Technical Field

[0001] This application belongs to the field of tobacco automation control technology, and specifically relates to a method and system for sealing control of transparent film for cigar carton. Background Technology

[0002] Cigar boxes generally refer to packaging boxes used to store cigars. These boxes are often exquisitely designed, combining practicality and aesthetics.

[0003] In actual production applications, the packaging of transparent film for carton boxes is mainly done manually, which not only has high labor costs, but also cannot effectively guarantee the packaging effect and efficiency of the transparent film for carton boxes. Summary of the Invention

[0004] This application addresses the aforementioned technical problems of high labor costs and ineffective packaging quality and efficiency associated with manually applying transparent film to cigar carton boxes. It proposes a method and system for controlling the packaging of transparent film on cigar carton boxes, the technical solution of which is as follows:

[0005] In a first aspect, embodiments of this application provide a method for controlling the sealing of a transparent film for a cigar carton, comprising:

[0006] When the nth packaging box is in the designated position, the control pusher mechanism pushes the nth packaging box according to the preset path. When the nth packaging box is detected to be in the inner cavity of the corresponding first transparent film, the pusher mechanism pushes the nth packaging box film composed of the nth packaging box and the first transparent film.

[0007] When the nth encapsulation box film is in the folding position corresponding to the folding mechanism, the folding mechanism is controlled to fold the nth encapsulation box film, and the first sealing mechanism is controlled to seal the nth encapsulation box film after the folding process.

[0008] Obtain the distance between the (n+1)th encapsulation film and the nth encapsulation film after heat sealing. When the distance is detected to be within a preset distance range, control the corner folding mechanism to fold the nth encapsulation film after heat sealing, and control the second heat sealing mechanism to heat seal the nth encapsulation film after the corner folding.

[0009] In one alternative to the first aspect, before the nth box is in the specified position, it further includes:

[0010] Based on the size parameters of the nth packaging box, the cutting area is determined on the transparent film to be processed, and the cutting area and the opening pull line are glued together.

[0011] The control film cutting mechanism cuts the cutting area containing the opening pull line to obtain a first transparent film, and performs a pressing process on the first transparent film based on a preset mold to form an inner cavity in the first transparent film;

[0012] The control film feeding mechanism moves the first transparent film, after the pressing process, to the preset path corresponding to the pushing mechanism.

[0013] In another alternative to the first aspect, after the film-cutting mechanism cuts the cutting area containing the opening pull wire to obtain the first transparent film, the method further includes:

[0014] When a broken pull cord is detected on the first transparent film, a pull cord breakage warning signal is issued, and the film feeding mechanism is controlled to move the first transparent film to the recycling position.

[0015] In yet another alternative to the first aspect, before detecting that the nth package is inside the cavity of the corresponding first transparent film, the method further includes:

[0016] Acquire a first image containing the nth packaging box and the first transparent film at a preset time interval, and identify the outline features of the packaging box and the outline features of the transparent film from each first image;

[0017] The overlapping area is calculated based on the outline features of the packaging box and the outline features of the transparent film. When the overlapping area is detected to be consistent with the area of ​​the packaging box corresponding to the nth packaging box, it is determined that the nth packaging box is located in the inner cavity of the corresponding first transparent film.

[0018] The film feeding mechanism is controlled to return to the initial position. After pressing the second transparent film corresponding to the (n+1)th packaging box based on the preset mold, the film feeding mechanism is controlled to move the pressed second transparent film from the initial position to the preset path corresponding to the pusher mechanism.

[0019] In another alternative to the first aspect, before the nth box is in the specified position, it further includes:

[0020] When the first transparent film after the pressing process is on the preset path corresponding to the pushing mechanism, at least two marking points on the first transparent film are identified.

[0021] Obtain the angle between the line connecting any two adjacent marker points and the calibration line corresponding to the preset path;

[0022] When it is determined that the angle between the line connecting any two adjacent marker points and the calibration line is not a preset angle, the film feeding mechanism is controlled to perform correction processing on the first transparent film based on the difference between the angle and the preset angle.

