cover 23. Both the sliding cover 23 and the sliding groove 24 are arc-shaped structures with the same axis, which allows the sliding block 25 inside the sliding groove 24 to perform circular motion, thereby realizing the vertical tilt angle adjustment of the lens adjustment stage 19. The slide groove 24 has a sliding lower slide block 25 inside, the top of the lower slide block 25 is fixed to the bottom of the lens adjustment stage 19, the outer side wall of the fixing ring 18 is provided with a side bracket 26, the inner side wall of the side bracket 26 is rotatably connected with a worm gear 27, one end of the worm gear 27 is provided with a handle 28, the turbine gear 22 and the worm gear 27 are connected by a transmission, and the transmission between the turbine gear 22 and the worm gear 27 allows the worm gear 27 to rotate and pull the turbine gear 22 to rotate. The lens deflection driven assembly 3 includes an upper rotating rod 31 that rotates on the top of the inner wall of the fixed ring 18. An upper sliding cover 32 is provided at the bottom of the upper rotating rod 31. An upper sliding groove 33 is provided at the bottom of the upper sliding cover 32. Both the upper sliding cover 32 and the upper sliding groove 33 are arc-shaped structures and their axes are the same circle, which allows the upper slider 34 inside the upper sliding groove 33 to perform circular motion, thereby realizing the vertical tilt angle adjustment of the lens adjustment platform 19. The upper slider 34 is slidably connected inside the upper sliding groove 33, and the bottom of the upper slider 34 is fixedly connected to the top of the lens adjustment platform 19. To achieve adjustment of the horizontal deflection angle of the optical lens, in this embodiment, the handle 28 is first rotated, which pulls the worm gear 27 to rotate. As the worm gear 27 rotates, the transmission between the turbine 22 and the worm gear 27 allows the worm gear 27 to pull the turbine 22 to rotate. As the turbine 22 rotates, the turbine 22 pulls the active lower rotating rod 21 to rotate. With the connection between the lower cover 23 and the lower slider 25, the lens adjustment stage 19 rotates in the horizontal direction. Since the turbine 22 and the worm gear 27 have a self-locking capability, the lens adjustment stage 19 is fixed in position after it is deflected to the required angle, thus achieving the purpose of adjusting the horizontal deflection angle of the optical lens for better focusing. With the assistance of the lens deflection driven component 3, the stability of the horizontal deflection movement of the lens adjustment platform 19 is ensured. Specifically, when the lens adjustment platform 19 rotates horizontally, the lens adjustment platform 19 pulls the upper rotating rod 31 to rotate under the connection of the upper sliding cover 32 and the upper sliding block 34. The upper rotating rod 31 and the fixed ring 18 are rotatably connected. The symmetrical rotation structure ensures the stability of the horizontal deflection. Since the guiding direction of the lower slide groove 24 to the lower slide block 25 and the guiding direction of the upper slide groove 33 to the upper slide block 34 are perpendicular to the horizontal rotation direction of the lens adjustment stage 19, the lower slide block 25 and the upper slide block 34 will not be displaced when the lens adjustment stage 19 rotates horizontally, thus indirectly transmitting the horizontal rotation force.

