It should be noted that, firstly, the cardboard that needs gluing can be placed on the front end of the conveyor belt 101 by an automatic feeding manipulator or manually, after the cardboard is placed on the conveyor belt 101, the cardboard flows along with the conveyor belt 101, and in the flowing process of the cardboard, the position of the cardboard is corrected by the flexible guide strips 104 arranged on both sides of the conveyor belt 101, so that the guiding effect is achieved, the situation that the cardboard deviates when flowing to the area position of the fixing mechanism is avoided, and the function of clamping and positioning the cardboard by the fixing mechanism is further influenced. In addition, the adjusting groove 105 is arranged on the adjusting strip 103, so that a user can adjust the relative position between the two adjusting strips 103 through the adjusting groove 105 according to the actual width of the paper board, and further adjust the width between the two flexible guide grooves 207 to adapt to paper boards with different width sizes, and the application range is wider.

As shown in fig. 4, 6, and 7, the fixing mechanism includes a slot seat 106, a partition plate 107 is disposed in the slot seat 106, the slot seat 106 is partitioned into a first cavity 108 and a second cavity 109 by the partition plate 107, a push-pull plate 201 is slidably connected in the first cavity 108, the push-pull plate 201 is fixedly connected to one end of a pull rod 202, the other end of the pull rod 202 penetrates through the first cavity 108 and extends to the outside of the slot seat 106, the other end of the pull rod 202 is fixedly connected to a clamping block 203, a guide plate 204 is fixedly connected to the pull rod 202 in the second cavity 109 area, an elastic spring 205 is sleeved on the pull rod 202 in the second cavity 109 area, one end of the elastic spring 205 is fixedly connected to a side wall of the second cavity 109, and the other end is fixedly connected to the guide plate 204.

It should be noted that, image information on the conveyor belt 101 is obtained in real time through the industrial camera 409, when the cardboard is identified by the industrial camera 409 to be at a preset clamping position, the conveyor belt 101 is controlled to stop rotating, then the magnetic strip 206 on the fixing mechanism is controlled to be energized, when the magnetic strip 206 is energized, magnetic force is generated by the magnetic strip 206, and the magnetic strip 206 attracts the push-pull plate 201 (the push-pull plate 201 is made of an iron material), so that the push-pull plate 201 is attracted to the magnetic strip 206, and in the process that the push-pull plate 201 is attracted to the magnetic strip 206, the push-pull plate 201 pushes the pull rod 202 to move, and in the process that the pull rod 202 moves, the guide plate 204 is driven to move, so that the guide plate 204 slides along the first cavity 108 to the side away from the partition plate 107, at this time, the elastic spring 205 is compressed, and in the process that in which the pull rod 202 moves, the clamping blocks 203 are pushed to the inner side of the conveyor belt 101, so that the clamping blocks 203 arranged at both sides of the conveyor belt 101 clamp both sides of the cardboard, thereby positioning the cardboard, and further preventing the cardboard from affecting the uniformity of glue applied when the cardboard is sprayed by the spray nozzle 502.

It should be noted that, after the cardboard is glued, the magnetic strip 206 is powered off, the magnetic strip 206 loses magnetic force after power is off, at this time, the magnetic strip 206 does not generate an adsorption force on the push-pull plate 201 any more, at this time, the compressed elastic spring 205 rebounds under the action of a rebounding force, in the process of rebounding of the elastic spring 205, the guide plate 204 is pushed to slide towards the side close to the partition plate 107, and the guide plate 204 drives the pull rod 202 to move together in the sliding process, so that the pull rod 202 pushes the push-pull plate 201 to move towards the side far away from the partition plate 107, so that the push-pull plate 201 resets, and the pull rod 202 also drives the clamping block 203 to move towards the outside of the cardboard conveying belt 101, so that the clamping block 203 no longer clamps the cardboard, the spacing of the cardboard is released, at this time, the conveying belt 101 is started, so that the conveying belt 101 drives the finished cardboard to move to the next station, and a new cardboard is conveyed to the fixing mechanism by the conveying belt 101, and the cardboard is glued in a sequential gluing cycle, thereby performing automatic detection.

Compared with the motor or cylinder fixing mechanism commonly used in the industry, the fixing mechanism has the advantages that the magnetic strip 206 and the elastic spring 205 are used for acting a power driving element, the number of formed parts is small, the assembly is easy, the manufacturing cost is low, the practicability is better, the control is easy, and the fixing mechanism is more suitable for an automatic production workshop.

