As shown in fig. 1 to 5, an embodiment of the present disclosure provides a device for detecting a foreign object in a powder injection bottle. Specifically, the detection device comprises a clamping mechanism 1, a vibrator 2 and a light source assembly. Wherein the clamping mechanism 1 is used for clamping the powder injection bottle 100, and the clamping mechanism 1 is configured such that the body of the powder injection bottle 100 is arranged horizontally or obliquely to the horizontal plane. Vibrator 2 is connected with fixture 1, and vibrator 2 is configured to circulate and peristaltic the powder in powder injection bottle 100 along the axial direction of the bottle body. The light source assembly includes a first light source 31 disposed above the powder injection bottle 100 and a second light source 32 disposed below the powder injection bottle 100, and specifically, the first light source 31 may be considered as a front light source and the second light source 32 may be considered as a back light source. It should be noted that the powder injection bottle 100 is described as an environmental feature, and is not intended to limit the protection scope of the detection device.
By setting the vibration frequency and the working voltage of the vibrator 2, the powder in the powder injection bottle 100 can move in a certain direction, namely the vibration direction, and the powder is axially arranged from the bottle mouth to the bottle bottom, so that the powder peristaltic movement and detection are most facilitated, for example, a vibration feeder is arranged on a device for realizing vibration directional conveying, and the vibrator 2 can select an electromagnetic vibrator, a pneumatic vibrator, a piezoelectric ceramic vibrator, a flexible vibrator or a voice coil motor vibrator and the like according to different vibration sources or vibration principles. Alternatively, the vibrator 2 has a vibration frequency of 30HZ to 200HZ, and an operating voltage of 30V to 200V, preferably a vibration frequency of 66HZ. Fig. 2 shows that the body of the powder injection bottle 100 is placed at an angle close to the horizontal, and when the vibrator 2 works, the vibrator 2 drives the clamping mechanism 1 and further drives the powder injection bottle 100 connected with the clamping mechanism 1 to vibrate, and the powder in the powder injection bottle 100 and the foreign matters mixed in the powder also circulate and creep along the axial direction of the body.
Specifically, in fig. 2, the left side is the bottle mouth and the right side is the bottle bottom direction, and the direction from the bottle bottom to the bottle mouth or from the bottle mouth to the bottle bottom is the axial direction. Along with the vibration of the vibrator 2, the powder moves towards the bottle bottom, the powder is blocked and extruded at the bottle bottom to be gradually accumulated and raised, collapse and slide towards the bottle opening when the powder is raised to a certain height, and the powder is accumulated at the bottle bottom, is thinner and can transmit light. During this axial cyclic peristaltic movement of the powder, even foreign matter buried in the powder always has a moment of precipitation to the powder surface layer or movement to a thinner region of the powder edge with vibration and powder peristaltic movement.
While the powder in the bottle axially circulates and peristaltic, the first light source 31 and the second light source 32 are alternately made to irradiate the bottle body, and a surface image and a perspective image of the powder in the bottle body are respectively constructed. The brightness levels of the first light source 31 and the second light source 32 can also be adjusted for areas of different thickness of the powder in order to obtain clearer surface photos and perspective photos. For example, for a region with thicker powder, increasing the brightness level of the light source can obtain a clearer surface image and a perspective image, which is beneficial to increasing the detection rate of foreign matters, but for a region with thinner powder, the light source with higher brightness can cause overexposure, which is rather unfavorable to obtain a clear surface image and a perspective image. Thus, the brightness of the first light source 31 and the second light source 32 can be adjusted, and the surface image and the perspective image can be acquired in time-sharing and in area-division, i.e., in different periods of vibration, where the time-sharing is different in time-division, i.e., in area of different thickness of the powder.
The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: the detection device of the present disclosure uses the vibrator 2 to make the powder in the powder injection bottle 100 circulate and creep along the axial direction of the bottle body, so that even the foreign matters buried in the powder always have the moment of precipitating to the surface layer of the powder or moving to the thinner region of the powder edge along with vibration and powder creep, the thinner region is beneficial to perspective imaging, and the powder surface image and perspective image respectively obtained under the irradiation of the first light source 31 and the second light source 32 can be imaged or observed more easily, thereby improving the detection rate and detection efficiency of the foreign matters.
As shown in fig. 1, the detection device may further include a camera 200 for capturing images in the powder injection bottle 100, and in some usage scenarios, the camera 200 transmits the capturing results to an image analysis system in real time, and the image analysis system may preset image analysis software, and the image analysis software automatically analyzes whether the powder in the bottle is mixed with foreign matters by using an image recognition technology. The camera 200 can be used in combination with a light source assembly, specifically, when the brightness levels of the first light source 31 and the second light source 32 are adjusted, and the bottle body is illuminated in a time-sharing and area-division manner, the surface images and the perspective images of the powder in a plurality of bottles are photographed for recognition and analysis, so that the detection rate and the detection efficiency are improved.
In some embodiments, as shown in fig. 1 and 3, the detection device further includes a first lifting drive device 4 disposed above the powder injection bottle 100. The clamping mechanism 1 comprises a first clamping piece 11 and a second clamping piece 12 which are arranged at intervals up and down, wherein the first clamping piece 11 is arranged on the vibrator 2, the second clamping piece 12 is arranged on the first lifting driving device 4, the first lifting driving device 4 is used for driving the second clamping piece 12 to be close to or far away from the first clamping piece 11, specifically, the second clamping piece 12 is close to the first clamping piece 11 so as to clamp the powder injection bottle 100, and the second clamping piece 12 is far away from the first clamping piece 11 so as to loosen the powder injection bottle 100. Since the first clamping member 11 is connected with the vibrator 2, the vibrator 2 can drive the first clamping member 11 to vibrate when vibrating. Alternatively, as shown in fig. 2, a vibration table 21 may be provided on the vibrator 2, and the first clamping member 11 is provided on the vibration table 21.

An elastic member 5 is provided between the first clamping member 11 and the vibrator 2 and/or between the second clamping member 12 and the first lift driving device 4, and the elastic member 5 can provide an elastic force for driving the first clamping member 11 and the second clamping member 12 to approach each other.
