Description

Technical Field

[0001] This utility model relates to an automatic sealing machine for precision probes. Background Technology

[0002] The sealing of precision probe tubes involves squeezing the tube opening material inward after the needle shaft and spring are installed, forming a narrow opening that locks the spring and prevents the needle shaft from dislodging.

Sealing small batches of probes currently relies on manual labor, which is time-consuming and labor-intensive. Utility Model Content

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] For ease of subsequent description, before describing the specific structure of the probe automatic sealing machine, this application will first combine... Figure 2 A first direction, a second direction, and a third direction are defined. The first direction is the width direction of the automatic sealing machine when it is normally positioned, such as the X direction; the second direction is the length direction of the automatic sealing machine when it is normally positioned, such as the Y direction; and the third direction is the height direction of the automatic sealing machine when it is normally positioned, such as the Z direction.

[0022] See appendix Figure 1-2As shown in this embodiment, an automatic sealing machine for precision probes includes a sealing module 1, a servo module 3, and an alignment plate 2. The sealing module 1 is used to seal the needle tube 7. The servo module 3 is located below the sealing module 1, and the sealing module 1 can move in a third direction. The alignment plate 2 is used to fix the needle tube 7. The alignment plate 2 is connected to the servo module 3, and the servo module 3 can drive the alignment plate 2 to move in a first direction and a second direction. The servo module 3 realizes the automated positioning of the needle tube 7, enabling the sealing module 1 to accurately seal the needle tube 7. The automatic sealing machine has a simple structure and is designed for small-batch production needs of new probes (such as electronic testing and minimally invasive medical probes) in laboratories or enterprise R&D departments. It replaces manual sealing, solves the pain point that large equipment cannot adapt to small-batch operations, and improves R&D efficiency and sealing consistency.

[0023] In some embodiments, the end cap module 1 includes an end cap and a pressure sensor 12 disposed above the end cap. The pressure sensor 12 is a device for detecting and measuring pressure, playing a crucial role in a precision probe automatic sealing machine. In this technical solution, the pressure sensor 12 is disposed above the end cap 11 of the end cap module 1, primarily for monitoring pressure parameters during the sealing process. Real-time detection of the sealing pressure of the end cap 11 on the needle tube 7 ensures the consistency and stability of the packaging quality and provides accurate pressure data to the servo module 3, enabling precise control of the automated packaging process. Pressure parameter monitoring prevents damage to the needle tube 7 or poor sealing caused by excessive or insufficient packaging pressure.

[0024] In some embodiments, the sealing head module 1 further includes a sealing electric cylinder 13 and a gantry frame 14. The sealing electric cylinder 13 is connected to the worktable via the gantry frame 14 and is connected to the sealing head 11, which can drive the sealing head 11 to move in a third direction. The gantry frame 14 structure provides stable support and guidance, and the cylinder drive enables rapid response and precise position control. Working in conjunction with the servo module 3, it achieves precise positioning in multiple directions, enabling automatic sealing of the needle tube.

[0025] In some embodiments, the servo module 3 includes a first module 31 and a second module 32. The first module 31 is connected to the worktable, and the second module 32 is disposed above the first module 31. The second module 32 can drive the alignment plate 2 to move in a second direction, and the first module 31 can drive the second module 32 to move in the first direction. The first module 31 is connected to the worktable and is responsible for driving the second module 32 to move in the first direction. The second module 32 is disposed above the first module 31 and is responsible for driving the alignment plate 2 to move in the second direction. The alignment plate 2 is disposed above the servo module 3 and includes a plurality of alignment through holes 21 for positioning the needle tubes 7. The first module 31 and the second module 32 achieve precise positioning of the alignment plate 2 in the X and Y directions. In conjunction with the pressure sensor 12, the packaging pressure is monitored in real time to ensure product quality.

[0026] See appendix Figure 3-6 As shown, in some embodiments, the alignment plate 2 is disposed above the servo module 3, and a plurality of alignment through holes 21 are provided along the thickness direction of the alignment plate 2. The alignment through holes 21 are perpendicular to the upper or lower surface of the alignment plate 2.

[0027] The through-holes 21 include a first through-hole 211 and a second through-hole 212 that are connected. The first through-hole 211 is located above the second through-hole 212 and is connected to the upper surface of the alignment plate 2. The first through-hole 211 and the second through-hole 212 are coaxially arranged. The first through-hole 211 is a frustum-shaped hole, wider at the top and narrower at the bottom. The angle between the generatrix of the first through-hole 211 and its axis is a first included angle 2111, with an angle of 40-60°. The second through-hole 212 is also a frustum-shaped hole, and the angle between the generatrix of the second through-hole 212 and its axis is a second included angle 2121, with an angle of 20-40°. The angles of the first included angle 2111 and the second included angle 2121 in the through-holes 21 are 40-60° and 20-40°, respectively, to ensure precise positioning of the needle tube 7.

[0028] The through holes 21 also include a third through hole 213 coaxially arranged with the first through hole 211. The upper end of the third through hole 213 is connected to the lower end of the second through hole 212. The third through hole 213 has a cylindrical structure and the diameter of the third through hole 213 is not less than the outer diameter of the needle tube 7. The through holes 21 also include a fourth through hole 214 coaxially arranged with the first through hole 211. The upper end of the fourth through hole 214 is connected to the lower end of the third through hole 213. The diameter of the fourth through hole 214 is less than the outer diameter of the needle tube 7.

[0029] The through-holes employ a three-stage decreasing diameter design: first through-hole 211 (frustum-shaped) → second through-hole 212 (frustum-shaped) → third through-hole 213 (cylindrical) → fourth through-hole 214 (small diameter). The third through-hole 213 provides sufficient space for the needle tube 7 to pass through smoothly, while the fourth through-hole 214 serves for precise positioning and limiting. All through-holes remain coaxial, ensuring the perpendicularity and positioning accuracy of the needle tube 7. This multi-stage diameter design enables progressive positioning and guidance of the needle tube 7, ensuring that the needle tube 7 can smoothly enter the alignment plate 2 and achieve precise alignment at the final position, preventing the needle tube 7 from being skewed or damaged.

[0030] A fixing through hole 22 is provided near the edge of the alignment plate 2. A pin passes through the fixing through hole 22 to detachably connect the alignment plate 2 and the servo module 3. The connection with the alignment plate 2 via the pin facilitates maintenance and replacement. In some embodiments, the device further includes a frame 4, on which a housing 5 is mounted, and a display screen 6 is also mounted. The frame 4, as the main structure of the device, through the rational arrangement of the housing and the display screen 6, ensures both the protection of the device and provides a convenient human-machine interface.