It should be noted that, by providing the guide groove 207 and the guide block 208, the guide block 208 is limited when sliding in the second cavity 109, so as to limit the pull rod 202 and the clamping block 203, eliminate the influence of the magnetic force of the magnetic strip 206 and the stability of the resilience force of the elastic spring 205, avoid the situation that the clamping block 203 is displaced during the movement, and improve the reliability of the device.

It should be noted that, after the cardboard to be glued is fixed by the fixing mechanism, the processing system acquires the area position of the cardboard to be glued (i.e. the preset gluing position), then the control system controls the X-direction driving motor 305, the Y-direction driving motor 403 and the Z-direction driving motor 406 to execute corresponding control programs, so as to drive the industrial camera 409 and the spray head 502 to move to the preset gluing position, and then the industrial camera 409 captures image information of the preset gluing position, and then determines whether the glue spraying amount needs to be compensated and corrected when the preset gluing position is sprayed and glued according to the image information (the specific detection and determination method is described below), and then the spray head 502 is used to spray and glue the preset gluing position. For example, if the preset gluing position where the cardboard needs to be glued is the lower left corner and the upper right corner of the cardboard, firstly, the processing system obtains the preset gluing area and the preset gluing thickness needed by the lower left corner of the cardboard, then the control system obtains the gluing height at which the glue can cover the preset gluing area when the spray head 502 sprays the glue according to the preset gluing area information, and then the control system controls the Z-direction driving motor 406 to start up, so that the Z-direction driving motor 406 drives the threaded screw 407 to rotate, thereby driving the Z-direction slider 408 to move, thereby adjusting the spray head 502 to the gluing height, and simultaneously controls the X-direction driving motor 305 and the Y-direction driving motor 403 to start up, so that the X-direction driving motor 305 drives the X-direction gear 307 to rotate, thereby causing the X-direction gear 307 to roll on the X-direction rack 302, thereby causing the X-direction slider 304 to move on the X-direction guide rail 301; similarly, the Y-direction driving motor 403 drives the Y-direction gear to rotate, so that the Y-direction gear rolls on the Y-direction rack 309, and the Y-direction slider 402 can move on the Y-direction rail 308; thus, by controlling the X-direction driving motor 305 and the Y-direction driving motor 403 to execute corresponding control programs, the nozzle 502 can be driven to move to a position right above the lower left corner region, and at this time, the axis of the nozzle 502 coincides with the axis of the lower left corner region; and after the spray head 502 moves to the upper part of the lower left corner area, the image information of the lower left corner area is shot through the industrial camera 409, then whether the glue spraying amount needs to be compensated and corrected when the glue spraying and gluing are carried out on the lower left corner area is judged according to the image information (the specific detection and judgment method is shown below), if so, the preset glue gluing parameter is corrected and then glue spraying is carried out, if not, the lower left corner area is sprayed and glued according to the preset glue gluing parameter, at the moment, the pressure pump on the glue supply machine 501 is controlled to be started, so that the pressure pump pumps the glue stored on the glue supply machine 501 into the spray head 502 through the glue supply pipe 504, then the glue is further accelerated and pressurized in the spray head 502 and sprayed to the lower left corner area of the paperboard through the spray nozzle on the spray head 502, and then the gluing process is completed on the lower left corner area of the paperboard.

After the sizing on the lower left corner area of the paper board is finished, the sizing is carried out on the upper right corner area of the paper board. Similarly, the processing system obtains a preset gluing area and a preset gluing thickness required by the upper right corner area of the paperboard, then the control system obtains a gluing height at which the glue can cover the preset gluing area when the spray head 502 sprays the glue according to the preset gluing area information, and then the control system controls the starting of the Z-direction driving motor 406, so that the Z-direction driving motor 406 drives the threaded screw rod 407 to rotate, the Z-direction sliding block 408 is driven to move, and the spray head 502 is adjusted to the gluing height; then, the X-direction driving motor 305 and the Y-direction driving motor 403 are also controlled to execute corresponding programs, so that the nozzle 502 moves to a position right above the upper right corner area of the paper board, and the axis of the nozzle 502 coincides with the axis of the upper right corner area; and after the spray head 502 moves to the upper right corner area, shooting image information of the upper right corner area through the industrial camera 409, then judging whether compensation correction needs to be carried out on the glue spraying amount when the glue spraying is carried out on the upper right corner area according to the image information (a specific detection and judgment method is shown below), if so, correcting a preset gluing parameter and then spraying the glue, if not, spraying the glue on the upper right corner area according to the preset gluing parameter, controlling a pressure pump on the glue supply machine 501 to be started at the moment, enabling the pressure pump to pump the glue stored on the glue supply machine 501 into the spray head 502 through the glue supply pipe 504, further accelerating the pressurization of the glue in the spray head 502, spraying the glue to the upper right corner area of the paperboard through a nozzle on the spray head 502, and further completing the gluing process on the upper right corner area of the paperboard.

