[0020] Please refer to Figure 1 , Figure 2 The present application discloses a batch six-surface detection equipment, comprising: A batch six-surface detection equipment comprises a feeding conveying section 1, a front shunt conveying section 2, a first turnover mechanism 3, a rear shunt conveying section 4, a discharging conveying section 5, a second turnover mechanism 6, an output section 7 and a disposal section 8.

It also comprises multiple detection groups, each of which is distributed at the feeding conveying section 1, the front shunt conveying section 2, the first turnover mechanism 3, the rear shunt conveying section 4, the discharging conveying section 5 and the output section 7 and is used for checking the six sides of the package boxes 9. Specifically, the multiple detection groups can be arranged in the following manner: Three visual imagers are arranged and distributed on the left and right sides and above the feeding conveying section 1 and are used for detecting the left and right sides and the front side of the package boxes 9; one visual imager is arranged and distributed above the discharging conveying section 5 and is used for detecting the back side of the package boxes 9; and two visual imagers are arranged and distributed on both sides of the output section 7 and are used for detecting the front and back sides of the package boxes 9.

[0021] In work, the packaging box 9 is integrally fed by the feeding conveying section 1, then is separated by the separation conveying front section 2, the separated packaging box 9 enters the corresponding first turnover mechanism 3 to be turned over by 180°, and then is combined to the discharging conveying section 5; the combination-separation-combination process can effectively improve the turnover efficiency of the packaging box 9, and then improve the overall working efficiency of the production line, realize large-scale detection, and through the detection groups distributed at the feeding conveying section 1, the separation conveying front section 2, the first turnover mechanism 3, the separation conveying rear section 4, the discharging conveying section 5 and the output section 7, the six surfaces of the packaging box 9 can be inspected during the rapid movement of the packaging box 9, and then the packaging box 9 after inspection enters the disposal section 8, so that the defective packaging box and the good packaging box 9 are output respectively.

[0022] It should be pointed out that the technical scheme of the application has a control processor, which receives the packaging box 9 view information collected by each detection group and judges the defects, and then controls the disposal section 8 to kick out the defective packaging box 9 based on the judgment result.

[0023] As shown in Figure 2 , the separation conveying front section 2 is vertically arranged at the output end of the feeding conveying section 1, and includes a plurality of first conveying lines 21 and a plurality of first pushing mechanisms 22. The feeding conveying section 1 synchronously conveys a plurality of packaging boxes 9 to each first pushing mechanism 22, and each first pushing mechanism 22 synchronously pushes the corresponding packaging box 9 onto the corresponding first conveying line 21. In this way, the packaging boxes 9 on the feeding conveying section 1 can be separated into the first conveying lines 21, so that a plurality of packaging boxes 9 are synchronously conveyed to the first turnover mechanism 3 for turnover.

[0024] As shown in Figure 3 , a plurality of the first turnover mechanisms 3 are coaxially arranged and synchronously rotated by a driving mechanism 33; The first turnover mechanism 3 is provided with a plurality of receiving boxes 31 arranged in a ring shape, and the receiving box 31 is provided with a containing groove 312 for containing the packaging box 9. When the receiving box 31 is aligned with the corresponding first conveying line 21, the first conveying line 21 sends the packaging box 9 into the receiving box 31.

[0025] Specifically, in order to further ensure that the packaging box 9 can enter the containing groove 312, the receiving box 31 is designed as two blocks 311 arranged at intervals, and the facing sides of the two blocks 311 are provided with grooves, and the grooves on the two blocks 311 combine to form the containing groove 312, and one end of the first conveying line 21 extends into the space between the two blocks 311. In this way, the packaging box 9 can be better sent into the containing groove 312.

[0026] Preferably, the first conveying line 21 is provided with guide plates on both sides for guiding the packaging box 9, preventing the packaging box 9 on the first conveying line 21 from falling off and guiding the packaging box 9 into the containing groove 312. In order to avoid interference between the guide plates and the first turnover mechanism 3, no guide plates are provided at the position where the receiving box 31 is aligned with the corresponding first conveying line 21.

[0027] Preferably, the driving mechanism 33 is an electric motor.

[0028] As shown in Figure 4 , the split conveying rear section 4 comprises a plurality of second conveying lines 41 and a plurality of second pushing mechanisms 42. The plurality of second conveying lines 41 drive the overturned packaging box 9 to move towards the unloading conveying section 5. The second pushing mechanism 42 is used to push the packaging box 9 on the second conveying line 41 onto the unloading conveying section 5.

[0029] Specifically, in order to further ensure that the packaging box 9 can be output from the containing groove 312, one end of the second conveying line 41 also extends between the left and right blocks 311, and guide plates are also provided on both sides of the second conveying line 41.

