Description

Technical Field

[0001] The utility model relates to the field of optical fiber manufacturing, in particular to a negative pressure cleaning device. Background Art

[0002] In the field of optical fiber manufacturing, glass capillaries, used to sheath optical fibers, are commonly used components. Capillary blanks drawn from glass tubes are long and require cutting to become usable components. The inner surface of the cut capillary may contain debris or other residue, which reduces the yield rate. Cleaning the capillary improves product yield.

[0003] Currently, capillaries are usually cleaned manually one by one, which results in low cleaning efficiency.

[0004] Fiber optic raw materials also need to be cut before assembly. The surface of the cut fiber may also have debris or other residues, which will lead to a decrease in yield.

[0005] The transportation and preparation process of optical fibers and capillaries may also be contaminated by oil and dust, causing optical fiber wear and scattering, increased return loss, reduced optical signal-to-noise ratio, increased heat generation, and reduced efficiency. To improve product yield, the optical fiber and capillary need to be cleaned with alcohol or other cleaning fluids before assembly. After cleaning, the optical fiber and capillary are assembled. However, some cleaning fluid still remains in the capillary after assembly, and the cleaning fluid takes a long time to evaporate on its own, hindering the improvement of production efficiency. The cleaning fluid needs to be cleaned quickly. A single capillary is connected to a hollow rubber head as a negative pressure source via a rubber tube to aspirate the cleaning fluid in the capillary. However, only one capillary can be aspirated at a time, resulting in low work efficiency. Utility Model Content

[0006] The utility model aims to provide a negative pressure cleaning device which can improve the cleaning efficiency of cleaning liquid.

[0007] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0008] A negative pressure cleaning device includes a seat body and multiple valve bodies fixed on the seat body; the seat body is provided with a negative pressure chamber, a negative pressure channel, a suction pipe and a discharge pipe; the suction pipe is connected to the negative pressure chamber; the discharge pipe is connected to the negative pressure chamber; one end of the negative pressure channel is connected to the negative pressure chamber, and the other end is connected to the discharge port of the corresponding valve body; the inlet of the valve body is used to communicate with the object to be sucked.

[0009] As can be seen from this, each object to be suctioned can be connected to the negative pressure chamber separately through the valve body. The valve body corresponding to the object to be suctioned that has been suctioned and cleaned first is closed first, without affecting the cleaning of the remaining objects to be suctioned. Multiple objects to be suctioned can be suctioned and cleaned at one time, with high cleaning efficiency. The number of valve bodies corresponding to the number of objects to be suctioned that need to be cleaned is opened, and the remaining valve bodies are closed. That is, the number of objects to be suctioned and cleaned each time can be adjusted at any time, which is flexible in operation and can effectively reduce production costs.

[0010] Furthermore, the suction pipe is connected to the first end of the negative pressure chamber; the liquid discharge pipe is connected to the first end of the negative pressure chamber and is located at the lower side of the suction pipe. The upper side is used for suction and the lower side is used for liquid discharge, which is beneficial to gas-liquid separation.

[0011] Furthermore, a detachable plug is provided at the second end of the negative pressure chamber. After the plug is removed from the seat body, the negative pressure chamber can be easily cleaned.

[0012] Furthermore, the suction pipe and the discharge pipe are mounted on the base through the cover; a sealing ring is provided between the cover and the base, which facilitates the processing, molding and cleaning of the negative pressure chamber.

[0013] Furthermore, a trumpet-shaped opening is provided at the first end of the negative pressure chamber; the suction pipe is connected to the top of the trumpet-shaped opening; and the discharge pipe is connected to the bottom of the trumpet-shaped opening. Increasing the distance between the suction pipe and the discharge pipe is beneficial to improving the gas-liquid separation quality.

[0014] Furthermore, along the width direction of the negative pressure cleaning device, the main cavity of the negative pressure chamber is offset from the suction channel of the suction pipe and the discharge channel of the discharge pipe, thereby preventing cleaning liquid droplets from flying into the suction channel in a straight line, thereby improving the gas-liquid separation quality.

[0015] Furthermore, a baffle for shielding the lower side of the suction channel is fixed to the cover body by screws, making the airflow path more tortuous, which is beneficial to improving the quality of gas-liquid separation.

[0016] Furthermore, the baffle blocks the upper side of the drainage channel, which can reduce the diameter of the drainage channel entrance and prevent foreign matter from entering the drainage channel.

[0017] Furthermore, the outlet is connected to the negative pressure channel through a first adapter tube, and the inlet is connected to the object to be pumped through a second adapter tube. Preferably, the object to be pumped is a glass capillary tube equipped with an optical fiber.

[0018] Furthermore, a support is fixed to the base; a slot is provided on the upper side of the support, and each valve body is mounted on a corresponding slot; a support surface is also provided on the upper side of the support for supporting the object to be pumped. This reduces the flexural torque applied to the capillary tube, thereby protecting the capillary tube and preventing it from being damaged by prying. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, the negative pressure cleaning device 100 includes a base body 10 and a plurality of valve bodies 20 fixed on the base body 10; a negative pressure chamber 11, a negative pressure channel 12, a suction pipe 13 and a discharge pipe 14 are provided on the base body 10; the suction pipe 13 is connected to the negative pressure chamber 11; the discharge pipe 14 is connected to the negative pressure chamber 11; one end of the negative pressure channel 12 is connected to the negative pressure chamber 11, and the other end is connected to the discharge port 22 of the corresponding valve body 20; the inlet 21 of the valve body 20 is used to communicate with the object to be sucked 150.

[0027] Each object 150 to be suctioned can be individually connected to the negative pressure chamber 11 through a valve body 20. The valve body 20 corresponding to the object 150 to be suctioned that has been cleaned first is closed first, without affecting the cleaning of the remaining objects 150 to be suctioned. This allows multiple objects 150 to be suctioned to be cleaned at once, improving cleaning efficiency. The number of valve bodies 20 corresponding to the number of objects 150 to be suctioned 150 to be cleaned can be adjusted at any time, providing flexible operation.

[0028] Preferably, the suction pipe 13 is connected to the first end 111 of the negative pressure chamber 11; the liquid discharge pipe 14 is connected to the first end 111 of the negative pressure chamber 11 and is located at the lower side of the suction pipe 13. Suctioning gas from the upper side and discharging liquid from the lower side is beneficial to gas-liquid separation.

This facilitates the processing, molding, and cleaning of the negative pressure chamber 11. Preferably, the cover 15 is mounted on the sink 18 of the base 10 via screws 17, facilitating the miniaturization of the negative pressure cleaning device 100.

Increasing the distance between the suction pipe 13 and the discharge pipe 14 is conducive to improving the quality of gas-liquid separation.

[0032] Preferably, along the width direction 01 of the negative pressure cleaning device 100, the main cavity 110 of the negative pressure chamber 11 is offset from the suction channel 130 of the suction pipe 13 and the drainage channel 140 of the drainage pipe 14. This prevents cleaning droplets from flying into the suction channel 130 in a straight line, which is beneficial to improving the quality of gas-liquid separation.

[0033] Preferably, a baffle 152 for blocking the lower side of the suction channel 130 is fixed to the cover 15 by screws 151, making the air flow path more tortuous, which is conducive to improving the quality of gas-liquid separation.

This reduces the flexural torque applied to the capillary tube, thereby protecting the capillary tube and preventing it from being damaged by prying.

[0037] Preferably, the negative pressure source connected to the suction pipe 13 is a vacuum pump.
