Detailed ways

In order for those skilled in the art to better understand the technical solutions provided by the present invention, the following will be described in conjunction with specific embodiments.

Please refer to FIG. 1 , which is a diagram of the usage state of the imaging detection device for small packs of cigarettes in the embodiment of the present invention.

The imaging detection device for small cigarette case packaging provided by the embodiment of the present invention includes a mirror 2, a conveying mechanism 3, a camera 1 and a controller (not shown in the figure), the controller is electrically connected to the camera 1, and the controller can be Programmable logic controller (PLC), the reflective mirror 2 includes a first mirror 21 and a second mirror 22, the first mirror 21 and the second mirror 22 are spliced together, the first mirror 21 reflects the first side 41 of the cigarette case 4, the second Two mirrors 22 reflect the front 42 of the cigarette case 4, the camera 1 faces the second side 43 of the reflective mirror 2 and the cigarette case 4; the conveying mechanism 3 transports the cigarette case 4, and the cigarette case 4 after the transparent film is packaged is sent to the reflector 2 times. There are two sets of mirrors 2 and cameras 1 , one of which detects one end of the cigarette case 4 in the longitudinal direction, and the other detects the other end of the cigarette case 4 in the longitudinal direction.

Since the transparent film packaging adopts a high-temperature hot pressing process, the moisture and volatile substances in the transparent film are easily transferred to the lens of the camera 1 and the reflector 2, and the moisture and volatile substances are easy to accumulate here to form fog and droplets. The lens of camera 1 and reflector 2 are interfered by mist and liquid droplets to cause misjudgment and false rejection. In the present invention, the lens of camera 1 is vertically placed and installed in the forward direction of cigarette case 4, thereby reducing the chance of fogging . In addition, since the reflecting mirror 2 is installed on the top of the cigarette pack, if it is not treated, it will be easy to fog. For this reason, the present invention has pasted a layer of anti-fog film on the first mirror surface 21 and the second mirror surface 22, and on the camera 1 and the second mirror surface 22. Reflective mirror 2 is equipped with a heater to keep the temperature of the lens of camera 1 and reflective mirror 2 at about 60° C. to 70° C., preventing condensation of moisture and volatile matter on the lens of camera 1 and reflective mirror 2 .

The first mirror 1 of the reflective mirror 2 can observe the first side 41 of the cigarette case 4 directly below it, the second mirror 22 of the reflective mirror 2 can observe the front 42 of the cigarette case 1 directly below it, the first mirror 21 and the second The mirror 22 reflects the images of the first side 41 and the front 42 of the cigarette case 1 below it to the lens of the camera 1, and the camera 1 can also directly observe the second side 43 of the cigarette case 4, so that the camera 1 can observe the cigarette. On the first side 41, the front 42, and the second side 43 of the box 4, the video camera 1 takes pictures of the cigarette box 4 under the reflective mirror 2 at a shooting speed of 1000 pictures per second, and compares it with the cigarette box in the database. The standard image is compared, and when it does not match the standard image, the PLC control program issues an instruction for defective products. The rejecting mechanism is installed next to the conveying mechanism 3, and the rejecting mechanism is connected with the controller, and rejects the defective products after receiving the defective product instruction from the controller; the rejecting mechanism is an air cylinder.

Compared with the prior art, the imaging detection device for small packs of cigarettes provided by the present invention observes the first side and the front of the cigarette case through the first mirror surface and the second mirror surface of the mirror, and then reflects them to the camera for imaging, thereby The number of cameras is saved, and the cost of imaging detection of small cigarette packs is reduced.