[0030] Preferably, the first pushing mechanism 22 and the second pushing mechanism 42 have the same structure, both comprising a belt conveying structure provided with a pushing block on the conveying belt of the belt conveying structure. The first pushing mechanism 22 is arranged above the first conveying line 21 and the feeding conveying section 1, and pushes the packaging box 9 on the feeding conveying section 1 onto the corresponding first conveying line 21 through the corresponding pushing block. The second pushing mechanism 42 is arranged above the second conveying line 41 and the unloading conveying section 5, and pushes the packaging box 9 on the second conveying line 41 onto the unloading conveying section 5 through the corresponding pushing block.

[0031] It should be noted that the first pushing mechanism 22 and the second pushing mechanism 42 can also adopt other pushing forms, such as the form of pneumatic telescopic cylinder + pushing block, or the form of electric telescopic rod + pushing block, etc. However, the pneumatic telescopic cylinder and the electric telescopic rod have slow response and short service life, and are not suitable for the rhythm of high-speed production. Therefore, the belt conveying structure + pushing block structure form is preferably selected.

[0032] As shown in Figure 4 , Figure 5 , the second turnover mechanism 6 comprises: a first pushing component 61 for pushing the packaging box 9 from one side of the unloading conveying section 5; a guide component 62 arranged on one side of the unloading conveying section 5 for receiving the packaging box 9 pushed by the first pushing component 61 and overturning the packaging box 9 by 90° from a lying state to a standing state, so that the overturned packaging box 9 is overturned by 270° compared with the posture before entering the first turnover mechanism 3.

[0033] Specifically, the guide part 62 is a chute, which is used to quickly overturn the packaging box 9. The first pushing part 61 has the same structure as the first pushing mechanism 22, which is a belt conveying structure + push block structure, and is used to push the packaging box 9 into the chute to adapt to the rhythm of high-speed production.

[0034] As shown in Figure 5 , the output section 7 can directly adopt a conveying device to receive the standing packaging box 9 and drive the packaging box 9 to move. The output section 7 can also adopt the following structure: The output section 7 includes conveying parts 71 and a third conveying line 72 arranged in parallel, and a second pushing part 73. The conveying part 71 is located at the discharge port of the guide part 62, and is used to receive the standing packaging box 9 and arrange multiple packaging boxes 9 in a group on it. The second pushing part 73 is used to push a group of packaging boxes 9 arranged in a group on the conveying part 71 to the third conveying line 72 in a group, so that the packaging boxes 9 on the third conveying line 72 are arranged in a group. The third conveying line 72 is used to receive a group of packaging boxes 9 conveyed from the third conveying line 72 and drive the packaging boxes 9 into the disposal section 8.

[0035] Specifically, the conveying part 71 and the third conveying line 72 have the same structure, both including a body of a belt conveying structure, and multiple partitions are arranged on the belt of the body in a group. The adjacent two partitions have a space, which is used to accommodate a standing packaging box 9. The packaging box 9 overturned from the guide part 62 enters the adjacent space in sequence, so as to arrange multiple packaging boxes 9 in a group. The second pushing part 73 includes a linear moving unit and multiple push teeth. Each push tooth corresponds to each packaging box 9 in each group of packaging boxes 9. The linear moving unit pushes multiple packaging boxes 9 into the third conveying line 72 through the push teeth at one time.

[0036] Preferably, the linear moving unit can be a linear moving guide rail, an electric telescopic rod, or a pneumatic telescopic cylinder, etc. The linear moving unit is arranged above the conveying part 71 and the third conveying line 72 through a mounting frame, and pushes the packaging box 9 to move from above.

[0037] Preferably, the feeding conveying section 1, the discharging conveying section 5, and the output section 7 in the present application all drive the packaging box 9 to move through a conveying belt structure.

[0038] As shown in Figure 1 , Figure 5As shown, the processing section 8 includes a defective product receiving area and a good product receiving area. The packaging box 9 passes through the defective product receiving area and the good product receiving area in one go. The corresponding defective products are kicked out of the output section 7 and enter the defective product receiving area, while the good products enter the good product receiving area.

[0039] like Figure 5 As shown, the defective product receiving area includes: The waste removal mechanism 81 includes multiple independent pushing units. The packaging boxes 9 are transported to the waste removal mechanism 81 in a group of multiple units, and each group of multiple pushing units corresponds to one of the multiple pushing units. Waste support plate 82 is used to support the defective product packaging box 9 kicked out by the waste kicking mechanism 81; The first pushing component 83 is used to push the packaging boxes 9 that have entered the waste bearing plate 82 to move in the first direction and arrange them into a row; The second pushing component 84 is used to push the packaging boxes 9 arranged in a row to move in a second direction for secondary arrangement into a neat side, wherein the first direction is parallel to the conveyor line and the second direction is perpendicular to the first direction.

[0040] During operation, the number of pushing units corresponds one-to-one with the number of packaging boxes 9 in each group of packaging boxes 9. When a defective product is detected in a certain packaging box, the corresponding pushing unit moves independently. This greatly reduces the working cycle time of scrap removal. Whether it is one defective product or multiple defective products, the working cycle time is consistent, which greatly improves the working efficiency of the scrap removal mechanism 81 and can better adapt to the pace of high-speed production.