[0023] In another alternative embodiment of the first aspect, before controlling the first sealing mechanism to seal the nth encapsulation film after the edge folding process, the method further includes:

[0024] Acquire at least two second images containing the side of the nth encapsulation box film after edge folding, and identify transparent film contour feature points from each second image;

[0025] When the number of transparent film contour feature points corresponding to any second image is inconsistent with the number of transparent film contour feature points corresponding to other second images, abnormal feature points are selected from the transparent film contour feature points, and the sealing path is determined based on the abnormal feature points.

[0026] Controlling the first sealing mechanism to seal the nth packaging film after edge folding includes:

[0027] The first sealing mechanism is controlled to seal the nth packaging film after the edge folding process according to the sealing path.

[0028] In another alternative embodiment of the first aspect, after the pushing mechanism pushes the nth packaging box film, which consists of the nth packaging box and the first transparent film, the method further includes:

[0029] When the cylinder pressure value corresponding to the pushing mechanism is detected to be outside the preset pressure range, the pushing mechanism is controlled to stop pushing the nth encapsulation box film and a box jam warning signal is issued.

[0030] Secondly, embodiments of this application provide a sealing control system for a transparent film on a cigar carton, comprising:

[0031] The first processing module is used to control the pushing mechanism to push the nth packaging box according to a preset path when the nth packaging box is in a specified position, and when the nth packaging box is detected to be in the inner cavity of the corresponding first transparent film, the pushing mechanism pushes the nth packaging box film composed of the nth packaging box and the first transparent film.

[0032] The second processing module is used to control the folding mechanism to fold the nth packaging film when the nth packaging film is in the folding position corresponding to the folding mechanism, and to control the first sealing mechanism to seal the nth packaging film after the folding process.

[0033] The third processing module is used to obtain the distance between the (n+1)th encapsulation film and the nth encapsulation film after heat sealing, and when the distance is detected to be within a preset distance range, it controls the corner folding mechanism to perform corner folding on the nth encapsulation film after heat sealing, and controls the second heat sealing mechanism to perform heat sealing on the nth encapsulation film after corner folding.

[0034] Thirdly, embodiments of this application also provide a packaging control system for a transparent film for cigar carton boxes, including a processor and a memory;

[0035] The processor is connected to the memory;

[0036] Memory, used to store executable program code;

[0037] The processor runs a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to implement the encapsulation control method for the transparent film of cigar carton provided by the first aspect or any implementation of the first aspect of the embodiments of this application.

[0038] Fourthly, embodiments of this application provide a computer storage medium storing a computer program, which includes program instructions. When executed by a processor, the program instructions can implement the encapsulation control method for the transparent film of a cigar box provided by the first aspect or any implementation thereof of the embodiments of this application.

[0039] In this embodiment, when sealing the transparent film of a cigar carton, when the nth packaging box is in a designated position, the pushing mechanism is controlled to push the nth packaging box according to a preset path. When the nth packaging box is detected to be in the inner cavity of the corresponding first transparent film, the pushing mechanism pushes the nth packaging box film composed of the nth packaging box and the first transparent film. When the nth packaging box film is in the folding position corresponding to the folding mechanism, the folding mechanism is controlled to fold the nth packaging box film, and the first sealing mechanism is controlled to seal the nth packaging box film after the folding. The distance between the (n+1)th packaging box film and the nth packaging box film after the sealing is obtained. When the distance is detected to be within a preset distance range, the corner folding mechanism is controlled to fold the nth packaging box film after the sealing is performed, and the second sealing mechanism is controlled to seal the nth packaging box film after the corner folding is performed. By performing real-time positioning detection on packaging boxes that require transparent film encapsulation, and using an automatic control program to control the feeding mechanism, folding mechanism, first sealing mechanism, corner folding mechanism, and second sealing mechanism, the packaging box and the corresponding transparent film are encapsulated. This not only effectively avoids the cost losses caused by manual labor, but also greatly improves the overall encapsulation efficiency while enhancing the aesthetics of the transparent film encapsulation, combined with the automatic control program.