[0022] Reference Figure 2 , Figure 5 and Figure 6 The lens tilt active assembly 4 includes a left sliding cover 41 located on the left side of the inner wall of the fixing ring 18. A left sliding groove 42 is formed on the outer wall of the left sliding cover 41 away from the fixing ring 18. Both the left sliding cover 41 and the left sliding groove 42 are arc-shaped structures with the same axis, which allows the left slider 43 inside the left sliding groove 42 to perform circular motion, thereby adjusting the horizontal tilt angle of the lens adjustment stage 19. The left slider 43 is slidably connected inside the left sliding groove 42, and the end of the left slider 43 away from the left sliding cover 41 rotates. A left-turning rod 45 is connected, one end of which is fixedly connected to the left side wall of the lens adjustment stage 19. A turbine 44 is provided on the outer side wall of the left-turning rod 45, and a side bracket 46 is provided on the outer side wall of the left slider 43. A worm gear 47 is rotatably connected to the inner side wall of the side bracket 46. The turbine 44 and the worm gear 47 are connected by a transmission. By utilizing the transmission between the turbine 44 and the worm gear 47, the worm gear 47 can pull the turbine 44 to rotate when it rotates. A handle 48 is provided at one end of the worm gear 47. The lens tilt follower assembly 5 includes a right sliding cover 51 located on the right side of the inner wall of the fixing ring 18. A right sliding groove 52 is provided on the outer wall of the right sliding cover 51 away from the fixing ring 18. Both the right sliding cover 51 and the right sliding groove 52 are arc-shaped structures with the same axis. A right slider 53 is slidably connected inside the right sliding groove 52. One end of the right slider 53 is rotatably connected to a right rotating rod 54. One end of the right rotating rod 54 is fixedly connected to the right side wall of the lens adjustment stage 19. To achieve vertical tilt adjustment of the optical lens, in this embodiment, the second handle 48 is first rotated. During the rotation, the second handle 48 pulls the second worm gear 47 to rotate. Utilizing the transmission between the second turbine 44 and the second worm gear 47, the rotation of the second worm gear 47 can pull the second turbine 44 to rotate. As the second turbine 44 rotates, it pulls the left rotating rod 45 to rotate. One end of the left rotating rod 45 pulls the lens adjustment platform 19 to rotate vertically. Since the second turbine 44 and the second worm gear 47 have a self-locking capability, the lens adjustment platform 19 is fixed in position after tilting to the required angle. This allows for the adjustment of the tilt angle of the optical lens installed inside the lens adjustment platform 19, enabling better focusing and improving the accuracy of freeze-dried microsphere detection. With the assistance of the lens tilt follower component 5, the vertical tilt movement of the lens adjustment platform 19 is kept stable. Specifically, when the lens adjustment platform 19 rotates vertically, the lens adjustment platform 19 pulls the right rotating rod 54 to rotate under the connection of the right sliding cover 51 and the right sliding block 53. The right rotating rod 54 and the fixed ring 18 are rotatably connected. The symmetrical rotation structure ensures the stability of vertical tilt. Since the guiding direction of the left slide rail 42 to the left slider 43 and the guiding direction of the right slide rail 52 to the right slider 53 are perpendicular to the vertical rotation direction of the lens adjustment stage 19, the left slider 43 and the right slider 53 will not be displaced when the lens adjustment stage 19 rotates vertically, thus playing the role of indirectly transmitting horizontal rotational force.

[0023] Reference Figure 1 The lens support body 1 is mounted on the freeze-dried microsphere detection body 6. A connecting rod 7 is provided on the vertical moving mechanism of the lens support body 1. A bracket 8 and a light source 9 are respectively provided on the horizontal moving mechanism of the connecting rod 7. The bracket 8 is located on one side of the light source 9, and the top of the bracket 8 is fixedly connected to the base 11. In order to detect the microsphere volume, volume accuracy, and spray efficiency of freeze-dried microspheres, a lens bracket body 1 is set up to provide a position for the installation of various devices and can be adaptively adjusted according to the needs of the usage scenario to meet the detection standards.

[0024] Working principle: First, rotate the handle 28. During rotation, the handle 28 pulls the worm gear 27. As the worm gear 27 rotates, the transmission between the worm wheel 22 and the worm gear 27 causes the worm gear 27 to pull the worm wheel 22. The worm wheel 22 then pulls the drive lower rotating rod 21. Through the connection between the lower cover 23 and the lower slider 25, the lens adjustment stage 19 rotates horizontally. Because the worm wheel 22 and the worm gear 27 have a self-locking capability, the lens adjustment stage 19 is fixed in position after it has deflected to the desired angle. Rotating the second handle 48 causes the second worm gear 47 to rotate. Utilizing the transmission between the second worm gear 47 and the second worm 44, the rotation of the second worm gear 47 can drive the second worm gear 44 to rotate. As the second worm gear 44 rotates, it drives the left rotating rod 45 to rotate. One end of the left rotating rod 45 drives the lens adjustment platform 19 to rotate vertically. Since the second worm gear 47 and the second worm gear 44 have a self-locking capability, the lens adjustment platform 19 is fixed in position after tilting to the required angle, thereby enabling the adjustment of the tilt angle of the optical lens mounted inside the lens adjustment platform 19.
