Description

Technical Field

[0001] The utility model relates to the field of optical fiber manufacturing, and particularly relates to a capillary cleaning device. Background Art

[0002] In the field of optical fiber manufacturing, capillaries made of glass for sheathing optical fibers are commonly used components. When the capillary blanks are drawn from glass tubes, they have a relatively large length and need to be cut into usable components. After cutting, there may be debris or other residues on the inner surface of the capillaries, resulting in a decrease in the yield. Therefore, the capillaries need to be cleaned to improve the product yield.

[0003] Currently, the cleaning method of capillaries is usually to clean them one by one manually, with low cleaning efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a capillary cleaning device that can improve the cleaning efficiency and reduce the production cost.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] The capillary cleaning device includes a basin body and a handle fixed on the basin body. The basin body is provided with a plurality of accommodation cavities extending in the height direction for accommodating capillaries. The upper end of the accommodation cavity penetrates through to the top surface of the basin body. The lower end of the accommodation cavity is communicated with the bottom surface of the basin body through a through hole. The average aperture at the connection of the through hole and the accommodation cavity is smaller than the average diameter of the lower end of the accommodation cavity.

[0007] It can be seen that the accommodation cavity can accommodate the capillaries to be cleaned, that is, the average aperture at the connection of the through hole and the accommodation cavity is smaller than the outer diameter of the capillary, preventing the capillary from falling out of the through hole. When the basin body is immersed in the cleaning liquid through the handle, the cleaning liquid can flow into the accommodation cavity from the through hole and submerge the capillaries; when the basin body is lifted from the cleaning liquid through the handle, the cleaning liquid carries the garbage and flows out from the through hole, thus completing the cleaning. Since each accommodation cavity can accommodate capillaries, multiple capillaries can be cleaned simultaneously, greatly improving the cleaning efficiency and reducing the production cost.

[0008] Further, along the radial direction of the basin body, the accommodation cavities are distributed outside the handle. This is convenient for setting the handle at the center of the basin body and is easy to control the balance of the basin body through the handle.

[0009] Further, the bottom of the basin body is provided with a plurality of feet. This is convenient for the cleaning liquid to flow into the accommodation cavity from the through hole.

[0010] Further, the height dimension of the accommodation cavity is greater than the height dimension of the capillary. The cleaning liquid can submerge the capillaries in the accommodation cavity, reducing the risk of garbage flowing from one accommodation cavity into another and further improving the cleaning efficiency.

[0011] Further, when the capillary is at the maximum inclination position, the projection of the center of gravity of the capillary on the horizontal plane is within the range of the projection of the lower end face of the capillary on the horizontal plane. This is conducive to the self-stabilization and upright state of the capillary by gravity, improving the efficiency of the cleaning liquid passing through the inner hole of the capillary and enhancing the cleaning efficiency and quality.

[0012] Further, a tapered hole is provided at the upper end of the handle. The opening at the upper end of the tapered hole is larger than that at the lower end, and the tapered hole is a blind hole. A tapered tube and a negative pressure channel are provided on the negative pressure manipulator. The tapered tube is inserted into the tapered hole, and the negative pressure channel is connected to a negative pressure source (not shown in the figure). The handle is sucked onto the negative pressure manipulator. The negative pressure manipulator can lift the basin out of the cleaning liquid, facilitating the automation of cleaning and improving the cleaning efficiency.

[0013] Further, the bottom wall of the accommodating cavity is a plane. This is convenient for the capillary to stand upright and self-stabilize.

[0014] Further, the capillary cleaning device further includes a cleaning tank. An ultrasonic vibration unit is provided on the cleaning tank. The ultrasonic vibration can be transmitted to the cleaning liquid and the capillary in the accommodating cavity through the cleaning liquid outside the basin and the basin, improving the cleaning efficiency and quality.