To sum up, the rubberizing height through adjusting shower nozzle 502 makes shower nozzle 502 when spraying glue, and glue can once spray and cover in the preset rubberizing area region of cardboard to once only accomplish the spraying rubberizing to presetting the rubberizing position, improve work efficiency, make the even more effectual spraying of glue on each preset rubberizing position, and then improve the spraying quality of glue, and can adjust shower nozzle 502's spraying height through Z to driving motor 406, in order to the spraying area to the difference, application scope is wider.

As shown in fig. 12, the glue spraying amount control mechanism 503 can control the glue spraying amount of the nozzle 502 in unit time, the glue spraying amount control mechanism 503 includes a fixed wall 505 and a movable wall 506, a gap 507 with a preset size is left between the fixed wall 505 and the movable wall 506, a plurality of telescopic rods 508 are arranged between the fixed wall 505 and the movable wall 506, one end of each telescopic rod 508 is fixedly connected with the fixed wall 505, and the other end is fixedly connected with the movable wall 506.

The fixed wall 505 is made of alloy steel material, the movable wall 506 is made of rubber material, a vent pipe 509 is inserted between the gaps 507, one end of the vent pipe 509 penetrates through the fixed wall 505 and extends out of the gap 507, and a fine adjustment air pump 601 is connected to the vent pipe 509 extending out of one end of the gap 507 in a matching mode.

It should be noted that the glue spraying amount control mechanism 503 can control the pressure of the glue entering the nozzle 502 in the glue supply pipe 504, further control the speed of the glue sprayed from the nozzle 502, and further control the glue spraying amount of the nozzle 502 in unit time. Specifically, when the glue spraying amount of the nozzle 502 in unit time needs to be increased, the fine adjustment air pump 601 is controlled to be started, a certain volume of outside air is pumped into the gap 507 between the fixed wall 505 and the movable wall 506 through the fine adjustment air pump 601, after the certain volume of outside air enters the gap 507, the movable wall 506 expands and expands for a certain distance to the side far away from the fixed wall 505, and the telescopic rod 508 is driven to extend for a certain length in the expansion and expansion process of the movable wall 506, so that the space volume formed between the movable walls 506 is reduced, at this time, when glue flows through the glue spraying amount control mechanism 503, the glue is compressed, the pressure and the flow rate of the glue entering the inside of the nozzle 502 are increased, the spraying speed of the glue sprayed by the nozzle 502 is increased, and thus the glue spraying amount sprayed by the nozzle 502 in unit time is increased; similarly, when the amount of glue sprayed by the nozzle 502 in unit time needs to be reduced, the fine adjustment air pump 601 is controlled to be started, air in the gap 507 with a certain volume is pumped out to the external environment through the fine adjustment air pump 601, after the air in the gap 507 with a certain volume is pumped out to the external environment, the movable wall 506 contracts for a certain distance to the side close to the fixed wall 505, and the telescopic rod 508 is driven to shorten for a certain length in the contraction process of the movable wall 506, so that the space volume formed between the movable walls 506 is increased, when the glue flows through the glue spraying amount control mechanism 503, the glue is further expanded, the pressure of the glue is reduced, the pressure and the flow rate of the glue entering the nozzle 502 are reduced, the spraying speed of the glue sprayed by the nozzle 502 is reduced at the moment, and thus, the glue spraying amount sprayed by the nozzle 502 in unit time is reduced. In summary, the glue spraying amount of the spray head 502 in unit time can be controlled by the glue spraying amount control mechanism 503 to meet different gluing process requirements, and the application range of the device is widened; on the other hand, the spraying speed of the glue when the nozzle 502 sprays the glue is controlled by the glue spraying amount control mechanism 503, so as to avoid the condition of glue splashing, specifically, when the nozzle 502 sprays the glue at a lower glue spraying height (the distance between the bottom of the nozzle 502 and the top of the paperboard), if the spraying speed of the glue at the nozzle 502 is too high, at this time, because the distance between the nozzle 502 and the paperboard is short, the speed of the glue at the moment of contact between the paperboard and the paperboard is too high, and because the speed of the glue at the moment of contact between the glue and the paperboard is too high, the momentum of the glue falling on the paperboard is too high, and the distance of the glue splashing around the paperboard is too high, so that the condition of glue splashing is caused, the uniformity of the glue on the paperboard is poor, even the glue is splashed into a non-glue-spraying area, so as to cause a serious influence on the glue quality of the paperboard, therefore, when the nozzle 502 sprays the glue at a lower glue spraying height, the proper speed of the glue sprayed by the glue spraying amount control mechanism 503 is adjusted to be low, so as to avoid the condition of glue splashing; if the nozzle 502 is spraying glue at a higher glue applying height, the speed of the glue sprayed at the moment of contact between the paperboard and the paperboard is relatively small due to the relatively large distance between the nozzle 502 and the paperboard, the momentum of the glue falling on the paperboard is relatively small, and the glue splashing condition is not easily caused, so that the proper speed of the glue sprayed by the nozzle 502 can be increased by the glue spraying amount control mechanism 503, the glue spraying amount of the nozzle 502 in unit time is properly increased, the glue applying speed of the nozzle 502 is increased, and the production efficiency is improved.