Furthermore, features described with respect to some examples may be combined into other examples.

[0049] Please see Figure 1 , Figure 1 The diagram shows an overall flowchart of a packaging control method for a transparent film for cigar carton provided in an embodiment of this application.

[0050] like Figure 1 As shown, the sealing control method for the transparent film of a cigar box may include at least the following steps:

[0051] Step 102: When the nth packaging box is in the designated position, the pusher mechanism is controlled to push the nth packaging box according to the preset path. When the nth packaging box is detected to be in the inner cavity of the corresponding first transparent film, the pusher mechanism pushes the nth packaging box film composed of the nth packaging box and the first transparent film.

[0052] In this embodiment, the packaging control method for the transparent film of cigar carton can be, but is not limited to, applied to a control terminal (or programmable logic controller, PLC) capable of controlling the transparent film packaging production line. This control terminal (or PLC using an automatic control program) controls multiple mechanisms on the transparent film packaging production line to achieve the packaging process of cigar (or cigarette) boxes and their corresponding transparent films. The transparent film packaging production line can at least include a pushing mechanism for pushing the cigar (or cigarette) boxes, a folding mechanism for folding the edges of the packaging film composed of the boxes and the corresponding transparent films, a first sealing mechanism for sealing the long side of the folded packaging film, a cornering mechanism for folding the corners of the folded packaging film, and a second sealing mechanism for sealing the left and right sides of the folded packaging film. The pushing mechanism can be, but is not limited to, a... The system includes a conveying device for supporting the packaging box and its corresponding transparent film, and a cylinder pushing device for pushing the packaging box or the encapsulation film composed of the packaging box and its corresponding transparent film along a preset path. The number of cylinder pushing devices can be multiple, so that multiple packaging boxes or encapsulation films composed of multiple packaging boxes and their corresponding transparent films can be pushed simultaneously on the conveying device. The folding mechanism may include, but is not limited to, an upper folding plate folding device and a lower folding plate folding device, so that the lower folding plate folding device folds the side of the encapsulation film along its long side upwards. The first sealing mechanism can, but is not limited to, sealing the side of the long side of the packaging box film by controlling the sealing plate to perform the sealing treatment. The corner folding mechanism can, but is not limited to, a device consisting of a film folding plate and a corner folder, to form a corner by creating creases on the transparent film through the film folding plate and the corner folder. The second sealing mechanism can, but is not limited to, sealing the left and right sides of the packaging box film after corner treatment by controlling the sealing plate. In this embodiment, it can also, but is not limited to, performing spot heat treatment on each side of the sealed packaging box film by spot heat treatment equipment to make the sealing effect of the transparent film more secure. It can also perform top and bottom shaping and sealing treatment and front and back beautifying sealing treatment on the packaged box film after spot heat treatment by other sealing and packaging equipment to make the sealing effect of the transparent film of the box more beautiful.

[0053] It should be noted that the aforementioned pushing mechanism, folding mechanism, first sealing mechanism, corner folding mechanism, and second sealing mechanism are all standard process equipment in the packaging box transparent film packaging production line. Their specific structures and working principles are all standard technical means in this field and will not be elaborated further. In actual production applications, various types of mechanisms (or other packaging equipment) are mainly operated manually by multiple operators, which not only results in high labor costs but also fails to effectively guarantee the packaging effect and efficiency of the packaging box transparent film.

[0054] Understandably, when the control terminal is sealing the transparent film of the cigar carton, it performs real-time positioning detection on the packaging box that needs to be sealed with the transparent film. The automatic control program controls the pushing mechanism, the folding mechanism, the first sealing mechanism, the corner folding mechanism, and the second sealing mechanism to seal the packaging box and the corresponding transparent film. This not only effectively avoids the cost loss caused by manual labor, but also greatly improves the overall sealing efficiency while improving the aesthetics of the transparent film sealing.