[0015] Further, along the vertical direction, the depth of the cleaning cavity of the cleaning tank is greater than the height of the basin. This is convenient for improving the transmission quality of the mechanical wave of the ultrasonic vibration and enhancing the cleaning efficiency. Description of the Drawings

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] As shown Figures 1-4 in FIG. 1, the capillary cleaning device 100 includes a basin body 10 and a handle 20 fixed on the basin body 10.

[0025] The basin body 10 is provided with a plurality of receiving cavities 11 extending in the height direction 001 for receiving capillaries 01.

[0026] The upper end of the receiving cavity 11 penetrates through to the top surface 101 of the basin body 10.

[0027] The lower end of the receiving cavity 11 is communicated with the bottom surface 102 of the basin body 10 through a through hole 12.

[0028] The average aperture diameter at the junction of the through hole 12 and the receiving cavity 11 is smaller than the average diameter of the lower end of the receiving cavity 11.

[0029] The receiving cavity 11 can accommodate the capillary 01 to be cleaned therein, that is, the average aperture diameter at the junction of the through hole 12 and the receiving cavity 11 is smaller than the outer diameter of the capillary 01, preventing the capillary 01 from falling out of the through hole 12. When the basin body 10 is immersed in the cleaning liquid through the handle 20, the cleaning liquid can flow into the receiving cavity 11 from the through hole 12 and submerge the capillary; when the basin body 10 is lifted from the cleaning liquid through the handle 20, the cleaning liquid carries the garbage and flows out from the through hole 12, thus completing the cleaning. Since each receiving cavity 11 can accommodate the capillary 01, multiple capillaries 01 can be cleaned simultaneously, greatly improving the cleaning efficiency and reducing the production cost.

[0030] Preferably, the handle 20 is fixed on the basin body 10 by means of screw fit, interference fit or bonding.

[0031] Preferably, along the radial direction of the basin body 10, the receiving cavities 11 are distributed outside the handle 20.

[0032] Preferably, the bottom of the basin body 10 is provided with a plurality of feet 13.

[0033] Preferably, as shown Figure 6 in FIG. 2, the height dimension of the receiving cavity 11 is greater than the height dimension of the capillary 01.

[0034] Preferably, as shown Figure 6 in FIG. 3, when the capillary 01 is at the maximum inclination position, the projection of the center of gravity 02 of the capillary 01 on the horizontal plane is within the range of the projection of the lower end surface of the capillary 01 on the horizontal plane. This is beneficial for the capillary to be self-stabilized and upright by gravity, improving the efficiency of the cleaning liquid passing through the inner hole of the capillary 01 and enhancing the cleaning efficiency and quality.

[0035] Preferably, as shown Figure 6 in FIGS. 4 Figure 7, a conical hole 21 is provided at the upper end of the handle 20. The opening at the upper end of the conical hole 21 is larger than the opening at the lower end, and the conical hole 21 is a blind hole. A conical tube 41 and a negative pressure channel 42 are provided on the negative pressure manipulator 40. The conical tube 41 is inserted into the conical hole 21, and the negative pressure channel 42 is communicated with a negative pressure source (not shown in the figure). The handle 20 is sucked onto the negative pressure manipulator 40. The negative pressure manipulator 40 can be lifted to take out the basin body 10 from the cleaning liquid, facilitating the automation of cleaning.

[0036] Preferably, the bottom wall 111 of the accommodating cavity 11 is a plane. It is convenient for the capillary 01 to stand upright and be self-stable.

[0037] Preferably, the capillary cleaning device 100 further includes a cleaning tank 30. An ultrasonic vibration unit 31 is provided on the cleaning tank 30. The ultrasonic vibration energy is transmitted to the cleaning liquid and the capillary 01 in the accommodating cavity 11 through the cleaning liquid outside the basin body 10 and the basin body 10, improving the cleaning efficiency and quality.

[0038] Preferably, along the vertical direction, the depth of the cleaning cavity 32 of the cleaning tank 30 is greater than the height of the basin body 10. It is convenient to improve the transmission quality of the mechanical wave of the ultrasonic vibration and improve the cleaning efficiency.