[0041] The good product receiving area includes: The good product pushing mechanism 86 is used to push the packaging box 9 of the good product on the output section 7 onto the good product carrier plate 85; The good product carrier plate 85 is located on one side of the output section 7 and is used to carry the good product packaging box 9; The fourth pushing component 87 is used to push the good product packaging boxes 9 that have entered the good product carrier plate 85 to move in the first direction and arrange them into a row; The fifth pushing component 88 is used to push the neatly arranged good product packaging boxes 9 in a row to move in the second direction for secondary straightening and arranging them into a neat side, wherein the first direction is parallel to the conveyor line and the second direction is perpendicular to the first direction.

[0042] The first pushing component 83, the second pushing component 84, the fourth pushing component 87 and the fifth pushing component 88 all comprise a telescopic component and a pushing plate arranged at the end of the telescopic component, and the telescopic component drives the corresponding pushing plate to move. The telescopic component can be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod in the prior art. The good product pushing mechanism 86 also comprises the telescopic component, and a vertical plate corresponding to the number and position of each packaging box 9 is arranged at the telescopic end of the telescopic component, and each vertical plate pushes the packaging box 9 to move from the output section 7 to the carrying plate.

[0043] Preferably, a brush 89 is arranged above the good product carrying plate 85, and the bristles of the brush 89 are used to contact the top of the packaging box 9 when the good product pushing mechanism 86, the fourth pushing component 87 and the fifth pushing component 88 push the corresponding good product packaging box 9 to move.

[0044] More preferably, a brush 89 is also arranged on the waste carrying plate 82, and the bristles of the brush 89 are used to contact the top of the packaging box 9 when the pushing unit, the first pushing component 83 and the second pushing component 84 push the corresponding defective product packaging box 9 to move.

[0045] In the present application, the arrangement of the brush 89 makes the standing packaging box 9 not easy to fall down and more stable in posture when moving and stopping.

[0046] In the prior art, a single detection group is usually arranged on each face of the packaging box 9 to take a picture only once. However, in practice, the types of defects on the packaging box 9 are various, and limited by the cost, the detection of each face is carried out by using a forward detection method: common defects of the packaging box 9 are first photographed and learned, and then classified into a sample database. When a face of the packaging box 9 is photographed, the features are compared with the learned samples in the sample database, and if they are consistent, the packaging box 9 is judged as a defective product. This way has certain difficulty in the accuracy of identification and the difficulty of algorithm expansion.

[0047] Therefore, as shown in Figure 6 , Figure 7 The present application also discloses a batch six-face detection process using the batch six-face detection equipment, and each face of the packaging box 9 is detected at least twice by multiple detection groups, so that various forms of sampling are facilitated, and various algorithm fusion modes are developed to identify various defects of the packaging box 9.

[0048] The multiple detection groups are arranged in the following manner, including: The first detection group 11 comprises three visual imagers which are distributed on the left and right sides and above the feeding conveying section 1 to detect the left side 91, the right side 92 and the front face of the packaging box 9 once; The second detection group 23 comprises multiple visual imagers, which are distributed above the multiple first conveying lines 21, and are used for performing secondary detection on the front face 93 of the packaging box 9; The third detection group 32 comprises multiple visual imagers, which are distributed above the multiple first turnover mechanisms 3, and are used for performing secondary detection on the left side face 92 of the packaging box 9 when the first turnover mechanism 3 drives the packaging box 9 to turn over to the vertical posture; The fourth detection group 43 comprises multiple visual imagers, which are distributed above the multiple second conveying lines 41, and are used for performing primary detection on the back face 94 of the packaging box 9; The fifth detection group 51 comprises one visual imager, which is distributed above the unloading conveying section 5, and is used for performing secondary detection on the back face 94 of the packaging box 9; The sixth detection group 74 comprises three visual imagers, which are distributed on the left and right sides of the conveying direction of the third conveying line 72 and above the third conveying line 72, and are used for performing primary detection on the front and back side faces of the packaging box 9 and secondary detection on the right side face of the packaging box 9; The seventh detection group 75 comprises two visual imagers, which are distributed on the left and right sides of the conveying direction of the third conveying line 72, and are used for performing secondary detection on the front side face 95 and the back side face 96 of the packaging box 9 after the detection of the sixth detection group 74.

[0049] Compared with the existing scheme of single-time photographing and defect recognition for each face, the scheme of twice detection of the six side faces of the packaging box 9 by multiple detection groups has the following advantages: 1. When detecting in large quantities, the probability of false detection and missed detection is reduced, and the detection quality is improved; 2. Multiple photographing times for each face can classify and arrange different defects of each face, which is more conducive to visual training, and the algorithm has expansion space and is more accurate in recognition; 3. Group photographing is adopted during secondary detection, and the abnormality of a certain box is particularly obvious in a group, and the recognition algorithm is simpler and more efficient, and does not need frequent training and complex database.

[0050] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0051] In addition, if the description of "first", "second" and the like is involved in the embodiments of the present application, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.