[0055] Of course, you can also refer to this section. Figure 2 The diagram shown illustrates a terminal architecture of a packaging control method for a transparent film on a cigar carton, according to an embodiment of this application. Figure 2 As shown, the packaging control method for transparent film of cigar carton can be applied to a control terminal for controlling the packaging production line of transparent film of carton. The control terminal may specifically include a pushing mechanism for pushing the packaging box of cigars (or cigarettes), a folding mechanism for folding the edges of the packaging film composed of the packaging box and the corresponding transparent film, a first sealing mechanism for sealing the long side of the sealed packaging film after edge treatment, a corner folding mechanism for folding the corner of the sealed packaging film after long side sealing, a second sealing mechanism for sealing the left and right sides of the sealed packaging film after corner treatment, a film cutting mechanism for cutting the transparent film, and a film feeding mechanism for moving the cut transparent film. The film cutting mechanism and the film feeding mechanism are also conventional process equipment in the packaging transparent film packaging production line. Their specific structure and working principle are conventional technical means in this field and will not be described in detail.

[0056] Specifically, when sealing cigar cartons with transparent film, the control terminal can, but is not limited to, using a photoelectric detection device to detect a designated position on the transparent film sealing production line in real time to determine whether the designated position contains the nth cigar (or cigarette) box to be sealed with transparent film. Here, the photoelectric detection device can, but is not limited to, a photoelectric sensor. The control terminal analyzes and processes the signal collected by the photoelectric sensor to determine whether the designated position contains the nth cigar (or cigarette) box. It is understood that, in this embodiment, each box can, but is not limited to, be moved sequentially to the designated position at certain time intervals using a movable clamping and transporting device, and each box can be obtained by other process equipment packaging cigars (or cigarettes). Here, n is a positive integer, for example, but not limited to 1, 2, 3..., and its maximum value is consistent with the total number of boxes corresponding to the transparent film sealing production line.

[0057] Furthermore, when the nth packaging box is detected to be in a designated position, the control terminal can control the pushing mechanism to push the nth packaging box in the designated position according to a preset path. During the pushing process, the nth packaging box will come into contact with the transparent film (i.e., the first transparent film) on the preset path, and the nth packaging box can be placed inside the cavity of the transparent film under the action of the pushing force. The pushing mechanism then pushes the packaging film composed of the nth packaging box and the transparent film. Here, the transparent film corresponding to the nth packaging box can be, but is not limited to, moved to the preset path by a film feeding mechanism or other movable transport equipment. The film feeding mechanism can fix the transparent film on or above the preset path by adsorption, so that the suction force applied to the transparent film stops when the packaging box is inside the cavity of the transparent film, thereby realizing the pushing mechanism pushing the packaging film composed of the nth packaging box and the transparent film.

[0058] It is understood that, in order to ensure a better transparent film encapsulation effect in the embodiments of this application, the volume or size of the inner cavity of the transparent film is larger than the volume or size of the corresponding packaging box, so that the packaging box can smoothly enter the inner cavity of the transparent film under the pushing action, and the opening direction of the inner cavity of the transparent film can be oriented towards the moving direction of the packaging box.

[0059] It should be noted that when the nth packaging box leaves the designated position, the photoelectric detection device can continue to detect the designated position to determine whether the (n+1)th packaging box is in the designated position. When it is determined that the (n+1)th packaging box is in the designated position, the control terminal can continue to send a pushing command to the pushing mechanism to control the pushing mechanism to push the (n+1)th packaging box in the designated position according to the preset path until the pushing of all packaging items is completed.

[0060] As an optional embodiment of this application, before the nth packaging box is in the designated position, the method further includes:

[0061] Based on the size parameters of the nth packaging box, the cutting area is determined on the transparent film to be processed, and the cutting area and the opening pull line are glued together.

