Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

Based on the foregoing, in the prior art, manual detection is generally adopted, specifically, an air gun is used to blow air inwards at one end of an inner cavity channel of a component, and the air quantity is sensed at the other end of the inner cavity channel by hand, so as to determine whether the inner cavity channel is unobstructed. However, the detection result is not accurate enough by sensing the air volume by hand, and in addition, when detecting the component with a plurality of inner cavity channels, the detection needs to be performed in the inner cavity of the channel one by one, so that the detection efficiency is low.

In order to solve the above-mentioned problems, referring to fig. 1 to 4, the present embodiment provides a lumen channel blockage detection device for detecting blockage of a plurality of lumen channels of a component 100, wherein the lumen channel blockage detection device includes a carrier 1, a fixing component 2, a communicating component 3, a gas source (not labeled in the drawing), a driving component 4 and a detection component (not labeled in the drawing). The fixing assembly 2 is provided on the carrier 1, and the fixing assembly 2 is configured as a fixing member 100. The communication assembly 3 is slidably disposed on the carrier 1 along a predetermined direction, and the communication assembly 3 is configured to communicate with one ends of the plurality of inner cavity channels. In this embodiment, the preset direction is a vertical direction. The air supply is configured to blow air through the communication assembly 3 into the plurality of lumen passages together. The driving member 4 is disposed on the carrier member 1, and the driving member 4 is configured to drive the communication assembly 3 to slide. The detection assembly is configured to detect a pressure value at the other end of the plurality of lumen channels. It should be noted that the air source is preferably an air compressor in the prior art, and the air compressor and its working principle are all well known to those skilled in the art, so that no description is repeated.

The embodiment further provides a lumen channel detection method implemented according to the lumen channel blockage detection device, where the lumen channel detection method includes the following steps:

placing and fixing the component 100 on the fixed assembly 2;

the driving piece 4 drives the communicating component 3 to slide so that the gas source can be communicated with one end of a plurality of inner cavity channels on the component 100 through the communicating component 3;

It is understood that the way in which the pressure value is detected by the detection assembly can accurately feed back the degree of blockage of the lumen channel. It will be further appreciated that the air source is coupled to the plurality of lumen passages on the component 100 via the connection assembly, i.e., the plurality of lumen passages on the component 100 can be detected together, thereby facilitating improved detection efficiency.

The fixing assembly 2 includes a plurality of supporting members 21 and a plurality of limiting members 22. A plurality of supports 21 are distributed on the carrier 1, the plurality of supports 21 being configured to support different positions of the component 100. The plurality of limiting members 22 are distributed on the carrier 1, and the plurality of limiting members 22 are configured to be in clamping fit with the reserved holes at different positions of the component 100. It should be noted that, the arrangement positions of the plurality of limiting members 22 and the plurality of supporting members 21 are designed according to the structural dimensions of the component 100, which is not described in detail in this embodiment. To reduce damage to the component 100, rubber pads are adhered to the end surfaces of all the supporting members 21 and the limiting members 22 contacting the component 100. It will be appreciated that the use of multiple supports 21 to support the component 100 at multiple different locations enables a more stable support of the component 100. It will also be appreciated that the use of a plurality of retainers 22 that are engaged with the preformed holes in different locations of the component 100 can result in a more secure fixation of the component 100. In addition, the component 100 is fixed by clamping, so that the structure is simple, and the operation is convenient. Of course, in other embodiments, the component 100 may be fixed by plugging, abutting, etc., which will not be described in detail in this embodiment.

To improve the applicability of the device for detecting the blockage of the inner cavity channel, specifically, when the inner cavity channel of the component 100 has three communication ports, the limiting piece 22 can be in clamping fit with the end of the inner cavity channel and seal the inner cavity channel, so that the inner cavity channel is only air-out from one communication port, and further normal operation of the blockage detection work can be ensured. It will be appreciated that the use of the stop 22 to seal the ends of the excess lumen channel does not require additional structure and helps reduce the cost of use of the lumen channel blockage detection device.

The detection component comprises a plurality of detection pieces, the detection pieces are arranged at the other ends of the inner cavity channels in a one-to-one correspondence mode, and the detection pieces are configured to detect pressure values at the other ends of the inner cavity channels corresponding to the detection pieces.
