[0031] The sealing detection mechanism comprises a plurality of visual cameras 13, and a mounting rack 11 is connected to the first rack 1, and the plurality of visual cameras 13 are mounted on the mounting rack 11.

[0032] The label roll 24 comprises a transparent film 241, a release paper 242 and a plurality of labels 243 equidistantly arranged between the transparent film 241 and the release paper 242.

[0033] The winding mechanism is mounted on the second rack 8 for winding the transparent film 241 and the release paper 242, and the winding mechanism comprises a unwinding roller 18, a first winding roller 19, a limiting roller 20, a second winding roller 21, a first servo motor 25 and a second servo motor 26, wherein the limiting roller 20 is provided with two in parallel, the unwinding roller 18, the first winding roller 19, the second winding roller 21 and the two limiting rollers 20 are rotatably installed on the second rack 8, the first servo motor 25 and the second servo motor 26 are mounted on the second rack 8, the output shafts of the first servo motor 25 and the second servo motor 26 are connected with the first winding roller 19 and the second winding roller 21 respectively, one end of the label roll 24 is fixed on the unwinding roller 18, the other end of the transparent film 241 is fixed on the first winding roller 19, the transparent film 241 is wound around the two limiting rollers 20, and one end of the release paper 242 is fixed on the second winding roller 21.

[0036] Specifically, when the injection product is detected and labeled, the product is placed inside the limiting ring 4, or the product can be placed upside down. If the product is not obviously leaking, the inverted method can more easily determine whether the product is leaking by observing the flow of droplets.

[0037] The first fixed plate 281, the moving plate 282 and the second fixed plate 283 are provided to limit the bottom end of the product. The power assembly drives the conveyor belt 2 to move, and the conveyor belt 2 moves the product. When the product moves to the position of the infrared distance sensor 23, the detection end of the infrared distance sensor 23 is blocked by the fixed frame 5, causing the detection data to change. The infrared distance sensor 23 feeds back the signal to the controller, which controls the power assembly to stop driving. At this time, the product is located at the position of the multiple vision cameras 13. It should be noted that if the product is placed normally, the multiple vision cameras 13 are arranged above the conveyor belt 2. If the product is inverted, the multiple vision cameras 13 are located below the upper end surface of the conveyor belt 2.

[0038] After the detection work is completed, the power assembly continues to drive the conveyor belt 2 to move, and the next product moves to the detection work. The detected product moves to the moving plate 282. If the computer analyzes that the product is a defective product, the computer controls the third electric push rod 27 through the connected controller. The controller is a PLC controller or a microprocessor controller. The third electric push rod 27 drives the moving plate 282 to move, so that the defective product falls onto the second conveyor belt device 9 and is conveyed away. It should be noted that sponges are installed on the outer surfaces of the conveyor belts of the second conveyor belt device 9 and the third conveyor belt device 10, which can act as a buffer.

[0039] The qualified product is conveyed to the labeling station again, the first servo motor 25 and the second servo motor 26 drive the first winding roller 19 and the second winding roller 21 to rotate respectively, the first winding roller 19 and the second winding roller 21 wind the transparent film 241 and the release paper 242 respectively, the photoelectric sensor 22 can detect and distinguish the transparent material and the non-transparent material by emitting light and detecting the reflected or transmitted light; when the label 243 blocks the detection end of the photoelectric sensor 22, the photoelectric sensor 22 feeds back a signal to the controller immediately, the controller controls the first servo motor 25 and the second servo motor 26 to stop driving work, at this time, the label 243 is aligned with the product, the controller controls the first electric push rod 15 to work to drive the first pressing block 14 to move, so that the label 243 is adhered to the surface of the product, it should be noted that the side of the label 243 adjacent to the transparent film 241 is a printing surface, there is a certain viscosity between the printing surface and the transparent film 241, but the viscosity is not strong enough to paste the label 243 on the transparent film 241, and the non-printing surface of the label 243 has strong viscosity, so that the label 243 can be firmly pasted on the outer surface of the product; the product with the label 243 is moved to the position of the second labeling mechanism, at this time, the second electric push rod 17 drives the second pressing block 16 to move, the second pressing block 16 is made of flexible material, the second pressing block 16 moves to press the label 243 tightly on the surface of the product, so that the automatic labeling work is realized.

[0040] After the labeling work is completed, the product is moved along with the continuous movement of the conveying belt 2, and when the product is separated from the second fixed plate 283, the product falls onto the third conveying belt device 10 and is conveyed to the next station.