[0062] The control film cutting mechanism cuts the cutting area containing the opening pull line to obtain a first transparent film, and performs a pressing process on the first transparent film based on a preset mold to form an inner cavity in the first transparent film;

[0063] The control film feeding mechanism moves the first transparent film, after the pressing process, to the preset path corresponding to the pushing mechanism.

[0064] Specifically, to ensure better sealing and opening effects of the transparent film, before the nth packaging box is in the designated position, the control terminal can, but is not limited to, determine the inner cavity size parameters of the corresponding transparent film based on the size parameters of the nth packaging box, and draw the shape of the transparent film corresponding to the unfolded planar structure of the inner cavity based on the inner cavity size parameters. Furthermore, the area on the transparent film to be processed that matches the shape of the transparent film can be used as the cutting area. Here, when determining the inner cavity size parameters of the corresponding transparent film based on the size parameters of the nth packaging box, taking the size parameters of the nth packaging box as length a, width b, and height c as an example, the inner cavity size parameters of the corresponding transparent film can be represented as length a*d, width b*d, and height c*d. Here, d can be understood as a preset coefficient, whose value range can be set between 1 and 1.5, and is not limited to this.

[0065] Next, after obtaining the cutting area, the control terminal can place the opening pull wire in the cutting area according to the preset pull wire position, so that the cutting area and the opening pull wire can be bonded by the guide roller, and the film cutting mechanism can be controlled to cut the cutting area containing the opening pull wire, that is, to cut along the edge of the cutting area containing the opening pull wire to obtain the first transparent film.

[0066] Next, after cutting out the first transparent film, the control terminal can also perform a pressing process on the first transparent film based on a preset mold, so that the first transparent film forms an inner cavity structure consistent with the aforementioned inner cavity size parameters. Here, the preset mold can be, but is not limited to, customized generation based on packaging boxes with different size parameters, and the size of the preset mold can be consistent with the aforementioned inner cavity size parameters.

[0067] Next, after obtaining the first transparent film with an inner cavity, the control terminal can also control the film feeding mechanism to adsorb the first transparent film with an inner cavity and move it to the preset path corresponding to the pushing mechanism.

[0068] As another optional embodiment of this application, after the film cutting mechanism cuts the cutting area containing the opening pull wire to obtain the first transparent film, the method further includes:

[0069] When a broken pull cord is detected on the first transparent film, a pull cord breakage warning signal is issued, and the film feeding mechanism is controlled to move the first transparent film to the recycling position.

[0070] Specifically, to determine whether the transparent film has a broken pull line after cutting, the control terminal, after obtaining the first transparent film, can also, but is not limited to, use a colorimeter or spectrophotometer to identify the surface of the first transparent film. This allows the color difference between the pull line and the transparent film to determine if the pull line is broken. Understandably, when a broken pull line is detected on the first transparent film, the control terminal can issue a pull line breakage warning signal to the operator, reminding them to adjust the film cutting mechanism promptly. Furthermore, to prevent transparent films with broken pull lines from entering the strip box transparent film packaging line, the control terminal can also control the film feeding mechanism to move the first transparent film with broken pull lines to the recycling position.

[0071] As another optional embodiment of this application, before the nth packaging box is in the designated position, it further includes:

[0072] When the first transparent film after the pressing process is on the preset path corresponding to the pushing mechanism, at least two marking points on the first transparent film are identified.

[0073] Obtain the angle between the line connecting any two adjacent marker points and the calibration line corresponding to the preset path;

[0074] When it is determined that the angle between the line connecting any two adjacent marker points and the calibration line is not a preset angle, the film feeding mechanism is controlled to perform correction processing on the first transparent film based on the difference between the angle and the preset angle.

