[0049] like Figure 4 As shown, the material storage box 110, the primary wheel disc 210, the secondary wheel disc 310, and the good product recovery box 130 are arranged in sequence from high terrain to low terrain, the discharge port of the material storage box 110 is connected to the primary wheel disc 210 via a front end inclined guide plate 410, the primary wheel disc 210 is connected to the secondary wheel disc 310 via a middle inclined guide plate 420, and the secondary wheel disc 310 is connected to the good product recovery box 130 via a rear end inclined guide plate 430.

[0050] like Figure 3 and Figure 4 As shown, the defective product recovery box 120 is located below the middle inclined guide plate 420 and the rear end inclined guide plate 430 .

[0051] Next, the specific structures of the primary roulette wheel 210 and the secondary roulette wheel 310 are described:

[0052] like Figure 5 and Figure 6 As shown, a plurality of primary receiving grooves 211 are arranged in a circular array on the primary wheel 210, and more than half of the side surfaces of the packaged products 10 falling into the primary receiving grooves 211 are exposed outside the grooves. The packaged products 10 falling into the primary receiving grooves 211 revolve around the rotating axis of the primary wheel 210 and cannot rotate on their own.

[0053] like Figure 5 and Figure 6 As shown, the secondary wheel 310 is provided with a plurality of secondary receiving grooves 311 distributed in a circular array, and more than half of the side surfaces of the packaged products 10 falling into the secondary receiving grooves 311 are exposed outside the grooves. The packaged products 10 falling into the secondary receiving grooves 311 revolve around the rotating axis of the secondary wheel 310 and cannot rotate on their own.

[0054] Next, the specific structures of the middle inclined guide plate 420 and the rear inclined guide plate 430 are described:

[0055] like Figure 6 As shown, a defective product drop hole 421 is provided on the plate surface of the middle inclined guide plate 420, and a defective product opening and closing bin door 422 is provided at the defective product drop hole 421;

[0056] Similarly, a secondary defective product drop hole (not shown) is opened on the plate surface of the rear end inclined guide plate 430, and a secondary defective product opening and closing bin door (not shown) is provided at the secondary defective product drop hole 431.

[0057] like Figure 2 As shown, further, the packaging product inspection device 20 with a visual inspection function further includes a driving device 500 drivingly connected to the primary wheel disc 210 and the secondary wheel disc 310, and the driving device 500 is used to drive the primary wheel disc 210 and the secondary wheel disc 310 to rotate intermittently;

[0058] like Figure 5 As shown, during the intermittent rotation of the primary wheel 210, there are always three primary receiving slots 211 facing the primary CCD camera 220;

[0059] like Figure 5As shown, during the intermittent rotation of the secondary wheel 310 , there are always three secondary receiving slots 311 facing the secondary CCD camera 320 .

[0060] Next, the working principle of the above-mentioned packaging product inspection device 20 with visual inspection function is described:

[0061] like Figure 5 As shown, several packaged products 10 to be tested are placed in the storage box 110, and the axis of the cylindrical packaged products 10 is parallel to the horizontal plane, that is, each packaged product 10 is in a flat state, and the packaged products 10 fall out from the discharge port of the storage box 110 one by one, and slide along the front inclined guide plate 410 to the primary receiving groove 211 of the primary wheel 210 under the action of gravity; in the present invention, a vibrator can be provided at the storage box 110, so that the several packaged products 10 in the storage box 110 can fall out from the discharge port more smoothly;

[0062] like Figure 6 and Figure 7 As shown, since more than half of the side surface of the packaged product 10 falling into the primary receiving groove 211 is exposed outside the groove, the side surface of the packaged product 10 exposed outside the groove is divided into three areas A, B, and C. With the intermittent rotation of the primary wheel 210, the primary CCD camera 220 can clearly take pictures of the three areas A, B, and C respectively;

[0063] like Figure 6 As shown, when the packaged product 10 stays at the lower left of the primary CCD camera 220, the primary CCD camera 220 takes a picture of area A; when the packaged product 10 stays directly below the primary CCD camera 220, the primary CCD camera 220 takes a picture of area B; when the packaged product 10 stays at the lower right of the primary CCD camera 220, the primary CCD camera 220 takes a picture of area C;

[0064] When the primary wheel 210 rotates to a designated position, under the action of gravity, the packaged product 10 will be separated from the primary receiving groove 211 and slide down along the middle inclined guide plate 420;

[0065] If the primary CCD camera 220 detects that the graphic mark on the side of the packaged product 10 has no defects, the packaged product 10 will slide directly along the middle inclined guide plate 420 into the secondary receiving groove 311 of the secondary wheel 310; if the primary CCD camera 220 detects that the graphic mark on the side of the packaged product 10 has defects, the primary defective product opening and closing door 422 causes the primary defective product drop hole 421 to be in an open state, and the packaged product 10 falls from the primary defective product drop hole 421 into the defective product recovery box 120;

[0066] The other side of the packaged product 10 that has arrived in the secondary receiving groove 311 continues to be inspected. It should be particularly noted that during the process of the packaged product 10 sliding down along the middle inclined guide plate 420, the packaged product 10 itself will roll. Through calculation, the length of the middle inclined guide plate 420 is artificially adjusted, so that the other side of the packaged product 10 is exposed outside the secondary receiving groove 311.