and transmitting the actual gluing parameter value to a control system.

It should be noted that, in the same cardboard, there may be one or more than one preset gluing position, and the preset gluing area and the preset gluing thickness of each preset gluing position may be the same or different, and these parameters are set in advance by the technician. Therefore, before the paperboard is glued, a preset gluing position of the paperboard to be glued and a preset gluing parameter value corresponding to the preset gluing position are obtained, and then the position of an area needing gluing in the paperboard, the corresponding preset gluing area and the preset gluing thickness are obtained; then, determining the gluing height of the spray head for spraying glue on the preset gluing position according to the preset gluing area; and acquiring real-time image information of a preset gluing position through an industrial camera, and carrying out denoising, filtering and other modes on the image by using methods such as a nonlinear filter, a median filter, a morphological filter and the like so as to obtain a defect parameter value of a preset defect. The preset defect is a recess with preset size, shape, depth, width and length, and the defect parameter values comprise the length value, the depth value and the width value of the recess.

judging whether the defect parameter value is larger than a preset threshold value or not; if so, establishing an actual three-dimensional gluing model based on the defect parameter value and a preset gluing parameter value;

It should be noted that the preset defect type image is image information of depressions in the paper boards with various shapes and sizes. The preset three-dimensional gluing model is an ideal simulation three-dimensional model diagram which is established after glue spraying is carried out on the preset gluing position without any defects according to preset gluing parameter values under the condition that no preset defects exist in the preset gluing position, and in brief, the preset three-dimensional gluing model is an ideal simulation three-dimensional model after gluing is carried out on the preset gluing position under ideal conditions (no depression exists), and the model is a simulation model after gluing is carried out on the preset gluing position under ideal conditions. The actual three-dimensional gluing model is an actual simulation three-dimensional model diagram which is established based on the defect parameter values of the defects after glue spraying after the defects actually existing in the preset gluing position are obtained through an industrial camera, in brief, the actual three-dimensional gluing model is an actual simulation three-dimensional model which is established based on the defect parameters after the defect parameters are obtained, and the model reflects a simulation model which is glued to the preset gluing position under the actual condition. It should be noted that the three-dimensional model map can be created by 3D simulation modeling software such as SolidWorks software, maya software, pero software, UG software, and the like. The preset area, which is determined on the basis of the flowability, consistency and viscosity of the glue, is set in advance by the skilled person and represents the limit flow capacity per unit volume of glue on the board.

It should be noted that, due to the processing technology, the storage environment, and other reasons, there are often some depressions on the surface of the paperboard, and due to the depressions, when the spray head sprays glue on the surface of the paperboard, a part of the glue can permeate into the depressions, so when spraying glue on the paperboard, if the depression is not considered, the preset gluing parameter value is still adopted to spray and glue on the paperboard, which may cause the condition that the thickness of glue sprayed on the paperboard is not good, and the glue spraying area is uneven, thereby reducing the glue spraying qualification rate, and causing great economic loss. Therefore, in the present invention, before spraying and gluing the preset gluing position of the paperboard, whether the preset gluing position has the preset defect needs to be detected, and then whether the preset gluing parameter value needs to be corrected is determined. Specifically, firstly, preset defect type image information is obtained through a big data network, and a defect identification database is established; then, importing the real-time image information of the preset gluing position into the defect identification database, identifying whether a preset defect exists in the real-time image information, and if so, acquiring a defect parameter value of the preset defect in the real-time image information; when the defect parameter value is greater than the preset threshold value, it can be stated that if the original parameter (the preset gluing parameter value) is always maintained to spray glue on the paperboard, the existence of the defects may cause the unqualified conditions such as too small glue spraying thickness, concave glue spraying area, and the like, so that the preset gluing parameter value needs to be compensated and corrected. At the moment, an actual three-dimensional gluing model and a preset three-dimensional gluing model are established through 3D simulation modeling software; and comparing and analyzing the actual three-dimensional gluing model and the preset three-dimensional gluing model in the 3D simulation modeling software, and further analyzing the volume difference of the actual three-dimensional gluing model and the preset three-dimensional gluing model in each preset area, wherein the volume difference is the glue compensation quantity which can eliminate the influence of the depression on the spraying thickness in the preset area. It should be noted again that the compensation amount required by the glue is not equal to the volume of the recess, because the glue has a certain viscosity and fluidity, the volume difference between the actual three-dimensional gluing model and the preset three-dimensional gluing model in each preset area needs to be analyzed by the 3D simulation modeling software, so that the required glue compensation amount can be determined.

