[0016] Step S1024: determine that the category is abnormal.

[0017] As a further improvement of the present invention, in step S102, the step of inspecting the unpacking status of the material based on the real-time image information and the pre-stored material image is specifically as follows:

[0018] Step S1025: Acquire images of irregularly unpacked materials, and pre-store the images of irregularly unpacked materials in an information database to form pre-stored material images.

[0019] Step S1026, comparing the acquired real-time image of the material with the pre-stored material image of the corresponding material in the information database;

[0020] Step S1027: When the similarity between the real-time material image and the pre-stored material image reaches a set value, it is determined to be unqualified unpacking; when the similarity between the real-time material image and the pre-stored material image does not reach the set value, it is determined to be qualified unpacking.

[0035] If the real-time area is smaller than the estimated area, it is judged that there is a phenomenon of pressure;

[0038] Control the front track to continue conveying at normal speed;

[0039] Reduce the speed of the rear track to increase the distance between the two materials.

[0040] As a further improvement of the present invention, the method of controlling the front track to continue conveying at normal speed and reducing the speed of the rear track is as follows:

[0055] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0056] like Figure 1-7 , a method for disinfecting materials transferred in an intelligent clean workshop, comprising the following steps:

[0057] Step S101: remove the outer packaging of the material and attach the corresponding material label;

[0058] Step S102: Identify the material label, obtain a real-time image of the material, obtain a corresponding pre-stored material image in the information library based on the material label, and inspect the unpacking status of the material based on the real-time image and the pre-stored material image;

[0059] Step S103: Obtain the real-time height of the material, obtain the pre-stored height corresponding to the material in the information library according to the material tag, detect whether there is stacked material based on the pre-stored height and the real-time height of the material, and adjust the stacked material;

[0060] Step S104: Calculate the real-time area of ​​the two materials based on their areas and the distance between them. Identify the material labels of the two adjacent materials, and calculate an estimated area based on the material labels and the preset minimum distance between the materials. Compare the estimated area with the real-time area to determine if there is any pressing, and adjust the situation accordingly.

[0061] Step S105: sterilize the material.

[0062] The present invention proposes a disinfection method for transferring materials in an intelligent clean workshop. By comparing the appearance characteristics of the materials, it is ensured that the material category is correct and the outer packaging of the materials has been completely removed; by detecting whether the materials are stacked, the stacked materials are adjusted to avoid the phenomenon that the materials cannot be disinfected due to stacking, thereby ensuring the disinfection effect; by detecting whether the materials are pressed, the pressed materials are adjusted to eliminate the pressing of the materials, thereby ensuring the disinfection effect.

[0063] Avoid incomplete unpacking, stacking, or pressing of materials that may lead to poor disinfection effects, and ensure effective disinfection of materials.

[0064] In this embodiment, an unpacking area 1 is provided, in which the outer packaging of the materials is removed and labels corresponding to the materials are affixed.

[0065] In this embodiment, a connecting track 2 and a first detection area 3 are also provided. The unpacking area 1 is connected to the first detection area 3 through the connecting track, and the exit end of the first detection area 3 is connected to a return track 4 and a transfer track 5, and the other end of the return track is connected to the unpacking area.

[0066] In step S102, identifying the material label further includes the following steps:

[0067] Step S1021, obtaining the material category information by identifying the material tag;

[0068] Step S1022: Obtain the BOM table and check whether the BOM table contains the category information of the material;

[0069] If yes, go to step S1023, if not, go to step S1024;

[0070] Step S1023: determine that the material category is normal;

[0071] Step S1024: determine that the material category is abnormal.

[0072] In step S1022, when the product formula is adjusted, a new formula BOM table needs to be entered into the system to ensure that the transferred materials meet the category requirements of the new formula.

[0073] In step S1023, if the material category is normal, the material label is not affixed incorrectly. In step S1024, if the material category is abnormal, it means the material label is affixed incorrectly. The labels of the transferred materials are inspected to avoid affixing incorrect material labels on the materials, which may affect subsequent operations.

[0074] In step S102, the steps of inspecting the unpacking status of the material based on the real-time image information and the pre-stored material image are as follows:

[0075] Step S1025: Acquire images of irregularly unpacked materials, and pre-store the images of irregularly unpacked materials in an information database to form pre-stored material images.

[0076] Step S1026, comparing the acquired real-time image of the material with the pre-stored material image of the corresponding material in the information database;

[0077] Step S1027: When the similarity between the real-time material image and the pre-stored material image reaches a set value, it is determined to be unqualified unpacking; when the similarity between the real-time material image and the pre-stored material image does not reach the set value, it is determined to be qualified unpacking.

[0078] In step S1025 , the various types of images of irregular unpacking include images of materials containing paper scraps, images of materials with broken inner packaging, images of materials with dirty inner packaging, and the like.