[0067] Since more than half of the side surface of the packaged product 10 falling into the secondary receiving groove 311 is exposed outside the groove, the side surface of the packaged product 10 exposed outside the groove is divided into three areas D, E, and F. With the intermittent rotation of the secondary wheel 310, the secondary CCD camera 320 can clearly take pictures of the three areas D, E, and F respectively;

[0068] When the packaged product 10 stays at the lower left of the secondary CCD camera 320, the secondary CCD camera 320 takes a picture of the D area; when the packaged product 10 stays directly below the secondary CCD camera 320, the secondary CCD camera 320 takes a picture of the E area; when the packaged product 10 stays at the lower right of the secondary CCD camera 320, the secondary CCD camera 320 takes a picture of the F area;

[0069] When the secondary wheel 310 rotates to a specified position, under the action of gravity, the packaged product 10 will be separated from the secondary receiving groove 311 and slide along the rear end inclined guide plate 430;

[0070] Similarly, if the secondary CCD camera 320 detects that there is no defect in the graphic label on the side of the packaged product 10, the packaged product 10 will slide directly into the good product recovery box 130 along the rear end inclined guide plate 430; if the secondary CCD camera 320 detects that there is a defect in the graphic label on the side of the packaged product 10, the secondary defective product opening and closing door causes the secondary defective product drop hole to be in an open state, and the packaged product 10 falls from the secondary defective product drop hole into the defective product recovery box 120.

[0071] It should be noted that during the visual inspection process, when the primary wheel 210 and the secondary wheel 310 drive the packaged product 10 to rotate, the packaged product 10 will not rotate in the receiving slot. In this way, it can be ensured that the primary CCD camera 220 and the secondary CCD camera 320 can accurately and clearly capture the A, B, C, D, E, and F areas on the side of the packaged product 10 (such as Figure 7 As shown in FIG. 1 ), visual inspection of the entire side area of ​​the packaged product 10 without blind spots is achieved. In order to better prevent the packaged product 10 from rotating in the receiving groove, anti-slip pads can be provided at the bottom of the primary receiving groove 211 and the bottom of the secondary receiving groove 311 to increase friction.

[0072] It should be particularly noted that, in the present invention, more than half of the side surfaces of the packaged product 10 falling into the primary receiving groove 211 are exposed outside the groove, and more than half of the side surfaces of the packaged product 10 falling into the secondary receiving groove 311 are exposed outside the groove. In this way, when the two "half sides" of the packaged product 10 are interchanged for inspection, the problem of the junction being blocked by the receiving groove and unable to be fully inspected will not occur.

[0073] In the present invention, the graphic marks of the packaged products 10 in the storage box 110 do not need human intervention in advance to be arranged in order. It is only necessary to stack a number of packaged products 10 in a flat state in the storage box 110, and the detection can be completed efficiently. When a certain packaged product 10 falls out of the discharge port of the storage box 110 and slides into the primary receiving groove 211 of the primary wheel 210 along the front inclined guide plate 410 under the action of gravity, the graphic mark on one side of the packaged product 10 is also randomly exposed outside the groove, but this does not affect the subsequent complete visual inspection of the graphic mark on the entire side of the packaged product 10. It should be noted that the present invention defines A, B, C, D, E, and F areas. These defined areas do not absolutely and fixedly define the graphic marks of a certain area. It can be understood that the A, B, C, D, E, and F areas are a spatial concept. According to the different positions where the packaged product 10 falls into the receiving groove for the first time, the A, B, C, D, E, and F areas will also change accordingly.

[0074] The present invention also discloses a packaging product detection method, which is used to visually detect the graphic mark on the side of the cylindrical packaging product, and is implemented by the packaging product detection device with visual detection function, including the following steps:

[0075] S1, placing a number of packaged products to be inspected in a storage box, and the packaged products slide from the discharge port of the storage box along the front inclined guide plate to the primary receiving slot of the primary wheel, and the side of the packaged products exposed outside the primary receiving slot is divided into three areas A, B, and C;

[0076] S2, the wheel rotates intermittently, driving the packaged products in the receiving slot to revolve intermittently. When the revolution stops, a CCD camera takes pictures of the three areas A, B, and C respectively;

[0077] S3, if the graphic labels in the three areas A, B, and C are qualified, the packaged product slides from the primary receiving slot of the primary wheel along the middle inclined guide plate to the secondary receiving slot of the secondary wheel; if the graphic labels in the three areas A, B, and C are unqualified, the primary defective product opening and closing bin door causes the primary defective product drop hole to be in an open state, and the packaged product falls from the primary receiving slot of the primary wheel along the middle inclined guide plate from the primary defective product drop hole to the defective product recovery box;

[0078] S4, dividing the side of the packaged product that falls into the secondary receiving tank and is exposed outside the tank into three areas D, E, and F, and the secondary wheel rotates intermittently to drive the packaged product in the secondary receiving tank to revolve intermittently. When the revolution stops, the secondary CCD camera takes pictures of the three areas D, E, and F respectively;

[0079] S5, if the graphic labels in the three areas D, E, and F are qualified, the packaged products slide from the secondary receiving groove of the secondary wheel along the rear end inclined guide plate to the good product recycling box; if the graphic labels in the three areas D, E, and F are unqualified, the secondary defective product opening and closing door causes the secondary defective product drop hole to be in an open state, and the packaged products fall from the secondary defective product drop hole from the secondary receiving groove of the secondary wheel along the rear end inclined guide plate to the defective product recycling box.

[0080] like Figure 7 As shown, in this embodiment, the side of the packaged product is divided into six arc-shaped areas of equal area, A, B, C, D, E, and F, in sequence, and the arc of each arc-shaped area is greater than 60° (preferably 62°), and the intersection of the arc-shaped area A and the arc-shaped area F has an overlapping portion G, and the intersection of the arc-shaped area C and the arc-shaped area D has an overlapping portion H. In this way, when the two "half sides" of the packaged product 10 are interchanged for inspection, the problem of being blocked by the receiving groove at the intersection and unable to be fully inspected will not occur, and complete inspection can be achieved.

[0081] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