[0075] Specifically, after the control film feeding mechanism places the first transparent film, after the pressing process, on the preset path corresponding to the pushing mechanism, the control terminal can also, but is not limited to, acquire an image containing the first transparent film after the pressing process using a top camera positioned above the preset path, and identify at least two marker points in the image. It is understood that each first transparent film can be pre-coated with at least two marker points, and each marker point can, but is not limited to, be arranged on the surface of the first transparent film in a specified order, with the distance between any two adjacent marker points being equal.

[0076] Next, after identifying at least two marker points in the image, the control terminal can connect any two adjacent marker points and calculate the angle between the connecting line and the calibration line corresponding to the preset path in the image. Here, the calibration line corresponding to the preset path can be understood as a calibration line parallel or perpendicular to the preset path. When the angle is detected to be different from the preset angle, it indicates that the first transparent film has a deviation angle relative to the preset path. Then, based on the difference between the angle and the preset angle, the film feeding mechanism can be controlled to rotate and correct the first transparent film along a specified rotation direction to make the angle the preset angle. The specified rotation direction can be, but is not limited to, clockwise or counterclockwise. It can be understood that when the angle is detected to be the preset angle, it indicates that the first transparent film has no deviation angle relative to the preset path, and then it is possible to detect whether the nth package is in the specified position.

[0077] In the embodiments of this application, the preset angle may be, but is not limited to, 0 degrees or 90 degrees, and the angle between the connecting line and the calibration line corresponding to the preset path is between 0 and 90 degrees.

[0078] As another optional embodiment of this application, before detecting that the nth packaging box is inside the cavity of the corresponding first transparent film, the method further includes:

[0079] Acquire a first image containing the nth packaging box and the first transparent film at a preset time interval, and identify the outline features of the packaging box and the outline features of the transparent film from each first image;

[0080] The overlapping area is calculated based on the outline features of the packaging box and the outline features of the transparent film. When the overlapping area is detected to be consistent with the area of ​​the packaging box corresponding to the nth packaging box, it is determined that the nth packaging box is located in the inner cavity of the corresponding first transparent film.

[0081] The film feeding mechanism is controlled to return to the initial position. After pressing the second transparent film corresponding to the (n+1)th packaging box based on the preset mold, the film feeding mechanism is controlled to move the pressed second transparent film from the initial position to the preset path corresponding to the pusher mechanism.

[0082] Specifically, to ensure the accuracy of detecting that the packaging box is within the cavity of the corresponding transparent film, the control terminal can acquire a first image containing the nth packaging box and the first transparent film at preset time intervals, and use image processing and other technologies to identify the outline features of the packaging box and the outline features of the transparent film from each first image. Here, the outline features of the packaging box can be understood as all feature points corresponding to the outline of the packaging box, or the outline lines connected by all feature points; the outline features of the transparent film can be understood as all feature points corresponding to the outline of the transparent film, or the outline lines connected by all feature points.

[0083] Next, after identifying the outline features of the packaging box and the transparent film, the control terminal can determine the area corresponding to the overlapping area based on the outline areas corresponding to the packaging box outline features and the transparent film outline features. When it is detected that the area corresponding to the overlapping area is the same as the area of ​​the nth packaging box, it indicates that the nth packaging box is already in the inner cavity of the corresponding transparent film. Thus, it can be determined that the nth packaging box is in the inner cavity of the corresponding first transparent film. At the same time, it is also necessary to control the film feeding mechanism to stop providing adsorption to the first transparent film, so as to effectively ensure that the pushing structure can push the packaging film composed of the packaging box and the first transparent film. It can also control the film feeding mechanism to return to the initial position, so as to move the second transparent film corresponding to the (n+1)th packaging box in real time, thereby ensuring the continuous operation of the strip box transparent film packaging production line.

[0084] Step 104: When the nth encapsulation box film is in the folding position corresponding to the folding mechanism, control the folding mechanism to fold the nth encapsulation box film, and control the first sealing mechanism to seal the nth encapsulation box film after the folding process.

