The lower end of the second rotating rod 232 at the upper end is rotatably connected to the light emitting tube 26. The outer wall of the light emitting tube 26 is provided with a triangular groove 261. The upper end of the second rotating rod 232 at the lower end is rotatably connected to the light receiving tube 27. The outer wall of the light receiving tube 27 is also provided with a triangular groove 261. The outer wall of the lower end of the rotating column 24 is provided with a third annular groove 242. The outer side of the third annular groove 242 is provided with a limiting assembly 25. The limiting assembly 25 includes a bending rod 252. One end of the bending rod 252 is fixedly connected to the first limiting column 251. The end of the bending rod 252 away from the first limiting column 251 is fixedly connected to the second limiting column 253. The first limiting column 251 is located inside the third annular groove 242, and the second limiting column 253 is located inside the triangular groove 261.

[0038] like Figure 8 As shown, the rotating assembly 3 includes a No. 3 rotating rod 31, and the No. 3 rotating rod 31 passes through the conveying plate 15. The upper outer wall of the No. 3 rotating rod 31 is fixedly connected to the No. 3 gear 32, and the lower outer wall of the No. 3 rotating rod 31 is fixedly connected to the turntable 33. The outer wall of the turntable 33 is provided with a plurality of arch holes 331, and the outer wall of the turntable 33 is fixedly connected to a rack 332, and the bottom of the lower end No. 2 gear 23 is fixedly connected to an extension rod 234, and the top of the extension rod 234 is fixedly connected to a protruding column 2341 at the end away from the No. 2 gear 23, and the diameter of the protruding column 2341 matches the width of the arch hole 331.

[0039] like Figure 8 As shown, the sealing assembly 4 includes a number four gear 41, which is meshed with the number three gear 32 and the turntable 33, a reciprocating screw 42 is fixedly connected to the bottom of the number four gear 41, an extrusion plate 43 is threadedly connected to the bottom of the reciprocating screw 42, a sliding rod 44 is fixedly connected to the top outer wall of the extrusion plate 43, and the sliding rod 44 is slidably connected to the outer wall of the number three rotating rod 31 at the end away from the extrusion plate 43.

[0040] It can be seen from this that when it is necessary to conduct multiple tests on some specific silicone products, such as Figure 3-Figure 8As shown, the staff first places the silicone sealing ring on the conveying column 152 from the feed port 11, and then the electric telescopic rod 16 pushes the pressing plate 161 to push the silicone sealing ring from the conveying cylinder 1521 to the conveying disc 15, as shown in FIG. Figure 5-Figure 8 As shown, at this time, the No. 1 rotating rod 22 rotates under the drive of the motor 13, and the No. 1 rotating rod 22 drives the No. 1 gear 221 at the upper and lower ends to rotate. At this time, the No. 1 gear 221 drives the No. 2 gear 23 at the upper and lower ends to rotate. At the same time, the No. 2 gear 23 at the lower end drives the extension rod 234 and the protruding column 2341 to rotate together. During the rotation of the protruding column 2341, the protruding column 2341 drives the turntable 33 to rotate 90 degrees in the arched hole 331 on the turntable 33 for each rotation. When the turntable 33 rotates 90 degrees, it drives the No. 3 rotating rod 31 and the conveying rod 151 to rotate 90 degrees. At this time, the silicone sealing ring on the conveying disc 15 is conveyed by the conveying rod 151 to the bottom of the light emitting tube 26;

[0041] At this time, when the first gear 221 drives the second gear 23 to rotate, the ball 2411 will roll in the first annular groove 231 and the second annular groove 241. Because the first annular groove 231 and the second annular groove 241 are both oblique annular grooves, the ball 2411 will gradually roll to the lowest point of the first annular groove 231 and the highest point of the second annular groove 241 when the second gear 23 drives the first annular groove 231 to rotate. At this time, the entire rotating column 24 slides downward (the lower end of the rotating column 24 slides downward). The movable column 24 moves upward in the same way), when the rotating column 24 moves downward, it will drive the No. 1 limiting column 251 to rotate downward together, and drive the bending rod 252 to rotate a certain angle, and at the same time, the No. 2 limiting column 253 is unfolded outward and releases the light emitting tube 26 (the same applies to the light receiving tube 27), and is pushed up and down by the spring 233 during the sliding process of the rotating column 24, so that the light emitting tube 26 and the light receiving tube 27 are close to each other, and the light transmission performance of the silicone seal is tested, and the light received by the light receiving tube 27 is tested to see if it meets the standard;

[0042] After the detection is completed, the third rotating rod 31 and the conveying rod 151 rotate again to convey the silicone seal to the position between the upper and lower extrusion plates 43. At this time, the lower extrusion plate 43 will lift the silicone seal and move down to the bottom of the conveying disc 15 under the influence of the reciprocating screw 42 during the process of the No. 1 gear 221 driving the No. 2 gear 23 to rotate (that is, the process of the conveying rod 151 rotating from the extrusion plate 43 to the conveying column 152). At this time, when the next silicone seal is conveyed to the top of the light collecting tube 27 by the conveying rod 151, the upper and lower extrusion plates 43 squeeze the silicone seal closed. At this time, the air delivery pump external to the air pipe 14 starts to deliver air to detect the sealing of the silicone sealing ring. The production process of this type of annular seal is relatively simple. When a large amount of detection work is required, it will be very time-consuming to detect multiple items. The present invention can ensure that multiple detection items are detected in the same device through the detection of the assembly line mode, saving time and effort.

[0043] It should be noted that when the extension rod 234 and the protruding column 2341 drive the rotating disk 33 and the No. 3 rotating rod 31 to rotate 90 degrees, the No. 2 gear 23 and the No. 3 gear 32 at the upper end are not meshed, and because the No. 3 gear 32 and the rotating disk 33 are meshed with the No. 4 gear 41 at the upper and lower ends, and because the outer wall rack 332 of the rotating disk 33 and the outer gear groove of the No. 3 gear 32 are distributed in a ratio of 2:1, when the No. 3 gear 32 drives the No. 4 gear 41 to rotate 90 degrees, the rotating disk 33 drives the No. 4 gear 41 to rotate 45 degrees, limiting the No. 3 gear 32 to drive the No. 4 gear 41 at the upper end to rotate every time 180 degrees, the upper extrusion plate 43 completes one reciprocating motion on the upper reciprocating screw 42, because the rotation angle of the No. 3 gear 32 is the same as that of the turntable 33, but the rotation angle of the lower No. 4 gear 41 driven by the turntable 33 is half of that of the upper No. 4 gear 41, so when the lower No. 4 gear 41 rotates 180 degrees after the upper No. 4 gear 41 rotates, the lower No. 4 gear 41 only rotates 90 degrees, that is, half a reciprocating motion, which limits the initial state of the upper and lower extrusion plates 43 to a closed state. When the conveying rod 151 in the above text rotates to the bottom of the conveying column 152 again, the upper and lower extrusion plates 43 clamp the silicone seal.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