[0079] In step S1027, the set value is 90%±5%. That is, when the set value is 90%, when the similarity between the real-time image of the material and the pre-stored material image reaches 90%, it is determined to be unqualified unpacking.

[0080] In this embodiment, before the system is used, various unqualified unpacking scenarios (including paper scraps, damaged inner packaging, incorrect labeling, and dirty inner packaging) are simulated; qualified unpacking scenarios; and unpacking scenarios that are on the verge of being qualified or unqualified are simulated to train the system. The system then obtains various photos and enters them into the system database.

[0081] During daily operation, if the system detects that a conveyed material's similarity to one of the categories exceeds 90%, it automatically classifies the material as such and categorizes it into acceptable unpacking (automatically transferred), unacceptable unpacking (information feedback and automatic disposal), or critical status (system shutdown and manual confirmation). If the critical status is manually confirmed as acceptable, the image is automatically transferred to the acceptable unpacking image library; if the image is manually confirmed as unacceptable, it is automatically transferred to the unacceptable image library. Through daily dynamic training, the system memorizes and accurately judges various statuses.

[0082] After the product is judged to be abnormal or unqualified, the following steps are also included:

[0083] The materials are returned to the unpacking area via the return track for relabeling or re-unpacking.

[0084] When abnormal material category and unqualified unpacking are detected in the first inspection area, the material is returned to the unpacking area through the return track, and the material is re-labeled and / or unpacked again; when the material is inspected in the first inspection area and the material category is normal and the unpacking is qualified, the material is transported to the transfer track for further transmission.

[0085] In step S103, the steps of detecting whether there is stacked material according to the pre-stored height and the real-time height of the material are specifically as follows:

[0086] Step S1031, obtaining the real-time height of the material;

[0087] Step S1032: Identify the material tag and obtain the corresponding pre-stored height in the information library according to the material tag;

[0088] Step S1033: If the real-time height is equal to the pre-stored height, it is determined that there is no material stacking;

[0089] Step S1034: If the real-time height is greater than the pre-stored height, it is determined that the material is stacked.

[0090] In step S1031, a second detection area 51 is provided on the transfer track, and the real-time height of the material is detected in the second detection area by image detection, and whether the material is stacked in the second detection area is detected.

[0091] In steps S1033 and S1034, the pre-stored height is the sum of the standard height and the deviation height of the material. If the real-time height is equal to the pre-stored height, it means that the real-time height is within the deviation range of the standard height; if the real-time height is greater than the pre-stored height, it means that the real-time height is greater than the standard height and exceeds the allowable deviation range.

[0092] The standard material height is 10cm, with a 1cm deviation, meaning the pre-set height is 9-11cm. If the actual height is 10.2cm, since 10.2cm is within the 9-11cm range, the actual height is considered equal to the pre-set height and, therefore, the material is not stacked. If the actual height is 12.1cm, since 12.1cm is not within the 9-11cm range, the actual height is considered greater than the pre-set height, indicating that the material is stacked.

[0093] In step S103, the steps of adjusting the stacked materials are specifically as follows:

[0094] Step S1035, sucking up the stacked materials using the suction cup;

[0095] Step S1036: Controlling the rear track to suspend delivery or slowing down the conveying speed of the rear track to form a placement space on the track, and placing the stacked materials in the placement space;

[0096] Step S1037: Control the track to continue conveying materials at a preset conveying speed.

[0097] A second adjustment area 52 is provided on the transfer track. The second adjustment area 52 is connected to the second detection area 51 . A suction cup is provided at the second adjustment area 52 . The stacking phenomenon can be adjusted in the second adjustment area.

[0098] A first adjustment track and a second adjustment track are provided at the second adjustment area, and the first adjustment track is at the front end of the second adjustment track, that is, the second adjustment track is at an end close to the second detection area.

[0099] In step S1035, when it is confirmed that the material is stacked, the stacking material is sucked up from the stacked material by the suction cup;

[0100] In step S1036, the conveying of the second adjustment track is paused or the conveying speed of the second adjustment track is slowed down, and the first adjustment track is controlled to continue conveying at a normal conveying speed, so as to form a placement space between the stacking material and the stacked material, and the stacked material sucked by the suction cup is placed in the placement space;

[0101] In step S1037, after the adjustment is completed, the second adjustment track and the first adjustment track are controlled to continue to transport the material at a normal transmission speed.

[0102] In this embodiment, a third detection area 53 and a third adjustment area 54 are also included. The third detection area 53 is connected to the second adjustment area 54, and the third adjustment area is connected to the third detection area. In the third detection area, it is detected whether the material is pressed, and the pressing phenomenon can be adjusted in the third adjustment area.

