Description

Technical Field

[0001] The present invention relates to the field of automated micromachining equipment, in particular to an automatic needle calcining instrument. Background Art

[0002] Glass capillaries are widely used in various micromanipulations, such as sperm injection and oocyte manipulation, during in vitro fertilization (IVF) nuclear transfer. These procedures require specific shapes and dimensions to ensure precision and efficiency. To meet these requirements, glass capillaries often undergo a calcination process.

[0003] When using the capillary glass tube calcining processing equipment, the capillary glass tube and the heating bead need to be moved so that the relative position of the capillary glass tube and the heating bead is adjusted to a preset position. During the adjustment process, there is only one set of microscope light paths. The alignment of the capillary glass tube and the heating bead in the axial direction of the light path is based on subjective judgment of whether the images of the capillary glass tube and the heating bead are clear. This method has low accuracy and easily leads to uncontrollable bending angles. The time from the start of heating to the end of bending the capillary glass tube is very short. During bending, the worker observes the bending angle under a microscope and stops heating based on experience. The final forming angle mainly depends on the worker's experience and reaction speed. The angle repeatability is poor and prone to failure. Each bending process relies on the microscope system, which is very harmful to the operator's eyes. The operator needs to rest after operating for a period of time, and the production efficiency is low. Summary of the Invention

[0047] See also Figure 9 The needle holding module 60 is used to clamp the sample needle 66 (capillary glass tube) and adjust the position and angle of the sample needle 66. The needle holding module 60 includes a bracket 61, a first movable structure 62, a second movable structure 63, a rotary drive structure 64 and a needle holder 65. The bracket 61 is fixed to the base plate 10, and the first movable structure 62, the second movable structure 63, the rotary drive structure 64 and the needle holder 65 are installed on the bracket 61 so that the sample needle 66 can be suspended in the air. The bracket 61 is in an inverted U shape, and the light source module 50 is installed at the bottom of the bracket 61 so that the light of the light source module 50 directly illuminates the end of the sample needle 66. The first movable structure 62 is a linear module or a cylinder. The first movable structure 62 is installed on the bracket 61. The first movable structure 62 drives the second movable structure 63, the rotary drive structure 64 and the needle holder 65 to move in the second direction. The second movable structure 63 is mounted at the output end of the first movable structure 62. The second movable structure 63 is arranged vertically and drives the rotary drive structure 64 and the needle holder 65 to move in the third (vertical) direction. The rotary drive structure 64 is mounted at the output end of the second movable structure 63 and is in driving connection with the needle holder 65, driving the needle holder 65 to rotate. The rotary drive structure 64 and the needle holder 65 are driven by any of a gear meshing transmission, pulley rotation, or worm gear transmission. A sample needle 66 is mounted in the needle holder 65.

[0048] When using the automatic needle calcining instrument, the instrument is powered on and the entire device is reset, and the needle holding module 60 moves to the working position for loading the sample needle 66 (capillary glass tube).

[0049] During the sample needle 66 loading process, the operator inserts the sample needle 66 into the needle holder 65, then inserts the needle holder 65 into the circular hole of the needle holder's rotating shaft. The machining tolerances for the needle holder shaft diameter and the inner diameter of the circular hole are a clearance fit, and the combined length of the sample needle 66 and needle holder 65 should be within the tooling scale. The needle holder's rotating shaft has four ball plungers that correspond to two annular positioning grooves on the needle holder 65. When the needle holder 65 is loaded, the sample needle 66 is considered loaded when the four ball plungers engage the annular grooves.

[0050] Then, click on the software to start bending, and the instrument will automatically perform the needle tip automatic alignment, heating bead automatic alignment, needle-heating bead relative position correction, and bending steps.