[0085] Specifically, during the process of controlling the pushing mechanism to push the nth packaging film, when the control terminal detects that the nth packaging film is at the folding position corresponding to the folding mechanism, it indicates that the nth packaging film can be folded. Therefore, it can, but is not limited to, first controlling the pushing mechanism to stop pushing the nth packaging film, and then controlling the folding mechanism to fold the nth packaging film. It can be understood that the folding mechanism can be specifically divided into a lower folding plate folding device and an upper folding plate folding device, so that the lower folding plate folding device performs upward folding of the side containing the long side of the packaging film, and the upper folding plate folding device performs downward folding of the packaging film.

[0086] It should be noted that during the process of folding the nth packaging film by the folding mechanism, the control terminal can also continue to determine whether the (n+1)th packaging box is in a designated position. If the (n+1)th packaging box is determined to be in the designated position, the pusher mechanism can be controlled to push the (n+1)th packaging box along a preset path. During this pushing process, if the (n+1)th packaging box is within the cavity of the corresponding transparent film, a continuous pushing force can be applied to the (n+1)th packaging film composed of the (n+1)th packaging box and the corresponding transparent film. Furthermore, before the nth packaging film completes its folding process, the (n+1)th packaging film continues to move along the preset path under the pushing force of the pusher mechanism. Even after the nth packaging film completes its folding process, the (n+1)th packaging film continues to move along the preset path, effectively ensuring the continuity of the entire packaging production line.

[0087] Furthermore, after the folding mechanism folds the nth packaging film, the control terminal can also control the first sealing mechanism to seal the side where the long side of the overlapping transparent film is located. Here, when controlling the first sealing mechanism to perform the sealing process, it is possible, but not limited to, first controlling the first sealing mechanism to be in a designated sealing position, and relying on the top rod to swing the heating plate by about 10-15°, and then using the heating plate to seal the overlapping transparent film, and it is not limited to this.

[0088] As another optional embodiment of this application, before controlling the first sealing mechanism to perform sealing treatment on the nth packaging film after edge folding, the method further includes:

[0089] Acquire at least two second images containing the side of the nth encapsulation box film after edge folding, and identify transparent film contour feature points from each second image;

[0090] When the number of transparent film contour feature points corresponding to any second image is inconsistent with the number of transparent film contour feature points corresponding to other second images, abnormal feature points are selected from the transparent film contour feature points, and the sealing path is determined based on the abnormal feature points.

[0091] Controlling the first sealing mechanism to seal the nth packaging film after edge folding includes:

[0092] The first sealing mechanism is controlled to seal the nth packaging film after the edge folding process according to the sealing path.

[0093] Specifically, to improve the sealing efficiency of the first sealing mechanism, before controlling the first sealing mechanism to seal the nth encapsulation film after edge folding, the control terminal can, but is not limited to, acquire at least two second images containing the side of the nth encapsulation film after edge folding. Each second image contains a different side of the nth encapsulation film, and the transparent film contour feature points can be identified from each second image. Here, the transparent film contour feature points can be understood as all vertices corresponding to the transparent film contour features, or all vertices corresponding to the transparent film contour features and all intersection points of the transparent film contour features.

[0094] Next, when the number of transparent film contour feature points corresponding to any second image is inconsistent with the number of transparent film contour feature points corresponding to other second images, it indicates that the transparent film contour feature points corresponding to the second image contain feature points of the overlapping part of the transparent film (i.e., abnormal feature points). Then, all feature points in the transparent film contour feature points corresponding to the second image that are identical to those corresponding to any other second image can be filtered out. The remaining feature points are all intersection points of the transparent film contour features, i.e., feature points corresponding to the overlapping part of the transparent film (abnormal feature points). These feature points are then analyzed to obtain the sealing path. When analyzing the feature points corresponding to the overlapping part of the transparent film, it is not limited to using four feature points as an example. Any two opposite feature points can be used as the starting and ending positions in the sealing path, and the straight-line distance between these two opposite feature points can be used as the sealing movement distance in the sealing path. This is not a limitation.