[0103] In step S104, the steps of detecting whether there is a pressing phenomenon based on the comparison between the estimated area and the real-time area are as follows:

[0104] Step S1041: When the inspected material arrives at the inspection point, the area of ​​the inspected material is obtained as the first real-time area, the area of ​​the material behind the inspected material is obtained as the second real-time area, the area of ​​the distance between the two materials is obtained as the third real-time area, and the sum of the first real-time area, the second real-time area and the third real-time area is obtained as the real-time area;

[0105] Step S1042: Identify the label of the inspected material and the label of the material behind the inspected material, obtain the pre-stored area of ​​the inspected material in the information library as the first pre-stored area, obtain the area of ​​the material behind the inspected material in the information library as the second pre-stored area, and the preset minimum material spacing area between the two materials as the third pre-stored area. The sum of the first pre-stored area, the second pre-stored area, and the third pre-stored area is the estimated area;

[0106] Step S1043: If the real-time area is smaller than the estimated area, it is determined that there is a pressing phenomenon;

[0107] In step S1044 , if the real-time area is greater than or equal to the estimated area, it is determined that there is no pressing phenomenon.

[0108] In step S1042, an appropriate minimum material spacing can be selected based on actual conditions. The minimum material spacing is typically 3-10 cm. In this embodiment, the minimum material spacing is 5 cm. The third pre-stored area is the product of the minimum material spacing and the width of the smaller material.

[0109] In step S1041, if there are materials A and B, material A is in front of material B, and the width of material A in a top-down view is greater than the width of material B in a top-down view. When material A reaches the detection point, the top-down area of ​​material A is obtained as the first real-time area, the top-down area of ​​material B is obtained as the second real-time area, and the product of the distance between materials A and B and the width of material B is the third real-time area. The sum of the first real-time area, the second real-time area, and the third real-time area is the real-time area.

[0110] Step S1045, the steps of adjusting the pressing phenomenon are specifically as follows:

[0111] Step S1046, controlling the front track to continue conveying at a normal speed and reducing the speed of the rear track to increase the distance between the two materials.

[0112] In step S1046, the method of controlling the front track to continue to transport at normal speed and reducing the speed of the rear track is as follows:

[0113] In the detection area, whether there is a pressing phenomenon is detected, and the detection area includes a first conveying track, a second conveying track and a third conveying track, and the first conveying track is at a front position, the third conveying track is at a rear position, and the second conveying track is between the first conveying track and the third conveying track;

[0114] When it is determined that there is a pressing phenomenon, the first conveying track is controlled to run at a first speed; the second conveying track is controlled to run at a second speed; the third conveying track is controlled to run at a third speed; and the second speed is lower than the first speed, and the third speed is lower than the second speed.

[0115] In this embodiment, a first conveying track, a second conveying track and a third conveying track are provided in the third adjustment area.

[0116] When a pressing phenomenon occurs, the second and third conveyor tracks are controlled to reduce their running speeds, and the transmission of the second detection zone, the second adjustment zone, the third detection zone, and the connecting track is suspended. In other words, the material transmission of the rear track is suspended. This ensures that the distance between the materials pressing against each other is increased, forming a placement position between the two materials, while preventing the rear material from pressing against each other.

[0117] In step S105, the steps of sterilizing the material are specifically as follows:

[0118] The disinfection dose is controlled by controlling the irradiation intensity and irradiation time, and the disinfection dose is controlled to be greater than or equal to the preset dose.

[0119] In this embodiment, a virus-killing chamber is further included. A virus-killing conveying track is provided in the virus-killing chamber, and the material passes through the virus-killing chamber via the virus-killing conveying track.

[0120] Two photoelectric sensing probes are installed on the material transfer track. The system calculates the material transfer speed based on the time it takes for the items to reach the two probes. When the speed exceeds the set upper limit, the system automatically provides feedback and reduces the track's operating speed.

[0121] In this embodiment, the preset dose is 20000 μW / cm 2The disinfection dose K is equal to the product of the irradiation intensity I and the irradiation time T, that is, K = I × T.

[0122] Control the disinfection dose to be greater than or equal to the preset dose to effectively ensure the disinfection effect. The preset dose is 40μW / cm 2 If the preset dose of UV lamp is less than 40μW / cm 2 , the UV lamp needs to be replaced.

[0123] In this embodiment, an ultraviolet lamp intensity irradiator is placed at a specific position on the material transmission track to detect the irradiation intensity at regular intervals, and the disinfection dosage is controlled in accordance with the detected irradiation intensity and the transmission speed of the track.

[0124] Within the disinfection chamber, ultraviolet lamps are located on the front, rear, left, right, upper, and lower walls of the chamber to effectively disinfect all six surfaces of the material. In this embodiment, two ultraviolet lamps are located on each of the front, rear, left, right, and upper walls, and four are located on the lower wall.

[0125] In this embodiment, the diameter of the rotating shaft is d, and the gap between adjacent rotating shafts is a. The ratio of d to a is reasonably set, and d / a is controlled to be greater than 1 / 1.5.

[0126] After being disinfected in the disinfection chamber, the materials can be transported to the clean area via the track.

[0127] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