[0051] Specifically, the needle tip automatic alignment process begins. After clicking Start, the needle holding module 60 and the main viewing module 20 move to the preset coordinates, and the sample needle 66 appears in the field of view of the main viewing light path. First, based on the microscopic image, the second movable structure 63 gradually lifts the sample needle 66 until the needle tip enters the field of view. Then, based on a large amount of machine learning of needle tip shape data, the main viewing drive structure 24 dynamically adjusts the lens position of the main viewing objective lens 225 in the main viewing light path. After the needle tip image is clear, the direction of the needle tip bevel is determined. If the needle tip bevel is not facing the light source 52, the rotary drive structure 64 drives the sample needle 66 to rotate around the axis by a preset angle (in this embodiment, the preset angle is 5°), and automatically focuses again to determine the direction until the needle tip bevel faces the light source 52. After the needle tip is aligned, the coordinate A of the needle tip in the microscopic image is recorded. Then, the first movable structure 62 and the second movable structure 63 of the needle holding module 60 drive the sample needle 66 to retract in the second and third directions, respectively. In this embodiment, the retraction is 1.5 mm to leave space for the automatic alignment of the heating beads.

[0052] During the automatic alignment process for the heating beads, the first, second, and third heating drive mechanisms 41, 42, and 44 of the heating module 40 first drive the heating mechanism 45 to a preset position. The side view drive mechanism 31 then drives the side view image acquisition mechanism 33 to a preset position. This allows a clear image of the heating beads to be formed in the side view optical path. Based on the microscopic image, the third heating drive mechanism 44 of the heating module 40 is adjusted to ensure a clear image of the heating beads in the main view optical path. The coordinate B of the left tip of the heating bead in the microscopic image is recorded.

[0053] In the needle-heating bead relative position correction process, the theoretical position of the needle tip is first calculated based on coordinate B and the preset distance between the needle tip and the heating bead tip. Then, the distance between the needle tip and the theoretical position is calculated based on coordinate A, and the needle tip is moved to the theoretical position. After the movement is completed, the distance between the heating bead tip and the outer wall of the needle is measured based on the microscopic image of the main optical path, and the needle position is fine-tuned so that the distance between the two is close to the preset distance; the Z-axis position of the heating bead is fine-tuned based on the microscopic image of the side optical path.

[0054] During the bending process, the heating wire 454 is heated according to the preset acceleration curve and maximum power. The instrument recognizes the main optical path microscope image in real time, calculates the bending angle of the sample needle 66, and stops heating when the bending angle reaches the predetermined angle.

[0055] During the sample needle 66 unloading process, each moving part returns to zero point in sequence, and the operator removes the needle holder 65 from the needle holding shaft, and then removes the sample needle 66 from the needle holder 65 .

[0056] The main view driving structure 24 of the automatic needle calcining instrument of the present invention drives the main view image acquisition structure 22 to move in a first direction close to or away from the needle holding module 60 to adjust the distance between the main view image acquisition structure 22 and the tip of the sample needle 66 so that the main view image acquisition structure 22 acquires the main view image of the tip of the sample needle 66; the first heating driving structure 41, the second heating driving structure 42 and the third heating driving structure 44 of the heating module 40 adjust the position of the heating structure 45 so that the distance between the heating structure 45 and the tip of the sample needle 66 reaches a preset value, and the heating structure 45 heats the tip of the sample needle 66 so that the tip of the sample needle 66 bends; the side view driving structure 31 of the side view module 30 drives the side view image acquisition structure 33 to move perpendicular to the first The side image acquisition structure 33 captures an image of the heating structure 45, and the heating module 40 adjusts the position of the heating structure 45 based on the image of the heating structure 45. The first movable structure 62 and the second movable structure 63 of the needle holding module 60 adjust the position of the sample needle 66, and the rotary drive structure 64 rotates the sample needle 66 so that the bevel at the tip of the sample needle 66 is at a preset position. This design ensures high precision and controllable bending angle during heating of the tip of the sample needle 66. The production process utilizes image recognition, eliminating the need for manual observation and achieving high production efficiency. All capillary glass tube calcination steps can be completed quickly and accurately, significantly lowering the technical threshold for capillary glass tube micromachining and improving product yield and production efficiency. Compared to manual needle bending machines, which require extensive operator training and practice, the automated bending machine requires virtually no operator expertise, reducing labor costs for processing companies and biological laboratories and expanding the application range of capillary glass tube processing. Key parameters during the processing are editable, measurable, and controllable, facilitating the customized development of capillary glass tube products.

[0057] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patented invention. It should be noted that those skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention. These variations and improvements are equivalent modifications and improvements to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