It should be noted that, because the depressions in the preset gluing positions in the cardboard may exist in multiple positions, and the sizes and shapes of each depression may be different, the volume difference may exist in multiple numbers, and therefore, the largest volume difference in each preset area needs to be selected as a compensation reference for the glue compensation amount, so as to obtain the glue spraying amount required by compensating the preset gluing thickness for the preset area, and further determine the actual gluing parameters, thereby ensuring that all the preset areas in the preset gluing positions can compensate the preset gluing thickness, eliminating the influence caused by the depressions in each preset area, avoiding the situation that the glue spraying thickness is not qualified in each preset area, effectively enabling the cardboard after glue spraying to reach the qualification standard, and improving the qualification rate of the cardboard after glue spraying.

In conclusion, before the paperboard is glued, the paperboard is subjected to defect detection firstly, so that the defect of glue spraying thickness of the paperboard after glue spraying is detected, the required glue spraying amount is compensated and corrected according to the parameter information of the defects, the influence caused by the defect existing on the paperboard is eliminated, the condition that the glue spraying thickness is unqualified is avoided, the paperboard after glue spraying is effectively enabled to reach the qualified standard, and the qualified rate of the paperboard after glue spraying is improved.

and controlling the starting of the Z-direction driving motor based on the gluing height of the spray head when the preset gluing position is glued, and then adjusting the spray head to the actual gluing height.

It should be noted that, due to the characteristics of the nozzle, the areas that the nozzle can spray at different gluing heights are different, so that the spraying areas corresponding to the nozzle at different gluing heights are obtained through the big data network, and a database is established; then acquiring a preset gluing area of a preset gluing position; in will predetermine the rubberizing area and leading-in the database, just can obtain the rubberizing height when the shower nozzle is to predetermineeing the rubberizing position rubberizing according to this predetermine the rubberizing area, then control Z to driving motor starts, and then adjusts the shower nozzle to actual rubberizing height, and like this, the shower nozzle just can once only cover this predetermines the rubberizing position when spouting the glue to this predetermine rubberizing position, has realized the function of disposable spraying glue.

comparing the glued three-dimensional model picture with the specimen three-dimensional model picture to obtain a deviation ratio;

and judging whether the deviation rate is greater than a preset threshold value, and if so, executing a repairing program.

The method comprises the steps that image information glued at a preset gluing position in a paperboard is shot through an industrial camera, denoising processing is conducted on the image information, sparse feature points are obtained through feature point matching, then coordinate information of the sparse feature points is obtained, and sparse three-dimensional cloud data are generated based on the coordinate information of the sparse feature points; then performing dense extraction according to the sparse three-dimensional cloud data to obtain dense three-dimensional point cloud data information; then, a curved surface is established based on the dense three-dimensional point cloud data information, a glued three-dimensional model graph is established based on the curved surface, the establishment of the curved surface and the establishment of the three-dimensional model graph can be established through 3D simulation modeling software, then the glued three-dimensional model graph is compared with a specimen three-dimensional model graph to obtain a deviation ratio, if the deviation ratio is greater than a preset threshold value, the flatness of the glued position is poor, at the moment, a repairing program is executed, and a spray head is controlled to spray glue on the area with poor flatness for correction.

acquiring historical gluing image information of a gluing module through a big data network, and establishing an identification database based on the historical gluing image information of the gluing module;

Note that the history rubberized image information is image information when an abnormal condition occurs. In order to reduce the gluing reject ratio of the paperboard, when the gluing module works, the real-time working image information of the gluing module during gluing is obtained, the real-time working image information is guided into the identification database for identification and comparison to obtain the degree of conformity, if the degree of conformity is smaller than the preset degree of conformity, the gluing qualification rate is lower if gluing is still performed according to the original gluing parameters, and at the moment, the gluing parameters of the gluing module need to be compensated and corrected, so that the rejection rate is reduced.