[0095] Step 106: Obtain the distance between the (n+1)th encapsulation film and the nth encapsulation film after hot stamping. When the distance is detected to be within a preset distance range, control the corner folding mechanism to fold the nth encapsulation film after hot stamping, and control the second hot stamping mechanism to hot stamp the nth encapsulation film after corner folding.

[0096] Specifically, after the nth encapsulation film is heat-sealed, the control terminal can control the pushing mechanism to continue pushing the nth encapsulation film (the pushing force is less than the pushing force applied by the pushing mechanism when pushing the (n+1)th encapsulation film), or keep the nth encapsulation film stationary, or have the nth encapsulation film moved by other conveying devices. The control terminal can, but is not limited to, obtain the straight-line distance between the (n+1)th encapsulation film and the nth encapsulation film after heat sealing through the top camera. When the straight-line distance is determined to be within a preset distance range, it indicates that the distance between the (n+1)th encapsulation film and the nth encapsulation film after heat sealing is relatively close. Therefore, the control terminal can first keep the nth encapsulation film stationary, and then control the cornering mechanism to perform cornering on the nth encapsulation film after heat sealing. At this time, the pushing mechanism continues to push the (n+1)th encapsulation film until the (n+1)th encapsulation film reaches the folding position corresponding to the folding mechanism. Here, the preset distance range can be, but is not limited to, 0-80 centimeters, and is not limited to this range.

[0097] It is understood that the cornering mechanism may include, but is not limited to, a device consisting of a folding plate and a corner folder, to form a corner by means of creases created on the transparent film by the folding plate and the corner folder. For example, a first corner may be formed by creases created by the folding plate and a second corner may be formed by creases created by the corner folder, but is not limited thereto.

[0098] Furthermore, after the nth packaging film is folded, the control terminal can also, but is not limited to, control the second sealing mechanism to seal the left and right sides (and the sides where the non-long side is located) of the packaging film after the folding. In this embodiment, it can also, but is not limited to, use a spot-heating packaging device to perform spot-heating on each side of the packaging film after the sealing treatment to make the packaging effect of the transparent film more secure, and use other sealing packaging devices to perform top and bottom shaping and sealing treatments and front and back beautifying sealing treatments on the packaging film after the spot-heating treatment to make the packaging effect of the transparent film of the strip box more beautiful. It is not limited to these.

[0099] As another optional embodiment of this application, after the pushing mechanism pushes the nth packaging box film composed of the nth packaging box and the first transparent film, the method further includes:

[0100] When the cylinder pressure value corresponding to the pushing mechanism is detected to be outside the preset pressure range, the pushing mechanism is controlled to stop pushing the nth encapsulation box film and a box jam warning signal is issued.

[0101] Specifically, to ensure the stability of the pushing force applied by the pushing mechanism to the packaging film, after the control terminal controls the pushing mechanism to push the nth packaging film composed of the nth packaging box and the first transparent film, it can also, but is not limited to, use a pressure detection device to detect the cylinder pressure of the cylinder pushing device corresponding to the pushing mechanism. When the cylinder pressure value is detected to be outside the preset pressure range, it indicates that there may be an abnormality in the cylinder pushing device corresponding to the pushing mechanism (such as cylinder jamming). Then, the pushing mechanism can be controlled to stop pushing the nth packaging film and a jamming warning signal can be issued to the staff to remind them to check and handle the cylinder pushing device corresponding to the pushing mechanism in a timely manner.

[0107] The third processing module 403 is used to obtain the distance between the (n+1)th packaging film and the nth packaging film after hot stamping, and when the distance is detected to be within a preset distance range, it controls the cornering mechanism to perform cornering on the nth packaging film after hot stamping, and controls the second hot stamping mechanism to perform hot stamping on the nth packaging film after cornering.
